Head closely and rather finely imnctured, the frontal tubercles very small, 

 labrum black, antennae not extending to the middle of the elytra, fulvous, the third 

 and fourth joints thinner than the following ones, equal, terniiual joints thickened ; 

 thorax twice as broad as long, the sides straight, the anterior angles oblique, the 

 surface crowded with strong iiunctures, the base with a very narrow and sometimes 

 obsolete transverse groove, which is bounded at the sides by a small perpendicular 

 notch, the basal margin scarcely prominent at the middle ; scutellum small ; elytra 

 with a very shallow depression below the base, only visible in certain lights, of 

 elongate and posteriorly pointed shape, the surface moderately convex, strongly and 

 regularly punctate-striate, the punctures scarcely smaller than the space dinding 

 them, the interstices longitudinally costate, especially so at the sides and apex, at the 

 latter place the punctures disajipear entirely, and only deep striae are visilile, under- 

 side blackish, femora jjiceous, tibiae more or less fulvous, the posterior ones rather 

 obsoletely notched ; prosternum strongly mgose-punctate.

The costate elytral interstices and the impressions on the thorax principally 

 distinguish this species.

 labrum black, antennae black, the lower four joints fulvous, the third joint more 

 slender than either the second or fourth, terminal joints distinctly thickened, 

 extending only below the base of the elytra ; thorax twice as broad as long, convex, 

 the sides scarcely rounded, the anterior angles oblique, forming a distinct tooth 

 before the middle, the surface with a deep transverse sinuate sulcus, bounded at the 

 sides by a peqiendicular groove, the space beliind the sulcus stained with fu.^cous, 

 rest of the surface impuuctate ; scutelhmi black ; elytra wider at the base than the

 the interstices also closely and very minutely punctate ; underside and legs black,
