antennz testaceous. Prothorax a little longer than broad, slightly 
rounded at base, basal angles obtuse, sides gently rounded to near 
apex, which is strongly rounded; surface with a slight nodose 
elevation in middle, scantily pubescent at sides and apex, its 
anterior half with concentric asperations, the posterior half shining, 
finely punctured with a groundwork of very fine parallel scratches. 
Scutellum rounded, shining, infuscate. Elytra as wide as base of 
prothorax and rather less than half as long again, base truncate, 
humeral angles subrectangular rounded, sides very feebly rounded, 
nearly parallel, apex strongly rounded, with the lateral margin 
inflexed below for a very short distance, but scarcely carinate ; 
surface shining, convex from base to posterior third, thence 
obliquely declivous, the declivity flattened and more or less 
impressed, with rows of punctures which appear large, rounded, and 
dark when strongly illuminated, interstices somewhat irregular, 
with single rows of very fine sparse punctuation and short erect 
hairs, behind middle with fine tuberculation, obliterated on the 
impressed apical area on which the strie are slightly impressed, and 
curved inwards at the tip. Underside and legs testaceous.
