Arctiidae 
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.
