ICHNEUMON-FLIES OF AMERICA: 1. METOPIINAE 41 



front tentorial arm visible as a short line extending mesad and a very 

 short stub distovertrad from clypeal fovea; eye apparently bare; 

 flagellum with 22 segments; metapleurum with a narrow area of hairs 

 along its entire upper margin, broader at its hind end, narrowed in 

 front; striae of metapleurum moderately fine, reaching forward to 

 0.3 the distance from its front edge; propodeal spiracle very short 

 elliptic, distinctly separated from pleural carina; front spur of middle 

 tibia 0.47 as long as hind spur; second segment of middle tarsus 1.45 

 as long as wide; second abdominal tergite 0.75 as long as wide, with 

 moderate-sized, rather close, longitudinal punctures; sublateral carina 

 of third tergite rather weak, extending 0.3 the length of the tergite. 



Black. Face, clypeus, and mouth parts yellow, the mandible 

 fulvous with the base brown, the face with its upper 0.2 blackish; 

 tegula entirely blackish; extreme apex of femora, basal 0.2 of tibiae, 

 and tibial spurs stramineous; front femur blackish brown, lighter 

 brown apically and in front; front tibia light bown; tarsi and middle 

 and hind tibiae dark brown, the segments usually paler apically ; legs 

 blackish except as described otherwise. 



Type: 9, taken in an area of desert shrub, Leevining, Calif., June

Figures 178,o; 180, e 



Front wing 3.5 to 4.3 mm. long; face about 1.5 as wide as high, its 

 punctures small and sharp, separated by about 0.8 their diameter; 

 face and clypeus in profile weakly convex; clypeal fovea subcircular, 

 without evident marks around it from attachment of front tentorial 

 arm; eye with very short and sparse hairs; flagellum with 26 segments 

 in male, with about 24 segments in female; metapleurum with num- 

 erous hairs along its upper margin, the hah- band very narrow ante- 

 riorly, broader posteriorly; striae of metapleurum rather fine, con- 

 fined to an area near the hind coxal attachment but extending forward 

 just above submetapleural carina; propodeal spiracle elliptic, ad- 

 jacent to pleural carina; front spur of middle tibia about 0.64 as long 

 as hind spur; second segment of middle tarsus about 2.05 as long as 

 wide in male, about 1.85 as long as wide in female; second tergite 0.74 

 as long as wide in male, about 0.70 as long as wide in female, with 

 medium sized, longitudinal, moderately close punctures; sublateral 

 longitudinal carina of second tergite present and distinct only on 

 basal 0.25 of the tergite, but indicated also at very base of third tergite 

 (in other species of the genus the sublateral longitudinal carina of 

 second tergite extends its entire length); median longitudinal carina 

 extending almost entire length of second tergite and present on basal 

 0.5 of third tergite.
