EEYISION OF THE GENUS EXETASTES CUSHMAN 263 



coarsely punctate than the faintly coriaceous apical portion; cheeks 

 in front view straight, their extended angle very acute; malar space 

 two-thirds as long as basal width of mandible, mat; mouth very 

 broad, broader than face ; mandible more than twice as long as broad 

 at base, strongly curved; junction of occipital and hypostomal carinae 

 shortly behind base of mandible ; eyes small, broadly oval, prominent, 

 parallel, shorter than width of face; postocellar and ocellocular lines 

 equal and distinctly more than t\vice as long as diameter of a lateral 

 ocellus; antenna slender filiform, about 50-jointed, only slightly taper- 

 ing, first joint of flagellum barely twice as long as second, second joint 

 more than twice as long as thick. 



Thorax nearly twice as long as deep, very finely and rather densely 

 punctate; notauli very broadly and weakly indicated; scutellum 

 evenly convex, polished, sparsely punctate; propodeum evenly convex 

 both transversely and longitudinally, finely irregularly reticulate 

 rugulose, more coarsely and transversely so laterally toward apex, 

 without carinae, pleural carina at most obsoletely indicated, spiracles 

 rather small, elongate oval, far above pleural carina. 



Legs not especially long; front and middle legs slender; hind femur 

 rather stout, little more than two-thirds as long as tibia and hardly 

 reaching to apex of abdomen; inner hind calcarium less than half as 

 long as basitarsus; apical joint of hind tarsus nearly as long as third 

 joint. 



Wings: Apical abscissa of radius strongly curved at base, much less 

 than twice as long as basal abscissa; areolet large, regular, subsessile, 

 recurrent at middle; second discoidal cell rather long, second recurrent 

 hardly two-thirds as long as basal abscissa of subdiscoideus, nearly 

 straight; nervulus distinctly postf ureal; abscissula a half longer than 

 intercubitella. 



Abdomen slender, especially in profile; polished and impunctate, 

 except first tergite laterall}^ toward base; first tergite more than half 

 as broad at apex as long, tergites 2-4 as long as broad at base; oviposi- 

 tor long, stout, strongly recurved, sheath more than half as long as 

 abdomen. 



Head and thorax black; apex of clypeus brownish or yellowish; 

 small spot at top of eye yellow; abdomen ferruginous with first two 

 tergites more or less and ventral plica and hypopygium blackish; legs 

 black, front femur and tibia anteriorly, middle femur apically, yellow- 

 ish, hind femur more or less ferruginous on outer surface and rarely 

 largely ferruginous, in the latter case the tibia largely ferruginous; 

 hind tarsus with joints 2-4 sometimes dark reddish; wings uniformly 

 dark infumate. 



Male: — Essentially like female but malar space shorter, ocelli larger, 

 temples more strongly convex; apical portion of clypeus pale yellow; 

 pattern of front and middle legs much as in female but black largely
