which are conjointly, broadly rounded; humeri not prominent; 
surface with a distinct, arcuate, lateral carina reaching from 
humerus to apical margin, with rows of fine punctures, the 
sutural row widely arcuate behind the scutellum, forming a 
moderately wide smooth area, and with a rather deep, elongate 
depression along lateral margin behind the humeri. Beneath 
flattened; abdomen very finely granulate and with densely 
placed, elongate, circular marks; prosternum distinctly divided 
into two parts, the anterior part slightly bent downward, the 
front margin truncate but not distinctly elevated; intercoxal 
process flat, transverse, sides nearly parallel to posterior angles, 
which are rounded, apex truncate; mesosternum with the ante-
