Very closely allied to crassisculptus, from wliicb it is immediately 

 distinguishable by the black hind coxa and femur. Differs from the 

 above description of crassisculptiLS as follows: 



Female. — Temples more weakly convex and more strongly reced- 

 ing; eyes barely shorter than width of face, more distinctly convergent; 

 diameter of a lateral ocellus half as long as ocellocular line; scutellum 

 in profile evenly convex, not precipitous behind ; abdomen even more 

 slender, first tergite about two and a half times as long as broad at 

 apex, second a half longer than broad at base. 



Clypeus entirely black, mandibles usually so; scape usually more 

 or less black ; antennal annulus distinct ; anterior margin of pronotum 

 only medially ferruginous; mesoscutum with a more or less distinct 

 median black vitta and usually with lateral vittae; scutellum yellow; 

 all coxae entirely, hind femur except more or less at base, apical half 

 of hind tibia, and all but apex of basitarsus black; tibiae basally and 

 hind tarsus except basally yellow; abdomen usually more or less black 

 at apex, this color sometimes extending as far forward as base of 

 fourth tergite.
