side. The canthus is abruptly produced outward in the 

 anterior part of the head, forming a strong horizontal lobe, 

 rounded in front and bluntly angular behind. The mandibles 

 bear strong erect processes, curving towards each other at the 

 apex and strongly lobed behind at the base. The pronotum is 

 short and lias a closely punctured front marginal band in its 

 median part and a strongly pvmctured narrow median gi'oove. 

 The sides are very broadly, strongly and closely punctured, and 

 the space between the punctured area and the median groove 

 is very minutely and sparsely punctured. The sides and base 

 are strongly margined, the anterior part of the lateral margin 

 for rather less than half the length rather abruptly dilated and 

 thickened, the posterior part nearly straight, the front angles 

 very obtuse, the hind angles broadly rounded and the base 

 gently curved. The elytra are very short and bear strongly 

 elevated narrow shining costse, with the intervals closely 

 punctured, each containing a chain of rather large contiguous 

 pits and a series of smaller and less regular punctures on each 

 side. The apices are coarsely and closely pitted and opaque. 

 The lower siu'face of the body is densely punctured or rugose, 

 except parts of the head, the mentum very coarsely rugosely 

 punctured, the metasternum coarsely rugose at the sides and 

 strongly punctured in the middle, the abdomen rugosely 

 punctured, except the last sternite, wliich is more finely 

 punctured.

Black and shining above and beneath, the body ejdindrical 

 and convex, not very elongate. The head is very broad, 

 depressed in the middle, strongly and evenly punctured, very 

 smooth and shining in front. The cantlius is strongly and 

 evenly rounded, broadest behind, where it forms a rounded 

 lobe. The mandibular process is very strongly curved inwards 

 and broadly lobed at the base behind. The j)ronotiim is broad 

 and smTounded by a marginal groove, deejjcst on each side of 

 the trisinuate front margui. There is a median tubercle a little 

 behind the front margin and a deep short oval depression, 

 containing scattered punctures, behind it, not reaching the 

 tubercle or the base. There is also a small deep roundish
