length; seventh about equal to the fourth, incrassate, and, con- 
jointly with the four terminal joints, forming a slender fusiform 
club; sutural lines between the last four obsolete. Thorax 
one-half broader than long, sides rounded and narrowed towards 
the apex, nearly straight and parallel at the base, above trans- 
versely convex, flattened and transversely depressed on the 
hinder disk, coarsely punctured, the punctures subrugose on the 
sides, more distant on the disk; basal lobe depressed. Scutel- 
lum oblique at the base, its apical half horizontal, its apex 
obtuse. Elytra much broader than the thorax, the shoulders 
obliquely rounded, lateral border narrow, serrate, interspace 
between the second and third costz broad, impressed with three 
or more somewhat confused rows of punctures; on the hinder 
half of its surface is seen an indistinct ridge, which unites with 
the third costa just before its apex.
