 fuscous hairs ; elytra sub-opaque, and, like the hind- body, densely 

 clothed with depressed ash-coloured hairs. 



Head large, quadrate, front of forehead obliquely emarginated ; 

 broadly concave from the front to the middle, this cavity bifoveolate ; 

 vertex very densely and minutely granulated, its sides and hind 

 angles, and to a less extent the back part also, with many round 

 depressions having in each a puncture with raised margins ; man- 

 dibles robust, not much arched, pitchy-red. Terminal joint of 

 maxillary palpi usually red. Antennce (except the three shining, 

 rufo-piceous, basal joints) opaque and densely pubescent. Thorax 

 rather longer than broad, rounded and broadest near the front, 

 widely sinuously narrowed backwards ; with a row of moderately 

 large punctures not reaching base nor apex down each side of the 

 middle, a smaller series on each side, and another short row near 

 the front angle. Scutellum and elytra densely sculptured, the 

 apices of these latter obliquely rounded towards the suture ; they 

 are longer than broad. Hind -bod >j narrower than the elytra, finely 

 and densely sculptured. Legs moderate, tibiae setose externally, 

 the four basal joints of the front tarsi dilated and pilose. Underside 

 blackish, densely covered with small cinereous hairs ; fourth, fifth, 

 and sixth abdominal segments bipunctate.
