Elytra at base about e(iual in wiilth to the head ; sides ratlicr feebly ilivegiMit posteriorly, slightly longer than the width at base, rather strongly arcuate, more strongly so ])osteriorly ; together broadly, roundly, and rather strongly emarginate behind ; suture nearly one-fourth longer than the pronotum ; surface convex, slightly impressed on the suture toward the base, closely, nearly evenly, rather linely, and very deeply ]iunitate; intei'si)aces narrower than the punctures, very convex, jiolished.
