Of rather small size, blackish fuscous above, the abdomen and lejjs 

 more or less ferruginous, below light castaneous. Head not i)rominent, 

 the hue and genae testaceous, feebly olivaceous, and sometimes faintly 

 clouded with fuscous, the summit blackish fuscous with a distinct and 

 broad piceous postocular band; vertex gently convex, scarcely elevated 

 above the i)ronotum, the interspace between the eyes half as broad 

 again (male) or twice as broad (fe.nale) as the tirst antennal Joint; fas- 

 tigium rather steeply declivent, rather (male) or very (female) shailowly 

 sulcate; frontal costa subeqnal, a little contracted narrowly at summit, 

 especially in the male, slightly narrower than the interspace between 

 the eyes, fading Just before the clypeus, feebly sulcate at and below 

 the ocellus, jmnetate throughout; eyes of moderate size, rather promi 

 nent, particularly in the male, distinctly longer than the intraocular 

 portion of the genae; antennae dark castaneous, apically infuscated, 

 less than three fourths (male) or about two-thirds (female) as long as 

 the hind femora. Pronotum rather short, feebly enlarging i»osteriorly 

 but more rapidly on the metaz(ma, the upper portion of the lateral 

 lobes occupied by a broad piceous postocular bainl, broadening pos 

 t'jriorly and generally weaker on, but never absent from, the metizona: 

 disk broadly convex, passing by a broadly rounded shoulder nowhere 

 for'ning semblance of lateral carinae into the interiorly vertical lateral 

 lobes; median carina distinct on the metazona, blunt, equal, and 

 almost subobsolete on the i)rozona; front margin truncate or subtrun- 

 cate, hind margin very broadly convex, occasionally subangulate, the 

 angle exceedingly obtuse; prozona slightly longitudinal (male) or 

 quadrate (female), about a fourth (male) or a fifth (female) as long
