This section contains those aberrations that are considered new, and have yet to be formally defined.

britishbutterflyaberrations.co.uk (all aberrations)

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

Male. The ground colour bright silvery blue.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

ab. ultracaeruleo (Bright & Leeds.Mon.Corid.1938.p.9.)

Male. The ground colour dark blue, readily distinguished from the ordinary range of blue.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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

= infraviridescens Bright & Leeds.Mon.Corid.1938.p.10.

Male. The ground colour silvery blue-green. infraviridescens is a superfluous name, the description being “with easily perceptible greenish sheen” and therefore covered by Tutt’s name.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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

Male. The ground colour dark but distinctly greenish.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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

Male. The ground colour darkish but tinted with lavender or dark mauve.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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

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

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.)

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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’.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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

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

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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

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

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

ab. ultramelaina (Bright & Leeds.Mon.Corid.1938.p.12.pl.1.f.17.)

Male. On the forewings the blackish or blackish-grey border extension reaching to or beyond the discoidal cell. Hindwings similar.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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

Male. A discoidal point showing on all four wings.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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

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

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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

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

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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

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

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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

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

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

ab. ultrafowleri (Bright & Leeds.Mon.Corid.1938.p.18.pl.3.f.12.)

All wings with the borders devoid of the central dots in the white squares or discs, the border on its inner side being very narrow or mere shading. Occurs on both upper and underside.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

ab. ultrafowleri-margino (Bright & Leeds.Mon.Corid.1938.p.19.)

Both fore and hindwings with the border discs devoid of their central black points the border of the forewings wide.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

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.

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.

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

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.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

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.

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.

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.

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.

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.

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.

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. 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. 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. 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.

= 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.
