scales from about the middle to near the apex. Prothorax feebly carinate, and sparsely, irregularly 
punctate, each puncture bordered externally or posteriorly by a smooth crescentiform elevation. Elytra 
broadly depressed along the suture to about the middle, seriate-punctate, the interstices granulate, 
3 and 5 interruptedly raised. Anterior tibie serrulate within, and bowed at the apex, in the ¢.
