curved in front and l)luntly jHoduced behind the eyes. Tlie 

 pronotuni and elytra are entirely ])unctured, the former rather 

 .si)aringly in the middle and more strongly and very densely at 

 the sides, the elytra rather closely and at the sides and apices 

 tlensely. The sides of the metaskrnnm are closely and the 

 al)domen sparsely punctured. The front tibia is rather narrow 

 and ends in a palmate ])i()cess and the middle and hind tibiae 

 have each a strong lateral spine. 



cJ. The head and j)r()notum are densely and finely granular 

 and opaque, the latter less densely in the middle. The head 

 is flat above, strongly excised in front, the front angles are 

 obtuse and the sides bear a very strong acutely angular j)r()cess 

 behind each eye. The clypeal process is tongue-like, narrow and 

 bluntly pomted. The pronotum is short, the front angles form 

 broadl}' rovmded lobes, the lateral angles are spiniform and 

 from there the sides are straight to the broadly rounded hind 

 angles. The elytra are very minutely and closely jjunctured, 

 slightly shining ujjon the inner half and dull upon the outer 

 half and the extremities. The metasternuia and abdomen are 

 opaque, except in the middle. The front tibia is slender, with 

 minute lateral teeth and the middle and hind tibiae are without 

 a lateral spine or with only a very minute one. 



Variation of the male. This no doubt is as in D. oweni. I 

 have seen only two males. In the smaller one the head is less 

 broad than in the other, the mandibles are short and broad, 

 finely and closely toothed at the inner edge, except in the basal 

 part, and there is a single short but sharp tooth beneath at a 

 short distance from the base. In the larger (type) specimen 

 the head is very broad, the mandibles are more wide ajjart at 

 the base, but still apposable in the anterior half, which is finely 

 toothed, and tlie single lower tooth is very strong, shar[) and 

 has an obliquely downward direction. The lateral edges of the 

 })rothorax are slightly concave in the middle.
