140 Mr. D. Sharp on some JVitidulidce, i§'c. 



the widtli behind the middle is very little diminished ; it 

 is ample at the sides, so that the expanded part there is 

 rather conspicuous, especially near the hind angles ; the 

 punctuation is sparing and rather coarse. The punctua- 

 tion of the thorax is similar to that of the elytra but is 

 scarcely so distinct. 



The species is rather closely allied to IJaptoncus tetra- 

 gonus, but is slightly broader; it is unspotted; the thorax 

 is more ample at the sides, and its punctuation is coarser 

 and more distant. It is extremely similar to the speci- 

 mens of Haptoncus testaceus (Murray) in the British 

 Museum, from Macassar, but is, I think, certainly distinct 

 on accovmt of the more explanate sides of the thorax. 



I have received four specimens from Mr. Blackburn. 

 I think they are all females.
