ICHNEUMON-FLIES, PART 2 1 EPHIALTTNAE 307 



(Bolivar and Cheat Alt. at 2,000 ft. in Randolph Co.) ; and Wisconsin 

 (Madison). 



Dates of collections are rather evenly distributed from spring to 

 early fall. Unusually early and late records are: April 15 at Holliston, 

 Mass.; April 24 at Cold Spring Harbor, Long Island, N. Y.; May 1 

 at Madison, Wis. ; May 5 in Wayne Co., Mich.; May 7 atHagerstown, 

 Md.; September 11 and 13 at Madison, Wis.; September 23 at St. 

 Paul, Minn.; September 26 at Bolivar, W. Va. ; and October 2 in 

 Midland Co., Mich. In our collecting, we have found it in undergrowth 

 of deciduous woods. 



There are two rearing records: d\ reared from Choristoneura 

 fumiferana, Saranac, N. Y., July 27, 1948. d\ reared from Choristo- 

 neura rosaceana, Old Chelsea, Que., July 27, 1937, G. A. Hobbs. 



This is a species of the Alleghanian fauna. Adults occur from 

 spring to early fall. Two species of Choristoneura are recorded 

 as hosts.
