Body stout, not much depressed, moderately elongate, 

 bearing short erect reddish hairs upon the head and the sides 

 of the pronotum, the middle tibia clothed with long dense hair 

 upon the upper surface. The antemial club consists of three 

 long terminal lamellse and three sliort supplementary ones. 

 The head is unsymmetrical. The supraorbital ridges are short 

 but do not extend to the front margin, the median elevation is 

 small, the frontal ridges are divergent and bear strong frontal 

 tubercles, and the imier marginal jirocesses are strong, that on 

 the left long, triangular, bluntly pointed and scarcely inclined, 

 that on the right more shortly triangular and rather sharp- 

 pointed. The pronotum is rather short, very smooth, with not 

 more than a trace of a median groove. There are fairly 

 numerous fine setigerous punctures close to the lateral edge, 

 especially in and around the lateral scar. The lateral groove 

 is very line, as well as its extension at the side of the front 

 margin. The elytra are deeply grooved, the grooves not 

 visibly punctured. The mentuni is closely punctured at the 

 sides and smooth in the middle of the base. The mesosfernnm 

 is without distinct lateral scars and the 7netasternum is only 

 very lightly punctured at the sides. 



Length, 27 to 36 mm. ; breadth, 10 to 13 mm.

Burmese representatives of the s])ecics are a little smaller 

 than those from the Himalayas, but in Assam the size is 

 variable. The name dunsiriensis was given to certain specimens 

 from Assam in whicli the mentum has a basal ridge extending
