Black, or piceous, broadly elongate-ovate. The head is coarsely 

 rugose, with the front bitubereulate and rather broad at the anterior 

 margin, which bears two minute tubercles placed near together. 

 The pronotum is almost iiupei'ceptibly punctured at the sides, with 

 the lateral margins broadly curved and slightly narrowed anteriorly, 

 the front angles acute and the hind angles obtuse. The scutdlum 

 is smooth. The ehjtra show a vestige of a punctured sutural stria 

 and four pairs of lines of strong punctures, the first two pairs 

 abbreviated behind ; there are a few similar punctures in the 

 intervals and the lateral and apical borders are strongly and ir- 

 regularly punctured. The propygidium is scarcely punctured and 

 the stridulating files are rather distant and very finely sculptured. 

 The pygidium is finely and densely punctured, except towards the 

 apex. The front tibia is furnished with three strong acute 

 teeth and supplementary denticles. 



(S . The front tarsus is slightly thickened and the inner claw 

 very short, thick and strongly curved, with a strong basal lobe. 



The species resembles II. punctolineat^is., Fairm., but the 

 marginal tubercles of the clypeus are placed closer together, the 

 pronotum is less visibly punctured, the stridulating files are finer 

 and farther apart, and the pygidium is more finely and closely 

 punctured.

268 Heteronychus robustus, sp. n. 



Black or piceous, reddish beneath, smooth and shining, and 

 broadly elongate-ovate in shape. The head is coarsely rugose, 

 with two tubercles at the middle, and the clypeus bidentate. 

 The pronotum is broad, scarcely narrowed in front, with the 

 side margins strongly rounded and the hind angles broadly 

 rounded off. The scutellian is smooth, and the elytra have a broad 

 smooth strip bordering the suture and rather feeble longitu- 

 dinal rows of punctures externally, the punctures being obsolete 

 at the middle of the outer margin and strong and irregular at the 

 apical angles. The propygidium is finely punctured and pro- 

 vided with two narrow stridulating files, and the pygidium is
