Black, covered (except a longitudinal glabrous spot on the 

 middle of the protliorax and a few glabrous spots on each 

 elytron) with a pale ashy pubescence, which is of a darker 

 shade and glossy on the legs and underside of the body. 

 Epistoma and palpi piceous ; labrum and mandibles black. 

 Face with a few minute scattered punctures and with a median 

 impressed line extending from the clypeus to the occiput. 



Anterior margin of the pronotum somewhat angularly pro- 

 duced ; lateral tubercles of the thorax directed outwards and 

 upwards, the two dorsal tubercles obtuse and but little raised ; 

 between the latter is a median, glossy black, spatulate spot. 

 The punctures on the thorax are not uniformly distributed — 

 a few on the anterior border on each side of the middle line, 

 a few behind each of the dorsal tubercles, and a fevv on the 

 posterior part of each lateral tubercle. 



Elytra minutely punctured, punctures scarcely visible 

 through the pubescence, except at the base and sides. With 

 two or three rows of widely separated asperate punctures on 

 each elytron ; two of these rows are along the faint ridges 

 which bound off the median sloping area from the flattened 

 area of the disk on the one side and from the vertical mar- 

 ginal area on the other. There are three or four irregular 

 glossy black spots on the disk of each, and a few small 

 glossy granules on each near the base. 



Antennae with the ajucal third of the third joint and the 

 apical half of each succeeding joint of a dark brown colour ; 

 the first and second joints and the remaining parts of the other 

 joints pale ashy.
