Short ovate, very convex, eneous, very shining, the head, the prothorax anteriorly and laterally (but indeter- 
minately), and the legs and antennz, more or less rufous ; head densely punctured; prothorax transverse, 
the sides a little rounded and rapidly converging from the base and somewhat deeply grooved (especially 
at the base and apex) within the prominent lateral margins, the surface sparsely and moderately finely 
punctured, a longitudinal space in the middle of the disc impunctate ; elytra each with nine rows of rather 
fine somewhat scattered punctures placed upon very shallow strie, the punctures still finer on the middle 
of the disc, the discal interstices each with a median row of exceedingly minute scattered impressions (only 
visible under a strong lens and sometimes obsolete), the others impunctate ; beneath brownish-piceous, 
sparsely and somewhat coarsely punctured, the anterior half of the metasternum smoother; the sides of 
the prosternum and the anterior edges of the meso- and metasternum immarginate, the mesosternum 
truncate in front ; legs, including the tarsi, rather slender.
