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 costa3 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.

Head moderately produced between the eyes ; vertex granu-

 antennae moderately robust, slightly thickened towards their 

 apex ; all the joints distinct, two basal joints equal, cylindrical, 

 the first thickened, third elongate, fourth and fifth each scarcely 

 longer than the second, equal, sixth distinctly shorter than the

 shorter than the seventh, also equal, the apical joint rather 

 longer, acute. Thorax one-third broader at its base than long, 

 sides rounded, nearly straight behind, narrowed and sinuate in 

 front, anterior angles armed with a short obtuse tooth ; above 

 subcylindrical, transversely excavated near the base, coarsely 

 punctured ; fulvous yellow, a broad vitta down the middle, to- 

 gether with the lateral border, black ; basal lobe short, deeply 

 depressed. Scutellum shining black, curved, triangular, its 

 apex obtuse. Elytra much broader than the thorax, slightly 

 increasing in width towards their apex; sides narrowly mar-
