C elongate, siibdepressed, black ; head (eyes and antennae excepted) 

 and thorax fulvous, the latter with two broad vittae on the disc,

 fulvous ; eyes and antennae black, the latter -with the second 

 joint rather longer than the first, remaining joints compressed, 

 scarcely dilated. Thorax scarcely longer than broad ; sides nearly 

 straight behind, obtusely angled at their middle, sinuate and 

 narrowed in. front, anterior angle subacute, armed immediately 

 behind the angle itself with a minute tooth, the posterior angle 

 also armed with two small acute teeth ; apical margin slightly 

 convex ; above subconvex, indistinctly depressed transversely 

 behind the middle, basal margin grooved; siirface distinctly 

 but not very closely punctiu'ed ; fulvous, a short stripe near 

 the lateral borders, and two broad \itt8e on the disc, confluent 

 at the base and apex, and separated only by a narrow fulvous Hne, 

 black. ScuteUiim black. Elytra broader than the base of the 

 thorax, subparallel, dilated beliind ; sides with their outer margin 

 dilated, gradually increasing in width towards their apex, rounded 

 near the posterior angles, the latter armed with an acute tooth ;
