This species is remarkable for the slenderness of the fore and middle 

 femora of the male and tlie brevity of the cerei, exposing so fully the 

 iiifracercal jdates; it has considerably lonjjer hind legs than B. rvfcria, 

 which it most resembles in general appearance.

Body stout, compact, transversely sub(piadiate, thinly jiilose. Head 

 large, broad, a little prominent, with the eyes fully as wide, at least in 

 the male, as the length of the lateral <arinae of the metazona, the sum- 

 mit well arched, raised a little above the level of the luonotum, the 

 fastigium rapidly descending and forming an obtuse angle with the very 

 straight and slightly receding face; eyes rather small but very promi- 

 nent in both sexes, nearly as broad as long and no longer (female) or 

 scarcely longer (male) than the anterior intraocular portion of the 

 genae; interspace between the eyes exceptionally broad, in the female 

 nearly as broad as the upper asi)ect of the eyes; fastigium feebly con- 

 vex as far as the front margin of the eyes, in front of which it is 

 depressed; frontal costa only moderately broad, much narrower than 

 tlie interspace between the eyes, obsolescent below the ocellus, owing 

 to the breadth of the face, the lateral carinae are more than usually 

 divergent; antennae slender, long, about half as long as the botly, even 

 in the female. Pronotum feebly subsellate. the anterior margin tlaring 

 to receive the head, and the metazona both expanding and having its 

 dorsum raised at a slight angle with the prozona; front margin slightly 

 convex; hind margin slightly more convex, feebly emarginate, even in 

 the macropterous forms; disk of prozona feebly convex transversely, 

 of metazona idane, passing with a distinct angle into the vertical lateral 

 lobes, more distinct on metazona than on prozona, so that, at least on 

 the metazona, there are distinct lateral carinae, besides a well-defined 

 percurrent, median carina; prozona smooth excepting its subrugose 

 anterior ^nargin, subtransv^erse, half as long again as the punctato- 

 ruguloss metazona, cut rather deeply in the middle by a straight trans- 

 verse sulcus, followed at less than half the distance to the metazona 

 by a still deeper, scarcely ar(;uate, percurrent sulcus, from which there 

 runs backward, on the middle of either side, a short imi)resse<l line. 

 Prosternal spine stout, erect, conical; meso- and metastethia together 

 distinetly longer than broad in both sexes, ra])idly narrowing behind, 

 so that the i)ortion posterioi" to the metasternal lobes is only about half 

 the greatest width of the inetastethium; interval between the meso- 

 sternal lobes in both sexes distinctly transverse, broader than the h)bes 

 themselves; metasternal lobes rather distant (male) or distant (female), 

 at least as widely separated as the breadth of the frontal costa. 

 Tegmina fully developed or abbreviate, their inner edges in neither
