"En dessous, ailes superieurcs blanc jaunatre aveo I'apex d'un jaune canari et rempatemcnt noir 
nei-vural, au milieu des ailes, au lieu d'etre au bord exterieur comme en dessus. Ailes 
infeiieures d'un jauno canari vif avec les nervures noires saillantes sur un filet noir, tres net, 
pas large et assez vif. L'espace basilaire compris dans Tangle nervural est d'un jaune plus 
fence que le fond des ailes. 
" Le male varie pour la couleur des ailes qui, dans quclques individus, est d'un jaune soufre en 
dessus. J'ai appele cetto aberration, qui est constaute et commune a beaucoup de Plerkles 
blanches, sulphurea. 
" Le male varie encore pour le semis d'atomes noirs qui dans d'autres individus couvre la base et 
le milieu des ailes superieures. J'ai appele cette autre aberration, qui est egalement con- 
stante, fumosa. 
" Dans la femollo les ecaillos des ailes sont moins adherentes que chez le male, et les cinq exemplaires 
que je posscde de ce sexe femelle, ont tons ua ton luisant resultant de co que les ailes supe- 
rieures surtout sont comme hyalines. Cependant un semis d'dcaillcs blanc jaunatre persiste 
dans le milieu de chaque espace nervural.

Alpheraky (Eom. sur Lep. v. p. 96) remarks that after carefully comparing 
a number of specimens of A. hippia from cliiFerent localities -with typical 
specimens of bieti, Oberthiir, from Ta-chien-lu, and also with seventeen 
examples taken by Potanine in North China and Mongolia, he arrived at the 
conclusion that Meti was not specifically distinct from hippia but only a well- 
marked form of that species. Potanine's specimens, he says, differ from 
Ta-chien-lu examples in having the wings broader in proportion to their 
length and in the nervures being less heavily bordered with black, and are 
intermediate between Meti and typical hippia. 
According to Staudinger (Rom. sur Lep. vi. p. 140), A. hippia is common 
on the Ussuri and throughout the whole of Southern Amurland. Staudinger 
also states that the species is peculiar to Amurland, thus implying that it had 
never occurred elsewhere. It would seem therefore that he was not aware of 
the fact that cratcegioides, Lucas, from Pekin, is synonymous Avith A. hippia. 
Oberthiir (Etud. d'Entom. v. p. 12) records hippia from Askold. 
The hieli form of this species appears to be exceedingly common in Western 
China. The specimens vary considerably in size, some examples are much 
suffused with blackish about the base of the wing [wax. fumosa, Oberthiir); a 
few are tinged with yellow (var. svlphurea, Oberthiir); a specimen of the 
latter form is figured (Plate XXXVI. fig. 2, c^ ). I have a long series of 
A. hippia from Amurland, and I find there is considerable aberration in the 
neuration of the females, e. g. the second subcostal nervule of secondaries is 
sometimes bifurcate on the outer margin of the wing. In some specimens
