32. MICROPLITIS MATURUS Weed. 



Microplitis maturus Weed, Trans. Amer. Ent. Soc, vol. 15, 1888, p. 294. 



MicropUtis cincta Ashmead, Canad. Ent, vol. 23, 1891, p. 3. 



Microgaster tuckeri Viekeck, Trans. Kansas Acad. Sci., vol. 19, 1905, p. 274. 



Type.— In the Philadelphia Academy of Sciences ; type of cmcta in 

 the United States National Museum ; type of tuckeri in the University 

 of Kansas. 



New York; Connecticut; Michigan; Kansas; Vermont; Maryland; 

 Illinois ; Florida ; Georgia ; New Jersey ; South Dakota ; Canada. 



Host. — Drasteria, species ; " geometrid' larva." 



Cocoon.—'^ mm. in length ; cylindrical ; not ribbed ; pale brown in 

 color; solitary. 



Tliere can be no question, I believe, that cincta Ashmead and tuckeri 

 Viereck belong here. Notes made by Mr. Gahan on an examination 

 of the type of tuckeri show beyond dispute that this species is 

 maturus. 



In addition to the types of viaturus and cincta I have seen the fol- 

 lowing material: The National Collection contains many specimens 

 from the following localities : Long Island ; Ottawa, Canada ; Stowe, 

 Vermont; Hagerstown, Maryland; Elk Point, South Dakota (reared 

 from a geometrid larva by C. N. Ainslie) ; Algonquin, Illinois; Agri- 

 cultural College, Michigan ; Jacksonville, Florida ; Tift on, Georgia ; 

 Brookings, South Dakota; Anglesea, New Jersey; and Eiley County, 

 Kansas; several specimens, from Hagerstown, Maryland, are re- 

 corded as reared from Drasteria^ species. In the Cornell University 

 Collection there are specimens from Waterville and Ithaca, New 

 York, and Coniston, Ontario, Canada.
