Hdcroc.cra from China, Japan, and Corca, 47 



Common at Nagaliama and Gensau in July, and at 

 Hakodate in August. The specimens in Fryer's collection 

 were from Yokohama and Oiwake, and I have received 

 others from Cliang-yang, Kiukiaiig, and the province of 

 Kwei-chow. 



Staudinger (Rom. sur. Lop., vi, p. 493) merges corvina 

 in livida, but a good series such as that in my collection 

 shows the former to be a generally larger species, the 

 thorax and primaries are more intensely black with 

 purplish reHections, and the secondaries are much more 

 brightly tinted with reddish cupreous.
