with small spines, and the last joint of their tarsi is as long as all the 
preceding ones taken together, or longer. The first joint of the 
labial palpi is dilated internally, and almost triangular. There isa 
fossula on each side of the thorax* . 
Other Coprophagi, very analogous to the preceding ones, and also 
placed by Fabricius among the Ateuchi, are distinguished from them 
by the intermediate tibiz, the extremity of which, as well as that of 
the two last, frequently dilated or clavate, presents two spines or 
spurs. The epistoma, in several, exhibits but four or two teeth. The 
first joint of the labial palpi is always larger than the second, and 
dilated externally. The third and last joint is distinct. First comes 
Sisypuus, Lat, 
The Sisyphi differ from the other Coprophagi in their antenne, 
which consist of but eight joints, and in their abdomen, which is tri- 
angular. The four last legs are long and narrow, their thighs cla- 
vate. The body is short and thick; no scutellum f. 
Cirrcexuium, Lat. 
The body hemispherical and convex; the abdomen almost semi- 
circular, and the lateral edges of the thorax straight or not dilated, 
or but slightly, in the middle. No scutellum, Five or six denta- 
tions in the epistoma {. 
Coproszius, Lat, 
No scutellum; the body ovoid, not arched, or but slightly so: mid- 
dle of the lateral margins of the thorax dilated into an obtuse or 
rounded angle, abdomen nearly square; epistoma bidentate. These 
Insects are more particularly proper to the western centinent §. 
Those species, in which the four posterior tibiee are proportionally 
shorter, dilated, or remarkably widened at the extremity, and the 
first joints of the tarsi are broader, form the genus Cheridium of 
MM. Lepeletier and Serville—Encyc. Méthod.;—we will also unite 
to the Coprobii the Hyboma of the same authors. 
Another subgenus allied to the preceding, the species of which are 
also proper to America, that which they call Afschrotes, but which 
had been previously published by Dalman—Ephem. Entom., 1824— 
under another name, that of
