Dreak ; punctnratiou of abdomen rather dense, segments 2 to 8 with transverse 

 carina before apex, tenth segment hardly one-third longer than broad ; hooks of 



cremaster pale. Food-plant : Asimina triloba and other species of Asimina, 



rarely Ei'tcaceae and Lauraceae. 



A seasonally variable species. Two principal forms : a variable spring form 

 emerging from hibernated pupae, and a summer form emerging from pupae which 

 have not wintered. As the size and markings of the specimens appear to depend 

 on the temperature of the period critical for the chrysalis, the late spring specimens 

 approach the summer and autumn specimens, and the early Spring individuals from 

 the most southern districts of the range of the species resemble in certain characters 

 the late spring specimens of the more northern districts. The time of appearance 

 in spring varies also with the latitude of the locality,
