The difficulty which exists in understanding the forms of P. napi 

 found in America has not been overcome, though for many years 

 many good observers were working on the spot. Mr. Edwards's 

 admirable monograph in ' PapiHo ' for June 1881 has made clear 

 one thing to my mind ; and that is, that there can be no greater 

 mistake than to decide hastily in such intricate questions as these. 

 The East-Asiatic forms of P. napi are puzzling in the extreme ; and as 

 we at present know little or nothing of their distribution, seasons, 

 and larval states, I can only say that I believe the synonyms cpioted 

 above apply to what I should consider a form of P. napi common in 

 Japan and Amurland, but not hitherto seen from China. P. aglaope 

 seems analogous to the European form P. bryonice, considered, as I 

 think justly, by Mr. Edwards as the parent stock of this species.

I have examined the types of P. claripennis and P. sordida, both 

 of which are in Pryer's Chinese collection. 



In P. claripennis from Shanghai the spots do not show through the 

 upperside of fore wing, but I see no characters of note by which to 

 separate it. P. sordida, from the Snowy Valley near Ningpo, seems 

 intermediate between P. rapce and P. yliciria, having the spots on 

 outer margin of hind wing partly obsolete, and those on fore wing 

 smaller than in Shanghai specimens oi P . gliciria, which nearly corre- 

 spond with Himalayan ones, though not quite so heavily marked. 



I have not seen P. gliciria from Japan or Amurland. 



P. DAPLIDICE, Linn. Syst. Nat. x. p. 468. 



I have two specimens of this from China, locality uncertain, but 

 probably Shanghai. I have not seen it from Japan, though De I'Orza 

 includes it in his list. Bremer mentions it as found at Pekin and 

 on the Amur. He also includes the spring form P. bellidice, Ochs., 

 under the name of 



Anthocharis belemida, var. orientalis, Br. Lep. Ost-Sib. p. 8, 



which was found on the Onon by Radde, though not seen by Dr. 

 Staudinger from Amurland.

This distinct species, which seems most nearly allied to the Cali. 

 fornian A. lanceolata, Bdl., is found in Northern and Central Japan 

 and at Shanghai, the latter specimens agreeing perfectly with
