Size, medium. Vertex but little elevated above the pronotum, the 

 interspace between the eyes a fourth wider than (male) or fully twicft 

 as wide (female) as the first antennal joint; the front half strongly 

 sloping, distinctly sulcate in the male, feebly in the female. Frontal

costa as broad as the interspace between the eyes, deeply sulcate be- 

 low the ocellus in the male. Antenna about three-fourths (male) 

 or two-thirds (female) as long as hind femora. Pronotum feebly ex- 

 panding on posterior half, the disk flat or nearly so; the hind margin 

 obtuse angled, more so in the female; the median carina visible 

 throughout, more distinct on the metazona; the prozona about equal 

 to the latter in length. Tegmina slightly surpassing the tip of hind 

 femora, distinctly though very gradually tapering. Extremity of 

 male abdomen well recurved; the cerci sub-falcate, tapering rapidly 

 from base to middle, the apical third but little expanded, the apex 

 very obliquely truncate and somewhat incurved. Furcula consisting 

 of a pair of tapering cylindrical spines, about half as long as the 

 supra-anal plate, their apical two-thirds well separated and lying just 

 outside the ridges fonning its median sulcus. Sub-genital plate with 

 its apex less than half the breadth of the base, not elevated, truncate, 

 and distinctly rounded. (See Fig. 11, Plate II.)
