punctate; third tergite coarsely, confluently punctate; fourth and 

 fifth tergites with small, separated punctures ; pygidial area rugose ; 

 first tergite coarsely, confluently punctate, the median, longitudinal 

 carina not well defined; second sternite scabrous at the sides and 

 subapically, elsewhere shallowly foveate; sternites 3-5 densely, 

 confluently punctate. 



Legs dark ferruginous, sparsely clothed with long, pale pubescence ;

Male. — Ferruginous, the head and thorax somewhat darker than 

 the abdomen; clothed with sparse, somewhat appressed, pale golden 

 pubescence on the head and thorax above and the abdomen from and 

 including the apical half of the second tergite, the propodeum, basal 

 half of second tergite, head beneath, and thorax on sides and beneath 

 with sparse, black pubescence ; disk of second abdominal sternite dis- 

 tinctly concave, scabrous at the sides and subapically; trochanters 

 produced at the apex within into a prominent tooth. Length, 12 mm. 



Head very dark ferruginous ; front and vertex clothed with sparse, 

 somewhat appressed, pale golden pubescence, elsewhere with sparse, 

 erect, blackish pubescence; mandibles tridentate; apical margin of 

 clypeus prominently bidentate medially; disk of clypeus densely, 

 confluently punctate; scape bicarinate beneath, closely punctured 

 above; first segment of flagellum distinctly shorter than the second 

 dorsally, subequal ventrally; antennal scrobes carinate above; front 

 and vertex coarsely, more or less confluently punctured; genae with 

 moderate ; close punctures, not as coarsely sculptured as the front and 

 vertex; relative widths of head and thorax, 6.5-8, 



Thorax very dark ferruginous, except the pronotum and propo- 

 deum lighter in color ; pronotum, mesonotum, and scutellum clothed 

 with long, somewhat appressed, pale golden pubescence, the remain- 

 der of the thorax with sparse, blackish pubescence ; pronotum, meso- 

 notum, and scutellum very coarsely, densely, confluently punctate; 

 propleura confluently punctate at the margins, indistinctly punctate 

 medially; mesopleura with large, distinct punctures on the anterior 

 half and at the posterior margin, elsewhere the large punctures dense, 

 somewhat confluent; metapleura glabrous, impunctate except for a 

 few coarse, confluent punctures at the ventral margin ; sides, posterior 

 face and dorsum of propodeum coarsely, f oveately reticulate ; tegulae 

 glabrous, impunctate, except the basal and inner lateral margins 

 setigerously punctate. 



Abdomen ferruginous ; basal half of second tergite and basal third 

 of apical tergite with sparse, appressed and erect black pubescence, 

 elsewhere with sparse, pale golden pubescence; first segment subses- 

 sile; first tergite coarsely, confluently punctate, more densely so at
