^ . Head not broader than long, impressed with a median 

 groove ; clypeus slightly depressed, flat, emarginate in front, 

 bounded behind by two oblique or slightly curved grooves that 

 diverge from the end of the median groove ; eyes rather large, very 

 slightly emarginate in front ; mandibles vertical, stout, relatively 

 short, convex in front, each armed with one or two strong teeth 

 on the inner side. Antennae shorter than the body, 11-jointed ; 

 first joint longer and much thicker than the third ; third longer 

 and thicker than the fourth ; fourth to tenth subequal in length. 

 Pronotum transverse, somewhat unevenly convex, denticulate or 

 spinose along each side ; the upper surface for the most part very 

 closely punctulate and dull, but with two or more sparsely punc- 

 tulate, nitid or subnitid spaces near the middle and a narrow 

 tranverse strip of the same kind near the base. Scutellum very 

 closely punctulate. Elytra twice as long as broad or longer, rounded 

 or subtruncate at the apex. Body beneath very closely punc- 

 tulate, more or less dull, but with a median triangular area 

 of the metasternum, and the hind borders of the first four 

 abdominal segments nitid, sparsely or not at all punctulate. 

 Intercoxale of the prosternum horizontal behind, obtusely pointed 

 at the apex. Last ventral segment truncate or slightly sinuate at 

 the apex. Legs long and rather thick ; femora parallel-sided, 

 denticulate or spinose along their ventral edges ; tibiae compressed, 

 more or less spinose along the edges ; tarsi broad, with the first 

 joint of the front tarsus scarcely longer than the second, that of 

 the hind tarsus not so long as the second and third united. 



$ . Antennae shorter ; pronotum with its eides converging more 

 in front, and more strongly denticulate or spinose, its disk sparsely 

 punctulate and more or less shiny all over, not exhibiting definite 

 smooth spaces ; body beneath less closely punctulate and more 

 glossy than in the male.
