than face; mandible more than a half longer than broad at base, 

 narrowed toward apex; junction of occipital and hypostomal carinae 

 distant from base of mandible more than basal width of latter, the 

 lower cheek deeply excavated and the hypostomal carina very high 

 and thin and arched outward; eyes very strongly convex, longer than 

 width of face and distinctly convergent below; postocellar and ocell- 

 ocular lines equal and about twice as long as diameter of a lateral 

 ocellus; antenna nearly as long as body, slender, and rather attenuate 

 at apex, 52- to 54-jointed, basal joint of flagellum fully twice as long 

 as second, the latter two and a half times as long as thick. 



Thorax strongly compressed, polished, Avith rather sparse puncta- 

 tion, coarser on plem-a; notauli absent; scutelium sub triangular, dis- 

 tinctly flattened above, precipitous behind, strongly margined to top 

 of apical slope; propodeum finely reticulate rugose above, coarsely 

 so medially, very coarsely longitudinally rugose behind the medially 

 prominent apical carina ; pleural carina indicated by marked difference 

 in sculpture of propodeum and of metapleurum; spiracles elongate, 

 situated far above pleural carinae. 



Legs slender, rather short, the hind femur not reaching apex of 

 abdomen, fully three-fourths as long as tibia; inner hind calcarium 

 distinctly more than half as long as basitarsus, apical joint of tarsus 

 nearly as long as third joint. 



Wings: Apical abscissa of radius moderately curved at base, barely 

 a half longer than basal abscissa; areolet shortly petiolate or sub- 

 sessile, irregular, with recurrent before middle; second discoidal cell 

 about a half longer on subdiscoideus than broad at apex; second re- 

 current strongly subangulate above; nervulus shortly postfurcal to 

 interstitial, abscissula about twice as long as intercubitella. 



Abdomen polished, slender, strongly compressed at apex; first 

 tergite about two and a half times as long as broad, its sides concavely 

 curved, second tergite longer than broad at base; ovipositor straight, 

 sheath three-fourths as long as first tergite. 



Black, with abdomen, except more or less of petiole, and hind femur, 

 more or less, ferruginous ; front and middle legs more or less reddish 

 in front; apical three joints of hind tarsus somewhat reddish; sheath 

 black; M^ngs subhyaline, veins black, stigma paler. 



Male. — Essentially like female, but front and middle femora pale 

 ferruginous, their tibiae and tarsi more yellowish; hind tibia at 

 extreme base and joints 2-4 or 3-4 of tarsus pale yellow; genital 

 sheath largely piceous.
