A single specimen of the female taken in the Journey from New York to Cum- 

 berland-house. I have also a specimen of the male taken in New England, by the 

 late Professor Peck. The larger female was taken, I believe, in the province of 

 Massachusets, by Mr. Drake. 



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 temperate climates. 



DESCRIPTION. 



(J 



Body entirely black, except the hands or anterior tarsi, which are rufous : gloss obscured by 

 hairs. Nose at the apex bent upwards, forming a vertical, triangular, acute tooth ; on the vertex 

 are two obsolete transverse ridges : the prothorax is rough with little granules, and anteriorly sends 

 forth a longish wide horn truncated at the end and overhanging 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 is re- 

 placed by a transverse emarginate ridge in the middle.
