clypeus it is short, dense, and silvery. The frons is wide, weakly 

 earinate between the antennae, and the inner eye-margins are ap- 

 proximately parallel. The anterior metatarsus bears six spines. The 

 disk of the second sternite is shining and bears scattered, coarse 

 punctures. The apical part of the sixth tergite is plainly earinate 

 at midline. 



In Handlirsch's table this species runs, although not accurately, to 

 B. tricolor Dahl. It differs from that species in having no black on 

 the clypeus and in the absence of any maculations on the sides of the 

 mesothorax, metathorax, and propodeum. Furthermore, the wings 

 of this species are strongly infumated at the base, while the apical 

 portion is hyaline. The insect is decidedly slender in form and the 

 sixth tergite is broadly rounded at the apex.

Type (female). — Black: labrum; mandibles, except tips; clypeus, 

 except pair of large, dark basal areas; scape below; lower part of 

 frons; pair of rounded spots below anterior^ ocellus; broad, anterior 

 orbits barely reaching the level of anterior ocellus; broad, posterior 

 orbits, each greatly narrowed and interrupted at vertex; prothorax, 

 except anterior transverse dorsal spot and dusky line in front of 

 tubercles; broad, lateral lines and pair of vary narrow, obscure, 

 longitudinal, discal lines on scutum; narrow fascia on posterior bor- 

 der of scutellum; very narrow fascia on metanotum; shortened 

 fascia on propodeum interrupted, at midline; almost the entire 

 side of propodeum (but not the lateral angles) ; anterior portion 

 of metapleura; mesopleura almost wholly; fascia on first tergite 

 narrow and interrupted at dorsal midline; fascia on second ter- 

 gite broader, interrupted at midline and bisinuate on anterior 

 dorsal border; fascia on third similar to that on second; fascia 

 on fourth similar to those on second and third, but continuous ; 

 fascia on fifth broken into a central and lateral spots; apical por-

 margin of sternite 6 ; legs, except more or less of the coxae and trc »-

 and one below on posterior femora; yellows, which varies in shade on 

 different parts of the bodj^ 



The maculations on the dorsal part of the thorax and on the abdo- 

 men are decidedly pale, whereas those on the sides of the thorax 

 and on the legs show a tendency toward ferruginous. The flagellum
