COLEOPTERA, ¥ | 
lum. The body is also an oblong oval, and plane above; the sides 
of the thorax are obliquely and abruptly truncated. The interme- 
diate coxe are directed longitudinally with the body, and parallel to 
its sides. 
In all the following Coprophagi, the four posterior tibie are al- 
ways dilated at their extremity, and almost in the form of an elon- 
gated triangle; the intermediaries, as in the last, terminate in two 
stout spurs or spines; but the head or thorax, or both in the males, 
presents horns or projections which distinguish them from the fe- 
males. In several, the three last joints of the antenne are semi- 
cupular and concentrically piled or fitted into each other. They 
compose the genera Onitis and Copris of Fabricius. 
Two subgenera with a foliaceous antennal club present a charac- 
ter which, in this section, is exclusivly peculiar to them: the third 
joint of the labial palpi is but slightly or not at all distinct, and the 
second is larger than the first. 
OniTicELLus, Zieg. Dej. 
The body is oblong and depressed; the thorax large, nearly oval, 
and almost as long as it is wide, and always smooth. The scutellum 
is distinct. Simple and elevated lines or tubercles on the head distin- 
guish the males from the females *. 
OntHopHacus, Lat.—Corris, Fab. 
No scutellum. Their body is short, thorax thick, broader than 
long, either almost semi-orbicular or nearly orbicular, but strongly 
emarginated or truncated before. The head, and frequently the tho- 
rax, of the male is furnished with horns. 
O. taurus; S.taurus, L.; Oliv. Col. I, 3, viii, 63. Small; 
black ; two semicircular horns on the head of the male; two 
transverse and elevated lines on that of the female. In cow- 
dung. 
O. nuchicornis; S.nuchicornis, L.; Panz., Faun. Insect.Germ. 
I.and XLIX, 8. Small; black; elytra grey with little black spots; 
a compressed laminiform projection terminating in an almost 
straight point on the hind part of the head of the male; two ele- 
vated and transverse lines on that of the female; a tubercle on 
the anterior of the thorax. With the preceding. 
Africa and India produce several other species, some of 
which are very brilliant, but they are all small +. 
Two subgenera presenting a scutellum, or sutural hiatus indi- 
cating its place, and which the anterior legs are frequently destitute 
of tarsi, and frequently also longer, more slender and arcuated in the 
males, are distinguished from all other Coprophagi by the form of 
their antennal club; its first joint, or the seventh of the whole num-
