anteriorly ; elytra very slightly rounded at the sides, seriate- 

 punctate, the punctures small and distant, the apex truncate, 

 terminating externally in a spine, black ; the base with an ashy, 

 broadly triangular band or blotch, which, however, is rounded at

 the upper oblique, the lower transverse, which meeting near the 

 suture dip down and become continuous with the other side, the 

 whole of the apical region yellowish-grey, the division of colours 

 between these markings very distinct and decided ; body beneath

Prothorax transversus, regularis ; lateribus rotundatis, iner- 



mibus. Elytra oblonga, regularia, apice extus spinosa.
