rated punctures; eyes abnormally large, entirely covering the sides 

 of the head, almost touching the base of the mandibles; ocelli abnor- 

 mally large ; two to three times as large as usual ; relative widths of 

 head and thorax, 6.75-8. 



Thorax dark mahogany red, almost black; pronotum, mesonotum, 

 scutelliim, and metanotnm with long, erect, dense, yellow pubescence, 

 the remainder of the thorax with sparse, long, erect, black pubescence ; 

 cephalic face of pronotum punctate laterally, glabrous, impunctate, 

 emarginate medially, not rounded evenly into the dorsum medially; 

 dorsum of pronotum, mesonotum, and scutellum densely, coarsely 

 punctate; narrow basal and lateral margins of tegulae setigerously 

 punctate, for the most part glabrous, impunctate; propleura with 

 scattered, indistinct punctures; mesopleura with scattered, large punc- 

 tures near the anterior margin, elsewhere with deep, coarse contiguous 

 punctures; metapleura glabrous, with fine, indistinct, scattered punc- 

 tures, and a few, large punctures ventrally; sides of propodeum 

 glabrous, impunctate at the anterior margin, irregularly, broadly 

 reticulate elsewhere; posterior face and dorsum of propodeum 

 coarsely, foveately reticulate. 



Abdomen dark mahogany red, almost black; apical margin of 

 second tergite, tergites 3-6 and base of ultimate tergite, all vfith long, 

 erect, dense, yellow pubescence; remainder of abdomen with long, 

 sparse, erect, black pubescence; apical fringes of sternites black; 

 first segment nodose; first tergite coarsely, confluently punctate; 

 second tergite with large, dense, more or less confluent punctures 

 throughout, closer and more confluent anteriorly than posteriorly; 

 tergites 3-6 densely punctate; pygidial area irregularly rugose; first 

 sternite with large, indistinct punctures, the median carina prominent, 

 produced slightly both anteriorly and posteriorly; second sternite 

 with large, shallow, elongate, more or less confluent punctures 

 throughout; sternites 3-6 with small, scattered punctures near the 

 apical margin; ultimate sternite distinctly punctate. 



Legs dark mahogany red, sparsely clothed with long, black pu- 

 bescence; calcaria black. 



Wings fuliginous; cell 2nd Ri + R2 broadly truncate at the apex; 

 cell R4 almost obsolete; vein M3+4 received by cell Rr, at one-third 

 the distance from the base to the apex; veins r-m and Rg approxi- 

 mate, but not touching on vein r; vein r-m long and sinuate.
