Head smooth, face subquadrate, nearly the whole surface below the 

 antennfe covered by a large, smooth, slightly depressed triangular 

 space, boimded on the sides by a slightly raised margin, the lower 

 portion of the space traversed by a deep transverse depression, whilst 

 its apex extends upwards between the antennae, terminating immedi- 

 ately above the latter in a deep fovea; clypeus nearly obsolete, its 

 place being occupied by the thickened lower edge of the triangular 

 space ; antennae slender, pale fulvous, terminal joint in the 7)iale 

 flexuose, acute ; thorax narrowly margined, sides slightly produced and 

 roiuided in front, nan-owed and sinuate behind, anterior angles pro- 

 duced laterally into an obtuse tooth, the posterior slightly produced, 

 subacute, above moderately convex, minutely but not closely pimc- 

 tm-ed, impressed behind the middle of the disk by a broad ti-ansverse 

 groove fomied by two large transverse foveae placed side by side; 

 scutellum trigonate, its apex obtuse ; elytra oblong, much broader 

 than the thorax, convex, transversely depressed below the base, basilar 

 space on each elytron distinctly elevated, the raised portion being 

 bounded externally by a longitudinal depression within the humeral
