mandibles wlien viewed from above, and when the latter 

 are closed. Thorax twice as broad as long at the base, 

 broader in front ; sides diverging from the base to 

 bejond the middle, thence rounded and converging to the 

 apex; hinder angles slightly produced, acute, anterior ones 

 thickened, obtuse, somewhat recurved ; upper surface 

 transversely convex, coarsely and deeply punctured. Scu- 

 tellum trigonate, its apical angle rounded. Elytra broader 

 than the thorax, oblong-ovate, convex, each impressed 

 below the basilar space with a large shallow fovea, the 

 humeral callus slightly thickened ; surface strongly punc- 

 tate-striate, the interspaces slightly convex on the inner 

 disk, distinctly so towards the lateral margin and towards 

 the apex ; interspace next the suture impressed with deep 

 punctures as large as those on the strite themselves.
