Length 8 lines. 

 Black, opaque, densely, squamose. Head punctate, bitubercu- 

 late and clothed beneath with red haii\ Thorax transverse, 

 punctate, and interruptedly six-costate, — the costa on each side 

 of the median line diverging in the middle and not reaching the 

 base, the next entire, close to the last and merging in it in the 

 middle, and the third near the posterior angles, thick, interrupted, 

 and not extending to the apex — with the lateral margin trituber- 

 culate, one tubercle at the posterior angles, the other two forming 

 sinuations on the sides behind the anterior angles. Scutellum 

 lanciform. Elytra much broader than the thorax, acute at the 

 humeral angle, gradually widening behind, broadly rounded and 

 minutely emarginate at the apex, and roughly punctured in 

 irregular rows, with the alternate interstices furnished with large 

 elongated tubercles, and with the first of these alternate inter- 

 stices costate at the base. Fore tibise unarmed.

 Black, densely punctate and lightly squamose. Head bitu-

 in the middle, those next to them being more distant and quite 

 interrupted in the middle, and the two tubercular sinuations of 

 the anterior part of the lateral margin being much more slight. 

 Elytra very roughly and coarsely punctured in rows, with small 

 elongated tubercles on the interstices, the tubercles on the alter- 

 nate interstices being the largest. Fore tibiae with a small tooth 

 in the middle of the external margin and a large truncate lami- 

 nated one of a reddish colour at the apex.
