converging to the apex; anterior border angulate-emarginate ; 

 antennae, labrum and jaws black. Thorax about half as broad again 

 as long; sides slightly rounded, siibparallel at the base, slightly 

 converging in front ; anterior angles produced, armed with an ob- 

 tuse tooth, hinder angles slightly produced, acute; upper surface 

 transversely convex, almost subcylindrical, finely and distinctly 

 but subremotely punctured. Scutellum as broad as long. Elytra 

 broader than the thorax, nearly parallel, scarcely narrowed to- 

 wards the apex ; surface finely punctured on the inner disk ; 

 punctures, after leaving the extreme base, arranged somewhat 

 irregularly in double rows, interspaces plane ; puncturing on the 

 outer disk stronger and irregular ; interspaces, the extreme lateral 

 surface and apex excepted, covered with raised coarse irregular 

 transverse strigae.

Head broad, front slightly convex, rather more finely punc- 

 tured than the epistome, the latter broader than long, closely 

 covered with large round punctures, its anterior border bilobate. 

 Thorax broader than long ; sides very slightly rounded, nearly 

 parallel, anterior angles produced, acute ; above subcylindrical, 

 somewhat closely covered with large ovate punctures. Scu- 

 tellum rather broader than long, sides diverging backwards, 

 apex broadly rounded. Elytra broader than the thorax, parallel, 

 slightly attenuated towards their apex, subcylindrical, coarsely 

 punctured, the punctures indistinctly arranged in irregular striae, 

 interspaces plane on the inner third of the disk, raised on the 

 outer two-thirds, and forming coarse irregular transverse strigae.
