BUTTERFLIES COLLECTED BY SURGEON LAMBERT, 

 R.N., AT VLADIMAR BAY, &c, AUGUST, 1897. 



By Henry Charles Lang, M.D., F.E.S., M.R.C.S., &c. 



This small collection came into my hands through Mr. 0. E. 

 Janson in 1900 ; it consists of one hundred and five specimens, 

 collected by Surgeon Lambert at Vladimar Bay, in Russian 

 Tartary, between the dates of August 1st and 9th, 1897, and a 

 few from Port Hamilton, in Corea, on June 16th and 17th of the 

 same year. Owing to the care with which these specimens were 

 labelled, I am able to give the exact dates. He also collected in 

 Japan and China, but at the time of seeing the collection I was 

 not interested in these latter, as I did not then consider that the 

 butterflies of Japan and China should be included in the Palae- 

 arctic Region, though I have now altered my views in this respect 

 as regards Japan. 



Papilionid^:. 



Papilio xuthus, L. — Eight males, one female ; August 5th to 8th, 

 1897. Vladimar Bay. On comparing these with four males and five 

 females from Pryer's collection, taken near Tokio, I find that the 

 Japanese specimens differ as regards the males from those from 

 Vladimar Bay in having the marginal band of the hind wings broader, 

 and reaching to the discoidal cell, just as in P. machaon var. sphyrus. 

 Four of the Japanese females differ in no way from that from the 

 Amur, and the fifth only in being somewhat larger, and in the deeper 

 yellow of the ground colour. 



P. machaon, L. — One female; August 3rd, 1897. Vladimar Bay. 

 Differs in nothing from ordinary large European specimens ; expanse, 

 3^ in. Certainly not to be considered as var. hippocrates. 



P. bianor, Cram. — One female. Port Hamilton, Corea, June 16th, 

 1897. The ordinary typical form. 



P. bianor var. maackii, Men. — Vladimar Bay. Two males, August 

 8th and 9th, 1897; two females, August 9th, 1897. These resemble 

 specimens from Japan. 



Parnassius nomion, Fisch. — Vladimar Bay. Two males, August 

 5th and 6th, 1897 ; three females, August 5th and 9th, 1897. 



PlERID/E. 



Pieris rapce, L. — Vladimar Bay. One female, August 8th, 1897 — 

 usual typical form ; one female, August 8th, 1897 — var. orientalis,
