" En dessous, ailes superieures blanc jaunatre avec I'apex d'un jaune canari et rempatement iioir 

 nervural, an milieu des ailes, au lieu d'etre au bord extcrieur comme en dessus. Ailes 

 inferieures d'un jaune canari vif avec les nervures noires saillantes sur un filet noir, tres net, 

 pas large et assez vif. L'espace basiluirc 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 quelques individus, est d'un jaune soufre en 

 dessus. J'ai appele cette aberration, qui est coustaute et commune a beauooup de Plerides 

 blanches, stdjihurea. 



•' Le male varie encore ponr le semis d'atomes iioirs qui dans d'autres individus couvre la base ct 

 le milieu des ailes superieures. J'ai appele cette autre aberration, qui est egalement con- 

 stante, /((i?iosa. 



" Dans la femellc los ecailles des ailes sont nioins adherentes que cbez le mfde, et les cinq excmplaircs 

 que jo posscde de ce sexe femelle, out tons un ton luisant resultant de ce que les ailes supe- 

 rieures surtout sont coiurae hyalines. Cependant un semis d'ecailles blanc jaunatre persiste 

 dans le milieu de cbaque espace nervural.

Al])heraky (Rom. sur Lcp. v. p. 90) remarks that after carefully comparing 

 a number of specimens of A. liipina from different localities with typical 

 specimens of hiefi, Oberthiir, from Ta-chien-lu, and also with seventeen 

 examples taken by Potanine in North China and Mongolia, he arrived at the 

 conclusion that hieti was not specifically distinct from hippia but only a Avell- 

 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 ar(^ 

 intermediate between lieti and typical hippia. 



According to Staudinger (Ilom. sur Lep. vi. p. 140), A. hippia is common 

 on the Ussuri and throughout tlie whole of Southern Amurlancl. Staudinger 

 also states that the species is peculiar to Amurland, thus implying that it had 

 never occurred elsewliere. It would seem therefore that lie was not aware of 

 tlic fact that crat(egioides, Lucas, from Pekin, is synonymous with A. liippia. 



Oberthiir (Etud. d'Entom. v. \). 12) records hippia from Askokl. 



The hieti form of this s[)ecies appears to be exceedingly common in ^^'estenl 

 China. The specimens vary considerably in size, some examples are much 

 suffused with blackish about tlie base of the wing {miy. /aniosa, Oberthiir); a 

 few arc tinged with yellow (var. aulphurcrt, Oberthiir) ; a specimen of the 

 latter form is figured (Plate XXXVI. fig. 2^ j ). I have a long series of
