PARASITES REARED FROM EGGS OF GIPSY MOTH. 7 



hairs. General appearance of body more opaque than with the 

 female and metallic reflections less distinct ; leg- coloration identical. 



Described from seven female and four male specimens reared from 

 the eggs of Porthetria dispar, June, Jul}', and August, received from 

 U. Nawa, Gifu, Japan, after whom the species is named. 



Type. — Xo. 12159, U. S. National Museum; Gipsy Moth Labora- 

 tory Nos. 1625, 1020, and 1039. 



This parasite has also been imported from Japan in eggs collected 

 by Professor Kuwana, and seems to follow Schedius in distribution 

 in Japan. It is very much less common, but varies in abundance in 

 different lots of eggs. Unlike Schedius, it has been reared freely 

 from the eggs collected and forwarded during the winter, emerging 

 at various times in the spring and summer. So far as indicated by a 

 considerable number of dissections made bA' ]\Iessrs. Fiske and
