 the cephalic . face of the emargination glabrous, impunctate ; re- 

 mainder of cephalic face of pronotum punctate and pubescent; 

 pronotum, mesonotum, and scutellum with large, dense, confluent 

 punctures; posterior margin of pronotum immediately anterior to 

 the tegulae defined by a carina; dorsal and anterior areas of pro- 

 pleura punctured like the pronotum, the posterior portion indis- 

 tinctly sculptured with intermixed moderate and fine punctures; 

 mesopleura with large, deep, confluent punctures medially, the 

 punctures becoming sparse and smaller both posteriorly and an- 

 teriorly; ventral half of metapleura coarsely, confluently punctate, 

 the dorsal half glabrous, impunctate; sides of propodeum coarsely, 

 foveately reticulate, except towards the anterior margin the sculpture 

 less coarse and deep ; posterior face and dorsum of propodeum very 

 coarsely, deeply and foveately reticulate; tegulae dark ferruginous, 

 the basal half setigerously punctate, the apical half glabrous, impunc- 

 tate, the pubescence on the basal half yellow. 



Abdomen black, clothed with black pubescence, except apical half 

 of second tergite, tergites 3-6, and base of last tergite clothed with 

 long, erect, yellow pubescence; first tergite densely, confluently 

 punctate; basal half of second tergite (that is area with black pubes- 

 cence) densely, confluently punctate, the punctures of moderate 

 size, the apical half with distinct, separated punctures; tergites 

 3-6 with small, close punctures; last tergite with an apical fringe 

 of erect hairs at the apical margin, the pygidial area glabrous; 

 first sternite punctate and with a median longitudinal carina ; second 

 sternite with large, deep punctures, the latter sparse medially, close 

 and dense laterally and basally; second sternite without a median 

 pit or row of hairs simulating a carina ; sternites 3-6 with scattered 

 p'unctures near their apical margins; basal two-thirds of last ster- 

 nite punctate ; sternites 2-6 with black apical fringes. 



Legs black, clothed with long, black pubescence; calcaria black. 



Wings dark fuliginous; cell 2nd R^ + Ej squarely truncate at the 

 apex; cell E4 indistinct; vein M3+4 received by cell Eg about one- 

 third the distance from the base to the apex; veins r-m and E^ 

 coalescing on vein r. 



Holatype. — Male, Ormsby county, Nevada, July (Baker), in col- 

 lection of Cornell University. 



This is very much like coccineohirta Blake, especially in color and 

 general sculpture. It differs from the latter in the large, conspicu- 

 ous ocelli, and in having an apical fringe of hairs on the last tergite. 

 The genitalia are also dissimilar as will be seen by a comparison 

 of the figures.
