II. — Oa Lepidoptera collected in Ja^jan and the Corea hy 

 Mr. W. Wykeham Perry. By ARTHUR G. BuTLER, 

 F.L.S., F.Z.S. 



Mr. W. Wykeham Perry, of H.M.S. ' Iron Duke,' has re- 

 cently sent to the Museum an interesting series of Lepido- 

 ptera (all, with two exce])tions, referable to the Rhopalocera), 

 collected by himself in Hakodate, Yokohama, Kobe, and at 

 Posiette Bay, Corea, during the present year. 



Although the species obtained in Japan exhibit the ordi- 

 nary features of all small collections received from these 

 islands, it is nevertheless interesting to us to obtain, for the 

 first time, specimens from Kobe. But the most important 

 portion of this consignment is the series from Posiette Bay, as 

 giving us some idea of the Lepidopterous fauna of the Corea ; 

 it represents a combination of Japanese, European, and 

 Chinese features which is most instructive. 



If any lepidopterist sliould assert (upon the autliorlty of 

 specimens not received direct from collectors, but purchased 

 through dealers) that the species of Japan and Amur- 

 land are for the most part identical, Mr. Perry's Corean 

 series must present a difficulty to be solved. It contains, in 

 several instances, Japanese and European types of closely 

 allied species side by side ; and those forms which are common 

 in Eastern Siberia seem to be equally abundant in N.E
