Vertex tumid, considerably elevated above the pronotum; inter- 

 space between the eyes half as broad again as the basal antennal joint, 

 the fastigium shallow, indistinct, broad, enlarging apically; frontal costa 

 broad, equal, flat (male) or slightly tumid (female) above, sulcate 

 below; antennae three-fourths (male) or hardly two thirds (female) as 

 long as the hind femora. Pronotum simple, scarcely enlarging on the 

 metazona, the front border straight, the hind border roundly and 

 broadly angulate; median carina distinct though rather slight, equal; 

 lateral carinae scarcely perceptible; metazona faintly punctate; pro- 

 zomi slightly longitudinal (male) or quadrate (female), about a fourth 

 longer than the metazona. Prosternal spine moderately long, cylin- 

 drical, blunt, erect; interspace between mesosternal lobes twice (male) 

 or almost twice (female) as long as broad; metasternal lobes attingent 

 (male) or approximate (female). Tegmina a little longer than head and 

 pronotum together, tapering, the dorsal and lateral fields angularly 

 separate. Supiaanal plate of male triangular, longer than broad, 

 pointed, the sides straight; furcula consisting of a pair of approximate, 

 small, triangular teeth, the tips a little produced ; cerci forming on each 

 side a broad, semicircular, rounded flap, the upper side concave, the 

 lower convex, the tip rounded, the whole in one plane; subgenital plate 

 conical, longer than broad, the tip compressed. 



The general color is a yellowish or cinereous brown above, a paler 

 brownish yellow below. The antennae are pale red, infuscated apically ; 

 a very broad, straight, piceous belt, slightly larger behind than in 

 front, extends from behind the eyes across the prozona, its upper edge
