Clouded Yellow 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. aegra (Verity.Rhop.Pal.1909.p.270.)

On the upper and underside some blackish marks or spots. These may or may not be stains. In any case the form would seem to be pathological and not worthy of a name.

ab. alba [helice form] (Lempke.Lamb.1933.33.p.39.)

= leucos Berger.Lamb.1936.36.p.200.

The ground colour pure or dead white.

ab. albissima [helice form] (Ragusa.Elenco dei Lep.Sic.1916.p.20.)

= oberthuri Braun.Amat.Pap.1923.1.p.177.
= somnambula Bryk.Ent.Tidskr.1923.44.p.109.
= pallida Stauder.(nom.preoc.Tutt).Z.Wiss.Ins.Biol.1920.16.p.222.

Form of helice with the discoidal spot on the upperside of the hindwings white instead of orange.

ab. angustior (Cockerell.Entom.1889.22.p.148.,fig.Entom.11.p.52.)

The wings narrower and longer in proportion than usual.

ab. atrofasciata (Rocci.Atti.Soc.Ligust.Sc.Nat.1920.30.p.25.,

= enervata Kitt.Z.Ost.Ent.Ver.1924.9.p.17.
= nigrofasciata (male) Manon.Proc.Verb.Soc.Linn.Bord.1925.77.p.147.
= diloui (male) Manon.Proc.Verb.Soc.Linn.Bord.1927.p.27.

Male form with no yellow veins showing in the black marginal bands.

ab. aubuissoni [helice form] (Caradja.Iris.1893.6.p.171.)

= flavida Ksienchopolsky.Trav.Soc.Rech.Volhynie.1911.8.p.29.
= auriflua Berger.Lamb.1936.36.p.200.

The ground colour yellowish-orange, intermediate between the type and helice. The hindwings dark dusted with a large orange discoidal.

ab. basisuffusa (Lempke.(

= suffusa Tutt.(nom.preoc.Cockerell.1889).Brit.Butts.1896.p.259.

Female. The base of the forewings strongly suffused with blackish.

ab. berioi (Dufrane.Bull.Soc.Ent.Belg.1947.83.p.73.)

Female. On the forewings the black discoidal spot is surmounted by another little black spot. The hindwings also have three little black points, characteristic of ab. punctifera Braun.

ab. berthina [helice form] (

On the upperside the marginal spots are of a clear greenish tint, contrasting with the whitish colour of the rest of the wings.

ab. bicolorata (Mezger.Lamb.1932.32.p.210.)

On the forewings the ground colour between the discoidal spot and the margin is yellow but the basal half orange. On the hindwings between the discoidal spot and the margin are four yellow spots encroaching on the grey-green ground colour.

ab. bimaculata (Rocci.Atti.Soc.Ligust.Sc.Nat.1920.30.p.26.,

On the hindwings the discoidal spot is separated into two distinct spots on both upper and underside.

ab. bipupillata (

On the hindwings the discoidal spot is separated into two distinct spots on the upperside only. On the underside it is normal.

ab. breignetti (Manon.Proc.Verb.Soc.Linn.Bord.1927.79.pp.26 and 27.)

Male. The forewings the colour of light chrome or more the colour of mastic, the hindwings of normal colour.

ab. brunnea (Tutt.Brit. Butts.1896.p.259.)

The marginal bands brown.

ab. caerulea [helice form] (Verity.Entom.1904.37.p.54.)

= caerulea Dragoni-Rabenhorst.Ent.Z.1912.26.p.115.

Form of helice with the underside of a most lovely pale sky-blue, replacing the green parts. Upperside of the whitish helice form.

ab. chrysotheme (

= chrysothemeformis Verity.Ent.Rec.1919.31.p.87.

Stephens thought his specimen to be the continental species of that name [Colias chrysotheme, Lesser Clouded Yellow], the author of which was Esper. It was a male of smaller size and paler than C. edusa [syn. croceus]. Other differences, according to Stephens, were the rotundity of the hind margin of the forewings, the dissimilar form of the marginal band and expanded duskiness at the base of the wings, especially the hindwings, etc. The coloured figure seems to be no more than a slightly smaller than usual croceus. Verity’s chrysothemeformis was identical with chrysotheme Esper, except for the patch of androconial scales in the male; chrysotheme does not have these. The form can hardly be classed as an aberration. It is best not to use this name.

ab. cincta (Le

On the upperside of the hindwings the discoidal spot is surrounded by black.

ab. cinerascens (Rowland-Brown.Entom.1921.54.p.156.)

A form of the male in which the black markings tend to albinism and are very pale grey. Cited by Oberthür in Lep.Comp.3.p.173 and figured by Verity in This is confusing as the figure by Verity was named ab. passa and Verity rightly described it as having the bands pale reddish-brown. Rowland-Brown now names the same figure cinerascens possibly because it has patches of pale greyish-brown, hence his description of tending towards albinism. Actually it is merely a pathological specimen. If cinerascens is used at all it is for specimens for small areas of pallid or misty coloration, which do not deserve a name at all.

ab. completa (Lempke.Lamb.1933.33.p.83.)

Female. On both fore and hindwings the black marginal border is divided by a continuous chain of united yellow spots. The inner black band of the hindwings is as wide as the outer one; the pattern thus matches the forewings.

ab. crassesignata (Kitt.Z.Ost.Ent.Ver.1924.9.p.16.)

Female. The spots in the black marginal band of the forewings pale and large, standing out prominently, the discoidal spot also large.

ab. cremonae (Verity.Rhop.Pal.1911.p.358.,

= cremonae Bang-Haas.Iris.1912.26.p.103.
= tergestina Stauder.Boll.Adriat.1913.p.149.
= oberthuri Pionneau.(nom.preoc.Braun)
= henriettae Pionneau.(
= pallida Manon.Proc.Verb.Soc.Linn.Bord.1926.77.p.147.
= perpallida Manon.Proc.Verb.Soc.Linn.Bord.1927.79.p.26.
= helicinoides Braun.Lamb.1930.30.p.9.

These are all forms of the male in which the ground colour is of a decided yellow instead of the normal orange. They vary in tint from sulphur-yellow to greenish-yellow but since it is almost impossible to know exactly what shade the author meant they are included under the oldest name ab. cremonae Verity, which was a male with the ground colour greenish-yellow. Bang-Haas gave the same name and colour. Stauder’s tergestina was sulphur-yellow, sometimes citron-yellow (green tinted) in both the males and females. Manon’s pallida and perpallida were males of this same colour. As regards henriettae = oberthuri, Pionneau described it from the specimen mentioned by Oberthür in, which was a male, very pale yellow. However, Pionneau sent a co-type to Lempke (see Lamb.33.p.62), which was very little lighter than typical croceus and in Lempke’s opinion not worthy of a name. Pionneau’s original description, the one given by Oberthür, must however be taken very pale yellow and his selection of such a co-type seems strange.

ab. dawsoni (Kruger.Soc.Ent.1900.14.p.155.)

On the forewings the base is suffused with deep black extending outwards in the shape of three fan-like streaks or smears, almost to the middle of the cell.

ab. deannulata (Rocci.Atti.Soc.Ligust.Sc.Nat.1920.30.p.26.)

On the underside of the hindwings the outer line or shade, which encloses the silver of the discoidal spot, is absent.

ab. decurtata (Kitt.Z.Ost.Ent.Ver.1924.9.p.16.)

Female. The marginal band of the forewings abbreviated and very little black marking on the hindwings, thus the pale markings are more extensive.

ab. dentata (Caruel.Rev.Fr.Lep.1955.15.p.31.)

The black marginal band of the hindwings shows on its inner side in the interneura spaces, teeth that are directed towards the base, resulting from a deep infiltration of the yellow veins into the band.

ab. derennei (

The figure shows a female with the veins in the black border of the forewings outlined in yellow especially towards the apex. Sometimes the discoidal spot is very large. The hindwings normal. Some authors make this the same as ab. hyerensis but since the hindwings are normal this cannot be so.

ab. divisa (Rocci.Atti.Soc.Ligust.Sc.Nat.1920.30.p.25.)

= marginata Braun.Amat.Pap.1923.1.p.178.

Female. The yellow spots in the black marginal band of the forewings joined together into a continuous band, dividing the black border almost into two parts.

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

The forewings both of helice colouring but the hindwings of normal orange croceus. Also, specimens with the left wings croceus orange colouring and the right wings helice colour. These two specimens are in the Rothschild-Cockayne-Kettlewell collection. However, the name cannot stand as both are fakes, beautifully executed and stuck together so that the joints cannot be seen, but fall apart when relaxed in moisture.

ab. earinica (Oberthür.Lep.Comp.1909.3.p.175.)

Female. The black border of the forewings powdered with yellow at the apex. Oberthür does not state the colour of the veins, which in ab. hyerensis Strand, are outlined prominently in yellow.

ab. electra (

= nigrofasciata Maurer.Jahresb.Wien.Ent.Ver.1909.p.31.,nom.preoc.Verity.1908.
= semiobsoleta Rocci.Atti.Soc.Ligust.Sc.Nat.1920.30.p.25.
= posteropseudomas Kraut.Ent.Z.1929.43.p.84.,

Female. The spots in the margin of the hindwings absent.

ab. faillae (Stefanelli.Bull.Soc.Ent.It.1900.32.p.178.)

Male form with the veins in the marginal bands of all wings strongly yellow.

ab. fischeri (Braun.Lamb.1928.28.p.117.,

On the underside of the forewings the discoidal spot is ocellated or pupilled.

ab. flammea (Kitt.Z.Ost.Ent.Ver.1924.9.p.18.)

= rutilans Manon.Proc.Verb.Soc.Linn.Bord.1926.77.p.146.

The ground colour rich fiery orange-yellow.

ab. flavomaculata [helice form] (Braun.Lamb.1928.28.p.117.)

= pallida Grüber.Ent.Z.1929.43.p.21.,nom.preoc.Tutt.

Form of helice with the discoidal spot of the upperside of the hindwings light yellow instead of orange.

ab. fulvosignata (Rocci.Atti.Soc.Ligust.Sc.Nat.1920.30.p.24.)

= saturatior Kitt.Z.Ost.Ent.Ver.1924.9.p.16.

Female. The spots in the black marginal band of the forewings are fulvous to orange, not paler than the ground colour.

ab. geisleri (Bryk.Ent.Tidskr.1923.44.p.109.,

= lacrimans Stauder.Soc.Ent.1925.49.p.6.

On the hindwings underside the discoidal spot is large and drawn out into points towards the outer margin.

ab. grisandroconiata (Lempke.Tijdschr.Ent.1954.97.p.311.)

On the hindwings the androconial spot at the base is grey.

ab. helena (Herrich-Schaffer.Eur.Schmett.(Syst.Bearb.),descript.vol.6.p.22.)

The figure shows a male with the submarginal band of the hindwings very much narrowed and with a row of pale orange spots replacing the part of the band which is missing i.e. the inner side, and this can be traced by feeble outlining of the interneural oval spots which are paler orange than the rest of the wing. Treated by some authors as a synonym of the type form but, by the figure, a most unusual aberration.

ab. helicina [helice form] (Oberthür.Bull.Soc.Ent.Fr.1880.p.145.)

= xanthina Berger.Lamb.1936.36.p.200.

The ground colour pale yellow with a bright saffron or rosy glaze.

ab. helicoides (

The forewings of helice colour but the hindwings or normal orange croceus. Presumably a genuine somatic mosaic.

ab. hyerensis (Strand.Soc.Ent.1918.33.p.27.,

Named from the figure in Verity’s Rhop.Pal. which shows a striking insect with three distinct characters. The apex of the forewings is suffused with yellow on the black marginal band and the veins are outlined in yellow. On the hindwings, the black border is almost completely replaced by yellow, only a small portion of black remaining near the apex on the inner side of the yellow spots. The result is an insect much more yellow in the marginal areas than the normal female.

ab. infracaerulescens (

The underside of a cold bluish-grey, an extreme form of infraviridis Verity and transitional to caerulea Verity.

ab. infralutea (

The underside pure yellow, more or less rich.

ab. infraviridis (Verity.Farf.Diurn.It.1947.3.p.280.)

The underside of a decided green with a trace of blue. More frequent in females.

ab. internodimidiata (Rocci.Atti.Soc.Ligust.Sc.Nat.1920.30.p.25.)

Female. On the hindwings the yellow spots in the border are so enlarged as to obliterate the inner part of the black band.

ab. irregulata (Dufrane.Bull.Soc.Ent.Fr.1947.83.p.73.)

Male. On the forewings the black border, instead of being sharp and regular, is prolonged into the disc in the interval 4 by strong black powdering. On the hindwing it is prolonged in the same way in the interval 6.

ab. latemarginata (Lempke.Lamb.1933.33.p.86.)

Female. The marginal border much wider than normal, almost reaching the discoidal spot.

ab. lucifer (Richard.Lamb.1946.46.p.92.)

Melanic. All four wings brown-black with the exception of the androconial patches of the hindwings. There remain some orange scales in the disc of the forewings, in particular on the nervures. Underside of the forewings the median area brown, the apex orange but all patterns effaced. Underside of hindwings normal.

ab. maculata (Lempke.Lamb.1933.33.p.80.)

Male. The marginal band showing some spots as in the female.

ab. magnipuncta (Lempke.Lamb.1933.33.p.86.)

On the upperside of the forewings the discoidal spot is very large.

ab. magnomaculata (Lempke.Tijdschr.Ent.1954.97.p.314.)

On the underside of the hindwings the two silver spots coalesce into one large spot.

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

= major Le Charles.Amat.Pap.1926.3.p.120.
= gigantea Braun.Lamb.1930.30.p.7.

Very large. Specimens over 57mm.

ab. megei (Ecole Bordelaise.Proc.Verb.Soc.Linn.Bord.1925.77.p.22.)

Female. The spots in the black margin of the forewings pale yellow or even white but the ground colour normal orange. It is doubtful if this name can stand since it has no definite author beyond the school, or society, Ecole Bordelaise.

ab. melanitica (

Very similar to ab. suffusa but slightly more extreme. The figure shows the black marginal band of the forewings extended in a very broad stripe occupying the upper third of the wing, obliterating the discoidal spot and almost reaching the base. In addition, there are two further black stripes, much narrower, reaching from the marginal band to the discoidal cell parallel with the inner margin. Hindwings rather devoid of markings apart from a black marginal band, abbreviated in the costal half.

ab. minor (Failla.Nat.Sic.1887.7.p.52.)

= minor Cockerell.Entom.1889.22.p.176.
= pyrenaica Grum-Grshimailo.Hor.Soc.Ent.Ross.1893.27.p.383.

Dwarf forms. Specimens under 57mm.

ab. minoris (Stauder.Z.Wiss.Ins.Biol.1921.16.p.222.)

A small male in which the costa of the forewings is broadly yellow-sulphur to the width of 3mm. The rest of the wing of normal orange colour.

ab. myrmidonides [helice form] (Stauder.Z.Wiss.Ins.Biol.1916.12.p.59.,

= semidivisa Rocci.Atti.Soc.Ligust.Sc.Nat.1920.30.p.25.
= myrmidoniformis Grüber.Ent.Z.1929.43.p.21.f.7.
= marginata Braun.Lamb.1930.30.p.6.

Form of helice, showing in the marginal band of the forewings, eight well-marked yellow spots, which form a continuous light band dividing the black band into two. The spots in the hindwings margin also form a yellow band as in Colias myrmidone [Danube Clouded Yellow].

ab. nervosa (

The veins of the forewings black throughout. The ground colour dusted with black.

ab. niedeicki (Strand.Int.Ent.Z.1909.3.p.78.,

= unimaculata Kitt.Z.Ost.Ent.Ver.1924.9.p.16.

On the underside the discoidal spot of the hindwings is a single ocellus, the small one usually above it being absent or only in the form of a small point without a silver pupil.

ab. nigra [helice form] (Aigner.Ann.Mus.Nat.Hung.1906.[4?].p.448.)

= adoratrix Stauder.Boll.Soc.Adriat.1912.p.149.

Form of helice with the light spots normally seen in the black marginal band absent or almost so as in ab. pseudomas Cockerell of the typical form.

ab. nigrofasciata (Verity.Rhop.Pal.Nov.1908.(not 1909)

= naieri Heinrich.Ent.Z.1930.43.p.295.

On the forewings a black wedge or streak travelling from the black marginal band to the discoidal spot.

ab. nigrofasciata (Braun.(nom.preoc.Verity.1908)

Braun says that this female form is an extension of Verity’s nigrofasciata which was a male and quite distinct from it. The figure shows a black stripe from the apical part of the marginal black band, travelling down the costa to reach the base, uniform in width and just touching the discoidal spot. The base itself is blackened strongly and forms a three pronged fan-like pattern as in ab. dawsoni. Verity’s nigrofasciata merely had the marginal band extended in a streak as far as the discoidal, not reaching the base.

ab. nigrosparsata (Lempke.Tijdschr.Ent.1954.97.p.312.)

The whole orange ground colour of the upperside is finely powdered with black scales.

ab. parvipuncta (Lempke.Tijdschr.Ent.1954.97.p.313.)

On the upperside of the forewings the discoidal spot is distinctly reduced in size, the rest normal.

ab. passa. (

Male with the marginal border pale reddish-brown.

ab. plurimaculata (Mezger.Lamb.1932.32.p.232.)

On the underside of the hindwings the mother-of-pearl (discoidal) spot is surrounded by five other spots, two of which have pearly centres, the three others mere brown dots. The five are all contained in the brown ring, which normally surrounds the main spot.

ab. posticominuta (

The hindwings diminished in size because the external margin is straighter than normal and the tornus has a more acute angle.

ab. posticotersior (

On the upperside of the hindwings the dark dusting is less dense than usual so that the orange shows more like that of the forewings.

ab. pseudomas (Cockerell.Entom.1889.22.p.26.)

= obsoleta Tutt.Brit.Butts.1896.p.259
= paveli Aigner.Rov.Lapok.1901.7.p.30.

Female. The spots in the marginal band absent, or almost so, on both wings.

ab. pullata [helice form] (Heinrich.Ent.Z.1930.43.p.295.)

Form of helice with the light spots I the margin of the hindwings absent.

ab. punctellata (Braun.Lamb.1930.30.p.9.)

The discoidal spot ver small, tending to disappear because it is in part covered with orange scales.

ab. punctifera (Braun.Amat.Pap.1923.1.p.178.)

Female. On the hindwings there are three black spotson the inner side of the yellow spots in the margin. Occurs in both croceus and helice types. These presumably are all that remains of the inner black marginal band.

ab. pupillata (

= albidopupillata
= xanthostigma Stauder.Soc.Ent.1925.40.p.6.
= circumiens Bollow.Seitz.Macrolep.Suppl.1930.1.p.118.

On the forewings the discoidal spot is pupilled with orange on both upper and underside. Reverdin described his form as ‘pupillata’ in the text and ‘albidopupillata’ on his plate. Bollow described his circumiens as having the discoidal spot replaced by a ring which, is the same as having it pupilled with orange.

ab. purpurascens (Cockerell.Entom.1889.22.p.3.,from Entom.11.p.51.)

= micans Fritsch.Int.Ent.Z.1911.5.p.55.
= micans Kiefer.Ent.Rundsch.1913.30.p.321.
= micans Konas.Iris.1914.28.p.17.
= iridescens Constantini.Atti.Soc.Modena.1916.Ser.5.vol.14.p.14.
= riviericola Strand.Arch.Maturg.1927.91.A12.p.281.
= amethystina Braun.Lamb.1930.30.p.9.
= amethystine Frohawk.Vars.Brit.Butts.1938.p.179.

The wings beautifully shot with purple or blue or violet. These various forms all stress this iridescence, either on fore or hindwings or both, so are placed under the one name.

ab. radiata (Nitsche.(nom.preoc.Manon).Z.Ost.Ent.Ver.1932.17.p.85.)

Female. The yellow spots in the black marginal band of the hindwings, drawn out in streaks to the margin.

ab. regressa (

On the upperside the discoidal spot is orange, not black, and therefore like that of the hindwings but smaller. On the underside it is of the normal black.

ab. reisseri (

Melanic. The whole upperside of all wings unicolorous blackish-brown without perceptible markings except an indistinct discal spot and yellowish-green hairs at the base of the forewings.

ab. retracta (Kitt.Z.Ost.Ent.Ver.1924.9.p.17.)

Male. On the forewings the black marginal band extends along the inner margin as far as the middle of the wing or beyond.

ab. retronigra (Delahaye.Suppl.Cat.Lep.Maine-et-Loire.1909.p.9.)

= electra Frohawk.(nom.preoc.Lewin).Vars.Brit.Butts.1938.p.179.

Hindwings almost completely black. Frohawk’s electra had the hindwings densely greenish-black. The forewings normal.

ab. ridicula [helice form] (Alpheraky.Hor.Soc.Ent.Ross.1908.)

= minor Pionneau.(nom.preoc.Failla).Misc.Ent.1930.32.6.p.10.

Dwarf. Very small specimens of helice. See ab. minor Failla for small specimens of the typical form. It seems quite unnecessary to name such specimens again in the helice form.

ab. roseosatura (

The underside very gay owing to the richness and rosy-wine colouring, not only of the head and thorax and contours of the wings, but also the submarginal spots of the hindwings, which normally are rust-coloured.

ab. rubroandroconiata (Obraztsov.Z.Ost.Ent.Ver.1936.21.p.46.)

Male. The androconial spot on the costa of the hindwings is red instead of yellow.

ab. rufomaculata (Lempke.Ent.Ber.(Amst.).1932.8.p.394.)

On the underside of the hindwings the discoidal spot is dusted over with carmine-red. Transitional specimens are tinted lighter red.

ab. schirberi (Oberthü

The true albino and not to be confused with Rowland-Brown’s cinerascens in which he says the markings are very pale grey. The figure by Oberthür shows the marginal band and discoidal spot very pale silvery-grey, absolutely uniform and clear. However, the artist has shown some black scaling at the base of each wing, which an albino should not possess. It is possibly meant as shading.

ab. semidemarginata (Pionneau.Echange.1929.435.p.3.,

On the underside of the hindwings there is no sign of the antemarginal spots. The form is figured in Lamb as demarginata in error.

ab. seriata (Rocci.Atti.Soc.Ligust.Sc.Nat.1920.30.p.25.,

On the underside of the hindwings a complete series of marginal spots, strongly represented.

ab. seriata [helice form] (Pionneau.Echange.1932.47.p.16.,nom.preoc.Rocci.)

Form of helice showing on the underside a complete row of antemarginal spots on the hindwings. Rocci described this form by the same name when occurring in the typical form of croceus.

ab. striata (Geest.Z.Wiss.Ins.Biol.1905.p.379.)

= radiata Manon.Proc.Verb.Soc.Linn.Bord.1926.77.p.149.,

On the forewings the black marginal band is extended in rays or streaks to the middle of the wing. These are also present on the underside.

ab. subobsoleta (Rocci.Atti.Soc.Ligust.1920.p.25.,

= nigrofasciata (female) Manon.Proc.Verb.Soc.Linn.Bord.1925.77.p.147.,nom.preoc.Verity.
= diloui (female) Manon.Proc.Verb.Soc.Linn.Bord.1927.79.p.27.
= obsoleta Grüber.Ent.Z.1929.43.p.21.f.10.,nom.preoc.Tutt.1896.

Female. Some spots in the marginal bands are less prominent than usual. Transitional to ab. pseudomas Cockerell.

ab. subpallida (Manon.Proc.Verb.Soc.Linn.Bord.1926.77.p.147.)

The ground colour a little paler than typical croceus.

ab. subtuscuneata (Galvagni.Verh.zool.-bot.Ges.Wien.1929.79.p.38.f.5.)

On the underside of the hindwings the antemarginal spots are large and wedge-shaped, their points towards the base and merging into the discoidal cell.

ab. subviridis (Manon.Proc.Verb.Soc.Linn.Bord.1927.79.p.27.)

Male with the marginal bands greenish and the ground colour citron-yellow.

ab. suffusa (Cockerell.Entom.1889.22.p.55.,from fig.Entom.11.p.49.)

Melanic. The forewings strongly suffused with black from the marginal band towards the base. Cockerell cites two figures, quite different in appearance, as belonging to this form, the second one in Newman’s Brit.Butts. would appear to be merely stained. His first figure is taken as representing the form and this shows the black marginal band of the forewings extending in tongues towards the base, the main and blackest one stretching from the marginal band, through the discoidal spot, and reaching the base of the wing in the form of a black stripe. Another thinner but complete stripe stretches from the margin to the base. A little above the inner margin and between it and the costal stripe there is a wedge-shaped, less black, tongue which reaches the middle of the wing. The hindwings are more of less usual in appearance, with rather large yellow lunules in the margin.

ab. tenuimarginata (Lempke.Lamb.1933.33.p.86.)

Male with the marginal border only half the normal width.

ab. turbida (Braun.Lamb.1935.35.p.115.)

Female. The yellow spots in the black margins of the forewings are uncertain in their shape and pattern. The figure shows the spots irregular in shape and position but exactly the same on both wings.

ab. unimaculata (Pionneau.Misc.Ent.1925.28.p.57.,nom.preoc.Kitt.1924.)

On the upperside of the hindwings the discoidal spot is single, the small one usually above it is absent. Pionneau does not actually mention upperside or underside but says the form is the same as Colias hyale [Pale Clouded Yellow] ab. unimaculata Tutt and Colias phicomone [Mountain Clouded Yellow] ab. unimaculata Pionneau, both of which are upperside forms. The form when on the underside is named ab. niedeicki Strand.

ab. velata (Ragusa.Nat.Sic.1904.17.p.42.)

Male with the marginal bands covered with filmy green scaling.

ab. zuellichi [helice form] (Nitsche.Z.Ost.Ent.Ver.1932.17.p.85.)

On the underside of the forewings the discoidal spot is completely absent. On the upperside it is represented by a small spot ending in split orange marks. The form was described from a specimen of helice but may well occur among the type form.
