ICHNEUMON-FLIES, PART 2! EPHIALTINAE 335 



mesopleurum with rather coarse punctures, on its lower part the 

 punctures rather close (especially in female), separated by less than 

 their diameter, the lower hind part of mesopleurum usually with 

 moderately coarse irregularly oblique wrinkling (especially in female); 

 metapleurum with moderately strong oblique wrinkling and indistinct 

 punctures ; hairs on metapleurum moderately dense, evenly distributed. 



Black. Hairs of head and thorax light gray; palpi fuscous or black; 

 tegula varying from mostly white to entirely black, usually brown or 

 blackish with the base whitish; legs fulvous, the front coxa fuscous 

 or mostly fuscous, front and middle tarsi a little darkened apically, 

 apex of hind tibia often infuscate, and hind tarsus brownish fulvous 

 to blackish; wings of male subhyaline, of female subhyaline to dis- 

 tinctly infuscate. 



This is a species of semidesert areas of the West and Southwest. 

 There are two subspecies distinguished in the female as below. The 

 males of the two subspecies look alike. 



1. Most of front face of hind femur of female with moderately dense hairs, the 

 sockets of the hairs separated by about 0.7 the length of the hairs; range: 

 southern Texas and adjacent Mexico. 



9a. sanguinipes sanguinipes (Cresson; 



Most of front face of hind femur of female with sparse hairs, the sockets of 



the hairs separated by about 2.0 the length of the hairs; range: Rocky 



Mountains to Pacific 9b. sanguinipes erythropus (Viereck) 



9a. Coccygomimus sanguinipes sanguinipes (Cresson) 



Pimpla sanguinipes Cresson, 1872, Trans. Amer. Ent. Soc, vol. 4, p. 165; ? . 

 Type: 9 , Bosque Co., Tex. (Philadelphia). 



Punctures and wrinkling of mesopleurum and metapleurum averag- 

 ing a little denser and finer than in the subspecies erythropus; most 

 of front face of hind femur of female weakly mat and with moderately 

 dense hairs, the bases of the hairs separated by about 0.7 the length 

 of the hairs, the femur smoother and with sparser hairs on the lower 

 0.3 of its front face. 



Wings of both sexes subhyaline or faintly infuscate.
