M. Obcrthiir suggests that this may l)e a mehmic form of his P. lialisca 

 (= Aporia procris, Leech), lie does not mention the sex of A. lhamo, but I 

 am inclined to think that it may prove to be the female of A. procris, of which 

 I have only received male examples In coloration it differs from male 

 A. procris in the same manner that the female oi A. (hii'idis does from the 

 male of that species. 



Aporia potanini. 



Aporia martineti, (^Ijerthiir, ? ^ , Ali)liei aky, Rom. sur Lep. v. p. 95^ pi. v. fig. 1 (188U). 

 Aporia potanini, Alpherali y, loc. cit. ]). 90. 



Alpheraky considered that two female specimens of Aporia taken in 

 July 1885, in the valley of the Hei-ho, province of Kan-sou, were probably 

 the then unknown female of Aporia martineti, Oberth., but reserved to 

 hhnself the name potanini in the event of their proving to be distinct; and 

 this is now found to be the case. 



In his remarks on these specimens, Alpheraky states that the neuration of 

 the secondaries, the shape of the discoidal cell, which is broader and shorter 

 than in A. hippia, Brem., also the comparative brevity of nerve eight, inclined 

 him to think that they were females of ^. martineti; at the same time he 

 considered that they agreed better in many characters with the females of 

 A. crataecfi, with which they are identical in the neuration and shape of wings, 

 but differ, however, in the dark grey coloration of both surfaces of the wings, 

 and in having an ochreous yellow patch at the base of the secondaries on the 

 under surface ; moreover, there is no trace of the yellow coloration between 

 the nerves so characteristic of A. martineti, A. hippia, and its variety dieti. 



Mesapia peloria.

" Upperside white, slightly tinged with yellow, the body and the base of the wings very black. 



Anterior wing with the costal margin and the nervures broadly brown. Posterior ^^iug with 



nerviires black, the nervules tinted with lilac, the end of each marked with a large spot of 



brown upon the outer margin. 

 " Underside the same, except that the posterior wing is yellow, the nervules broadly brown, and 



that the base is marked with orange. 

 " Expanse inch. Chinese Tartary." {Heiuiison, I. c.)
