Notes on some Genera of COPEOPHAGOUS SCARAB.ffiID.5: of the United 



States. 



BY GEO. 11. HORN, M. D. 

 COPRIS, Geoff. 

 Our species are but few in number and seem hardly to call for a 

 separate essay, but as several of -them are closely allied and their de- 

 scriptions widely separated, the present paper may be of advantage to 

 many. 



Two sub-genera are indicated in our fauna. 



PINOTUS, Erichs,*(Archiv. 1847, I. p. 109).— Each elytron 7-striate ; hind tibife 

 dilated at apex, outer edge crenulate, never with an oblique ridge or tooth, 

 spur obtuse or emarginate at apex ; front iiarabolic, genae in front of eye 

 oblique, angle obtuse. 

 This subgenus is identical with Haldeman's Brachijcopris. 



COPRIS, Auct. — Each elytron 8-striate : hind tibiaj compressed, outer edge with 

 an oblique ridge or tooth near the middle, spur long acute; front semicircu- 

 lar, gense rectangularly produced, angle acute. 



C. (Pinotus) carolinus, Linn. {Scarabaeus) Syst. Nat. I. 2, p. 545; Drury, 

 Exot. Col. I, p. 77, pi. MS, fig. 2 ; Ilald. (Brachycopris) Proc. Acad. Ill, 125. 



Our largest species. This species may be further distinguished 

 from those of the next subgenus by the presence of a moderately deep 

 excavation on the underside of the prothorax within the anterior angle, 

 for the lodgment of the antennal club in repose; also, by the absence 

 of any elevated line proceeding from the coxa; outwards. Length .80 

 —1.10 inch; 20—28 mm. 



Abundant Southwardly and Westwardly of Pennsylvania. 



Our remaining species belong to the subgenus Copris. 

 Thorax opaque, densely, coarsely and evenly punctured anaglypticus, Say.
