 I, 1847, 85. 



Broadly oval or subrotnnd. Hrowii brou'/.ed, shiuini?. Thorax rather 

 coarsely punctured. Elytra more liiiciy puuctnrod, each puncture bearing 

 a very small, recumbent, scale-like hair. Hind tibire slightly curved. Length 

 4.5-5.5 mm. 



Knox County ; rai-e. July 8. A sini^ie specimen from border 

 of cypress swamp. Known from Illinois and westward. 



II. Chceridium Lep. 1825. (Or., ''a young pig.") 

 This genus contains two small, rounded species resembling 

 Hister in general appearance. They have the under side of thorax 

 transversely earinate and, as in the next three genera, the middle 

 and hind tibitc much expanded at apex. By this character they 

 may be readily separated from the small species of Cantiion. One 

 of the two has been taken in Indiana. 



*1728 (5441). Chceridium histeroides Web., Obs. Ent., 1801, 37. 



Rounded, convex. Bronzed above; dark chestnut 

 brown beneath, strongly shining. Clypens emarginate 

 or two-toothed. Thorax with a feeble median im- 

 pressed line on basal half and a small, deep rounded 

 impression ou each side; surface sparsely and shal- 

 lowly punctured. Elytra finely striate, the strioe in- 

 distinctly punctured. Male with spur of front tibijTe 

 dilated in the form of a small, circular sessile disk. 

 Length 6-7 mm. (Fig. 361.) 



Throughout the State ; common in the south- 

 ern, scarce in the northern counties. Occurs Figstji-. <^-

most abundantly in half-dried cow dung, and

III. CoPRis Geoff. 1762. (Gr., "dung.") 

 IMedium or large-sized species having the labial palpi broad, 

 compressed and S-jointed: the front coxae conical, large and prom- 

 inent ; all tarsal claws distinct luit without a bristle-tipped process 

 (onychium) between them. The males have the head or thorax or 

 both either tuberculate or horned. The species of Copris do not 

 transport excrement in balls any great distance, but bury it in bur- 

 rows on or near the spot.
