 cence intermixed with scattered pale erect hairs; first segment of 

 flagellum subequal to the second ; lateral processes of scutellum small 

 and punctate ; middle and hind femora squarely truncate at the tips,

Head, black, clothed with sparse, long, erect, black pubescence, 

 except the vertex with sparse, long, erect, silvery gray pubescence; 

 mandibles acute at the apex, apparently very indistinctly dentate

 ally; disk of clypeus densely, confluently punctate; scape bicarinate 

 beneath, the one carina strong, prominent, the other weak, indistinct, 

 closely punctate above; first segment of flagellum subequal in length 

 to the second; antennal scrobes carinate above; front densely, con- 

 fluently punctate; vertex closely punctate, somewhat less coarsely 

 sculptured than the front ; genae with moderate, separated punctures, 

 less coarsely sculptured than the vertex ; relative widths of head and 

 thorax, 6.25-7.

 except the pronotum with sparse, long, erect, silvery gray pubescence ; 

 cephalic margin of pronotum not emarginate medially; pronotum, 

 mesonotum and scutellum densely, confluently punctuate; propleura 

 with large, contiguous punctures anteriorly and shallow, indistinct 

 punctures posteriorly; mesopleura with large, contiguous punctures, 

 except the punctures separated and sparse anteriorly; ventral third 

 of metapleura coarsely, confluently punctuate, the dorsal two-thirds 

 glabrous, impunctate; anterior half of sides of propodeum glabrous, 

 impunctate, the posterior half and the posterior face and dorsum of 

 the propodeum deeply, coarsely, foveately reticulate; tegulae 

 glabrous, impunctate, except the basal and inner lateral margins 

 setigerously punctate. 



Abdomen ferruginous, except the first segment black, clothed with 

 sparse, long, erect, black pubescence, intermixed with scattered, erect, 

 pale hairs; first tergite coarsely, densely, confluently punctate; sec- 

 ond tergite with large, coarse, contiguous punctures throughout ; ter- 

 gites 3-6 densely, confluently punctate; pygidium irregularly 

 rugose; first sternite punctate and with a median, longitudinal 

 carina, the latter most prominent anteriorly; second sternite with 

 large, close punctures throughout; sternites 3-6 punctate at the 

 apical margins; last sternite moderately punctate. 



Legs black, clothed with long, sparse, blackish pubescence; middle 

 and hind femora squarely truncate at the apex, the surface of the 

 truncations sulcate ; calcaria pale.
