tree and has fed it on the leaves. It comes to its growth in the fall, 

 and curls up and passes the winter in any shelter that it can find, being 

 especially fond of getting under the bark of old trees. In the spring 

 it feeds for a few days upon almost any green thing that presents itself, 

 and then forms a cocoon, casts its prickly skin, and becomes a chrysa- 

 lis. The chrysalis is black, and covered with a beautiful pruinescence. 

 It has a flattened blunt projection at the extremity, armed with a few 

 barbs and brisdes. In a few exceptional cases I have known this 

 species to go through all the transformations and produce the moth in 

 the fall. The chrysalis state lasts but a fortnight. " 



Boisduval states that this species is found in California, as I suppose 

 on the authority of Mr. Lorquin, It has never been the good fortune 

 of myself or fellow Entomologists to verify this observation, though 

 the Wild Sun-Flower is abundant in many localities in the interior 

 of the State, but seldom visited by Entomologists ; and it is possible 

 that the insect may have been taken during some of the rambles of Mr. 

 Lorquin in these localities.
