THE BUTTERFLIES OF NEW ENGLAND. 



self. Mr. E. T. Cresson has also, with his customary kindness, made 

 certain determinations for me in the Ichneumonidae, and has sent me 

 copies of several of Holmgren's generic descriptions which were not acces- 

 sible to me at Washington. 



The chapter may be appropriately begun with a tabulated arrangement 

 of the hosts from which parasites have been bred, placing opposite to each 

 species of butterfly the parasites which have been reared from it, and the 

 reverse. The main object of the chapter is, of course, to enable the ob- 

 server to identify any parasites which he may have reared from butterfly 

 larvae or pupae, supposing them to have been reared before, and I would 

 advise him first, by examining this list, to ascertain what parasites have 

 been reared from the insect in question, and then to compare the figures 

 and descriptions of these particular species with the specimens he has 

 reared. If he does not in this way satisfy himself, then let him run 

 through the synoptical table of genera and the descriptions of species 

 >vhich follow, and it will not be difficult to ascertain whether his observa- 

 tion is a new one.
