second joint oval, incrassate, being about half the 
length of, and of the same thickness as, the basal one ; 
the third and following ones to the tenth nearly equal in 
length, each about half as long again as the second, the 
eleventh rather longer, its apex acute. Thorax about 
half as broad again as long; sides rounded, nearly 
straight, but diverging from the base to the middle, 
anterior angle thickened, very obliquely truncate, the 
hinder one acute; disk convex, sparingly punctured ; 
basal sulcation rather shallow, slightly sinuate in the 
middle, impressed with a single row of strong punc- 
tures, rather coarser than those on the disk. Elytra 
much broader than the thorax, oblong, not depressed 
below the basilar space, the latter on each elytron 
shghtly thickened, the humeral callus prominent; sur- 
face rather strongly punctate-striate, interspaces nitidous, 
shightly but distinctly convex, more strongly thickened 
near the lateral margin, the two outer interspaces dis- 
tinctly costate; towards the apex of the elytron the 
interspaces are much flattened, nearly plane, the striz 
themselves being more finely punctured.
