Body elongate, tubercles of the alternate rows 

 broadly separated ; apical teeth of anterior tibise 

 obliquely truncate, second much rounded . . . . tuhcrosus. 



Body inflated, tubercles of the alternate rows not 

 broadly separated ; the three teeth of the anterior 

 tibiae very sharp ponderosus. 



b-. 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 tibife sharp . . aspcridatus. 



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 damarimis. 



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



Elytra with alternate rows of tuberculated costae of

Monogr., Coleopt. Heft, ix., x., 1872, p. 32. 



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



slightly flavescent coating, which is also discernible on the cost* 



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



having two transverse parallel carinas 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 antennas somewhat rufescent, 



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



with two elongate impressions with raised walls 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
