in front, densely and finely graniilose behind, the rather deep 

 channel between the antenniferous tubercles sparsely punctured. 

 Antennae reach to the apical third of the elytra ; first joint 

 rather stout, twice as long as broad, strong]}' but sparsely 

 punctured, third thick, flattened or slightly channelled above, 

 equal in length to the fourth, fifth, and half of the sixth ; sparsely 

 punctured, somewhat asperate beneath. Prothorax with its lateral 

 edges sharply spined, convei'ging in nearly straight lines towards 

 the apex ; the notum rather strongly deflexed at the sides, flattened 

 in the middle and marked with a few shallow depressions, a 

 small median space smooth and glossy, the rest of the surface 

 coarsely punctured, more densely so towards the sides. Scutellum 

 dull, sparsely punctured. Elytra parallel-sided, scarcely wider 

 than the base of the prothorax, finely granulate at the shoulders 

 and near the scutellum, rugulose over the rest of their surface. 

 Legs somewhat spinous beneath, the middle and hind femora 

 slightly asperate above, the front femora very rough ; first joint 

 of tarsi not so long as the next two united. Prosternal process 

 coarsely and not very closely punctured ; mesosternum pubescent, 

 deeply impressed on each side ; metasternum finely punctured, 

 somewhat more thickly so at the sides than in the middle. 

 Abdomen slightly glossy, finely but not very closely punctured. 



Length 55-70 mm.

II. Protliorax above and helovj, mesostermim and sides of metasternum 

 in the male ver>j closely ininctured and dull, but ivith a 

 transverse band at the base of the pronotum and certain 

 rather well-defined areas on the disc sparsely ininctured and 

 glossy (Prinobius). 



A. First joint of antenna' one-third longer than its tvidth.

(S . Dark brown, with the elytra of a somewhat lighter brown 

 tint that becomes darker towards the base ; the intermediate joints- 

 of the antennae, the hind legs and the tarsi moi-e or less reddish. 

 Head somewhat strongly punctured in front and between the 

 eyes, finely granulose behind. Antennte reach to the apical 

 third or fourth of the elytra : first joint relatively short, only 

 about one-third longer than broad, coarsely punctured ; third 

 thickened, slightly channelled and sparsely punctured above, some- 

 what denticulate below, equal in lengtli to the fourth, fifth, and 

 nearly half of the sixth united. Prothorax with its sides converging 

 in slightly curved lines in front ; the disc with two triangular, 

 strongly punctured and slightly depressed, nitid areas in front, 

 two small rugose spots external to these and a trausversc nitid
