NO. 2349. REVISION OF NEARCTIC APANTELES—MUESEBECK. 545 



As the result of a most careful study of the types of the species 

 listed in the synonymy the writer is of the opinion that they are 

 representatives of scitulus. 



Besides the types of this species and those of the t%YO species 

 placed in synonymy, the National Collection contains specimens 

 as follows: Three specimens from Lincoln, Nebraska, reared by L. 

 Bruner from Acronycta oblinita; a large series from Prince Georges 

 County, Maryland, collected by A. B. Gahan; 4 specimens from 

 Knoxville, Tennessee, collected by G. N. Bentley ; 11 specimens from 

 Brunswick, New Jersey, collector not indicated; 14 specimens bear- 

 ing Bureau of Entomology No. 360a, reared December 7, 1886, from 

 Acronycta ohlivata, locality not indicated; 1 specimen from Law- 

 rence, Kansas, collected by Hugo Kahl; and a large series from 

 Paradise Keys, Florida,. collected by Barber and Schwarz.

habitat. — Very generally distributed over the eastern half of the 

 United States and southern Canada, and occurring as far west as 

 Colorado. Very common. 



Host. — Agrotis c-nigrum Linnaeus; "cutworms." 



Cocoons. — Gregarious, enclosed in a compact ball of whitish silk. 



A careful study of the type material has convinced the writer that 

 the species listed in the synonymy are xylinus Say. 



The National Collection contains, in addition to the type series and 

 the type material of the listed synonyms, numerous series of this 

 species from widely distributed localities. Several of these series 

 are recorded as having been reared from Agrotis c-nigrum; others 

 are labeled as having been reared from cutworms, but so far as known 

 A. c-nigrum is the only identified nost. One lot of specimens bred 

 from A. c-nigrum bears Bureau of Entomology No. 2486°, but is 

 without locality or collector labels. Another series from the same 

 host was reared by H. Severin at Kacine, Wisconsin. The writer 

 has also seen material of this species in the collections of the Iowa, 

 Illinois, Kansas Agricultural Experiment Stations, in the collection 

 of the Gypsy Moth Laboratory, at Melrose Highlands, Massachusetts, 

 and in that of Cornell University.
