 On the other hand, .Mr. W. II. Edwards has fed 

 belated larva- of Papilio cresphontes on dried leav< 

 prickly ash, softened in water, lit- also fed another belated 

 lo1 with leaves of the hop-tree which had been gathered for 

 two. years. These he soaked overnight, laid between blot- 

 ting-paper, and the larvae ate them readily. Larva- from 

 other countries may 1m- fed in the same manner, the food- 

 plants being sent by mail. Mr. Greene describes what he 

 calls his "larvarium, viz.. a very large l"-\. saj il
