summit. The pvotliorax is elevated into a dorsal hump 

 produced bluntly forwards and very minutely notched in 

 front. 



? . There are two carinse on the head, but none on the 

 pronotum. 



This is exceedingly like the first-described species, but a 

 little smaller, relatively narrower, and more finely punctured. 

 Tlie cephalic carina of the male is not toothed in the middle 

 and the thoracic hump is narrower and scarcely bituberculate 

 in front. 



Oniticellus modestus, sp. n. 



Fusco-ferrugineus, opacuss, metasterni medio pedibusque sat nitidis ; 

 capita cupreo-nigro prothoracisque medio fusco, nonnunquam 

 vage cupreo : sat elongatus, depressus, toto inermis ; capite 

 emarginato, irregulariter puuctato ; prothorace densissime punc- 

 tate, postice leviter sulcato ; elytris striatis, minute granulatis, 

 apicibus pygidioque setiferis. 



2 . Clypeo paulo magis producto, tibiis anticis fortius dentatis. 



Long. 5"5-7*5 mm. ; lat. max. 3-4 mm.

Dull opaque ferruginous brown, with the legs and the 

 middle of the metasternum shining, the head slightly coppery, 

 and the prothorax vaguely darker at the middle and some- 

 times feebly metallic. The body is elongate and very flat 

 above, and there is no armature of any kind in either sex. 

 The head has intermixed coarse and fine punctures and the 

 clypeus is gently emarginate in front. The pronotum is 

 densely, and at the side rugosely, punctured, and there is a 

 lightly impressed longitudinal line at the middle of the basal 

 half. The sides and base are gently and continuously 

 rounded and the front angles very blunt. The elytra are 

 finely striated and the interstices flat and minutely granulated. 

 The elytra near the extremities and the pygidium are 

 furnished with short stiff bristles, and the metasternum is 

 strongly punctured. The front tibiae are armed with four 

 strong teeth. 



The female has the clypeus a little produced and the front 

 tibiae rather broader and more strongly toothed. 



In some of the species of Oniticellus tiie more pronounced 

 sexual characters, contrary to the general rule, are those of 

 the female sex, and certain authors have therefore described 

 the females as males. I have proved by dissection that the 

 sexes of the present species are correctly discriminated. 



This species seems to be the southern representative of the
