The following two vars., which I have taken, were not supposed to 
occur on our shores :— 
Var. Corydonius. — Perhaps this is the most beautiful form of 
corydon. A lovely violet blue. I have only taken one. This comes 
very near to our Adonis, but is a trifle paler. 
Var. Caucasica. —Ground-colour approaching sky-blue ; much larger 
than type. The largest specimen I ever captured measured If". In 
this variety the cilia are pure white, giving it a striking appearance. 
Females. 
Uppersides. — Corydon. — Dull blackish-brown with indistinct 
marginal spots. 
Ab. Aurantia. —Dull blackish-brown with distinct marginal orange 
spots, edged internally, with paler. 
Ab. Semi-Aurantia. —Dull blackish-brown with distinct marginal 
orange spots, with blue scales at base of wings. 
Ab. Albicincta. With discoidal spots edged with white and streaks 
of blue on hindwings. In this form the shape of the wings is much 
more square than in any other females; it was very much in evidence 
during August, 1900. 
Ab. Semi- Syngrctpha. —With blue base (as far as discoidal spot) to 
the fore wings, blue from the base to the outer margin of hindwings. 
This is a very pretty form, and met with in almost any locality where 
the species varies at all. 
Ab. Synyrapha .—With .wings entirely blue and marginal spots. 
This is an exquisite form, somewhat rare, and occurring mostly where 
the range of variation is greatest. 
Ab. Iuaequalis. — With blue streaks, sometimes varying on opposite 
wings of the same insect ; this is also taken more freely some years 
than others, usually when the shotted forms are more in evidence. 
Unnamed. —There are also two other female forms which do not 
appeal to have been named. Phe first is that lovely golden brown 
form already mentioned, and the second a very pretty form in which 
the discoidal spot in the hindwing is blue, and with a row of blue dots 
above each of the orange spots on the margin. This is near to ab. 
albicincta, only the discoidal spots do not show on the forewings, and 
the ground-colour is much darker and richer. 
Of course, many of these forms overlap, and it is very puzzling to 
know really where to put them. We get a form almost entirely black, 
another quite a warm brown, approaching the golden form ; others 
with small bleached patches, some with discoidal spots enlarged, one 
of which looks like a huge Artaxerxes ; but take them as a whole they 
work out remarkably well. 
Undersides.- Again, there is a wonderful variation of colour from 
whitish to dark grey in the males, and greyish to dark ochreous or 
fuscous in the females ; sometimes a female with very light undersides 
approaching that of the male is found. 
Corydon (Type).—Underside greyish in males, dark ochreous in 
females. 
Ab. Pallida. —Underside white in males, pale ochreous in females. 
Ab. Striata .—With spots on underside, more or less united into 
streaks.
