 punctate; first segment of flagellum shorter than the second and 

 third segments united, one and one-third times as long as it is broad 

 at the apex; antennal scrobes not carinate above; front and vertex 

 closely, confluently punctate, the genae with the punctures more 

 spearated; head subquadrate, the sides behind the eyes not con- 

 verging to meet the postero-lateral angles; posterior portion of the 

 head truncate, the margin slightly sinuate ; postero-lateral angles very 

 prominent, bearing a large, subreniform, glabrous tubercle; relative 

 widths of head and thorax, 7.5-8. 



Thorax dark ferruginous; junction of the cephalic face and dorsum 

 of pronotum angulate; pronotum and mesonotum coarsely, deeply 

 and confluently foveolate, clothed with sparse appressed, golden 

 pubescence, and scattered, dark, erect hairs; propleura with large, 

 confluent punctures anteriorly, indistinctly punctured posteriorly; 

 anterior half of mesopleura closely, minutely punctate, the posterior 

 half coarsely, confluently foveolate ; metapleura glabrous, impunctate 

 except for a few, scattered, large punctures ventrally; sides of pro- 

 podeum with large, distinct, separated punctures; posterior face of 

 propodeum closely punctate ventrally, coarsely, confluently foveolate 

 on the dorsal half; dorsal half of propodeum with a thin brush of 

 long, erect, golden pubescence; scutellar scale prominent. 



Abdomen very dark mahogany red, almost black; first tergite ma- 

 hogany red, with large, more or less confluent punctures throughout, 

 . clothed with sparse, long, erect, silvery pubescence, and a thin apical 

 fringe of black hairs, second tergite dark mahogany red, almost 

 black, with a very large campanulate, yellow spot occupying the 

 entire disk; the second tergite with very large, deep, more or less 

 confluent punctures throughout, the punctures sparser at the sides; 

 pubescence of the maculation of the second tergite sparse, appressed 

 and golden, of the base black, the sides silvery, and the subapical 

 margin and apical fringe (except laterally) black; tergites 3-5 

 closely, deeply punctate; tergite 3 with the pubescence and apical 

 fringe black (except laterally), tergites 3-5 closely, deeply punctate; 

 tergite 3 with the pubescence and apical fringe black (except later- 

 alUy), tergites 4-5 with silvery pubescence; pygidium distinctly re- 

 flexed at the sides, longitudinally striate, the striae not reaching the 

 tip, the subapical portion minutely reticulate; first sternite with a 

 prominent longitudinal carina, with large, close punctures, and 

 clothed with sparse, long, erect, silvery pubescence; second sternite 

 with deep, large, elongate, distinct punctures throughout, sparsely 

 clothed with long, erect, silvery pubescence; sternites 3-5 closely, 

 confluently punctate ; sternites 2-4 with thin apical fringes of silvery 

 pubescence ; sternite 5 with the apical fringe black.
