no Lloyd's natural history. 



The under side is yellow, with a black discal spot on the fore- 

 wings, centred with white, beyond which is a reddish transverse 

 streak, and a transverse ferruginous streak on the hind-wings. 



The larva feeds on a number of plants, including Indian 

 corn, Sassafras, Dogwort, and Poplar. It is somewhat stout 

 and fleshy, light green, with a reddish-brown and white stripe 

 on the sides, extending from the fourth segment to the 

 extremity of the body. Each segment has five or six tufts of 

 green prickles, terminated by minute black points which prick 

 the hand if touched, causing severe smarting. The pupa is 

 dark brown, approaching black, and is enclosed in a cocoon 

 between leaves. 



Abbot found the larva to spin up on September 27, and the 

 first moths appeared on the wing on May 17, and others 

 continued to emerge at different times till August 15 follow- 

 ing. When young, the larvae feed in large companies, but 

 afterwards become solitary.

This is another American genus of moderate-sized species; 

 but, unlike the last, the species are more numerous in North 

 than in South America, especially in the Western States. The 

 body is downy, and the wings are moderately long and broad, 

 and rounded at the tips. They are opaque, and there is a 

 crescent-shaped spot in the middle of each.
