two discal bars, with yellow on the subcostal vein, and 

 the orange patches of the hind wings are larger. 



The eggs are of a delicate light yellow, smooth and 

 round, with the exception of being slightly flattened 

 where they are attached to the leaf. These are depos- 

 ited on the leaves of parsley, celery, parsnips, and other 

 related plants upon which the larvae feed. 



The young larvse are nearly black, with a broad white 

 band across the middle, and another on the hind part of 

 the body ; thickly beset with bristles which arise from 

 little tubercles. The second stage diifers little from the 

 first ; as also the third, though there are bright spots on 

 the body. The fourth stage is a bright green ground

 The tubercles are scarcely perceptible. 



The fifth stage is the mature larva. When full grown
