Of medium size, brownish fuscous above, flavous beneath; head 

 not prominent, dark olivaceo-testaceous, sometimes plumbeous, above 

 much infuscated, with abroad piceous postocular band; vertex mod- 

 erately tumid, scarcely elevated above the pronotum, the interspace 

 between the eyes half as broad again (male) or twice as broad (female) 

 as the first antenual joint; fastigium rather steeply declivent, dis- 

 tinctly (male) or shallowly (female) sulcatej frontal costa almost per- 

 current, slightly narrowed at upper extremity, especially in the male, 

 otherwise equal, about as broad as the interspace between the eyes, 

 sulcate at and below the ocellus, punctate throughout; eyes moderately 

 large, rather prominent, particularly in the male, somewhat longer than 

 the infraocular portion of the genae; antennae testaceous or rufo testa- 

 ceous, apically infuscated, distinctly longer than (male) or three-fourths 

 as long as (female) the hind femora. Pronotum subequal, faintly 

 expanding, posteriorly, above ferrugineo testaceous, sometimes infus- 

 cated, on the sides flavous or fl a vo- testaceous below, but the upper por- 

 tion wholly occupied by a very broad, percurrent, piceous, postocular 

 band, broadening slightly on the metazona, the disk convex and pass- 

 ing by a slight shoulder into the anteriorly tumid vertical lateral lobes; 

 median carina distinct though rather slight on the metazoua and, in the 

 female at least, on the front of the prozona, elsewhere obsolete or sub- 

 obsolete; front margin faintly convex, and in the male with a scarcely 

 perceptible emargination, hind margin rotundato obtusangulate, almost 

 subtruncate; prozona distinctly (male) or faintly (female) longitudinal, 

 about half as long again as the densely but not deeply punctate meta- 

 zona. Prosternal spine short and rather stout, conical; interspace
