neck. Antennae short, more or less robust, almost straight, distinctly 

 thickened externally, first joint strongly incrassate, very shortly oval, 

 second slightly less incrassate, stouter than the third, the latter ob- 

 conic or elongate conic, the following submoniliform, the outer joints 

 more or less transverse, the last very shortly oval. 



Prothorax oblong or suboblong, subattenuate in front, slightly 

 rounded at apex, truncate at base, subangulate-dilate on the sides 

 before the middle, scarcely narrowed or somewhat narrowed behind, 

 very much narrower than the elytra, very finely margined at base 

 and on the sides. Epipleurse large, visible at the sides, rather narrow 

 in front, dilated and rounded behind. 



Scutellum rather small, subogival. 



Elytra rather large, suboblong, a little longer than the breast, 

 longer than the thorax, truncate at apex, broadly rounded at the 

 postero-external angles, subrectilinear and distinctly margined at the 

 sides, more finely at apex. Epipleuras rather strongly inflexed, sub- 

 arcuate, acute posteriorly. Shoulders prominent. 



Prosternum rather strongly developed before the anterior coxae, 

 angulate. and submucronate posteriorly. Mesosternum moderate, 

 subacute behind, the prolongation hardly reaching the middle of the 

 intermediate coxa;. Mesepisternum rather large, separated from the 

 mesosternum by an obsolete margin. Mesepimera moderate, oblong, 

 oblique. Metasternum rather large, not sinuate at the insertion of 

 the posterior coxae, feebly angulate between them, angulate between 

 the intermediate coxae and linearly prolonged to the point of the

 cealed. 



Abdomen rather short, shorter than the elytra, large, subacumi- 

 nate posteriorly, side margins broad and elevated, more or less cov- 

 ered at base, segments subequal, the sixth rather well developed, the 

 armature (J*) sometimes apparent. The sixth ventral rather well 

 developed, the seventh sometimes very distinct. 



Anterior coxse moderate, shorter than the femora, projecting, 

 conic, subcontiguous. The intermediate almost as large, scarcely 

 projecting, conic-suboval, slightly distant. The posterior rather large, 

 subcontiguous within, upper lamella transverse, narrow exteriorly, 

 suddenly dilated interiorly, lower lamella rather narrow subvertical.
