Chalk Hill Blue Aberrations

Due to the sheer number of named aberrations for some species, not all are shown on the species pages - only those for which corresponding images are available. This page, however, provides access to all of the named aberrations for a given species, where known and Goodson & Read (1969) is a key resource in this regard.

ab. addenda [a] (Bright & Leeds.Mon.Corid.1938.p.34.nom.preoc.Tutt.)

Underside of the forewings with an extra single black spot or dot at the top of the submedian row. Leeds gives this name and description from Tutt’s ab. addenda of icarus, apparently not knowing that Tutt had an ab. addenda in coridon which covers any number of extra dots.

ab. addenda [b] (Tutt.Ent.Rec.1909.21.p.300.,fig.Brit.Lep.XI.pl.2.f.4.)

= pluripunctae Courvoisier.(group name).Iris.1912.26.p.45.

The underside showing extra black dots, not dribbled together, and with or without white circles, in places where normally there are no such spots or dots.

ab. alba (Bright & Leeds.Mon.Corid.1938.pp.26 and 64.)

Superb white underside form. In the male sometimes so extreme that nearly the whole of the veins are also white. In the female the fore and hindwings are extensively white.

ab. albescens [a] (Cockerell. Proc.S.Lond.Ent.&.Nat.Hist.Soc.1887.p.99.)

The metallic ground colour replaced by white as in L. phlaeas ab. schmidti. This may possibly refer to the Spanish race albicans, misprinted albescens, but the name must stand with its description.

ab. albescens [b] (Bright & Leeds.Mon.Corid.1938.p.49.nom.preoc.Cockerell.)

Female. On the upperside of fore and hindwings extensive white or whitish.

ab. albesco (Bright & Leeds.Mon.Corid.1938.p.15.)

Male. On the upperside of the hindwings the upper black costal border is marked with white, or a whitish spot, spots, or line. An unnecessary name, practically all males show it.

ab. albicincta (Tutt.Brit.Butts.1896.p.167.,Brit.Lep.XI.p.29.pl.1.f.15.)

= antialbocincta (female) Bright & Leeds.Mon.Corid.1938.p.55.

Tutt’s first description says “female form with the discoidal spots edged with white, and streaks of blue on the hindwings”. This however is amplified in his Brit.Lep.XI.p.12 and p.29 where he says the spots of the forewings are edged with white. The figure shows the forewings discoidal ringed with white and no discoidal spot on the hindwings.

ab. albipuncta (Tutt.Brit.Lep.1910.XI.pp.12 and 29.pl.1.f.4.)

= circumscripta (female) Stauder.Deutsch.Ent.Z.1924.p.28.
= mixtaalbocincta (female) Bright & Leeds.Mon.Corid.1938.p.55.

Tutt describes a female in which the discoidal spots on the forewings are ringed with white and those of the hindwings similarly ringed or replaced by white spots so that all four discoidals stand out conspicuously in white. Stauder described his circumscripta as having the middle spots of all four wings round and white-surrounded. He then says he has 8 males and 14 females of this form. The female is a synonym of albipuncta Tutt but the male with such spots on the forewings and hindwings had not been named so may be kept separate under the name circumscripta. Leeds description is complete nonsense as usual, he says that for albipuncta the forewings must have only a white spot devoid of a black centre, otherwise it is albocincta Tutt and the hindwings must also show a white spot, without a black centre.

ab. albocentrijuncta (Bright & Leeds.Mon.Corid.1938.p.64.)

Female. Underside of forewings with white streak from the base, or near to it, to the discoidal spot, or beyond, narrowly, to the outer border. Hindwings show no white..

ab. albocrenata (Tutt.Brit.Lep.1910.XI.pp.10 and 11.)

Male. Forewings with narrow black border having its inner edge marked off in a series of whitish lunules. The ground colour bright silvery blue. Described as a male form only.

ab. albocrenata-pallidula (Tutt.Brit.Lep.1910.XI.p.11.)

Male. Forewings with narrow blackish border, the spots on its inner edge only appearing as whitish marginal lunules. The ground colour pale silvery-blue.

ab. albocrenata-viridescens (Tutt.Brit.Lep.1910.XI.p.12.)

Male. Forewings with narrow blackish border, the spots on its inner edge only appearing as whitish marginal lunules. The ground colour pale silvery-blue.

ab. albocuneata [a] (Bright & Leeds.Mon.Corid.1938.pp.21 and 56.nom.preoc.Wagner.1926.)

Male and female. Similar to albolunulata Tutt but the whitish crescents on the inner side of the orange border spots are in the form of wedges instead of mere crescents. Leeds credits Tutt with authorship but Tutt’s form was in icarus.

ab. albocuneata [b] (Wagner.Z.Ost.Ent.Ver.1926.11.p.4.)

Female. The forewings appear to be normal male but the hindwings are grey-brown with a little blue at the base and showing the suavis character. There is a large and longitudinal black spot and two small spots in the middle of the wing but the most striking character is the wedge of pure white reaching from the margin to the discoidal black spot or spots. Wagner says that at first sight the insect appears to be a male, but may be a gynandromorph because of the markings of the hindwings. The example is extremely similar as regards the discoidal marks and long wedge of oberthuri. Whether or not the forewings are really male, or merely of the syngrapha type, it is difficult to decide but Wagner would presumably have known a syngrapha blue which is not nearly so silvery as a normal male blue. In any case the wedge is pure white not silvery blue as in oberthuri Gelin.

ab. albodescens (Bright & Leeds.Mon.Corid.1938.p.52.)

Female. The marginal lunules on the upper or underside white instead of orange. One of the few good forms named by Leeds, it must be a rare aberration.

ab. albofimbriata (Tutt.Brit.Lep.1910.XI.p.11.pl.1.f.3.)

= albofimbriata Stauder.Deutsch.Ent.Z.1924.p.28.

On both fore and hindwings the fringe shows no chequerings or divisions. Upper or underside form.

ab. albolunulata (Tutt.Brit.Lep.1910.XI.p.12.,see fig.South.Entom.20.pl.1.f.11.)

Female. With whitish secondary crescents surmounting the black border edging the inner side of the orange lunules of the hindwings and extending to the forewing in the form of curved whitish spots, either a single or double row. The ground colour brown with no blue scales. Leeds has altered Tutt’s description completely and says that the whitish crescents are on the hindwings only and that when on the forewings as well they are ultraalbocrenata.

ab. albomaculae (Bright & Leeds.Mon.Corid.1938.p.57.)

Female. On the upperside of both fore and hindwings a row of white spots situated midway between the outer border and the discoidal spot.

ab. albonigrofimbriata (Tutt.Brit.Lep.1910.XI.p.11.)

The fringes white edged with black. Tutt does not say whether or not all wings are affected, presumably it applies to both fore and hindwings.

ab. alboparallela (Bright & Leeds.Mon.Corid.1938.p.64.)

Female. Underside of forewings with two white streaks, or white band, from the discoidal spot to the second and third submedian spots. This white may extend in one or both directions and become somewhat broadly white from the base to the outer border. Hindwings showing no white.

ab. alboradia (Bright & Leeds.Mon.Corid.1938.p.28.)

Male and female. On the underside of the hindwings white radiations along the veins or a large patch of white.

ab. alternafimbriata (Bright & Leeds.Mon.Corid.1938.p.22.)

On the forewings fringes five broadly black or dark almost square markings, especially broad in the upper divisions. On upper or underside.

ab. angustimargo (Tutt.Brit.Lep.1910.XI.p.9.pl.1.f.5.)

Male. The black border very narrow on the bright silvery-blue ground.

ab. angustimargo-pallidula (Tutt.Brit.Lep.1910.XI.p.11)

Male. Pale silvery-blue ground with narrow black border without marginal spots. Forewing only.

ab. angustimargo-viridescens (Tutt.Brit.Lep.1910.XI.p12.)

Male. Pale silvery greenish-blue ground with narrow black border and without marginal spots. Forewing only.

ab. antialbescens (Bright & Leeds.Mon.Corid.1938.p.64.)

Female. The underside of the forewings with a largely white area from the basal spot to outer border chevrons, usually triangular in shape or may extend to almost entirely white. Hindwings showing no white.

ab. antialbofimbriata (Bright & Leeds.Mon.Corid.1938.p.22.)

On the forewings the fringe shows no chequerings or divisions. Hindwings normal.

ab. antialbomaculae (Bright & Leeds.Mon.Corid.1938.p.57.)

ab. antialbopuncta (Bright & Leeds.Mon.Corid.1938.pp.14 and 55.)

Male. Forewings with a whitish discoidal spot, devoid of a black centre. Female similar.

ab. antiaurantiaextensa (Bright & Leeds.Mon.Corid.1938.p.53.)

Female. On the forewings one or more of the orange marginal lunules unusually long inwardly, or wedge shaped. Some may extend into the discoidal area. Applies also to the underside.

ab. antiaurodifferentiae (Bright & Leeds.Mon.Corid.1938.p.53.)

Female. The forewings showing orange marginal lunules different in size or number on opposite wings asymmetrically. Applies also to the underside.

ab. antibiirregularia (Bright & Leeds.Mon.Corid.1938.pl.2.f.23.)

Female. The forewings of a different colour from those of the hindwings.

ab. anticaerumaculae (Bright & Leeds.Mon.Corid.1938.p.57.)

Female. On the upperside of the forewings a row of blue spots situated midway between the outer border and the discoidal spot.

ab. anticaerupuncta (Bright & Leeds.Mon.Corid.1938.p.55.)

Female. Showing a blue discoidal spot on the forewings only, devoid of a black centre.

ab. anticentrijuncta (Bright & Leeds.Mon.Corid.1938.p.38.)

Underside of the forewings with one or more of the basal spots connecting with the discoidal spot, forming a streak or streaks.

ab. antico-discreta (Tutt.Brit.Lep.1910.XI.pl.2.fig.3.)

= antidiscreta Bright & Leeds.Mon.Corid.1938.p.34.

Tutt did not describe this in the text but on his plate separated ‘discreta’ into two forms - discreta for both fore and hindwings and antico-discreta for forewings only. This latter, on plate 2, figure 3, shows the submedian spots of the forewings thrown outwards away from the discoidal spot against the marginal spots.

ab. antico-extensa (Tutt.Brit.Lep.1910.XI.p.39.pl.2.f.12.)

= antidiscoelongata Bright & Leeds.Mon.Corid.1938.p.40.

Underside of the forewings with all spots, except the discoidal, absent. Hindwings normal.

ab. anticoextensa-obsoleta (Tutt.Brit.Lep.1910.XI.p.39.)

Underside of the forewings with the submedian spots extended into streaks and the hindwings with all spots, except the discoidal, absent.

ab. anticrassilunulata [a] (Bright & Leeds.Mon.Corid.1938.pp.30 and 54.)

Forewings with the discoidal spot larger or more downward lengthened. Described first as a male underside but occurs on upper and underside of the female.

ab. anticrassilunulata [b] (Bright & Leeds.Mon.Corid.1938.pp.30 and 70.)

Underside of the forewings with the discoidal spot larger or more downward lengthened than the discoidal spot of the opposite wing, or with both discoidal spots larger. Also described as an upperside form.

ab. anticrassipuncta (Bright & Leeds.Mon.Corid.1938.p.34.)

Underside of the forewings with the spots much enlarged.

ab. anticuneata (Bright & Leeds.Mon.Corid.1938.p.19.)

Male. On the forewings the marginal spots are wedge-shaped, some or all, in extreme forms extending from near the fringe with their points ending in the blue ground colour.

ab. antidecrescens (Bright & Leeds.Mon.Corid.1938.p.21.)

On the forewings the outer border shows less divisions than normal. Hindwings normal.

ab. antidiscoidalisnulla [a] (Bright & Leeds.Mon.Corid.1938.pp.31 and 54.)

The forewings devoid of a discoidal spot. Other spots normal. Described as male underside and upper and underside of female.

ab. antidiscoidalisnulla [b] (Bright & Leeds.Mon.Corid.1938.p.31.)

Underside of the forewings with the discoidal spots absent. Also described as an upperside form.

ab. antidiscoradiata (Bright & Leeds.Mon.Corid.1938.p.41.)

Underside of the forewings with the discoidal spot connected through the submedian spots to the marginal chevrons by one or more streaks.

ab. antiextrema (Bright & Leeds.Mon.Corid.1938.p.42.)

Underside of the forewings with a basal spot connecting with the discoidal spot and continued, after branching, on through the submedian spots to reach the marginal ones in one or more streaks.

ab. antigriseofimbriata (Bright & Leeds.Mon.Corid.1938.p.22.)

On the forewings the fringes are grey. Hindwings normal.

ab. antiimpar (Bright & Leeds.Mon.Corid.1938.p.58.)

Female. Patches or spots of clouded blue standing out clearly from the rest of the ground colour on the forewings only.

ab. antiincrescens (Bright & Leeds.Mon.Corid.1938.p.21.)

On the forewings the outer border shows more divisions than normal. Hindwings normal.

ab. antimaculae (Bright & Leeds.Mon.Corid.1938.p.57.)

ab. antimixtaelongata (Bright & Leeds.Mon.Corid.1938.p.33.)

Underside of the forewings with elongated basal spots but different in number on the one side from those of the other.

ab. antiobsoleta (Bright & Leeds.Mon.Corid.1938.p.43.)

On the underside of the forewings one or more of the submedian spots, and sometimes one or both of the basal spots, are absent. Hindwings normal. This is not the same as antico-obsoleta Tutt which has no spots at all except the discoidal on the forewings. The name is so similar that it ought to be given another.

ab. antiobsoletissima (Bright & Leeds.Mon.Corid.1938.p.44.)

Underside of the forewings with all spots, including the discoidal, absent. Hindwings normal.

ab. antiparvipuncta (Bright & Leeds.Mon.Corid.1938.p.33.)

ab. antistriata (Bright & Leeds.Mon.Corid.1938.p.41.)

Underside of the forewings with a basal spot united with the discoidal spot and a single streak from the discoidal to either the second or third submedian spot.

ab. antitransiens (Bright & Leeds.Mon.Corid.1938.p.40.)

ab. antitransversa (Bright & Leeds.Mon.Corid.1938.p.42.)

Underside of the forewings with two or more of the submedian spots united transversely forming a downwards line or chain.

ab. antiultradiscreta (Bright & Leeds.Mon.Corid.1938.p.34.)

Underside of the forewings with the discoidal spot thrown outwards towards the margin. Sometimes the basal spots also follow this trend.

ab. antivacua (Bright & Leeds.Mon.Corid.1938.p.44.)

Underside with all markings on the forewings completely absent, except the veins. Hindwings normal.

ab. apicoextensa (Bright & Leeds.Mon.Corid.1938.p.35.)

Underside of the forewings with the top spot of the submedian row elongated.

ab. apicojuncta (Bright & Leeds.Mon.Corid.1938.p.39.)

Underside of the forewings with the first (topmost) submedian spot connected in a long streak with a marginal chevron. Tutt did not describe this form under coridon.

ab. arcuata-elongata (Saussie.Bull.Soc.Lep.Gen.1914.3.p.79.pl.1.f.2.)

Underside of the forewings with the lowest but one of the submedian spots united in a long streak with a basal spot which is situated much nearer the base than usual, consequently making the streak much longer than in the usual ‘arcuata’ forms.

ab. arcuata-i-nigrum (Bright & Leeds.Mon.Corid.1938.p.37.)

Underside of the forewings with the lowest submedian spots united with the basal to form two lines, the upper one being arc shaped, the lower one a straight line.

ab. arcuata-semi-i-nigrum (Bright & Leeds.Mon.Corid.1938.p.37.)

Underside of the forewings with the submedian spots united with basals to form two lines, the upper one a complete arc, the lower one however an interrupted straight line.

ab. arcuata-semiarcuata (Bright & Leeds.Mon.Corid.1938.p.37.)

Underside of the forewings with the lowest submedian spots uniting with the basals in two arcs, the upper one complete, the lower one interrupted.

ab. atrescens (Tutt.Brit.Lep.1910.XI.p.12.)

On the upperside females of a dark or blackish ground colour.

ab. aurantia (Tutt.Brit.Butts.1896.p.167.,Brit.Lep.XI.p.14.)

= aurantiaca Lambillion.Pap.Belg.1902.p.240.

Female. The marginal orange lunules well represented on both fore and hindwings, stronger on the latter. The ground colour brown with no blue scaling. Leeds includes the underside as well.

ab. aurantiaextensa (Bright & Leeds.Mon.Corid.1938.p.53.)

Female. On both fore and hindwings the orange marginal lunules are unusually long inwardly or wedge-shaped. Also applies to the underside.

ab. aurescens [a] (Tutt.Brit.Lep.1910.XI.p.19.)

= aurea Bright & Leeds.Mon.Corid.1938.p.29.

The underside with bronzy scales at the base of the hindwings. Leeds here makes his most stupid complication to literature. He drops the name aurescens given by Tutt and substitutes the name aurea, but uses aurescens for an entirely different form. See aurescens Leeds.

ab. aurescens [b] (Bright & Leeds.(nom.preoc.Tutt).Mon.Corid.1938.p.30.)

Male. Underside with reddish-orange lunules in the margin of the hindwings. See notes for aurescens Tutt.

ab. aurodifferentiae (Bright & Leeds.Mon.Corid.1938.p.54.)

Female. The fore and hindwings showing a different size or number or orange marginal lunules on opposite wings asymmetrically. Applies also to the underside.

ab. auronulla (Bright & Leeds.Mon.Corid.1938.p.30.)

The orange marginal lunules entirely absent. Occurs in female upperside and on the underside of both male and female.

ab. aurotithonus (Tutt.Brit.Lep.1910.XI.p.15.pl.1.f.19.)

Female. All wings scaled with blue as in tithonus (syngrapha) and showing well developed marginal lunules on all four wings.

ab. basicaeruleata (Tutt.Brit.Lep.1910.XI.pp.12 and 14.)

= basiradio Bright & Leeds.Mon.Corid.1938.p.47.

Female. The basal area of the wings strewn with blue scales and with no marginal lunules. Leeds changed Tutt’s name to basiradio.

ab. basiextrema (Bright & Leeds.Mon.Corid.1938.p.41.)

Underside of the forewings with the basal spot connected by a long streak along the inner margin to the marginal chevron, not via the discoidal spot.

ab. basijuncta (Tutt.Ent.Rec.1909.21.p.300.,fig.Brit.Lep.XI.pl.2.f.7.)

= retrojuncta Courvoisier.Iris.1912.26.p.50.

Underside of the hindwings with the third basal spot united in a streak with the lowest of the submedians (the twin-spot).

ab. basijuncta-semiretrojuncta (Bright & Leeds.Mon.Corid.1938.p.38.)

Underside of the hindwings with the third basal united with the lowest submedian (basijuncta) and the fourth basal elongated downwards towards the last marginal chevron but not joining it (semiretrojuncta Bright and Leeds).

ab. bi-i-nigrum (Bright & Leeds.Mon.Corid.1938.p.36.)

Underside of the forewings with the two lowest submedian spots united with basal or basals, to form two lines, one directly above the other.

ab. biarcuata (Courvoisier.Z.Wiss.Ins.Biol.1907.p.35.pl.1.f.10.)

= biarcuata Tutt.Brit.Lep.1910.XI.p.18.

Underside of the forewings with the lowest submedian spots united with a basal or basals to form two arcs, one directly above the other.

ab. biarcuata-obsoleta (Tutt.Brit.Lep.1910.XI.pl.2.f.17.)

Underside of the forewings of the biarcuata type with two arcs just above the inner margin, and the hindwings with the spots strongly reduced. Not described in the text.

ab. bibasijuncta (Bright & Leeds.Mon.Corid.1938.p.38.)

Underside of the hindwings with two complete streaks in the same area as basijuncta Tutt. It is like basijuncta with another streak just above it, or below it, and running parallel.

ab. biirregularia [a] (Bright & Leeds.Mon.Corid.1938.p.51.)

Female upperside. A wing or wings on the one side different in colour from those of the opposite side. First described as an underside form.

ab. biirregularia [b] (Bright & Leeds.Mon.Corid.1938.pp.28 and 68.)

Male and female. Underside with the wings fully scaled, not bleached out, but different in colour on the one side from that of the opposite side. This form is also described as an upperside female.

ab. bilineata (Tutt.Brit.Lep.1910.XI.p.17.)

= basielongata Courvoisier.Iris.1912.26.p.46.

An extension or development of ab. quadripuncta Courvoisier which has four basal spots. Two of these become lines or streaks, the other two remaining as spots. Sometimes both pairs become lines, forming two streaks instead of four spots.

ab. brunnescens [a] (Tutt.Brit.Lep.1910.XI.p.12.)

Tutt states that females of a brown colour are brunnescens and those of a dark to blackish colour atrescens. This brunnescens is therefore synonymous with the type form, which however was not actually described by Poda, only linked with the male and generally accepted as being merely brown.

ab. brunnescens [b] (Tutt.Brit.Lep.1910.XI.p.16.)

On the underside of the female the ground colour is usually brown rather than grey-brown, generally with more fully brown hindwings. Leeds includes males with the underside of fore and hindwings darker brown than type without the sandy appearance and with no tint of grey and credits Tutt with the authorship but Tutt’s brunnescens was for female (as above). The males with this brown tint Tutt called fulvescens.

ab. c-nigrum (Bright & Leeds.Mon.Corid.1938.p.38.)

Underside of the hindwings with the lowest submedian, the twin spots, united in the form of an inverted arc, or letter ‘C’ placed on its back. Tutt did not describe this form in coridon.

ab. caeruleo (Tutt.Brit.Lep.1910.XI.p.11.)

Male. The ground colour bright silvery blue.

ab. caeruleo-marginata (Tutt.Brit.Butts.1896.p.167.)

Male. Silvery-blue ground with broad dark unspotted borders or marginal bands. The same as marginata but with no distinct tint of green.

ab. caeruleoalbolunulata (Tutt.Brit.Lep.1910.XI.p.14.)

As in albolunulata but with blue at the base of the forewings and the hindwings blue from the base to the margins.

ab. caeruleocincta (Tutt.Brit.Lep.1910.XI.pp.12 and 29.)

= anticaerucincta Bright & Leeds.Mon.Corid.1938.p.55.

Female. The discoidal spots on the forewings ringed with blue.

ab. caeruleocuneata (Tutt.Brit.Lep.1910.XI.p.12.pl.1.f.13.)

= caerucuneata Bright & Leeds.Mon.Corid.1938.p.56.

Female. Blue wedge-shaped spots on the inner side of the marginal border.

ab. caeruleolunulata (Tutt.Brit.Lep.1910.XI.p.12.)

= ultracaerucrenata Bright & Leeds.Mon.Corid.1938.p.57.

Female. Blue crescents on the inner edge of the marginal orange lunules of the hindwings, extending to the forewings in a single or double row of curved blue spots. Leeds apparently did not like Tutt’s name for this form.

ab. caeruleoperaurantia (Tutt.Brit.Lep.1910.XI.p.14.)

Female. As in peraurantia Tutt but with the fore and hindwings both showing blue scaling at the base of the wings.

ab. caeruleopuncta (Tutt.Brit.Lep.1910.XI.p.12.)

= caerucincta Bright & Leeds.Mon.Corid.1938.p.55.
= mixtacaerucincta Bright & Leeds.Mon.Corid.1938.p.55.

Tutt is far from clear in his short description of this form. After mentioning albicincta and albipuncta in which the discoidals show white, he merely says – ocassionally the discoidals are blue-ringed (caeruleocincta) or blue-spotted (caeruleopuncta). The only assumption is that caeruleopuncta is the same as the description for albipuncta but the spots, and rings, are blue instead of white. Tutt apparently did not discriminate between rings and spots. On his plate he figures two examples of albipuncta one with the hindwings discoidal ringed with white and the other with a white blind spot. The only apparent difference is the fact that albicincta had the spots ringed on the forewings only whilst albipuncta had both fore and hindwings affected either with rings or just blind spots. Leeds can hardly be blamed in this case for getting things mixed.

ab. caeruleosubalbolunulata (Tutt.Brit.Lep.1910.XI.p.14.)

As in subalbolunulata but with blue at the base of the forewings and the hindwings blue from base to margins.

ab. caeruleosubaurantia (Tutt.Brit.Lep.1910.XI.p.14.)

Female. As in subaurantia with the orange marginal lunules well marked on the hindwings, but with the forewings and hindwings blue at the base.

ab. caeruleosubocellata (Tutt.Brit.Lep.1910.XI.p.14.)

Female. As in subocellata with the indistinct marginal spots faintly edged with greyish but the forewings and hindwings blue in the basal area.

ab. caerulineata (Tutt.Brit.Lep.1910.XI.p.13.)

= postcaerusignata Bright & Leeds.Mon.Corid.1938.p.58.

Female. On the upperside of the hindwings the usually whitish intermarginal line is replaced by blue.

ab. caerumaculae (Bright & Leeds.Mon.Corid.1938.p.57.)

Female. On the upperside of both fore and hindwings a row of blue spots situated midway between the outer border and the discoidal spot.

ab. caerupuncta (Bright & Leeds.Mon.Corid.1938.p.55.)

Female. The discoidal spot on both fore and hindwings in the form of a blue spot with no black centre. Leeds says caerupuncta is an abbreviated name for Tutt’s caeruleopuncta but his description is different so the form must stand as a new one.

ab. castanea (Tutt.Brit.Lep.1910.XI.p.16.)

Female. Underside of the hindwings coffee-coloured or chocolate-brown. The forewing may be similar. This would cover anything Leeds imagines in postultrafulvescens, all of his various tints would come under coffee or chocolate-brown.

ab. centrialbescens (Bright & Leeds.Mon.Corid.1938.p.64.)

Female. Underside of the forewings with a large white area between the basal and submedian spots almost or quite separated from the outer border. The ground colour, which surrounds it, gives a striking effect of central whiteness. Hindwings with no white.

ab. centrijuncta (Bright & Leeds.Mon.Corid.1938.p.79.)

Underside of both fore and hindwings showing a basal spot connecting with the discoidal spot. Courvoisier was not the author of this form in coridon as stated by Leeds.

ab. centriquinta (Bright & Leeds.Mon.Corid.1938.p.35.)

Underside of the forewings with the fifth submedian spot placed beneath the discoidal spot and elongated.

ab. chlorescens (Tutt.Brit.Lep.1910.XI.p.19.)

The underside with green basal scales on the hindwings.

ab. cincta (Tutt.Brit.Lep.1910.XI.p.10.)

Male. The marginal black spots of the hindwings entirely circled with whitish.

ab. cinereamargo (Bright & Leeds.Mon.Corid.1938.p.14.)

Male. Greyish, grey, or well-faded borders to the forewings

ab. cinnameus (Bright & Leeds.Mon.Corid.1938.p.11.)

Male. The borders very slightly lighter than cinnamon and this colour extends less pronounced over all the wings.

ab. cinnus-obsoleta (Tutt.Brit.Lep.1910.XI.pl.2.f.18.)

Underside of the forewings with the spots reduced, the hindwings with no spots. Not described in the text.

ab. confluens (Tutt.Brit.Lep.1910.XI.p.18.pl.2.f.11.)

Underside of the forewings with an arc like mark above the inner margin (arcuata) and on the hindwings the first basal spot united with the top submedian spot (costajuncta) and the third basal spot united with the last submedian (basijuncta). A combination form showing all three characters.

ab. coronetta (Tutt.Brit.Lep.1910.XI.p.19.)

Male. The underside of the pallida form, the orange lunules of the hindwings stand out like little jewels clearly and separately against the white ground. Leeds places this as a female upperside, which is ridiculous.

ab. corydonis (Bergsträsser.Icon.1779.2.pl.1.f.7-8.)

= cinnus Hubner.Samml.Eur.Schmett.1823-24.pl.167.f.831.
= sohni Ruhl.Soc.Ent.1893.7.p.190.
= privatissima Courvoisier.Mitt.Schweiz.Ent.Ges.1903.XI.p.25.pl.2.f.8.

Underside of both fore and hindwings with all spots, except the discoidals, absent.

ab. costaextrema (Bright & Leeds.Mon.Corid.1938.p.41.)

Underside of the hindwings with the first basal spot connected along the costa in a long streak to the marginal chevron.

ab. costajuncta (Tutt.Ent.Rec.1909.21.p.300.)

Underside of the hindwings with the first basal spot united with the first or top submedian spot in a streak.

ab. crassichevro (Bright & Leeds.Mon.Corid.1938.p.43.)

Underside of fore and hindwings, or just the forewings or the hindwings, with the marginal chevrons much enlarged standing out well from normal specimens.

ab. crassilunulata [a] (Bright & Leeds.Mon.Corid.1938.p.54.)

Female. On the upper or underside of the fore and hindwings the discoidal spots are large.

ab. crassilunulata [b] (Bright & Leeds.Mon.Corid.1938.p.71.)

Underside of fore and hindwings with the black discoidal spot larger and more downward lengthened. This is also described among the upperside forms.

ab. crassipuncta (Tutt.Brit.Lep.1910.XI.p.17.)

Underside with the basal, submedian and discoidal spots much enlarged. Tutt gives Courvoisier as the author but Courvoisier’s name was a group one ‘crassipunctae’. See Mitt.Schweiz.Ent.Ges.XI.p.19. and Vorbrodt Schmett.Schweiz.p.148. for Schemer by Courvoisier.

ab. cuneata (Tutt.Brit.Lep.1910.XI.p.10.)

= postcuneata Bright & Leeds.Mon.Corid.1938.p.19.

Male. On the hindwings the black spots in the margin wedge-shaped edged externally and along their sides with whitish. Leeds wrongly states that Tutt’s form was on all four wings.

ab. curvature (Bright & Leeds.Mon.Corid.1938.p.45.)

Underside of both fore and hindwings with the marginal chevrons and intersecting veins heavily dusted and together forming a strongly outlined series of arches, usually accompanied by the more or less absence of the black dots they normally enclose.

ab. decipiens (Crombrugghe.Rev.Mons.Soc.Ent.Nam.1911.p.45.)

= antialbocincta Bright & Leeds.Mon.Corid.1938.p.14.

Male. With the colour of the female ab. albicincta. The description is vague, albicincta was a female with the discoidal spot of the forewings ringed with white so presumably this male has a black discoidal point ringed with white. Leed’s antialbocincta was a male with the black discoidal point surrounded quite or almost by whitish. His female similar but this is ab. albicincta Tutt.

ab. decrescens (Bright & Leeds.Mon.Corid.1938.p.21.)

On both fore and hindwings the outer border shows less divisions than normal. Upper or underside form.

ab. dextro-obsoleta (Tutt.Brit.Lep.1910.XI.pp.18 and 37.)

Underside with the right wings obsolete, the left ones normal.

ab. discoidajuncta (Bright & Leeds.Mon.Corid.1938.p.39.)

Underside of the forewings with the third submedian spot connected with the discoidal spot in a streak. This was Courvoisier’s description of discojuncta, which however was not for use in coridon so Leeds description can stand for this form.

ab. discoidalis-duplex (Tutt.Brit.Lep.1910.XI.p.17.)

= bilunulata Bright & Leeds.Mon.Corid.1938.p.30.

Underside with the discoidal spot of the forewings shaped like an ‘8’ but split in the middle into two parts by a pale nervure. Leeds gives Courvoisier as the author of bilunulata but this is not so.

ab. discoidalisnulla [a] (Bright & Leeds.Mon.Corid.1938.pp.31 and 54.)

Both fore and hindwings devoid of a discoidal spot. Other spots normal. Described as male underside and upper and underside of female.

ab. discoidalisnulla [b] (Bright & Leeds.Mon.Corid.1938.p.31.)

Underside of all four wings with the discoidal spots absent. Also described as an upperside form.

ab. discojuncta (Bright & Leeds.Mon.Corid.1938.p.39.)

Underside of the forewings with the second submedian spot connected with the discoidal spot in a streak. Courvoisier was not the author in coridon.

ab. discoradiata (Bright & Leeds.Mon.Corid.1938.p.41.)

Underside of both fore and hindwings with the discoidal spot connected through the submedian spots to the marginal chevrons by one or more streaks.

ab. discreta (Tutt.Brit.Lep.1910.XI.p.16.pl.2.f.2.)

Tutt’s first description says the submedian spots of the forewings thrown back from the discoidal spot in an almost straight line against the marginal series. In his figure he shows both fore and hindwings with this character and the legend for the plate says that this is discreta and that when on forewings only it should be antico-discreta. From this it would be best to treat discreta as having the thrown outwards spots on both fore and hindwings.

ab. divisa (Tutt.Brit.Lep.1910.XI.p.10.)

Male. On the forewings the black border is divided by a whitish line down the greater length of it, formed by the inner edges of the marginal ocelli. Leeds on p.58 of his Monograph includes females with this same dividing line.

ab. divisa-pallidula (Tutt.Brit.Lep.1910.XI.p.11.)

Male. Pale silvery-blue ground with wide blackish border divided throughout by a pale line. Forewing only.

ab. divisa-viridescens (Tutt.Brit.Lep.1910.XI.p12.)

Male. Pale silvery greenish-blue ground with wide blackish border divided throughout by a pale line. Forewing only.

ab. elongata (Tutt.Brit.Lep.1910.XI.pp.18 and 38.)

Underside of the forewings with the basal spots in the form of one streak and one spot. Tutt gives Courvoisier as the author but Courvoisier’s name was elongatae, a group heading.

ab. excelsa (Tutt.Brit.Lep.1910.XI.p.15.)

Female. Of the tithonus (syngrapha) form but the fore and hindwings devoid of orange lunules.

ab. extensa (Tutt.Brit.Lep.1910.XI.p.39.)

= discoelongata Bright & Leeds.Mon.Corid.1938.p.40.

Underside of both fore and hindwings with the submedian spots elongated into wedges or short streaks pointing towards the discoidal spot but not reaching it. Leeds wrongly gives Courvoisier as the author of discoelongata and omits Tutt’s extensa altogether.

ab. extensa-discoidalis (Tutt.Brit.Lep.1910.XI.p.40.,fig.Mosley.pl.5.)

= centroelongata Courvoisier.Iris.1912.26.p.46.

Underside of the forewings with the discoidal spot apparently divided into two parts each forming a long streak towards the submedian spots. A third streak appears below these and the lower basal spot also forms a long streak. These various streaks do not join up with each other or any other spots.

ab. exteratransversa (Bright & Leeds.Mon.Corid.1938.p.42.)

Underside of the forewings with the small black marginal dots connected by a tranverse line. At least the second, third, fourth and fifth must be so connected.

ab. extrema (Bright & Leeds.Mon.Corid.1938.p.42.pl.10.f.4 and pl.18.f.9.)

Underside of both fore and hindwings with a basal spot connected with the discoidal spot and continued, after branching, through the submedians to reach the margin spots in one or more streaks. The two figures are somewhat different, one much more extreme than the other but both show more streaks than just those branching from the discoidal spot.

ab. flavescens (Tutt.Brit.Lep.1910.XI.p.14.)

= ultraflavescens Bright & Leeds.Mon.Corid.1938.p.52.

Female. The usually orange marginal lunules on all wings on the upperside are replaced by pale yellow. The underside similar. Leeds wrongly places this form in the suavis group, which are male forms. This is a female form only.

ab. fowleri (South.Entom.1900.33.p.104.pl.3.figs.4 and 5.)

= albomarginata Ebert.Iris.1926.40.p.36.

Male and female. The upperside of the forewings with white marginal border cut by the black veins to form squares, which however contain no black dots or pupils. These are present in ab. punctata Tutt. Hindwings with normal ocelli, perhaps less black than usual. Ebert described his form as having a broad pure white border, 2mm wide, cut by dark veins, and an extreme form of ab. punctata Tutt. He was not sure whether it was coridon or bellargus but it is almost certainly the former. Leeds description of fowleri is quite wrong. Tutt treats fowleri as having bright silvery-blue ground in the male, and names ab. fowleri-pallidula because it is of a paler blue etc.

ab. fowleri-margino (Bright & Leeds.Mon.Corid.1938.p.18.)

Forewings with the outer border showing one or two blind discs, the border is broad. Hindwings with one or more blind discs in the border.

ab. fowleri-pallidula (Tutt.Brit.Lep.1910.XI.p.11.)

Male. Pale silvery blue ground instead of bright silvery blue, otherwise like ab. fowleri South.

ab. fowleri-viridescens (Tutt.Brit.Lep.1910.XI.p.11.)

Male. Pale silvery greenish-blue ground, otherwise the same as ab. fowleri South.

ab. fulvafimbriata (Bright & Leeds.Mon.Corid.1938.p.60.)

Female. On both fore and hindwings the fringes have an effect of brightness, the best reaching a buff or even pinkish tint.

ab. fulvescens (Tutt.Brit.Lep.1910.XI.p.16.)

= postfulvescens Bright & Leeds.Mon.Corid.1938.p.27.pl.4.f.10 and 13.

Male. Underside of the hindwings with strongly tawny shading. Leeds alters the name because it is only a hindwing form.

ab. fumidescens (Bright & Leeds.Mon.Corid.1938.p.29.)

Underside with dark smoky scales at the base of the hindwings.

ab. furva (Bright & Leeds.Mon.Corid.1938.p.20.)

Male. On the hindwings one or two, rarely three, very dark brown (up to almost black) spots on the inner side of the black marginal spots as in suavis Schultz but devoid of the bright colour of that form.

ab. furvescens (Bright & Leeds.Mon.Corid.1938.p.53.)

Female upper or underside. The marginal lunules brownish, chocolate, or very dark.

ab. fuscamargo (Leeds.Mon.Corid.1938.p.14.)

Male. Brown, brownish or brownish-black outer borders to the forewings.

ab. fuscescens (Tutt.Brit.Lep.1910.XI.p.16.)

Male. The underside of the forewings dark grey. Hindwings distinctly tinged with brown. Leeds includes females of a similar colour.

ab. fuscofimbriata (Tutt.Brit.Lep.1910.XI.p.13.)

= fuscociliata Metschl.Ber.Nat.Ver.Regensburg.1916-23.16.p.81.
= antifuscofimbriata Bright & Leeds.Mon.Corid.1938.p.22.

Female. The fringes so heavily chequered and of such a dark ground colour that they are almost unicolorous on the forewings. Leeds includes males.

ab. glabrata (Tutt.Brit.Lep.1910.XI.p.9.)

Almost devoid of hair scales, exhibiting their shiny underscales. The normal silky look is absent.

ab. glomerata (Tutt.Brit.Lep.1910.XI.p.16.pl.2.f.6.)

= antiglomerata Bright & Leeds.Mon.Corid.1938.p.34.

Underside of the forewings with the submedian and basal spots drawn in towards the discoidal spot, forming a sort of semicircle around it. Leeds merely creates a synonym with his ‘anti’.

ab. grisea [a] (Tutt.Brit.Lep.1910.XI.p.9.)

Male. The ground colour pale grey, scarcely bluish. Leeds again wrongly attaches a female form to this on p.49 of his Monograph saying that it is paler than the type range, grey with barely a trace of brown. He also credits Tutt with the authorship of the underside forms of male and female which certainly have nothing to do with Tutt’s grisea. The underside male is the form which Tutt names fuscescens but Leeds ignores this. The ‘grisea’ names therefore on pages 18, 28 and 66 should not be used.

ab. grisea [b] (Bright & Leeds.(nee Tutt).nom.preoc.Tutt.Mon.Corid.1938.p.28.)

Male. Underside of the forewings darker than usual with no whitish diffusion, therefore grey or grey-brown. Hindwings also grey or grey-brown. The whole effect is darker than the type occasionally almost reaching the slaty colour of pulla. Tutt’s grisea was a male upperside and in no way related to this dark underside form. Leed’s name therefore is preoccupied.

ab. grisea-suavis (Tutt.Brit.Lep.1910.XI.p.9.)

Male. Like suavis Schultz with the inner edge of the marginal black spots tinged with fulvous but the ground colour pale grey.

ab. griseofimbriata (Bright & Leeds.Mon.Corid.1938.p.22.)

On the forewings and hindwings the fringes are grey.

ab. grisescens (Tutt.Brit.Lep.1910.XI.p.16)

= postgrisea Bright & Leeds.Mon.Corid.1938.p.28.

Male. The underside of the forewings whitish-grey. Hindwings tinged with greyish or yellowish-fawn.

ab. guedati (Reverdin.Bull.Soc.Lep.Gen.1924.5.p.63.)

Female. The upperside of the hindwings with the basal half greyish-green and showing a great reduction of the marginal ocelli.

ab. hafneri (Preissecker.Verh.zool.-bot.Ges.Wien.1908.p.68.)

Male with the ground colour like that of damon Schiff. (damon is described in Seitz as being of a brilliant sky blue.)

ab. i-nigrum (Tutt.Brit.Lep.1910.XI.p.43.)

Underside of the forewings with the lowest submedian spot united with a basal spot to form a straight line, not an arc. Tutt mentions this form but gives no author.

ab. i-nigrum-arcuata (Bright & Leeds.Mon.Corid.1938.p.36.)

Underside of the forewings with the lowest submedian spots united with basal spots to form two lines, the upper one a straight line, the lower one an arc.

ab. i-nigrum-semi-i-nigrum (Bright & Leeds.Mon.Corid.1938.p.36.)

Underside of the forewings with the lowest submedian spots united with basals to form two lines, the upper one a straight line, the lower one an interrupted straight line.

ab. i-nigrum-semiarcuata (Bright & Leeds.Mon.Corid.1938.p.36.)

Underside of the forewings with the lowest submedian spots united with the basals to form two lines, the upper one a straight line, the lower one an interrupted arc.

ab. impar (Cockayne.Trans.Ent.Soc.1916.p.243.)

= postimpar Bright & Leeds.Mon.Corid.1938.p.58.

Female form only. Patches of clouded blue or whitish blue standing out clearly from the rest of the wing, even when the wings are blue scaled. These patches are sometimes a mere spot, sometimes rather large and more than one on a single wing but apparently more frequent on the hindwings. The type shows the hindwings with several of these patches or spots. Leeds states that impar has patches on the forewings and gives the name postimpar to specimens with the patches on the hindwings only. Verity in Farf.Diurn.It.1.p.310 wrongly gives Cockerell as the author.

ab. impuncta (Courvoisier.Mitt.Schweiz.Ent.Ges.1903.XI.p.24.)

= clio Thierry-Meig.Le Nat.1910.32.p.167.

Underside of the forewings with the basal spots absent.

ab. inaequalis (Tutt.Brit.Butts.1896.p.167.)

Female form only. Streaks, patches or large sections of smooth shining bright blue or greenish scaling of unusual appearance on any part of a wing or wings. This is not male scaling and usually looks well polished. This form is not in any way like impar Cockayne in which the patches are not shiny or polished.

ab. increscens (Bright & Leeds.Mon.Corid.1938.p.22.)

On both fore and hindwings the outer border shows more divisions than normal.

ab. indistincta (Tutt.Brit.Lep.1910.XI.p.11.)

Male. Forewings with indistinct marginal ocellated spots, greyish in colour. The ground colour bright silvery blue.

ab. indistincta-viridescens (Tutt.Brit.Lep.1910.XI.p.11.)

Male. Pale silvery greenish-blue ground with indistinct greyish marginal ocellated spots. Forewing only.

ab. infraalbescens (Bright & Leeds.Mon.Corid.1938.p.65.)

Female. Underside of forewings with any form of white. Hindwings with streaks, radiations, a patch or patches of white but with no white on the costa.

ab. infraaurantia (Bright & Leeds.Mon.Corid.1938.p.52.)

Female. Only one small orange lunule, or barely the sign of a second one, in the margin of the hindwings and with the white circles or semicircles scanty or dingy. The forewing devoid almost or entirely of orange lunules.

ab. infralatiora (Bright & Leeds.Mon.Corid.1938.p.19.pl.5.f.17.)

Male. On the hindwings the black border more pronounced than usual, not so wide or black as in latiora, or, with black spots or chevrons on the blue ground interior to the ordinary black spots of the border which may be separated or joined up, but the general appearance of a very broad black outer border is not produced as in latiora. A very feeble aberration.

ab. infralavendula (Bright & Leeds.Mon.Corid.1938.pp.10 and 49.)

Male. The ground colour blue but distinctly tinted with lavender, lilav, mauve or lightish violet. The female dusted with the same tint.

ab. inframelaina (Bright & Leeds.Mon.Corid.1938.p.11.pl.5.f.21.)

Male. On the outer part of the forewings a heavily scaled black area but separated from the actual outer border by blue ground.

ab. infrasemialbescens (Bright & Leeds.Mon.Corid.1938.p.65.)

Female. Underside of forewings with white patches or streaks. Hindwings with white streak on the costa from the outer border to or beyond the first discal spot.

ab. infrasessilis (Bright & Leeds.Mon.Corid.1938.p.20.)

Male. On the hindwings almost all of the black marginal spots are linked with the black outer border, there being only very little intervening pale marking, such as a fine line, to not more than two of the spots other than the double anal ones. A feeble transitional form to ab. sessilis.

ab. irregularia (Bright & Leeds.Mon.Corid.1938.p.13.)

Male or female, upperside or underside. A spot, streak or patch of dark scaling on a wing or wings but not of a faded description.

ab. irregularis-obsoleta (Tutt.Brit.Lep.1910.XI.p.38.pl.2.figs.20 and 21.)

= irregularis Tutt.Brit.Lep.1910.XI.p.18.

On the underside one or three of the wings are of the corydonis (spotless) form, the other wing or wings almost or quite normal. Tutt on his plate calls this form irregularis-obsoleta and this has page priority over the name on page 18, which is merely irregularis. The name again becomes irregularis-obsoleta on page 38.

ab. juncta (Tutt.Brit.Lep.1910.XI.p.18.)

Underside of both fore and hindwings with extra spots as in ab. addenda Tutt, but united with the submedian spots to form black linear streaks pointing towards the discoidal spot. They are shaped like tadpoles producing a dribbled effect but never become a definite complete line or streak.

ab. khaki (Bright & Leeds.Mon.Corid.1938.p.49.)

Female. The wings khaki coloured with a mottled appearance consisting of innumerable tiny dark spots on a somewhat wainscot ground.

ab. lacticolor (Tutt.Brit.Lep.1910.XI.p.7.)

Pathological male. The fore and hindwings of a delicate cream colour. Leeds on p.49 of his Monograph adds the female as being of a very pale brownish or greyish wainscot with a misty appearance. Pathological examples appear through various causes such as pressure on the pupae and should not be named. Such a female, as Leeds couples with Tutt’s male, cannot in any way be related to anything.

ab. latiora (Bright & Leeds.Mon.Corid.1938.p.19.pl.5.f.20.)

Male. On the hindwings a very broad black border, the black encroaching well into the blue and quite beyond the normal black spots.

ab. lavendula (Bright & Leeds.Mon.Corid.1938.p.10.)

Male. The ground colour, lavender, lilac, violet or mauve, the blue tint almost absent. Female rare, dusted with lavender, light or dark.

ab. limbojuncta (Courvoisier.Iris.1912.26.p.50.)

Underside of the hindwings with the first submedian (topmost) spot connecting with a marginal chevron in a streak.

ab. linea (Bright & Leeds.Mon.Corid.1938.p.34.)

Underside of the forewings with the two lowest submedian spots placed directly beneath the discoidal spot, occasionally the spot above these two is also brought in. Tutt did not describe this form under coridon so is not the author as stated by Leeds.

ab. livida (Bright & Leeds.Mon.Corid.1938.p.10.)

Male. The ground colour varying from slightly darker than that of a dove, advancing through plumbeous, somewhat leaden-shaded, to the colour of a Wood Pigeon. The outer borders faded in the lighter specimens and others never have an actual black margin. Taken from the P. Icarus form livida Gillmer.

ab. lucretia (Gaschet.Bull.Soc.Ent.Fr.1877.Ser.5.p.LXIV.)

= obsoletissima Tutt.Brit.Lep.1910.XI.p.18.pl.2.f.13.
= caeca Courvoisier.Iris.1912.26.p.63.

The description of lucretia shows that it is the first name for specimens with all the underside spots absent, even the discoidal, which merely shows a white mark with no black spot.

ab. lunacuspidis [a] (Bright & Leeds.Mon.Corid.1938.pp.31 and 54.)

The forewings with the discoidal showing a point or points extending towards the margin, rarely towards the base. First described as a male underside but occurs on both upper and underside of the female.

ab. lunacuspidis [b] (Bright & Leeds.Mon.Corid.1938.p.31.)

Underside of the forewings with the black discoidal spot extended from or near the centre and ending in a short point, short streak or occasionally two short points. Described also as an upperside.

ab. lunaextensa [a] (Bright & Leeds.Mon.Corid.1938.pp.31 and 54.)

Forewings with a line or lines from the centre of the discoidal spot in one direction only, either towards the apex or towards the base but not joining another spot. First described as a male underside but occurs on both upper and underside of the female.

ab. lunaextensa [b] (Bright & Leeds.Mon.Corid.1938.p.31.)

Underside of forewings with the discoidal spot elongated in one direction at the top or bottom, or both, not joining up with any other spots. Also described as an upperside form.

ab. lunuco (Bright & Leeds.Mon.Corid.1938.p.15.)

Male. Forewings with a distinct discoidal spot and the hindwings with the common character of ab. albesco which has the upper costal black border marked with white.

ab. lunulata (Tutt.Brit.Lep.1910.XI.p.34.)

Female. As in syngrapha but the forewings only showing a discoidal point, the hindwings without a point. Leeds should not have included this form in ordinary female since it applies only to syngrapha.

ab. lutescens (Bright & Leeds.Mon.Corid.1938.p.53.)

Female upper and underside. The orange marginal lunules on the hindwings are replaced by pale orange. On the forewings it may tone down to yellow. Hardly worthy of a name.

ab. maculae (Bright & Leeds.Mon.Corid.1938.p.57.)

Female. On the upperside of both fore and hindwings a row of whitish or blue spots situated midway between the border and the discoidal spot. The spots can be white on the forewings and blue on the hindwings or vice versa, but must be of mixed colous, otherwise they belong to the albo or caeru forms of maculae.

ab. major (Tutt.Brit.Lep.1910.XI.p.15.)

Large specimens over 40mm.

ab. marginata (Tutt.Brit.Butts.1896.p.166.)

= inframarginata Bright & Leeds.Mon.Corid.1938.p.15.

Male. Bright silvery blue but with a distinct green tint and the forewings showing a distinct broad darker border. Hindwings with only faint dots. This is Tutt’s original description and must stand for the form marginata, no mention is made of the black continuing down the costa to the discoidal spot. Preissecker named this more extreme form in 1906 but in 1910 Tutt claimed that his marginata had the black increased strongly towards the costa and reaches to, or almost to, the discoidal point (pl.1.f.9. in Brit.Lep.XI.1910.). Tutt’s first description must stand and Preissecker’s seminigra is the name for the more extreme form.

ab. marginata-pallidula (Tutt.Brit.Lep.1910.XI.p.11.)

Male. Pale silvery-blue ground with wide blackish border extending suffusedly towards the disc and along the costa. Forewing only.

ab. marginata-viridescens (Tutt.Brit.Lep.1910.XI.p12.)

Male. Pale silvery greenish-blue ground with wide blackish border extending suffusedly towards the disc and along the costa. Forewing only.

ab. melaina (Tutt.Brit.Lep.1910.XI.p.25.)

Male. An extreme form of marginata Tutt. On the forewings the border is so wide that it extends beyond the discoidal cell and middle of the wing towards the base.

ab. metallica (Bright & Leeds.Mon.Corid.1938.pp.14 and 51.pl.1.f.24.)

Male. The wings with a roughish surface as if finely peppered with more or less darkish or even blackish colour, thus causing in most specimens a metallic effect. Female. Of rough texture and darker peppering.

ab. minor (Cockerell.Entom.1889.22.p.176.)

= minor Tutt.Brit.Lep.1910.XI.p.15.

Small specimens. Tutt gave below 32mm.

ab. minor-discreta (Tutt.Brit.Lep.1910.XI.pl.2.f.8.)

Very small example of discreta Tutt, the submedian spots thrown outwards away from the discoidal spot towards the margin. Not described in the text.

ab. minutissimus (Tutt.Brit.Lep.1910.XI.p.16.pl.1.f.2.)

Very small examples less than 25mm.

ab. mixtaalbocincta (Bright & Leeds.Mon.Corid.1938.pp.14 and 55.)

Male. On the forewings a black discoidal point ringed with whitish and on the hindwings a whitish discoidal without a black centre. This is kept separate from ab. albipuncta Tutt because Tutt only described it as a female form and this, a male, may possibly be not related to the same character in the female. The female however, which Leeds describes under this name, is the same Tutt’s albipuncta.

ab. mixtaalbopuncta (Bright & Leeds.Mon.Corid.1938.pp.14 and 55.)

Male. On the forewings a whitish discoidal spot devoid of a black centre and on the hindwings a black discoidal spot ringed with whitish. The female similar.

ab. mixtacaerupuncta (Bright & Leeds.Mon.Corid.1938.p.55.)

Female showing on the forewings a blue discoidal spot devoid of a black centre and the hindwings a black discoidal ringed with blue.

ab. mixtacincta (Bright & Leeds.Mon.Corid.1938.p.55.)

Female. With the discoidal spots asymmetrically scaled with white or blue. The forewings may be white scaled and the hindwings blue scaled or the colours intermixed so that they cannot be fixed to a one-colour form. The forewings must be ringed but the hindwings have either rings or spots or nothing. Another completely unnecessary name.

ab. mixtaelongata (Bright & Leeds.Mon.Corid.1938.p.33.)

Underside of both fore and hindwings with elongated basal spots but different in number on the one side from those of the other.

ab. mixtapuncta (Bright & Leeds.Mon.Corid.1938.p.56.)

Female. With the discoidal spots asymmetrically scaled with white or blue. The forewings can be white on one wing and blue on another or the colours so intermixed that they cannot be fixed to a one-colour form. The forewings however must be ringed with a colour but the hindwings have either rings, or spots, or nothing.

ab. mixtasuavis (Bright & Leeds.Mon.Corid.1938.p.21.)

Male. Both bright and dark, yellowish or brown, spots on the inner side of the black border spots of the hindwings.

ab. multipuncta (Bright & Leeds.Mon.Corid.1938.p.32.)

Underside of the forewings with six or more basal spots.

ab. neutra (Bright & Leeds.Mon.Corid.1938.p.11.)

Male. The wings brownish-drab or drab, thinly scaled. Very little difference from suffusa Tutt and unnecessary.

ab. nigrescens (Bright & Leeds.Mon.Corid.1938.p.67.)

Female. Underside of the hindwings blackish tinted up to black but with a brown shading and so different from postpulla. The colour of the forewings is immaterial. Another very feeble separation. See postpulla.

ab. nigrocostalis (Schulz.Jahresb.Wien.Ent.Ver.(1905)1906.16.p.77.)

Male. The costal area of the forewings blackened in width as far as the median nervure. Hindwings with a broad very black margin. Schultz does not say the outer borders of the forewings are wide, presumably these are normal. Tutt claims that it is the same as his marginata.

ab. nonarcuata (Bright & Leeds.Mon.Corid.1938.p.37.)

Underside of the forewings with erratic elongated markings between the submedian lowest spots and the basal ones in the same area as arcuata or i-nigrum, which cannot be definitely placed with any one form. Leeds by this was apparently determined to give every single coridon form a name.

ab. nubila (Bright & Leeds.Mon.Corid.1938.p.29.)

Male and female. Underside with a diffusion of dingy grey extending over a wing portion and in its area changing the colour of the white rings or the fringes. These are not bleached, or like the darker irregularia.

ab. oberthuri (Gelin.Bull.Soc.Ent.Fr.1914.p.184.pl.3.f.5.)

Female. The upperside of the syngrapha form, blue-scaled on all wings, but the interneural spaces on the hindwings are brown leaving the veins silvery blue. Also, on the hindwings, there is a strong black elliptical mark or short line running in the same direction as the veins, situated at the extremity of the discoidal cell and just below the discoidal point. These marks are enclosed in the middle of a trapezoidal space of very clear silvery blue sharply narrowed at its basal end and then prolonged in the form of a long wedge as far as the marginal lunules, becoming wider as it approaches the margin. The main feature of this form is the most unusual long silvery wedge reaching from the marginal lunules to the base of the hindwings and containing the elliptical black discoidal mark in its middle. It is coupled with the tithonus (syngrapha) character, otherwise it is very similar to albocuneata Wagner.

ab. obsolescens (Tutt.Brit.Lep.1910.XI.p.19.)

Underside with the markings in the margins practically obsolete except for faint grey traces of the chevrons, more often seen on the forewings than on the hindwings. The other spots of the underside normal.

ab. obsoleta (Tutt.Brit.Butts.1896.p.167.)

= paucipuncta Courvoisier.Iris.1912.26.p.63.

On the underside the spots tending strongly towards obsolescence. This presumably means on both fore and hindwings. Tutt did not mean without any spots at all since later in Brit.Lep.XI.p.18 he says ‘the spots considerably reduced until only the discoidal and marginal lunules are left when it becomes corydonis Bergsträsser’. Unfortunately he uses the same name ‘obsoleta’ for forewing and hindwing forms in which the spots are completely absent. Leeds further complicates matters by naming an ‘antiobsoleta’ and a ‘postobsoleta’ in which the spots are only reduced in number and not completely absent, therefore different from Tutt’s fore and hindwing obsoletas.

ab. ochracea (Frohawk.Vars.Brit.Butts.1938.pl.30.f.1.p.127.)

Female. The upperside of an ochreous colour, more or less buffish in tint. This is the form which Leeds couples with his male form cinnameus, he is wrong in assuming that because the male is cinnamon in cinnameus, a female of that tint must belong to the same male form, the two are unrelated.

ab. ochrea (Bright & Leeds.Mon.Corid.1938.p.27.)

Male. Underside of the hindwings strikingly ochreous-brown, the forewings less effectively so. Specimens with only the hindwings ochreous are not ochrea.

ab. olivacea (Bright & Leeds.Mon.Corid.1938.p.11.)

Male. Olive-brown, somewhat sparsely scaled wings, with very little blue showing, the margins brownish. Very little difference from suffusa Tutt.

ab. opposita (Tutt.Brit.Lep.1910.XI.p.32.)

Female. The forewings extensively blue-scaled, the hindwings with very little blue and therefore the reverse of the usual form.

ab. ornamenta (Bright & Leeds.Mon.Corid.1938.p.56.)

Female. Upperside of the forewings with any blue scaling restricted to the base of the wings or none at all. The discoidal spots showing any form of white or blue ornamentation and the hindwings showing white or blue crescents or wedges on the inner edge of the marginal lunules.

ab. pallida (Tutt.Brit.Lep.1910.XI.p.16.)

= albescens Bright & Leeds.Mon.Corid.1938.pp.27 and 66.

Male. The ground colour of the underside clear chalky-white, the hindwings with the faintest possible tinge of fawn. Leeds includes a female form with his albescens male with the fore and hindwings extensively chalky-white.

ab. pallidula [a] (Tutt.Brit.Lep.1910.XI.p.11.)

Male. The ground colour pale silvery blue. Female not described. Leeds under this name, and giving Tutt as the author, describes the female, which of course has no relationship with the pale male. Leeds also wrongly includes underside forms of the two sexes also giving Tutt as the author.

ab. pallidula [b] (Bright & Leeds.Mon.Corid.1938.pp.27 and 66.nom.preoc.Tutt.)

Distinctly paler than type, the paleness of the hindwings being the chief indication, pale grey or any other pale colour. This is not related to Tutt’s pallidula, which was an upperside male, the name is therefore preoccupied and cannot be used.

ab. parallela (Courvoisier.Z.Wiss.Ins.Biol.1907.3.p.36.pl.1.f.21.)

Underside of the forewings with two submedian spots connected with the discoidal spot in two parallel streaks. The rest of the submedian spots may be elongated. See Iris.26.p.52 and Vorbrodt’s Schmett.Schweiz. diagram.

ab. parisiensis (Gerhard.Mon.Eur.Schmett.1852.p.17.pl.32.fig.4.)

= arcuata Courvoisier.(nee.Weymer).Mitt.Schweiz.Ent.Ges.1903.XI.p.21.
= arcuata Wheeler.Butts.Switz.1903.p.32.

Underside of the forewings with the lowest submedian spot united with a basal spot to form an arc. The ab. arcuata of Weymer was for icarus but the name is used by many authors for coridon, Courvoisier and Wheeler both use it for coridon. Esper figures a similar aberration, which he calls tiphys, which looks extremely like a coridon but Tutt, Verity and other authors have decided that it belongs to bellargus.

ab. partimalbodescens (Bright & Leeds.Mon.Corid.1938.p.52.)

A contrasting difference in the colour of the marginal lunules on the upper or underside of the female, one or more being white, the rest normal.

ab. partimauronulla (Bright & Leeds.Mon.Corid.1938.p.53.)

Female. On the upperside one or more of the marginal lunules absent, but others present on either side of the absent ones.

ab. partimflavescens (Bright & Leeds.Mon.Corid.1938.pp.30 and 52.)

A contrasting difference in colour of the marginal lunules, one or more being straw-coloured, the rest normal. Occurs on both upper and underside of the female and on the underside of the male.

ab. partimfurvescens (Bright & Leeds.Mon.Corid.1938.p.53.)

Female upper or underside. A contrasting difference in colour of the marginal lunules, one or more being brownish, the rest normal.

ab. partimfuscofimbriata (Bright & Leeds.Mon.Corid.1938.p.22.)

On the forewings the fringe is dusky brown but with a slight intervention of white, or if three of the darker chequerings connect across the width of the fringe. A typical Leeds description.

ab. partimlutescens (Bright & Leeds.Mon.Corid.1938.p.52.)

A contrasting difference in colour of the marginal lunules, one or more being pale orange, the rest orange. Female upper or underside. Not worthy of a name.

ab. partimrufescens (Bright & Leeds.Mon.Corid.1938.p.53.)

A contrasting difference in the colour of the marginal lunules on the upper or underside of the female, one or more being vermilion or dark red, the rest normal.

ab. partimsuffescens (Bright & Leeds.Mon.Corid.1938.p.70.)

Female. Underside with the marginal lunules showing a contrasting difference, one or more being slaty, greyish or even black but the rest reddish.

ab. partimtransformis (Bright & Leeds.Mon.Corid.1938.p.12.)

Pathological examples with a wing or wings showing thinly-scaled, pallid or bleached spots, streaks or areas.

ab. parvipuncta (Courvoisier.Z.Wiss.Ins.1907.3.p.74.)

= parvipuncta Robel.Berge’s.Schmett.1910.p.72.

Underside of both fore and hindwings with the spots very small.

ab. peraurantia. (Tutt.Brit.Lep.1910.XI.pp.12 and 14.)

Female. A row of well-developed orange lunules in the margin of the hindwings and beginning to appear on the forewings from the anal angle upwards. Transitional to aurantia. Leeds calmly states that this name should not have been used for female uppersides as the type form has a partial series of orange lunules on fore and hindwings. Poda did not describe the female. Leeds makes this form and name apply only to undersides, which is nonsense.

ab. pertithonus (Tutt.Brit.Lep.1910.XI.p.15.)

Female. All wings blue scaled as in tithonus (syngrapha) but showing definite orange marginal lunules on the hindwings and faint ones on the forewings.

ab. plumbescens (Tutt.Brit.Lep.1910.XI.p.20.)

Male. Leaden coloured ground. Apparently an extreme form of the ‘suffusa’ series.

ab. polonus [hybrid] (Zeller.Stett.Ent.Z.1845.6.p.351.)

Said to be a hybrid between bellargus and coridon. Brighter ground colour than the normal coridon male, intermediate between the two species. The forewings show almost lineal borders, edged inwardly on the blue with black spots. The hindwings marginal black spots are very distinct and well circled with whitish. The forewings look more like bellargus and the hindwings much nearer coridon. Another form is dull in ground colour with a strong sheen of violet or purple-blue, the outer borders a mere line, the spotting small and indistinct.

ab. postalba (Bright & Leeds.Mon.Corid.1938.p.64.)

Female. The underside with the hindwings white, the forewings with little or non.

ab. postalbescens (Bright & Leeds.Mon.Corid.1938.pp.27 and 65.)

Male underside form with the forewings of the male contrastingly darker than the extensively white hindwings. The female forewings show no white but the hindwings banded with white from the margin to or beyond the submedian spots.

ab. postalbocincta (Bright & Leeds.Mon.Corid.1938.pp.14 and 55.)

Male. On the hindwings only, the discoidal spot is black almost or quite surrounded by whitish. Female similar.

ab. postalbomaculae (Bright & Leeds.Mon.Corid.1938.p.57.)

Female. On the upperside of the hindwings a row of white spots situated midway between the outer border and the discoidal spot.

ab. postalbonigrofimbriata (Bright & Leeds.Mon.Corid.1938.p.59.)

Female. On the hindwings the fringes are edged for at least a considerable distance with darker colour.

ab. postalbopuncta (Bright & Leeds.Mon.Corid.1938.pp.14 and 55.)

Male. On the hindwings only, the discoidal spot is whitish devoid of a black centre. Female similar.

ab. postaurantiaextensa (Bright & Leeds.Mon.Corid.1938.p.53.)

Female. On the hindwings one or more of the orange marginal lunules unusually long inwardly, wedge-shaped, sometimes extending into the discoidal area. Applies also to the underside.

ab. postaurodifferentiae (Bright & Leeds.Mon.Corid.1938.p.54.)

Female. Hindwings showing marginal orange lunules different in size or number on opposite wings asymmetrically.

ab. postbielongata (Bright & Leeds.Mon.Corid.1938.p.32.)

Underside of the hindwings with two of the basal spots elongated.

ab. postbrunnescens (Bright & Leeds.Mon.Corid.1938.p.27.pl.4.f.16.)

Male. The underside of the hindwings of a darker shade of brown or fawn without a bright sandy appearance with none or very little grey shading. Forewings white marked or white, pale grey, or pale brown.

ab. postcaerucincta (Bright & Leeds.Mon.Corid.1938.p.55.)

Female. Showing the discoidal spot of the hindwings ringed with blue.

ab. postcaerumaculae (Bright & Leeds.Mon.Corid.1938.p.57.)

Female. On the upperside of the hindwings a row of blue spots situated midway between the outer border and the discoidal spot.

ab. postcaerupuncta (Bright & Leeds.Mon.Corid.1938.p.55.)

ab. postcentrijuncta (Bright & Leeds.Mon.Corid.1938.p.38.)

Underside of the hindwings with one of the basal spots or a streak from the base extending into the discoidal white patch, or connecting with the discoidal spot if present.

ab. postcrassilunulata (Bright & Leeds.Mon.Corid.1938.p.54.)

Female upper or underside. Hindwings with the discoidal spot larger.

ab. postcrassipuncta (Bright & Leeds.Mon.Corid.1938.p.34.)

Underside of the hindwings with the spots much enlarged.

ab. postdecrescens (Bright & Leeds.Mon.Corid.1938.p.21.)

ab. postdigitata (Bright & Leeds.Mon.Corid.1938.p.41.)

Underside of the hindwings with a basal spot united with the discoidal spot and then branching into two streaks, which connect with the submedian spots.

ab. postdiscoidalisnulla (Bright & Leeds.Mon.Corid.1938.p.31.)

Underside of the hindwings with the discoidal spots absent, even the whitish blotch.

ab. postdiscojuncta (Bright & Leeds.Mon.Corid.1938.p.39.)

ab. postexteratransversa (Bright & Leeds.Mon.Corid.1938.p.42.)

Underside of the hindwings with at least three of the small marginal dots connected by a transverse line.

ab. postextrema (Bright & Leeds.Mon.Corid.1938.p.42.)

Underside of the hindwings with a basal spot connected with the discoidal spot and continued on through the submedian spots to reach the marginal chevrons in one or more streaks.

ab. postfowleri (Bright & Leeds.Mon.Corid.1938.p.19.)

Hindwings with one or more of the marginal discs devoid of a central black point. The forewings normal, not showing the fowleri character. Upper and underside.

ab. postfuscofimbriata (Bright & Leeds.Mon.Corid.1938.p.22.)

On the hindwings the fringes are uniformly dusky brown. Forewings normal.

ab. postglomerata (Bright & Leeds.Mon.Corid.1938.p.34.)

Underside of the hindwings with the submedian and basal spots drawn in towards the discoidal, forming a sort of semicircle around it.

ab. postgriseofimbriata (Bright & Leeds.Mon.Corid.1938.p.22.)

On the hindwings the fringes are grey. Forewings normal.

ab. postica-obsoleta (Tutt.Brit.Lep.1910.XI.p.18.)

= cinnus Gerhard.(nom.preoc.Hubner).Vers.Mon.Eur.Schmett.1853.pl.32.f.2b.
= semi-cinnus Cabeau.Lamb.1923.23.p.49.
= postcaeca Bright & Leeds.Mon.Corid.1938.p.43.

Underside of the hindwings with all spots absent except the discoidal. Forewings normal.

ab. postico-extensa (Tutt.Brit.Lep.1910.XI.p.39.pl.2.f.12.)

= postdiscoelongata Bright & Leeds.Mon.Corid.1938.p.40.

Underside of the hindwings with some or all of the submedian spots elongated into streaks pointing towards the discoidal but not reaching it.

ab. postico-juncta (Tutt.Brit.Lep.1910.XI.p.18.)

= postjuncta Bright & Leeds.Mon.Corid.1938.p.40.

Underside of the hindwings with small extra black spots dribbled into thin incomplete streaks.

ab. postimpuncta (Bright & Leeds.Mon.Corid.1938.p.32.)

Underside of the hindwings with the basal spots absent.

ab. postincrescens (Bright & Leeds.Mon.Corid.1938.p.22.)

On the hindwings the outer border shows more divisions than normal. Forewings normal.

ab. postlunacuspidis [a] (Bright & Leeds.Mon.Corid.1938.pp.31 and 54.)

The hindwings with the discoidal spot showing a point or points extending outwards. First described as a male underside but occurs on both upper and underside of the female.

ab. postlunacuspidis [b] (Bright & Leeds.Mon.Corid.1938.p.31.)

Underside of the hindwings with the black discoidal spot extended from its centre and ending in a point or two points. Forewing discoidals normal. Also described as an upperside form.

ab. postlunulata [a] (Bright & Leeds.Mon.Corid.1938.p.14.)

Male. A distinct blackish discoidal spot on the hindwings only. Leeds applies this also to the underside on which the spots must be not merely faded but blackish and distinct.

ab. postlunulata [b] (Bright & Leeds.Mon.Corid.1938.p.31.)

Underside of the hindwings with a blackish discoidal marking. Also described as an upperside form.

ab. postmaculae (Bright & Leeds.Mon.Corid.1938.p.57.)

Female. On the upperside of the hindwings a row of spots situated between the outer border and the discoidal spot, white and blue mixed, not of one definite colour.

ab. postmixtaelongata (Bright & Leeds.Mon.Corid.1938.p.33.)

Underside of the hindwings with elongated basal spots but different in number on the one side from those of the other.

ab. postobsoleta (Bright & Leeds.Mon.Corid.1938.p.43.)

On the underside of the hindwings one or more of the submedian spots are absent, or two or three basal spots, or some of each. This is not the same as postico-obsoleta Tutt.

ab. postobsoletissima (Bright & Leeds.Mon.Corid.1938.p.44.)

Underside of the hindwings with all spots, including the discoidal, absent. Forewings normal.

ab. postparvipuncta (Bright & Leeds.Mon.Corid.1938.p.33.)

Underside of the hindwings with the basal and submedian spots very small.

ab. postpluripuncta (Bright & Leeds.Mon.Corid.1938.p.35.)

Underside of the hindwings with extra black spots in normally unspotted areas.

ab. postpulla (Bright & Leeds.Mon.Corid.1938.pp.28 and 67.)

= nigrescens Verity.(nom.nov.pro.atrescens.Verity).Farf.Diurn.It.1943.2.p.309.
= atrescens Verity.(nom.preoc.Tutt.1910).Ent.Rec.1926.38.p.124.

Male and female. The underside of the hindwings dark slaty to black. Forewings grey. Verity’s atrescens was a female. His second attempt at a name was also unfortunate since it was also preoccupied, this time by Leeds.

ab. postquadrielongata (Bright & Leeds.Mon.Corid.1938.p.33.)

Underside of the hindwings with four of the basal spots elongated.

ab. postradiata (Bright & Leeds.Mon.Corid.1938.p.41.)

Underside of the hindwings with one or more of the submedian spots lengthened outwardly and connecting with a marginal chevron in a streak or streaks.

ab. postradiosa (Bright & Leeds.Mon.Corid.1938.p.48.)

ab. postsagittata (Bright & Leeds.Mon.Corid.1938.p.40.)

Underside of the hindwings with the marginal chevrons elongated into wedges or pointed streaks, which extend towards the submedian spots.

ab. postsemipluripuncta (Bright & Leeds.Mon.Corid.1938.p.35.)

The underside of the hindwings showing blind white discs in normally unspotted areas.

ab. poststriata (Bright & Leeds.Mon.Corid.1938.p.41.)

Underside of the hindwings with a basal spot united via the discoidal spot with a submedian spot.

ab. posttransiens (Bright & Leeds.Mon.Corid.1938.p.40.)

Underside of the hindwings with three of the basal spots elongated.

ab. postultradiscreta (Bright & Leeds.Mon.Corid.1938.p.34.)

Underside of the hindwings with the discoidal spot thrown outwards towards the margin. Sometimes the basal spots also follow this trend. Tutt’s discreta forms apply only to the submedian spots but Leeds uses the name for the discoidal spots.

ab. postultrafulvescens (Bright & Leeds.Mon.Corid.1938.p.66.)

Female. Underside of the hindwings slaty, coffee or chocolate tinted extending to almost black but with a dark sandy or reddish diffusion. This reddish is nearly of a brick red. What colour this form really is, only Leeds can tell.

ab. postunielongata (Bright & Leeds.Mon.Corid.1938.p.32.)

Underside of the hindwings with one of the basal spots elongated.

ab. postvacua (Bright & Leeds.Mon.Corid.1938.p.44.)

Underside of the hindwings with all markings, spots and marginal chevrons, absent.

ab. pulla [a] (Bright & Leeds.Mon.Corid.1938.pp.11, 28 and 67.)

Male. The upperside with the ground colour slate or slaty extending to just short of black. The next description on p.28 of Leeds Mon. is an underside form of the male with the forewings unicolorous, perhaps a trifle less dark than the hindwings which are the colour of slate or even darker, occasionally with a slight tint of brown. The description of the female underside on p.67 says the forewings are grey slaty or up to black and may only show the slightest tint of brown, sometimes they are partly white. The hindwings dark slaty, blackish or black. Whether or not these various forms belong to the upperside male with slaty ground colour is a debateable point. The colour of the upperside is governed by light on the scale formation.

ab. pulla [b] (Bright & Leeds.Mon.Corid.1938.pp.28 and 67.)

Male and female. The underside of the forewings unicolorous, a trifle less dark than the hindwings which are as dark or even darker than the colour of slate, sometimes with a slight tint of brown. Since Leeds has used this name for upperside of the male with slate coloured wings this underside form must be slaty on the upperside also. Examples which are slaty on the underside only are not pulla.

ab. punctata (Tutt.Brit.Butts.1896.p.167.,fig.Brit.Lep.XI.pl.1.f.8.)

= limbomaculata Schultz.Jahres.Wien.Ent.Ver.(1905)1906.16.p.77.
= punctata-margino Bright & Leeds.Mon.Corid.1938.p.17.
= ultrapunctata Bright & Leeds.Mon.Corid.1938.p.17.
= ultrapunctata-margino Bright & Leeds.Mon.Corid.1938.p.18.

Male. Bright silvery blue with spotted margins. Tutt enlarges on this description in his Brit.Lep.XI.p.11 and says these spots are well developed marginal ocellated spots. There is no necessity for Leeds names, they are all covered by Tutt’s punctata.

ab. punctata-pallidula (Tutt.Brit.Lep.1910.XI.p.11.)

Male. Forewings with well-developed marginal ocelli but the ground colour pale silvery blue. Hardly worthy of a separate name, punctata was bright silvery-blue.

ab. punctata-viridescens (Tutt.Brit.Lep.1910.XI.p.12.)

Male. Pale silvery greenish-blue ground with well-developed marginal ocellated spots. Forewing only.

ab. quadrielongata (Bright & Leeds.Mon.Corid.1938.p.32.)

Underside of the forewings with four elongated basal spots or streaks.

ab. quadrilunulata (Tutt.Brit.Lep.1910.XI.p.10.)

Male. A discoidal point showing on all four wings.

ab. quadripuncta (Courvoisier.Mitt.Schweiz.Ent.Ges.1903.XI.p.22.)

Underside of the forewings with four basal spots.

ab. quadrisuavis (Bright & Leeds.Mon.Corid.1938.p.21.)

Male. Four yellowish spots on the inner side of the black border spots of the hindwings.

ab. quinquepuncta (Bright & Leeds.Mon.Corid.1938.p.32.)

Underside of the forewings with five basal spots. Leeds gives Courvoisier as author which is not so.

ab. quinquesuavis (Bright & Leeds.Mon.Corid.1938.p.21.)

Male. Five yellowish spots on the inner side of the black border spots of the hindwings.

ab. quintaerratica (Bright & Leeds.Mon.Corid.1938.p.35.)

Underside of the forewings with the fifth submedian spot much enlarged or elongated.

ab. radiata (Bright & Leeds.Mon.Corid.1938.p.41.)

Underside of both fore and hindwings with the submedian spots lengthened outwardly to reach the marginal chevrons in streaks or rays. Verity and Leeds both give Courvoisier as the author though there appears to be no mention of a ‘radiata’ under the species coridon. See Iris.26.p.53 and the Courvoisier diagram in Verbrodt’s Schmett der Schweiz.

ab. radioalbolunulata (Tutt.Brit.Lep.1910.XI.p.15.pl.1.f.15.)

Female. As in albolunulata but the forewings showing blue at the base and the hindwings blue from the base to the margins.

ab. radioaurantia (Tutt.Brit.Lep.1910.XI.p.15.)

Female. As in aurantia with orange marginal lunules well represented on both fore and hindwings but the forewings with blue at the base and the hindwings blue from the base to the marginal area.

ab. radioperaurantia (Tutt.Brit.Lep.1910.XI.p.15.)

Female. As in peraurantia Tutt but the forewings blue at the base and the hindwings blue from the base to the marginal area.

ab. radiosa (Gaschet.Bull.Soc.Ent.Fr.Ser.5.1877.7.p.LXIII.)

Female. On the hindwings the veins are blue with the interneural spaces blackish. Forewings similar but less striking.

ab. radiosubalbolunulata (Tutt.Brit.Lep.1910.XI.p.15.)

Female. As in subalbolunulata but the forewings with blue at the base and the hindwings blue from the base to the margins.

ab. radiosubaurantia (Tutt.Brit.Lep.1910.XI.p.15.pl.1.f.17.)

Female. As in subaurantia with orange lunules well marked on the hindwings only, but with the forewings blue at the base and the hindwings blue from base to the marginal area.

ab. radiosubocellata (Tutt.Brit.Lep.1910.XI.p.14.)

Female. As in subocellata with the marginal spots faintly edged with greyish but the forewings blue at the base and the hindwings blue from base to the margins.

ab. retrojuncta (Bright & Leeds.(nec Courvoisier).Mon.Corid.1938.p.37.)

Underside of the hindwings the fourth basal spot is united with the marginal chevrons in a streak. Leeds credits Courvoisier with the authorship but has given the description of a much rarer form than Courvoisier’s retrojuncta which was merely a synonym of basijuncta Tutt and not at all rare. Leeds name for this form cannot stand however since it is preoccupied by Courvoisier’s.

ab. roystonensis [intersex] (Pickett.Ent.Rec.1914.26.p.275.)

Female with male scaling on one or more wings in a peppered manner but never reaching the full scaling of the male. The wing affected is usually smaller.

ab. rufescens [a] (Tutt.Brit.Lep.1910.XI.p.19.)

Female. The marginal lunules bright vermilion-red instead of orange. Tutt was describing underside forms when naming rufescens but it occurs on the upperside and may be used for such examples.

ab. rufescens [b] (Tutt.Brit.Lep.1910.XI.p.19.)

Underside with the marginal lunules of the hindwings vermilion-red.

ab. sagittata (Bright & Leeds.Mon.Corid.1938.p.41.)

Underside of both fore and hindwings with the marginal chevrons elongated into wedges or pointed streaks and extending towards the submedian spots. Courvoisier did not describe this form under coridon.

ab. samsoni (Verity.Ent.Rec.1926.32.p.140.)

Male. Brilliant electric blue, like the less violet bellargus and captured at the early date of June, the time for the first generation of bellargus. Apart from this it is nothing but a coridon similar to the Asiatic race caucasica. The underside like coridon. See full description for more detail. Verity says ‘there is no reason to suspect a hybrid except for the epoch of emergence’.

ab. semi-aurantia (Tutt.Brit.Butts.1896.p.167.)

= semiaurantiaca Lambillion.Pap.Belg.1902.p.240

Female. Indistinct orange marginal lunules edged internally with paler, but with blue scaling at the base of the wings, which is lacking in aurantia.

ab. semi-i-nigrum (Bright & Leeds.Mon.Corid.1938.p.35.)

Underside of the forewings with the lowest submedian spot almost uniting with a basal spot in a straight line, broken however in the middle.

ab. semi-i-nigrum-arcuata (Bright & Leeds.Mon.Corid.1938.p.36.)

Underside of the forewings with the lowest submedian spots united with basals to form two lines, the upper one an interrupted straight line, the lower one a complete arc.

ab. semi-i-nigrum-i-nigrum (Bright & Leeds.Mon.Corid.1938.p.36.)

Underside of the forewings with the lowest submedian spots united with basals to form two lines, the upper one an interrupted straight line, the lower one a complete straight line.

ab. semi-i-nigrum-semiarcuata (Bright & Leeds.Mon.Corid.1938.p.36.)

Underside of the forewings with the lowest submedian spots united with basals to form two lines, the upper one an interrupted straight line, the lower one an interrupted arc.

ab. semialbescens (Bright & Leeds.Mon.Corid.1938.p.65.)

Female. Underside of the forewings showing any form of white. Hindwings with a white-lined costa and patches or streaks of white.

ab. semialbofimbriata (Tutt.Brit.Lep.1910.XI.p.11.)

= postalbofimbriata Bright & Leeds.Mon.Corid.1938.p.22.

On the hindwings the fringe shows no chequerings or divisions. Forewings normal.

ab. semiarcuata (Courvoisier.Mitt.Schweiz.Ent.Ges.1903.XI.p.20.)

= semiarcuata Tutt.Brit.Lep.1910.XI.p.18.

Underside of the forewings with the lowest submedian attempting to unite with a basal spot forming an incomplete arc.

ab. semiarcuata-arcuata (Bright & Leeds.Mon.Corid.1938.p.37.)

Underside of the forewings the lowest submedian spots unite with basals to form two stripes or lines, the upper one an interrupted arc, the lower one a complete arc.

ab. semiarcuata-i-nigrum (Bright & Leeds.Mon.Corid.1938.p.37.)

Underside of the forewings with the lowest submedian spots united with basal spots to form a double line, the upper one an interrupted arc, the lower one a straight line.

ab. semiarcuata-semi-i-nigrum (Bright & Leeds.Mon.Corid.1938.p.37.)

Underside of the forewings with the lowest submedian spots united with basal spots to form two lines, the upper one an interrupted arc, the lower one an interrupted straight line.

ab. semibasijuncta (Bright & Leeds.Mon.Corid.1938.p.37.)

Underside of the hindwings with the third basal spot almost uniting with the lowest submedian, or each elongated towards the other.

ab. semibasijuncta-basijuncta (Bright & Leeds.Mon.Corid.1938.p.37.)

Underside of the hindwings with the third basal spot united with the lowest submedian in a streak, and another interrupted streak from the same basal spot to the next submedian.

ab. semibasijuncta-retrojuncta (Bright & Leeds.Mon.Corid.1938.p.37.)

Underside of the hindwings with the third basal spot and the lowest submedian spot elongated towards each other but not uniting and the fourth basal spot united with the last marginal chevron in a streak.

ab. semibi-i-nigrum (Bright & Leeds.Mon.Corid.1938.p.36.)

Underside of the forewings the lowest submedian spots attempting to unite with basal spots to form two incomplete interrupted straight lines composed of spots, streaks, or both, but failing to make complete lines as in ab. bi-i-nigrum.

ab. semibiarcuata (Bright & Leeds.Mon.Corid.1938.p.36.)

Underside of the forewings with the lowest submedian spots almost united with a basal or basals to form two incomplete arcs, one directly above the other.

ab. semibibasijuncta (Bright & Leeds.Mon.Corid.1938.p.38.)

Underside of the hindwings with two interrupted streaks in the same area as basijuncta Tutt, an attempted union of basal and submedian spots, sometimes as far as the marginal chevrons.

ab. semibrunnea (Milliere.Icon.1859.1.p.84.pl.4.f.3.)

Female. On the upperside of the forewings the veins on the outer margins are silvery blue, almost whitish, with the interneural spaces blue. The base to beyond the discoidal is brown. Hindwings brown in the basal and central areas except for silvery blue veins, becoming blue at the margins up to the chevrons, similar to the forewings. This form is opposite to syngrapha with which it has been confused by Seitz, Wheeler etc., the blue being on the outer margins instead of at the base.

ab. semicincta (Tutt.Brit.Lep.1910.XI.p.10.)

Male. The marginal black spots of the hindwings edged only on their external half with whitish.

ab. semicostajuncta (Bright & Leeds.Mon.Corid.1938.p.37.)

Underside of the hindwings with the first basal spot and topmost submedian spot attempting to unite but just failing to do so.

ab. semifowleri (Bright & Leeds.Mon.Corid.1938.p.18.)

= antifowleri Bright & Leeds.(underside).Mon.Corid.1938.p.84.

Forewings with one or two blind discs or squares in the border which is narrow. Hindwings devoid of circles or discs in the border. Leeds quite wrongly says that the semifowleri forms are produced when there are no blind squares on the hindwings, the type of fowleri had no blind squares on the hindwings. These semi forms therefore can only stand on the reduced number of blind squares on the forewings.

ab. semifowleri-margino (Bright & Leeds.Mon.Corid.1938.p.18.)

Forewings with one or two blind discs in the marginal border which is broad. Hindwings normal.

ab. semilimbojuncta (Bright & Leeds.Mon.Corid.1938.p.39.)

Underside of the hindwings with the topmost submedian spot elongated outwards and attempting to connect with a marginal chevron.

ab. seminigra (Preissecker.Verh.Zool.-bot.Ges.Wien.1906.62.p.87.)

Male. On the forewings a broad marginal band on the outer border and extending along the costa from the apex down to the discoidal point. More extreme than Tutt’s marginata.

ab. semipluripuncta (Bright & Leeds.Mon.Corid.1938.p.35.)

The underside with both fore and hindwings showing blind white discs in normally unspotted areas, these discs having no black pupils or dots.

ab. semiretrojuncta (Bright & Leeds.Mon.Corid.1938.p.37.)

Underside of the hindwings with the fourth basal spot elongated towards the marginal chevrons but not reaching them. It is unfortunate that Leeds links this form with retrojuncta Courvoisier since he is completely wrong in his description of retrojuncta itself. This is a synonym of basijuncta Tutt and has the third basal spot united with the lowest (twin-spot) submedian, not with the marginal chevrons at all.

ab. semisyngrapha (Tutt.Brit.Butts.1896.p.167.)

= infrasemisyngrapha Bright & Leeds.Mon.Corid.1938.p.48.

Female. The forewings blue to the discoidal point from the base, hindwings blue from the base to the outer margin. Leeds form is too insignificant to separate.

ab. semisyngrapha-aurantia (Tutt.Brit.Lep.1920.XI.p.15.)

Female. Forewings blue from base to the discoidal point, hindwings blue from base to outer margin. Orange marginal lunules on both fore and hindwings.

ab. semisyngrapha-peraurantia (Tutt.Brit.Lep.1910.XI.p.15.pl.1.f.18.)

Female. As in semisyngrapha-aurantia but with orange lunules on the hindwings and only beginning to appear on the forewings.

ab. semisyngrapha-subaurantia (Tutt.Brit.Lep.1910.XI.p.15.)

Female. As in semisyngrapha but with orange marginal lunules on the hindwings only.

ab. semitribasijuncta (Bright & Leeds.Mon.Corid.1938.p.38.)

Underside of the hindwings with three parallel lines in the ‘basijuncta’ area, one may reach the marginal chevrons. These lines are interrupted, not complete as in tribasijuncta.

ab. semivirgatus (Bright & Leeds.Mon.Corid.1938.p.52.)

Female. Three or more orange marginal lunules united on the hindwings. Forewings with traces of orange lunules but not so prominent as in virgatus.

ab. semivirgularia (Bright & Leeds.Mon.Corid.1938.p.39.)

Underside of the forewings with one or both of the submedian twin-spots elongated outwards and attempting to connect with marginal chevrons.

ab. sessilis (Tutt.Brit.Lep.1910.XI.p.10.)

Male. The marginal black spots of the hindwings completely linked with the margin there being no external edging of whitish between. Leeds includes female.

ab. signata (Bright & Leeds.Mon.Corid.1938.p.17.)

Male. The marginal spots of the forewings upperside with whitish markings on either side but not completely encircling them as in indistincta Tutt. A completely unnecessary name, covered by Tutt’s indistincta. Tutt obviously called the form indistincta because the whitish circles were not complete.

ab. sinecaerulescens (Bright & Leeds.Mon.Corid.1938.p.63.)

Female. The underside of the hindwings devoid of basal scales. Tutt was not the author of this form in coridon, only in icarus.

ab. sinistro-obsoleta (Tutt.Brit.Lep.1910.XI.pp.18 and 37.)

Underside with the left wings obsolete, the right wings normal.

ab. striata (Tutt.Brit.Butts.1896.p.167.,Brit.Lep.1910.XI.p.41.)

= striata Stefanelli.Bull.Soc.Ent.It.1904.36.p.5.
= digitata Courvoisier.Iris.1912.26.p.53.
= antidigitata Bright & Leeds.Mon.Corid.1938.p.41.

Tutt first very briefly described striata in Brit.Butts.1896.p.167 as having the spots of the underside more or less united into streaks. The full description is given in Brit.Lep.1910.XI.p.41 restricting striata to characters described. The description reads ‘The second, third and forth submedian spots of the forewings united with the discoidal spot, one of the basal streaks similarly joined thereto, whilst the lower basal and lower submedian are extended and approach the biarcuate form. It is to this form in which the submedian and basal spots unite with the discoidal that we now restrict the name striata’. The hindwings are not mentioned so are presumed normal. Leeds description is wrong.

ab. suavis (Schultz.Ent.Z.1904.18.p.93.)

Male. On the hindwings there are reddish-yellow spots on the inner edge of the usual black marginal spots, generally in cells 2 and 3. Leeds wrongly includes Tutt’s female form flavescens in this group but is has no relationship with suavis.

ab. subalbolunulata (Tutt.Brit.Lep.1910.XI.pp.12 and 14.)

Female. On the hindwings only whitish secondary crescents surmounting the black border edging the inner side of the orange lunules. The ground colour with no blue scaling. Leeds says that this is albolunulata ignoring Tutt’s description.

ab. subaurantia (Tutt.Brit.Lep.1910.XI.p.12.pl.1.f.12.)

Female. The marginal spots of the hindwings inwardly marked with fulvous lunules the tint well-developed. On the forewings however a greyish outline suffices to mark the marginal ocelli. The wings brown with no blue scaling. Leeds includes this as an underside form but since most specimens show orange lunules there is not much point.

ab. subcaeruleolunulata (Tutt.Brit.Lep.1910.XI.p.29.)

= caerulunulata Bright & Leeds.Mon.Corid.1938.p.56.

Female. A complete row of blue lunules on the hindwings.

ab. subelongata (Bright & Leeds.Mon.Corid.1938.p.33.)

Underside of the hindwings with an extra basal spot near the inner margin, just above the lowest of the four normal ones, this spot being elongated.

ab. subfusca (Tutt.Brit.Lep.1910.XI.p.10.)

Male. On the forewing upperside whitish spots in the black border largely lost, only noticeable by their grey inner edges. Bright silvery blue ground colour.

ab. subfusca-pallidula (Tutt.Brit.Lep.1910.XI.p.11.)

Male. Pale silvery-blue ground with wide blackish border, the spots in it showing only their grey inner edges. Forewing only.

ab. subfusca-viridescens (Tutt.Brit.Lep.1910.XI.p12.)

Male. Pale silvery greenish-blue ground with wide blackish border, the spots in it only showing their grey inner edges. Forewing only.

ab. subocellata (Tutt.Brit.Lep.1910.XI.pp.12 and 14.)

Female. The first stage of the appearance of the marginal spotting becoming edged externally with whitish or greyish, forming an inconspicuous marging. The wings brown with no blue scaling.

ab. subradiosa (Tutt.Brit.Lep.1910.XI.p.12 and 14.pl.1.f.14.)

= radio Bright & Leeds.Mon.Corid.1938.p.47.

Female. Forewings blue at the base only, but the hindwings blue from the base to as far as the discoidal point, or beyond, suffusing the basal and discal areas. There are no orange marginal lunules.

ab. subsuffusa (Tutt.Brit.Lep.1910.XI.p.20.pl.1.f.4.)

= margotransformis Bright & Leeds.Mon.Corid.1938.p.12.

Pathological examples with the marginal areas thinly scaled on the forewings from the apex down to the anal angle. This area is roughly triangular, almost the same as in ab. marginata Tutt but suffusedly semi-transparent, sometimes drab or brownish.

ab. suffescens (Bright & Leeds.Mon.Corid.1938.p.70.)

Female. Underside with the marginal lunules greyish, slaty, or blackish.

ab. suffusa (Tutt.Brit.Butts.1896.p.167.,fig.Brit.Lep.XI.pl.1.f.6.)

= transparens Courvoiser.Mitt.Schweiz.Ent.Ges.1903.Xi.p.23.

Male. Of a suffused brownish-grey hue, the scaling thin with the spots of the underside showing through.

ab. supraalbocrenata (Bright & Leeds.Mon.Corid.1938.p.16.)

Male. The forewings more strongly marked than in ab. ultraalbocrenata, the white radiating between the veins the central rays reaching the discoidal spot or beyond. The female is described on p.56 as similar, but this is nothing more than an extreme form of albolunulata Tutt.

ab. supramelaina (Bright & Leeds.Mon.Corid.1938.p.12.pl.1.f.20 and 23.)

Male. Dense huge black border extension on both fore and hindwings but ceasing before the base is reached.

ab. syngrapha-inframarginata (Bright & Leeds.Mon.Corid.1938.p.48.)

Female. Of the tithonus (syngrapha) form but with a very broad outer border, 3mm or more in width at the centre.

ab. tarasina (Cabeau.Rev.Mens.Soc.Ent.Nam.1920.20.p.19.)

On the underside of the forewings all the ocelli except the marginal ones, are confluent into one large black area as in the Hesperid, Pyrgus malvae ab. taras, which has this same area white on a black ground. In this form, tarasina, the joined up spotting is black and very distinct on a white ground.

ab. tithonus (Meigen.Eur.Schmett.1830.p.30.pl.47.f.2.)

= syngrapha Keferstein.Stett.Ent.Z.1851.12.p.308.
= mariscolore Gerhard.Vers.Mon.Eur.Schmett.1852.p.17.pl.32.f.3a and 3b.
= cyanogyna Schawerda.Ent.Rundsch.1938.55.p.469.

Female. The upperside of all wings thickly sprinkled with blue scales with a central black lunule on each wing, the forewings only brown on the costa and outer margin. The most used name for this form is syngrapha but under the new rules [of precedence] regarding infra-specific forms, the name tithonus can be used as the oldest, despite the fact that Hubner had used it for another species (Samml.Eur.Schmett.1803.p.55.pl.108.fig.555). In consequence, some of Tutt’s forms are based on the name syngrapha and others on tithonus. Schawerda’s cyanogyna appears to be a rather darker blue form of syngrapha which he says could be taken for bellargus ab. ceronus.

ab. torgniensis (Haverkampf.Ann.Soc.Ent.Belg.1906.1.p.157.)

= lunulata Lange.Iris.1919.33.p.23.
= lunulata Bright & Leeds.Mon.Corid.1938.p.14.

Male. On the forewings a distinct discoidal spot.

ab. transformis (Bright & Leeds.Mon.Corid.1938.pp.13 and 51.)

Pathological examples with one, two or three wings mistily pallid, bleached, or differing from the remaining wing or wings.

ab. transiens (Bright & Leeds.Mon.Corid.1938.p.40.)

Underside of both fore and hindwings with the submedian spots erratic in shape, either wedges or short elongations, not necessarily all of them. Tutt was not the author of this form in coridon.

ab. transinaequalis (Bright & Leeds.Mon.Corid.1938.p.63.)

Female. Streaks, patches or sections similar to inaequalis but whitish in colour instead of blue, occasionally greenish.

ab. transversa (Bright & Leeds.Mon.Corid.1938.p.42.)

Underside of fore and hindwings with two or more of the submedian spots connected transversely forming a downwards union in the form of a line or chain. Leeds gives Courvoisier as the author but Courvoisier’s ‘formae transversae’ was a group name, not to be applied to a single aberration.

ab. tri-i-nigrum (Bright & Leeds.Mon.Corid.1938.p.36.)

Underside of the forewings with three lines or arcs or streaks caused through the union of submedian spots with basals. The two lower ones approximate to bi-i-nigrum or biarcuata, the upper one as in centriquinta merely an elongated submedian.

ab. tribasijuncta (Bright & Leeds.Mon.Corid.1938.p.38.)

Underside of the hindwings with three parallel complete lines in the ‘basijuncta’ area, one of which may reach the marginal chevrons.

ab. trielongata (Bright & Leeds.Mon.Corid.1938.p.32.)

Underside of the forewings with three elongated spots or streaks at the base.

ab. tripuncta (Courvoisier.Mitt.Schweiz.Ent.Ges.1903.XI.p.22.)

Underside of the forewings with three basal spots.

ab. trisuavis (Bright & Leeds.Mon.Corid.1938.p.21.)

Male. Three yellowish spots on the inner side of the black border spots of the hindwings. Covered by suavis Schultz and quite unnecessary.

ab. typica (Tutt.Brit.Lep.1910.XI.p.34.)

Applies only to syngrapha forms. A discoidal point on all wings as opposed to ab. lunulata Tutt which has a point only on the forewings. Since this is the typical syngrapha the name is nonsensical and should not be used.

ab. ultraalbesco (Bright & Leeds.Mon.Corid.1938.p.15.p.5.f.4.)

Male. On the hindwings upperside the upper costal border is more than half replaced by white or whitish. The underside similar. Occurs also on upper and underside of female.

ab. ultraalbocrenata (Bright & Leeds.Mon.Corid.1938.p.16.female on p.56.)

Male. On the forewings whitish marks extend over the ground colour from the black border for a considerable distance inwards. Sometimes there are only two or three of these streaks, rarely the white extends almost as a level whitish inner band, intruding broadly on the blue and only cut by the veins. Female. Leeds includes a female form under this name with a most ridiculous description, which says it must have numbers 44 to 57 included in it. These ‘numbers’ are forms with various coloured discoidal spots and various coloured crescents or wedges on the hindwing borders. In addition, it has well-scaled white or whitish situated on the ground colour of the forewings, mostly between the veins. This latter part presumably is to match the white marks of Tutt’s albocrenata which, in the female, Tutt has already named albolunulata. It would be best to ignore Leeds female description.

ab. ultraalbonigrofimbriata (Bright & Leeds.Mon.Corid.1938.p.59.)
