 prothorax still more hexagonal in the male, less cordate in the 

 female, broadly depressed in the centre, and with a broad longi- 

 tudinal greyish white pubescent band ; elytra as in the two pre- 

 ceding species, but with six continuous costse reaching from the base 

 to four-fifths of the length, intervals alveolate, the alveolae with a 

 fulvous pubescence, a greyish, short, sutural basal band, and the 

 smooth posterior part and also the lateral outer margins with a 

 sparse greyish pubescence. Length 26-33 mm. ; width 8-11 mm.

 a reddish spot on the vertex ; prothorax as broad as long, cordiform, 

 with scattered punctures, narrowly depressed longitudinally in the 

 centre, and with a very fine median groove ; elytra smooth, shining, 

 elongated, with the anterior angle much sloping, the lateral sides 

 straight, and the posterior angles sloping, not truncate, subdepressed,
