Genus CXC. — Copris, Geqffroy. 



Antennas short, the basal joint considerably elongated, subclavate; the three 

 following short, equal in length, subhemispheric ; the two next very short, 

 transverse; the remainder forming an abrupt three-jointed club. Palpi, 

 maxillary elongate, four-jointed ; the terminal joint long, attenuated at each 

 end, acute; labial short, very hairy, triarticulate, the terminal joint slender, 

 truncate, minute: head triangular: clypeus emarginate in the centre, and 

 sinuated laterally ; armed in the middle with an acute or emarginate horn : 

 thorax transverse, considerably shorter than the elytra, retuse and tuber- 

 culated, or cornuted anteriorly: elytra entire: body convex: legs stout: 

 anterior tibia broad, rather curved, tridentate exteriorly: posterior biden- 

 tate, and bicalcarated at the apex : tarsi anterior, slender, and rather short ; 

 four posterior longer and dilated, especially the basal joint. 



Copris differs from Onthophagus, not only by its greater bulk, 

 but by having the body convex, the terminal joint of the maxil- 

 lary palpi acute, and of the labial ones minute and slender, the 

 clypeus emarginate anteriorly, the thorax distinctly shorter than 

 the elytra, &c. C. lunaris frequents sandy districts, where it 

 burrows obliquely to some depth, for the purpose of depositing its 

 eggs in safety. 



Sp. I. lunaris. Nigra nitida, thorace canaliculuto, medio retvso bifido, capitis 

 cornu erecto, in femina emarginato. (Long. corp. 8—10 lin.)

Shining black, with the outer margin of the clypeus, thorax, and base of the 

 elytra ciliated with castaneous hairs : clypeus semiorbiculate ; depressed, deeply 

 emarginate anteriorly, with an erect, elongate, subulate horn in the middle, 

 having its base bidentate within : thorax punctate, with a deep central 

 channel, anteriorly retuse, bilobed, with the sides prominent, acute, the 

 middle broad, truncate, bifid : elytra sulcate. 



Female with the horn on the head shorter, emarginate ; the thorax scarcely 

 luberculated.
