joint flavate; prothorax rather small, not quite one-half wider than 

 long; base but slightly narrower than the apex, widest before the

 flexed throughout; obtuse basal angles without prominent apex and 

 very abruptly though moderately reflexed, the puncture on the edge 

 unusually small; subbasal impression feebly subangulate; elytra 

 nearly three-fifths longer than wide, fully one-half wider than the 

 prothorax and subparallel, with arcuate sides and distinct humeri; 

 first and second striae feebly impressed but distinct, the others sub- 

 obsolete, except under oblique reflection; anterior fovea at two-

moderately convex, ventricose, the anterior parts relatively 

 small, shining, with feeble sericeous lustre, the micro-strigilation of 

 the elytra extremely fine and close; color very dark and uniform 

 castaneous throughout above; under surface rufo-piceous, the legs 

 flavate; head three-fourths as wide as the prothorax, the eyes rather 

 large, prominent, the sulci deep; antennae long and slender, black- 

 ish, the first three or four joints flavate, the second much longer 

 than either the first or third; prothorax rather less than one-half 

 wider than long, slightly narrower at base than at apex, the sides 

 rounded, finely reflexed, oblique and becoming very slightly sinuate 

 in about basal half, the angles obtuse, moderately reflexed; sides of 

 the base very oblique; subbasal impression deep; a rather deep elon- 

 gate impression near each side of the base is evident; elytra barely 

 one-half longer than wide, fully two-thirds wider than the prothorax, 

 slightly wider behind the middle than at base; first stria rather deep 

 and broad, the second much feebler, the others indistinct or wanting;

 two-thirds as wide as the prothorax, the eyes moderate in size, rather 

 prominent, the sulci deep, parallel; antennae piceous, gradually pale 

 basally, as long as the elytra, the second joint as long as the first,

 distinctly narrower than the apex; sides rounded, oblique and straight 

 posteriorly, the angles obtuse and slightly blunt; subbasal impression 

 moderate, feebly angulate; elytra barely one-half longer than wide, 

 not quite one-half wider than the prothorax, subparallel, with arcu-
