Arctiidse 



Genus PARASEMIA Hiibner 



This genus is represented in our fauna by certain varietal 

 forms, which agree in part with those found in the Old World, 

 and in part differ from them. There is only one species in the 

 genus, which has a wide circumpolar distribution, and a score 

 or more of names have been given to mere color varieties. We 

 figure two of the commoner variations. The larva feeds on 

 Planiago and Myosotis.
