second, the fourth as long or nearly so as the two preceding ones 

 united, the third and fourth joints in the <? distinctly thickened. 

 Thorax one-third hroader than long, the sides parallel and slightly 

 sinuate fi-om the base to beyond the middle, thence rounded and 

 converging to the apex ; disk convex, smooth, impressed on either 

 side with a shallow fovea. Elytra narrowly oblong-ovate, slightly 

 dilated posteriorly, convex, not depressed below the basilar space, 

 finely and closely punctured ; each elytron with a sutural line 

 extending from base to apex, together with a second also entire, 

 submarginal and confluent at its extreme apex with the first.
