 and mesosternum very sparsel}^, weakly punctured; propodeum 

 convex in profile, carinae subparallel and reaching to about middle; 

 spiracles rather small and nearly round; abdomen rather slender, 

 third tergite nearly two-thirds as long as wide; first tergite with 

 dorsal carinae reaching beyond middle, anterior basin occupying 

 little more than half dorsal length; tegulae entirely 3^ellow; color 

 pattern not repeated on front tibiae; antennae brown beneath; 

 wings brownish hyaline, stigma brown with apex and base but

 type h and c reared by A. Koebele in Alameda County, California, 

 b in June from Evceratia castella (Bur. Ent. No. 217°) and c in August

Female. — Length, 8 mm.; antennae, 6 mm.; ovipositor, L5 mm. 



Differs from description of ohesus as follows: face with well 

 separated punctures; malar space nearly half as long as basal 

 width of mandible; postocellar line longer than diameter of lateral 

 ocellus, which is less than twice as long as ocell-ocular line; meso- 

 scutum sparsel^y, weakly punctate, mesopleura and mesosterum 

 even more weakly so ; propodeum convex in profile, dorsal carinae 

 strong only at base but extending obsoletely nearly to middle, 

 spiracles rather small, nearly round; abdomen narrow, third tergite 

 nearly two-thirds as long as wide, first tergite with dorsal carinae 

 extending beyond middle, anterior basin but little more than half 

 total length of tergite; all palpi pale; antennae brown; wings 

 brownish stained.

Other localities. — White Mountahis, New Mexico; Fort Wrangel, 

 Alaska.
