Gen. DEEPANOCHIRUS, n. gen. 



Buccal organs of Drepanocerus and Oniticellus, but the mentum 

 is very deeply and broadly furrowed longitudinally in the centre ; 

 head transverse, clypeus very little attenuate in front, eyes lateral 

 not showing at all on the upper side; antennae eight-jointed; pro thorax 

 plane, nearly parallel, and without any lateral round impression ; 

 scutellum elongate, narrow ; elytra parallel, plane, and without 

 epipleura; pygidium plane, vertical; anterior femora very dilated, 

 compressed, and with the anterior margin sharply laminate ; anterior 

 tibi^ quadri-dentate externally, the teeth strong, and not set close to 

 one another ; in the male they are prolonged inw^ardly in a falciform 

 mucro ; intermediate and posterior tarsi long, slender, and with the 

 basal joints slightly arcuate at base, a little longer than the three 

 following, and not thickened ; prosternum sharply carinate ; meso- 

 sternum invisible, metasternum nearly plane but slightly carinate 

 longitudinally in the centre. 



This genus is created for Oniticellus cunhiguus. The sculpture 

 of the prothorax, elytra, and pygidium approximates to that of 

 Drepanocerus from W'hich it is readily separated by the eyes which 

 are not visible on the upper side, and the presence of a scutellum. 

 The sheaths of the penis of the male are similar in shape to those 

 of Oniticellus.

Black, covered with a chocolate colour squamose tomentum ; head 

 with the clypeus dipping at apex, slightly emarginate, the angles of 

 the emargination are sharp and even recurved in the female, and 

 there are two small lateral teeth next to the genae, the surface is 

 divided in five moderately broad areas by carinate, squamose ridges ; 

 prothorax nearly parallel, a little declivous at apex, plane, and 

 divided in eighteen areas by squamose reticulate caringe, there is no 

 lateral puncture or round impression, and the areas are very deeply 

 and closely punctured ; scutellum narrow, sub-parallel and aculeate 

 at tip ; elytra parallel, plane, with the humeral callus w^ell developed 

 and quite lateral, truncate at apex, broadly striate, the striae dis- 

 tinctly foveolate, and the intervals plane except the suture which is 

 raised, and the fourth and seventh intervals which are sharply carinate 

 and setulose, at apex the setae become fasciculate on the suture.
