OF NORTH AMERICA. 9T 



I do not find any description of the mature larva of ^. Aviericana, 

 but the description of the young quoted above differs materially from 

 that of E. caja, in which the long hairs are rusty and black, instead of 

 white and black. The larva of Euprepia is very similar to that of 

 Epicallia virginalis, (q. v.) E. Americana appears to be confined 

 chiefly to the northern portion of the continent, but in that region 

 to be widely distributed. In California, its most southern range, it is 

 a mountain insect, altitude taking the place of latitude.
