outwards. The clypeal process short and pentagonal. The 

 mandibles are not very long. The pronotum is closely 

 punctured in the middle and finely rugose at the sides. The 

 front angles are produced, not very sharp, the sides nearly 

 straight to the rounded lateral angles and then almost straight 

 to the well-marked hind angles. The scutellum is rugosely 

 punctured and closely hairy. The elytra are very finely and 

 closely punctured, rather shining dorsally but a little less so 

 at the sides. There is a short laminar process beneath the 

 front tibia near the point of insertion of the tarsus and the 

 hind tibia ends in three sharp points. 



Variation of the male. In a very small male the head is not 

 wider than the thorax, the mandibles are short, slightly curved, 

 and have only a single internal tooth situated towards the end. 

 In larger examples this tooth is preceded and followed by 

 smaller teeth and the tip is laterally compressed and bifurcated. 

 There is also a stout basal tooth beneath the mandible. The 

 largest specimens have the mandibles broad, strongly rounded 

 in the basal half, with the post-median tooth broad at tlie base 

 and closely preceded and followed by two or sometimes three 

 small teeth. The head is very broad and the anterior ridge is 

 elevated in the middle.

Pitchy brown, with the elytra, femora, tibiae and abdominal 

 sternites red, all with dark margins, those of the elytra rather 

 narrow and not well defined. The body clothed al)ove and 

 beneath with reddish hair, very short upon the upper surface 

 and very scanty upon the elytra, except at the outer margin. 

 The elytra very minutely punctured, densely at the sides, 

 where they are subopaque, but moderately shining upon the 

 inner ]jart. The antemial club fairly long, the 7th joint 

 almost as long as the last three. 



9- The head is densely and coarsely rugose, witli the front 

 angles sharp, but not jiroduced. The pronotton is closely 

 ])unctured, very strongly, except in tlie middle, where the 

 ])unctures are not very fine. The sides are ratlier sharply 

 angular in the middle and the front and hind angles are well
