 above, dorsum of thorax, abdomen above, and apical fringes of 

 abdominal sternites in part, yellow; cephalic margin of pronot'um 

 not emarginate; last abdominal tergite with an apical fringe of erect 

 hairs; second abdominal sternite without a median pit or longi- 

 tudinal row of hairs simulating a carina. Length, 9.5 mm. 



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

 the front and vertex clothed with sparse, long, erect, yellow pubes- 

 cence; mandibles acute at the apex, bidentate within near the apex; 

 apical margin of clypeus bidentate medially ; disk of clypeus densely, 

 confluently punctate; scape weakly bicarinate beneath, coarsely, 

 closely punctate; first segment of flagellum suequal in length to the 

 second, especially when measured beneath; antennal scrobes weakly 

 carinate above; front with large, dense, confluent punctures; vertex 

 with large, mostly separated but somewhat confluent punctures ; rela- 

 tive widths of head and thorax, 5.75-6. 



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

 except the pronotum, mesonotum, scutellum, and postscutellum with 

 long, somewhat dense, erect, yellow pubescence; cephalic margin of 

 pronotum not at all emarginate medially ; pronotum, mesonotum, and 

 scutellum with large, dense confluent punctures ; propleura with large, 

 close punctures and a small area of fine punctures near the pos- 

 terior margin ; mesopleura with coarse punctures, dense and confluent 

 medially, separated at the anterior and posterior margins; meta- 

 pleura glabrous, impunctate except for scattered punctures ventrally ; 

 anterior margin of sides of propodeum glabrous, impunctate, the 

 posterior half coarsely, foveately reticulate; posterior face and 

 dorsum of propo leum deeply and very coarsely, foveately reticulate ; 

 tegulae glabrous and impunctate, except the basal and inner lateral 

 fourths setigerously punctate, the pubescence yellow. 



Abdomen black, clothed with sparse, black, erect pubescence, ex- 

 cept the apical half of the second tergite, tergites 3-6, base of last 

 tergite, clothed with long, somewhat dense, erect, yellow pubescence; 

 apical fringes of first tergite medially, sternites 2-3, and sternites 4 

 and 5 laterally, yellow; first tergite coarsely, confluently punctate; 

 second tergite with large, deep punctures separated medially, dense 

 and somewhat confluent basally and laterally; tergite 3-6 densely 

 confluently punctate; pygidial area longitudinally rugose, with an 

 apical fringe of short, erect hairs; first sternite deeply punctate and 

 with a median longitudinal carina; second sternite vv^ith large, deep 

 punctures, sparse medially, somewhat dense basally and laterally, 

 without a median pit filled with hairs, or a longitudinal row of hairs
