Male. The upperside blue-grey or slaty, with a rather narrow border and very small discoidal spots.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
Male. The upperside of the wings so entirely blackened that only a slight blue shimmer is perceptible. Underside normal but slightly darkened.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
Male. The upperside of the forewings white with a slight violet sheen, the nervures and the broad border of a brownish hue. Underside pattern normal except for the two lowest submedian spots which are absent, the ground colour white with the spots little more than mere dots of a yellow-brown tint. Almost certainly a pathological form.

= rufolunulata Reverdin.(in).Tutt.Brit.Lep.1909.X.p.187.May.
= rufolunulata Reverdin.Bull.Soc.Lep.Gen.1909.1.p.373.
Male. On the upperside of the hindwings two orange spots above the black marginal dots. Reverdin’s rufolunulata was a male with tawny lunules surmounting the black marginal dots of the hindwings. Tutt published Reverdin’s description and name before Reverdin’s own article appeared in the Bull.Soc.Lep.Gen. In this, Reverdin, in error, on his plate used the name rufomaculata; pl.10.f1.

= caerulea Courvoisier.(nom.preoc.Tutt).Ent.Z.1910.24.p.93.
= splendida Thompson.Pamphlet.desc.Plebejus argus.1937.p.5.
Female. The upperside entirely pale blue with narrow black margins inside the white fringes and a series of pale whitish marks in place of the orange marginal lunules of the forewings. The hindwings show white edging to the marginal spots. The forewings have the discoidal spot present but it is very faint on the hindwings. Courvoisier’s caerulea had all four wings blue except for a narrow black margin and would seem to be generally the same as Tutt’s. Thompson’s splendida was a female of the subspecies cairnensis entirely suffused with blue. It can be kept separate under cairnensis if desired.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
Female. The upperside of the wings dusted with blue.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
Female. All wings suffused with blue except for a circular patch in the disc of the forewings. Described under subspecies cairnensis and may be separated under that subspecies if desired.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
Female. Blue scaling on the upperside of all four wings but chiefly on the hindwings. On the forewings whitish rays from the margins pointing inwards towards the base and white discoidal spots on both fore and hindwings.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
= pulchrina Thompson.Pamphlet.desc.Plebejus argus.1937.p.5.
= caerucuneata Wykes.Entom.1945.78.p.2.
Female. On the upperside of the hindwings narrow sky-blue wedges or rays set close to the orange marginal lunules, their points reaching almost to the base of the wings. Some blue scales also at the base. Thompson’s pulchrina was described under the subspecies cairnensis and can be separated under that subspecies if desired but the form occurs in all races.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
Female. The upperside of the right side wings brown, the left side blue. This is not an intersex, it is the blue form female combined with the brown form.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
On the upperside one or more streaks of blue scales without androconia, the wings equal in size. Underside and genitalia female.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
Probable homeosis. The figure shows two examples. Fig. 8 shows a patch of underside pattern in the centre of the upperside of each forewing. Fig.11 is similar. By the figures it would seem most unlikely that these are the spots of the underside showing through on the upperside, their white circles are so well defined, yet it is remarkable that two individuals should show the same symmetrical pattern if it is homeosis. The four submedian spots of the forewings underside appear drawn in closely around the discoidal spot and show clearly on the upperside.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
On the upperside the marginal lunules are partially or completely clouded by brown scaling. On the underside the lunules are brown-red instead of orange.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
= parvipuncta Tutt.Brit.Lep.1909.X.p.177.
On the underside the spots are very small. Lempke gives Courvoisier as the author since Courvoisier says it occurs in aegidion [Meisner, 1818], which is a subspecies of argus.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
= crassipuncta Courvoisier.Verh.Nat.Ges.Basel.1910.21.p.158.
On the underside the spots are exceptionally large and sometimes extended.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
The figure shows the underside with extraordinary discoidal spots on all four wings. These are very large, four or five times normal size and roughly triangular, their points towards the margins.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
= transiens Wykes.Entom.1945.78.p.4.

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
On the underside of the forewings the submedian spots extend towards the base in longitudinal streaks. Hindwings with one extended spot on the costa. Very similar to ab. radiata Oberthür, which is slightly more extreme on the hindwings.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
Underside of the forewings with the submedian spots extended towards the base in streaks. Hindwings with the topmost submedian spot connecting with a marginal chevron and the lowest submedian with the lowest basal spot. Very similar to ab. maritimus Stephens.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
= pluripuncta Courvoisier.Iris.1912.26.p.58.
Underside of the forewings with small extra spots appearing in the area between the submedian spots and the discoidal spot.

= costajuncta Courvoisier.Iris.1912.26.p.50.
Underside of the hindwings with the topmost submedian spot united with the upper basal spot to form a streak.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
Several authors include this form under argus because Courvoisier says that it occurs in argus, but at that time he was using aegon for the present species. On the same page however he mentions limbo-retrojuncta as occurring in aegon. The description says the topmost submedian is connected with its opposite marginal chevron to form a short streak.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
Underside of the hindwings with the topmost submedian spot connecting with a marginal chevron, also the third basal spot connecting with its opposite submedian to form two short streaks.

britishbutterflyaberrations.co.uk (all aberrations)
= retrojuncta Courvoisier.Iris.1912.26.p.50.
Underside of the hindwings with the third basal spot connecting with its opposite submedian spot in a streak.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
Underside of the hindwings with the topmost submedian spot connecting with the upper basal spot, also the third basal spot connecting with an opposite submedian spot, two short streaks are thus formed.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
Several authors include this form with this reference but Courvoisier did not include it under this species either as argus or aegon.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
Courvoisier included this form under argus but at that time was using aegon for the present species so if the form occurs in the Silver-studded Blue, Courvoisier is not the author. On the underside of the forewings the third and fourth submedian spots connect with the discoidal spot in two streaks.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
On the underside two or more submedian spots unite transversely.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
Transitional to ab. juncta Tutt. On the underside of the forewings the submedian spots are elongated outwards towards the marginal spots and the marginal spots towards the submedians but just fall short of uniting.

= striata Frohawk.Vars.Brit.Butts.1938.p.116.
On the underside of all four wings the submedian spots connect with the marginal chevrons in bars or short streaks.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
On the underside of all four wings there is a streak from the base to the discoidal spot and the submedian spots are united with the marginal chevrons in bars or short streaks. The discoidal spot is sometimes united with the submedians. This is the most extreme form of striation.
Natural History Museum

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
On the underside of the forewings there are two basal spots.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
On the underside an elongation of the marginal ‘moons’ (chevrons) towards the submedian spots, on the hindwings particularly. Similar, as regards the marginal chevrons to ab. cuneata Tutt, but the submedian spots are present.
Natural History Museum

On the underside there are no metallic or silver scales on the marginal spots.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
Underside differing chiefly in that only one of the hindwings marginal spots shows a silvery kernel. The submedian spots in the figure are very much bowed into a semicircle around the discoidal spot but are no nearer to it.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

Underside of the forewings with the spots six and seven missing. It seems somewhat extraordinary that Tutt should tie his obsoleta to this description.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)

= obsoleta Frohawk.(nom.preoc.Tutt.1909).Vars.Brit.Butts.1938.p.116.
Underside with all the spots, except the discoidals, absent. Both of these names are preoccupied so neither can stand.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
On the underside the ground colour of the wings is black-grey.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
On the underside the normally white parts are clouded over with fawn or greyish suffusion.

Perineural defect. The figure shows no veins, the underside of the forewings with the submedian spots forming a transverse line, completely joined together in the upper part, becoming less joined down towards the inner margin. The marginal black spots are similarly joined together to form a continuous line. Hindwings with the submedian spots joined and forming a strong black transverse line, the marginal spots less strongly joined and not so thick. A black bar or streak in the cell through the uniting of the discoidal spot with a basal spot.
