defined, flattened, somewhat spoon-shaped club. The cells of 

 both fore and hind wings are closed. Eggs cone-shaped, flat- 

 tened, and depressed at the top, rounded at the base, ribbed 

 both ways, mostly near the base. Caterpillars dark in color, 

 spiny, with the spines on the first segment the longest; feeding 

 on violets at night, and hiding during the day. Chrysalis 

 angular, adorned with more or less prominent projections, 

 head bifid. 



This large genus has many species. It occurs in both 

 hemispheres. Its metropolis is North America, and we can 

 speak of only a few of the commoner and more conspicuous 

 forms.
