emarginate on their inner edge. Thorax twice as broad as long, sides 

 rounded, narrowed in front, anterior angles deflexed, all the angles 

 produced into a short minute tooth ; surface smooth, subremotely but 

 finely punctured on the disk, sides nearly impunctate. Scutellum semi- 

 ovate, obtuse. Elytra scarcely broader than the thorax, obovate, being 

 distinctly narrowed from the shoulders towards their apex, the apex 

 itself regularly rounded; each elytron with eleven rows of distinct, 

 deeply impressed punctures, the first abbreviated, all the others, with 

 the exception of two or three nearest the suture, nearly obliterated on 

 the apical portion of the surface ; the punctures are also much smaller 

 at the extreme base ; below the basilar space on each elytron is a large 

 indistinct shallow fovea, the surface of which is slightly irregular.

 lower edge of face deeply bilobed ; epistome nigro-piceous, irregularly 

 obcordate, its surface indistinctly concave, more deeply punctured than 

 the upper portion of the face ; antenna? slender, filiform, rather shorter 

 than the body. Thorax nearly twice as broad as long at the base, 

 sides rounded, narrowed in front, strongly deflexed at the anterior 

 angles, all the angles armed with a minute tooth ; above moderately 

 convex, impressed on either side with a small but distinct fovea ; rest of 

 the surface smooth, impunctate. Scutellum semiovate. Elytra broader 

 than the thorax, oblong, scarcely narrowed behind, apex acutely 

 rounded ; above convex, each elytron obsoletely excavated transversely 

 below the basilar space, and impressed with about eleven rows of di- 

 stinct punctures, the first abbreviated, those near the outer edge some- 

 what irregular ; all the stria? distinctly sulcate, their interspaces slightly 

 rounded. Legs fulvous, all the knees and the outer edge of the front
