Varying from dark brownish fuscous to ferrugineo- testaceous. Head 

 feebly prominent, more or less livid testaceous, above darker, sometimes 

 completely blackish fuscous, sometimes blackish fuscous in a median 

 posterior stripe, and always with a fuscous or blackish postocular baud; 

 vertex somewhat tumid, especially iu the male, raised well above the 

 level of the pronotuin, the interspace between the eyes moderate, fully 

 as broad as (male) or much broader than (female) the first antenna! 

 joint 5 fastigium strongly declivent, deeply (male) or shallowly (female) 

 sulcate throughout; frontal costa percurrent, rather broad, broader 

 than (male) or as broad as (female) the interspace between the eyes, 

 subequal but a little contracted at its upper extremity, feebly sulcate 

 about the ocellus, punctate throughout, but especially laterally ; eyes 

 pretty large, not very prominent even in the male, distinctly longer than 

 the intraocular portion of the genae; antennae about two-thirds (male) 

 or but little more than half (female) as long as the hind femora, varying 

 from luteous to ferruginous, often a little infuscated, especially apically. 

 Pronotuin feebly enlarging posteriorly, faintly constricted niesially, the 

 lateral lobes a little lighter colored than the disk, except for the broad 

 piceous band above, which extends across the prozona, occasionally a 

 little broken; front margin faintly convex, hind margin a little obtus- 

 angulate, the median cariua distinct on the metazona only, subobsolete 

 between the sulcij lateral carinae feebly indicated in the abrupt but 

 rounded angle by which the disk passes into the lateral lobes ; prozoua 

 quadrate or longitudinally subquadrate in both sexes, but little or 

 no longer than the faintly punctate metazona. Prosternal spine not 

 very long, moderately stout, cylindrical, blunt, erect, a little shorter 

 and a little appressed in the female; interspace between mesosternal 

 lobes much more than twice (male) or slightly (female) longer than
