THE CANADIAN ENTOMOLOGIST. 189 



Body black, glossy, thickly punctured, the punctures on the upper- 

 surface being most conspicuous. Head circumscribed ; antennae and 

 palpi nearly of a mahogany colour ; mandibles longer than the head ; nose 

 slightly impressed : prothorax with two furrows at the lateral margin, both 

 nearly reaching the base, the inner one, as usual, when arrived at the 

 anterior margin, with the corresponding one on the other side forming one 

 furrow surrounding the prothorax on three sides ; just above the scutellum 

 is a punctiform impression : the elytra, including the submarginal one, 

 have seven distinct furrows, the two next the suture being anteriorly 

 abbreviated and very short, especially the first ; from the base of the first, 

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

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

 apex of the elytra are bent towards the suture : cubit piceous, armed with 

 five teeth, the three outer ones obtuse. [Taken at Grimsby, Ont., by Mr. 

 Pettit.]

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 are 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 the latter, for the most minute 

 species are to be found in Southern India, where they abound, while the 

 largest seem to inhabit temparate climates. 



$ Body entirely black, except the hands or anterior tarsi, which are 

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

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

 transverse ridges : the prothorax is rough 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 space 

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

 sharpish teeth. 



The female differs from the male merely 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 prothoracic horn, which
