ICHNEUMON-FLIES OF AMERICA! 1. METOPIINAE 23 



hind tibia beyond basal 0.2 slightly infuscate; legs fulvous except as 

 described otherwise, the front legs of male beyond the trochanters 

 more or less yellowish; clypeal fovea brownish; flagellum light brown 

 below, dark brown above. 



This species is close to the European Chorinaeus cristator (Graven- 

 horst), 1829, differing from cristator in having the mandible a little 

 narrower, the hind coxa ferruginous rather than black, and an average 

 of more numerous and more slender setae on the apex of the penis.

 ("Mt. St. Helena") ; Georgia (Rabun Bald in Rabun Co. and Yonah 

 Mt. in Hall Co.) ; Iowa (Fremont Co. and Kossuth Co.) ; Kansas 

 (Manhattan and Wamego) ; Maine (Bangor and Fort Kent) ; Mary- 

 land (Takoma Park) ; Michigan (Delta Co., East Lansing, Newaygo 

 Co., and George Reserve in Livingston Co.) ; Minnesota (Chisago Co., 

 Fillmore Co., and Houston Co.) ; Missouri (Columbia) ; New Jersey

 ton); Utah (Ogden); Vermont (Woodstock); Virginia ("Barcroft," 

 Dunn Loring, and Mount Elliot in Augusta Co. at 4,473 ft.) ; Wash-

The collection dates are rather evenly distributed in June, July, 

 and August, with a few outside of this range as follows: April 29 in 

 Iowa; May 2 in Riley Co., Kans.; May 3 on Yonah Mt., Ga.; May 7 

 on Mount St. Helena, Calif.; May 16 at Ogden, Utah; May 23 in 

 Fillmore Co. and Houston Co., Minn.; September 3 in Kossuth Co., 

 Iowa; September 4 at Columbia, Mo.; September 6 at Dunn Loring, 

 Va. ; and October 8 at Takoma Park, Md. 



Host records include a number of specimens reared from Ancylis 

 comptana by R. L. Parker and S. A. Summerland at Manhattan, 

 Kans., and at Wamego, Kans., and a female reared from Choristoneura 

 fumiferana at Fort Kent, Maine. 



In the authors' collecting the species has been swept on numerous 

 occasions from the undergrowth of deciduous forests. 



This species occurs in the Transition and Upper Austral zones, 

 rather commonly east of the 100th meridian, sparingly from there to 

 the Pacific Coast. Adults are on the wing throughout the summer.
