gense with very coarse, oblique wrinkles between antennae and 

 outer margin; remainder of face finely shagreened. Head dis- 

 tinctly wider than pronotum; length of vertex into width be- 

 tween eyes little less than four times, its length at middle slightly 

 more than at eyes. Face slightly broader than long, ocelli about 

 as near to median line as to eyes; distance between ocelli two 

 and a half times the width of clypeus at base; supra-antennal 

 ridges reaching eyes; frontoclypeal suture distinct; clypeus 

 small, narrow, broader at apex than at base, slightly emarginate 

 at apex; lorse small but broad, more than half the width of 

 clypeus. Width of pronotum two and one-fourth times the 

 length, the length two and a half times that of vertex ; anterior- 

 margin distinctly more strongly arcuate than posterior ; surface 

 coarsely shagreened. Scutellum as long as pronotum and one

third of vertex together, entire surface of anterior field coarsely 

 shagreened, posterior field minutely, transversely rugose; trans- 

 verse impressed line slightly bent at middle, the lateral extrem- 

 ities transverse. Tegmina very coarsely thimble-pitted along the 

 veins, these pits much more numerous and conspicuous on cla- 

 vus and base of corium where they are centrally pimpled. Veins 

 more distinct than in B. scutellaris, the third apical cell broad- 

 ened apically. Last ventral segment and pygofers of female 

 pale brown, and ovipositor dark brown, in striking contrast to 

 color of remainder of venter. Hind margin of anal segment of 

 female subtruncate.

These two species illustrate, at its best, the remarkable diver- 

 gence in structural characters among some of these idiocerine 

 insects, in spite of the unusual homogeneity in general habitus.
