CHARLES W. HOOKER. 33 



Distribution. — Grand Lake, Newfoundland, to Williams- 

 port, Pa., and Carbondale, 111. 



This species ranges from the lower Boreal at 45** to the 

 lower edge of the Upper Austral at 38^, and possibly into 

 the Lower Austral zones. I have seen specimens taken at 

 Grand Lake, Newfoundland ; Amherst and Cohasset, Mass. ; 

 Connecticut ; Ithaca and New York City, N. Y. ; Williams- 

 port, Pa., and Carbondale, 111. 



Life history and habits, etc. — Little is known of the life his- 

 tory and habits of this species. It has been taken from June 

 2 to September 7, but seems to be most abundant in August 

 and September. Its value as a parasite can not be deter- 

 mined as the list of hosts is very incomplete. The type was 

 " bred from a dark cocoon of one of the larger species of 

 Apatela {Acronycta); the parasitized cocoon was taken in 

 Connecticut."
