Of inediuiii or slightly al)ove niedium size. Head not prominent, the 

 vertex feebly tumid, si-arcely elevated above the pronotum, the inter-

 (female) as the tirst antennal joint; fastiginm ratiier steeply declivent, 

 broad, shallow, enlarging slightly in front, the bounding walls low and 

 rounded; frontal costa moderate, equal, as broad as (male) or slightly 

 narrower than (female) the interspace between the eyes, tiat, sunken a 

 little at the ocellus, and in the female sulcate below it, biseriately 

 punctate above; eyes large, rather prominent, very much longer, espe- 

 cially in the male, than the intraocular portion of the genae; antennae 

 fidly two thirds (male) or a little more than one-half (female) as long as 

 the hind femora. Pronotum simple, eiiual, the front margin ji little full, 

 the hind margin gently angulated; median carina distinct though 

 rather slight, equal; lateral carinae rounded off; prozona faintly and 

 distantly, metazona abundantly but not deeply punctate; prozona dis- 

 tinctly longitudinal and similar in the two sexe.s, fully half as long 

 again as the metazona. i'rosternal spine large, long, subcylindrical, 

 blunt, a little retrorse; interspace between mesosternal lobes three times

 consisting of a pair of minute, rounded, aj)proximate, flattened lobes, 

 as long as broad; cerci with the basal half tapering by the rapid slop-

 beyond broadening again somewhat on the same side, so that theapic;il 

 half is subspatulate, continuous with the basal part but strongly 

 incurved, externally deeply channeled, the tip broadly rounded, tlie 

 whole about as long as the last Joint of the fore tarsi; subgenital i)late 

 very small and narrow, tumid, apically subtuberculate, the apical 

 margin slightly elevated, entire. 



The general color is a griseous brown, excepting the abdomen wliich 

 is brownish testaceous; beneath clay yellow: the antennae are yellow 

 at the base, darkening beyond to fuscous ferruginous; from behind 

 the eye a broad bliick band extends across the prozona, generally 

 enlivened on the genae by an oblique yellow streak, which in the
