ICHNEUMON-FLIES OF AMERICA: 1. METOPIINAE 27 



these measurements unusually variable; median 0.6 of clypeal margin 

 faintly up-bowed; mandible about 2.1 as long as wide in male, about 

 2.3 as long as wide in female, its upper tooth much larger than its 

 lower tooth, its outer face with very coarse, close punctures; fiagellum 

 with about 29 segments in male, with about 27 segments in female; 

 metapleurum with hairs on its upper 0.2 to 0.3; front spur of middle 

 tibia about 0.71 as long as hind spur; second segment of middle tarsus 

 about 2.2 as long as wide in male, about 1.33 as long as wide in female; 

 second tergite with a longitudinal carina just mesad of spiracle in its 

 basal half; second tergite with indistinct to strong longitudinal 

 wrinkles, with interspersed strong, rather close punctures; apex of 

 penis without setae. 



This species is variable and difficult to define. The separation from 

 the species C. constricius is particularly tenuous and may not be valid. 

 Males might easily be confused with males of C. recurvus. The better 

 recognition characters for C. funebris are the absence or small extent 

 of yellow on the frons, rather wide mouth and long mandible, with 

 heavy close punctures on outer face of mandible and upper mandibular 

 tooth much larger than lower tooth, strong longitudinal wrinkling on 

 second tergite, and in the female a tendency to have a median sub- 

 dorsal facial spot, the area of the clypeal fovea, and the mandible, 

 brownish. We have 10 specimens (all males) which cannot be deter- 

 mined with certainty. They probably all belong under C. funebris, 

 but some may be C. constrictus or represent one or more new species, 

 thus far unrecognized. 



There are four distinguishable subspecies, as treated below. 



Key to the subspecies of Chorinaeus funebris 



1. Hind coxa partly to entirely fulvous, at least its apical 0.2 fulvous; range: 



Canadian to Upper Austral zones east of the Rocky Mountains; also Alberta 



and British Columbia 7a. funebris carinatus (Cresson) 



Hind coxa entirely black or blackish 2 



2. Face with a median blackish wedge or lobe extending from its upper part to 



the clypeal suture, the yellow of the face being thus divided into lateral 

 halves (fig. 178,i); hind femur entirely blackish; range: Colorado and Idaho. 



7d. funebris divisus, new subspecies 



Face without a median blackish area, or with a smaller blackish area that does 



not completely divide the yellow of the face into lateral halves (fig. 178,h); 



hind femur fulvous to fuscous tinged with fulvous 3 



3. Hind femur fuscous tinged with fulvous; range: Europe. 



7b. funebris funebris (Gravenhorst) 



Hind femur clear fulvous, with a faint dorsoapical infuscation; range: Nevada 



to Arizona 7c. funebris ctarus, new subspecies
