 Fringfts black. On the under surface the apical area and costa of primaries are tinged with

" Slightly smaller than A. craUvrji. The hind wings are straighter and more oblong. The fore 

 wings have the nervures shaded with black ; beneath, the apices are tinted with yellowish. 

 The hind wings resemble those of crata'gi above, but beneath they have the nervures verv 

 much extended, or shaded with black ; at the base is a patch of bright orange-yeUow.'"

Graeser (Berl. ent. Zeit. 1888, p. 06) states that he found larvse of A. hippia 

 commonly in webs on all the bushes of Berheris sinensis and B. amurensis in 

 the neighbourhood of Vladivostock. He writes : — " The larvte were sent by 

 me in large numbers to Europe during the winters of 1884 and 1885 and 

 were there bred. I need not give any description as the larva can easily be 

 distinguished. Its life-history is exactly like that of A. cratcegi and ..passes 

 the winter in the same way, several together in a close web."

 d'un trait brun noiratre, large surtout au voisinage du bord externe ; les nervures des infe-

 long du bord anterieur ou elles sent un peu empatees de noir.
