 chrysalis, has the body and front wings of a fleshy-gray, 

 marked and shaded with olive-green, while the hind 

 wings are of a deep rust-color, with a small shade of 

 gray near their inner angle. 



This insect is in northerly regions one-brooded, but 

 towards the south two-brooded, the first worms appear-

 in September and, passing the winter in the chrysalis 

 state, give out the moths the following May. On one 

 occasion we found at South Pass, 111., a worm half 

 grown and still feeding as late as October 20th, a circum- 

 stance which would lead to the belief, that at points 

 where the winters are mild they may even hibernate in

This worm is a most voracious feeder, and a single one 

 will sometimes strip a small vine of its leaves in a few

 leaf, stops at every cluster of fruit, and either from
