abbreviated and very short, especially ihe first ; t'roiu the base of the first, 

 or external discoidal one, an obsolete furrow runs obliquely towards the 

 Kubmarginal one ; the four discoidal entire furrows when arrived near the 

 apex of the elytra are bent towards the sutu.re : cubit i)iccous, armed with

The species of this little interesting genus, remarkable for the great 

 variety of processes resembling horns, that arm the head of the males, are 

 as widely dispersed as those of any genus of beetles ; they arc to be found 

 in every climate from the frigid to the torrid zone, nor do they increase in 

 size as they recede from the former and enter tlie latter, for the most minute 

 species are to be found in Southern India, v.lv.re they abound, whilf" the 

 largest seem to inhabit temparate climates. 



^ Body entirely black, except the li;>ndr. or anterior tarsi, which are 

 rufous : gloss obscured by hairs. Nose at the ape.\ bent upwards, form- 

 ing a vertical, triangular, acute tooth ; on the vertex are two obsolete 

 transverse ridges ; the prothorax is rougli with little granules, and anter- 

 iorly sends forth a longish wide horn truncated at the end and overhang- 

 ing the head : the two angles of the apex are elevated, and the spa^-c 

 between them is deSexed, and bidentate : the cubits are armed with four 

 sharpish teeth. 



The female differs from tJie male n.erely in having the shield of the 

 head more distinctly notched on each side, and the apex of the nose 

 rounded and reflexed, but without any triangular horn or tooth ; in having 

 two distinct ridges on the vertex, and in having no j)r; -.thoracic horn, which 

 is replaced by a transverse emarginate ridge in tlie middle. [Quite com- 

 mon ever)'where throughout Canada; generally found imJcr t!ie droppings 

 of horses or cattle.]

This is so like the last insect that 1 felt at first disposed to consider it 

 as merely a variety. The following diiferences in their character induce 

 me however to consider them as distinct. Not to mention the difference 

 of size, the female of O. ia/ebrosus has a distinct notch on each side of the
