PL. XX 



Easily recognized by the figure. One of the larger species, 

 the male having a width of 1.75-2.00, the female of 2.00-2.60 

 inches. Eggs brownish yellow when laid, changing to crim- 

 son, and later to black; deposited in clusters on balmony 

 (Chelone glabra). Hatching in early fall, the little cater- 

 pillars spin a web or tent of silk, where they pass the winter. 

 When spring comes, they scatter, fall to feeding, and after 

 the fifth moult turn into chrysalids, from which the butter- 

 flies soon emerge. 



Found locally in colonies in swampy places, where balmony 

 grows, from Quebec to west of Lake Superior and south to 

 the Carolina mountains.
