setigerous puncture at about one-third of the length, and another 

 above the constricted parts ; mesothorax pedunculate ; elytra ovate,, 

 convex ; prosternum v^ith a broad median groove ; legs moderately 

 long, the femora claviform ; the outer apical spur of the tibiae is 

 absent, and the inner ones are small, the anterior tibiae are a little 

 curved, very deeply incised internally, the intermediate and posterior 

 ones broaden towards the apex ; anterior and intermediate tarsi 

 dilated, cordiform, hairy and almost spongy underneath, those of the 

 hind-legs elongate. 



This genus occurs in Africa (Senegambia, East and West Central 

 Africa) and India.

DisPH^Ricus EBENiNus, Chaud., 

 Berl. Ent. Zeit., 1861, p. 131. 



Black, smooth, very shining ; palpi, legs, and antennae rufescent ; 

 head v^ith two oblique, long, narrow impressions, and divided from 

 the neck by a transverse, narrow groove ; prothorax subglobose, a 

 little broader behind than in front, slightly depressed on the median 

 part which is distinctly grooved longitudinally ; elytra ovate, not 

 broader at the base than the peduncle, convex, but depressed along 

 the suture which has on each side a narrow, deep stria filled with 

 deep, round punctures, and reaches from a short distance from the 

 base to the apex ; at a short distance from the base and not quite in 

 a line with the juxta-marginal stria there is a deep, conspicuous 

 puncture, while the outer margin has also a series of deep punctures, 

 interrupted in the median part, and broader and deeper in the 

 posterior than in the anterior part ; the three last segments of the 

 abdomen have a transverse series of closely-set, deep punctures^ 

 setigerous on the last segment only. Length 8 mm. ; width 3 mm.

DisPH^mcus xATALENsis, Wcstwood, 

 Proc. Entom. Soc. Lond., 1864, p. 3. 



Colour and sculpture of the preceding species, but the prothorax 

 is more parallel laterally and slightly narrower above the constriction 

 than in the anterior part, and a little more elongate in the male than 

 in the female ; the juxta-sutural stria is, if anything, more deeply 

 punctured in the anterior part than in D. cheninus, and does not 

 reach quite so far down the apex, the intra-marginal punctures are
