agrees with the one above described in liaving the under sur- 

 face of the middle femora and the inner surface of the middle 

 tibije clothed with long hair, but diftcrs in the frontal excava- 

 tion being triangular, much larger and broader, the prothorax 

 much more strongly punctured, and especially by the elytral 

 stria3 being very fine, the outer ones obsolete, and the intervals 

 perfectly tlat and coarsely ])unctured. The tooth of the man- 

 dibles rises nearly perpendicularly about one-third from the 

 tip ; the angle is nearly rectangular, and the upper edge nearly 

 horizontal, extending nearly to the base, giving the appear- 

 ance of a curved inner outline and great breadth to the hind 

 part of the mandible. 



These characters seem to indicate a distinct species, to which 

 I would give the name of C. jyunctatus. 



ODONTiEUS. 

 Odontceus obesus, Lee. 



One well-developed male (10 millims. long). On account 

 of the resemblance of sculpture, I refer it to this species, of 

 which the female only was previously known to me by a single 

 Californian specimen. The clypeus is more obtusely rounded 

 in front than in the two species of Eastern America, filicornis 

 and cornigerus, and somewhat less coarsely punctured ; the 

 horn is long and slender, as in them ; the prothorax is similar 

 in form, except that it is perhaps a little shorter and more 

 narrowed in front ; the medial excavation is broader than in 

 cornigerus and almost as m. jilicornis ; the anterior declivity is 

 sparsely punctured, much less so than in the one last named ; 

 the lateral elevations are longitudinal and laminiform, as in 

 that species, but the excavations at their base are smaller, 

 more deeply indented and subtriangular, and the crest of the 

 elevation, instead of being broadly rounded in the arc of a 

 circle, is very distinctly and nearly rectangularly angulated 

 and pei*pendicularly declivous in front. I may mention, in 

 order that the three species may be readily distinguished by 

 the notes here given, that this lateral elevation in O.fiUcoi-nis 

 is merely a subacute tubercle or cusj), and that the dorsal 

 groove is deeper, narrower, and more strongly punctured. 



The females of these species are scarcely to be distinguished, 

 except by minute differences in form and sculpture, which are 

 not very obvious without comparison.
