of the elytra broadly and very densely ixiiutiiicd and ()j)aque. 

 The body rather narrowly elonj^atc, parallel-sided and convex; 

 the sides of the elytra almost straiLjht and the shoulders not 

 sharply angular. Tlu^ oeular eanthus reaching the middle of 

 the eye. The middle tibia bearinu a stronij lateral s})ine and 

 the hind tibia a feebler one. 



$. The head bears a [)air of transversely plaeed tubercles ; it 

 is a little hollowed and rather Hnely and closely punctured in 

 front of these and less finely and more irregularly punctured 

 behind them. The posterior part is smooth and shining and 

 the sides are closely rugose. The pronofion is very smooth and 

 shining, except at the lateral margins, where it is rugo.sely 

 jnmetured. The front angles ai-e bluntly jjrodueed, the sides 

 gently rounded to the lateral angle and from there abruptly 

 contracted to the base. 



(^. The head is short, almost as wide as the ])ron()tum, the 

 lateral angles are sharp but not produced and the sides are 

 contracted behind the eyes. The entire upper surface is 

 unpunctured and very smooth. The mandibles are far a])art 

 at the base, flat, gently curved externally, with a short, broad, 

 two-pointed interior lobe situated nearer the tijj than the 

 base. The pronotum is short and broad, its lateral angles 

 rather sharp.

Type in the British Museum. 



This is closely related to two species of South-western China, 

 D. sinensis Boil, and D. semenoioi Jakowl., but the lateral 

 angulation of the ])r(motum is sharper in both sexes, the ante- 

 ocular angle of the head in the male is sharp, the front angle of 

 the pronotum is blunt and not produced and the sides are evenly 

 curved to the lateral angle. In the female the sides of the 

 pronotum are more rugose than in the related species. The 

 mandibles of the male are relatively broader and the narrow 

 inner branch found in the related sjiecies is replaced by a broad 

 dilatation at the same point.
