ANTHOCHARIS. 477 
" Piqm. Boat-shaped, at first green, but clianging to greyish j-ellow, with clearer stripes. The eggs 
are laid in the summer, and the larva changes to a chrysalis in July, hibernating in this 
state." {Laiuj, I. c.) 
A more extended account of the earlier stages of this species will be found 
in Buckler's ' Larvae Brit. Butt.'

In this form of A. cardamines, which is very common in Western China at 
Ta-chien-lu, Pu-tsu-fong, and Wa-ssu-kow, the male has the secondaries more 
or less suffused with sulphurous, especially about the nerves (I have examples 
similar in this respect from Greece and Asia Minor) ; the dark apex of pri- 
maries is much suffused with orange scales. In the female the apical black 
marking does not extend to the margin (this is also the case in some of my 
Syrian specimens of the same sex). The most important characters of 
thibetann are the broader wings and much longer chequered fringes which 
give the wings the appearance of being scalloped towards apex. 
Graeser (Berl. ent. Zeit. 1888, p. 68) states that A. cardamines is fairly 
plentiful in the neighbourhood of Nicolajefsk, Amurland, in July. The 
females agree with European examples. In the males the black discoidal 
spot is either only faintly indicated or entirely absent ; the orange colour 
extends much further inwards than in European specimens, occupying in 
some individuals almost two thirds of the primaries, and extending along tlie 
inner margin nearly to the middle of the wing. On the under surface the 
space between the orange colour and the base of the wing is much more 
brightly tinged with yellow. I have seen an examj^le of this form in Mr. 
Elwes' collection and it seems to be a transition between A. cardamines and 
A. bambusanim. 
Staudinger (Rom. sur Lep. vi. p. 142) mentions that Radde captured this 
species in the Bm-eja Mountains and that Schrenck met with it from Marinski 
to Nicolajefsk. He states that he has never received specimens from Amur- 
land, and this may account for the fact that he does not make any remarks 
on the difference between Amurland and European examples. 
Alpheraky (Bom. sur Lep. v. p. 100) records a female A. cardam.ines from 
Mongolia, but states that the specimen may possibly be a female of A. 
hambiisartim, Obcrthiir, which he says had hitherto only been recorded from
