femora in part; anterior surface of tibiae; and tarsi more or less; 

 pale yellow. 



The pubescence is inconspicuous, though the labrum and the basal 

 segments of the legs show a slight silveriness. The flagellum is 

 black. The dorsum of the thorax, especially the scutellum, shows 

 a beautiful metallic irridescence. In color the maculations of the 

 head are a greenish yellow, of the body pale, and of the legs rich 

 yellow. On the front legs all segments of the tarsus are marked with 

 yellow, on the second pair only the first and last segments, and on 

 the third pair only the metatarsus. The wings are almost hyaline, 

 showing only very slight uniform infumation. The sixth tergite 

 bears a pygidial area set off by weak, lateral lines or ridges. The 

 middle part of the pygidial area is devoid of punctures and its lateral 

 areas are covered with coarse, rather widely separated punctures. 

 The areas laterad of the ridges are covered wnth fine, closely-placed 

 punctures. The sixth sternite, which extends laterad of the sixth 

 tergite much as is the case with B. capnoptera Handlirsch, is dis- 

 tinctly carinate on the midline and is finely punctulate with a few 

 scattered coarser punctures. 



Length 15 mm. The species is described from a single female 

 from Cayenne, South America. 



Type (female). — In the Carnegie Museum at Pittsburgh, Pa.

I have before me three females that I have referred to this species, 

 which differs from all other species in the genus in having the dorsal 

 angle of the posterior-lateral margin of the propodeum drawn out 

 into a point. The fasciae on both tergites and sternites are usually 

 broad and continuous, but on one of the three females at hand the 

 fasciae on tergites 1-3 are very narrowly interrupted. The legs are 

 almost wholly ferruginous and the wings are slightly and uniformly 

 infumated.
