NO. 1124. RE VISION OF THE MELA XOPLISC UDDER. 9 1 



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

 femora of the male and the brevity of the cerci, exposing so fully the 

 infracercal plates; it has considerably longer hind legs than B. referta, 

 which it most resembles in general appearance.

Body stout, compact, transversely subquadrate, thinly pilose. Head 

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

 the male, as the length of the lateral carinae of the raetazona, the sum- 

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

 fastigiuni 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 infraocular portion of the 

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

 nearly as broad as the upper aspect of the eyes; fastigiuni 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 

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

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

 divergent; antennae slender, long, about half as long as the body, oven 

 in the female. Pronotum feebly subsellate, the anterior margin flaring 

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

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

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

 the macropterous forms; disk of prozona feebly convex transversely, 

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

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

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

 percurrent, median carina; prozona smooth excepting its subrugose 

 anterior margin, subtrans verse, half as long again as the punctato- 

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

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

 by a still deeper, scarcely arcuate, percurrent sulcus, from which there 

 runs backward, on the middle of either side, a short impressed line. 

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

 distinctly longer than broad in both sexes, rapidly narrowing behind, 

 so that the portion posterior to the metasternal lobes is only about half 

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

 sternal lobes in both sexes distinctly transverse, broader than the lobes 

 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
