Body moderately stout, rarely slender, generally feebly compressed, 

 more or less but generally feebly pilose. Head moderately, rarely not 

 at all, prominent, generally but little if any longer than the prozona, 

 unless the latter (as rarely) is distinctly transverse; face almost verti- 

 cal or a little oblique, its angle with the fastigiuin rarely less than 75; 

 vertex gently tumid; eyes rounded oval, never more generally less than 

 half as long again as broad, the anterior margin subtruncate or feebly 

 convex, separated above rather or very narrowly, at most but little 

 farther apart than the width of the equal or subequal frontal costa; 

 fastigiuin more or less sometimes very declivent, passing insensibly into 

 the frontal costa, always more or less sulcate or with elevated lateral 

 margins, generally more deeply sulcate in the male than iu the female; 

 frontal costa moderately prominent, generally sulcate below, usually 

 more or less punctate; antennae slender, of variable length, but never 

 very short, never longer than the hind femora, and rarely if ever more 

 than twice as long as the pronotum, even when this is subtruiicate pos- 

 teriorly. Pronotum generally subcompressed, rarely or never twice as 

 long as the average breadth, generally only half as long again as the 

 average breadth even in the male, the metazona generally more or less 

 flaring, its disk plane and densely punctate, while that of the prozona
