Body elongate, tubercles of the alternate rows 

 broadly separated ; apical teeth of anterior tibia 

 obliquely truncate, second much rounded . . . . tuberosus. 



Body inflated, tubercles of the alternate rows not 

 broadly separated; the three teeth of the anterior 

 tibiae very sharp i^onderosus. 



h~. Alternate rows on elytra sub-costato-tuberculate, but 

 alternate ones formed by slightly larger tubercles. 



Elytra elongate, sub-parallel, prosternum trans- 

 versely nodose, teeth of anterior tibiae sharp . . asperulatus. 



Elytra moderately elongate ; prosternum aculeate ; 

 the two apical teeth of anterior tarsi divided by a 

 small emargination, second tooth rounded . . . . radula. 



Elytra nearly parallel, rows of tubercles more costate 



laterally, prosternal process sharp damarinus. 



c. Elytra very broad, very little longer than wide. 



Elytra with alternate rows of tubercurated costse of 



nearly equal height gravidus. 



Elytra with rows of deep foveae foveatus.

Black, opaque, head and prothorax clothed with a greyish or 

 slightly flavescent coating, which is also discernible on the costae 

 of the elytra ; clypeus sharply triangular, head closely pitted and 

 having two transverse parallel caringe intersected by a longitudinal 

 median one reaching nearly to the sharp apex of the clypeus, the 

 upper transverse carina has a tendency to be separated in the centre 

 in most examples ; basal joint of antennae somewhat rufescent, 

 intermediate joints reddish, club greyish or sub-flavescent; prothorax 

 with two elongate impressions with raised Avails in the centre, the 

 anterior one of which is sub-parallel, while the posterior is elongato- 

 ovate, and having on each side a smaller anterior impression close to 

 the median one, and a longer and sub-oblique one beginning near the 

 base and extending almost to the apex, giving thus to the median 

 discoidal part a much raised appearance ; the sides of the prothorax 

 are not arcuate, only a little rounded in the anterior part, deeply 

 incised above the basal angle, not serrulate, and fringed laterally and 

 also along the base with short, ciliate hairs ; scutellum short, a little 

 cordiform ; elytra elongate, distinctly sinuate laterally below the
