tate ; propodeum weakly convex to the very short, distinct, precipitous 

 petiolar area, pleural carina absent before spiracle; spiracles small, 

 broadly oval. 



Legs long, moderately slender; hind femur reaching distinctly be- 

 yond apex of abdomen ; longer hind calcarium nearly two-thirds as long 

 as basitarsus. 



Wings: Apical abscissa of radius weakly curved, hardly twice as 

 long as basal abscissa; areolet large, with second intercubitus nearly 

 straight and unusually long so that the areolet is narrower than usual 

 with its outer angle sharply acute, recurrent at middle ; second discoidal 

 cell rather narrow, basal abscissa of subdiscoideus more than a half 

 longer than second recurrent, the latter nearly straight; nervulus 

 interstitial; absdssula more than a half longer than intercubit.ella. 



Abdomen polished, little longer than head and thorax, strongly 

 depressed except at extreme apex, where it is weakly compressed; first 

 tergite more than half as broad at apex as long, its sides weakly con- 

 cavely curved; second tergite hardly longer than broad at base; ovi- 

 positor only briefly exserted, sheath barely half as long as first tergite. 



Head and thorax black with j^ellow markings as follows: Clypeus 

 except its brownish apex; mandibles; annulus embracing flagellar 

 joints 9-14; broad anterior margin and humeral angle of pronotum; 

 two large spots on anterior margin of mesoscutum; scutellum and 

 postscutellum ; tegulae; subalar tubercle; upper posterior angle and a 

 large spot on lower posterior angle of mesopleurum; and a large spot at 

 apex of metapleurum confluent with a narrower band across apex of 

 propodeum; legs ferruginous, front and middle coxae entirely and 

 trochanters partly yellow, all tibiae at base yellowish, hind tibia 

 narrowly blackish at apex, hind tarsus blackish with a yellow annulus 

 embracing second joint and apical half of basal joint; wings hyaline, 

 venation brown, stigma paler; abdomen ferruginous, first tergite more 

 yellowish, sheath concolorous.
