COLEOPTERA. 5 
A third section, that of the XyLopurtr, will comprise the Geotrupes 
of Fabricius, and some of his Cetoniz. Here the scutellum is always 
distinct, and the elytra do not cover the posterior extremity of the abdo- 
men. The tarsial crotchets of several are unequal. The antennze always 
consist of ten joints, the three last forming a foliaceous club, of which 
the intermediate leaflet is never completely concealed or encased by 
the two others. The labrum is not salient, and its anterior extremity 
at most is exposed. ‘The mandibles are entirely corneous, and jut 
out beyond the sides of the head. The maxille are corneous or of a 
solid consistence, straight and commonly dentated. The ligula is 
covered by an ovoid or triangular mentum narrowed and truncated at 
its extremity, the angles of which are frequently dilated. All the 
legs are inserted at an equal distance from each other. 
A first division will comprise the Geotrupes of Fabricius. The 
males differ from the females in particular projections resembling 
horns or tubercles on the head or thorax, or on both, and sometimes 
also in the form of the latter. The epistoma is-small, triangular, and 
either pointed, or truncated and bidentated at the extremity. The la- 
brum is almost entirely concealed. Here, the maxille terminate in 
a simple, coriaceous, crustaceous lobe, more or less pilose and with- 
out teeth; there, they are entirely squamous, pointed, and present 
but a small number of teeth, accompanied with hairs. The mentum 
is ovoid or in the form of a truncated triangle. There is no projec- 
tion on the pectus. The tarsial crotchets are generally equal. The 
scutellum is small or moderate. Their colours verge on black or 
brown. 
Sometimes the maxille are terminated by a coriaceous or crustace- 
cus edentated lobe, simply pilose or furnished with spinuliform cilia.

Where the legs differ but little in length, and the four posterior 
tibie are thick, strongly incised or emarginated, with an extremely 
wide extremity, which, in several, is as if stellated. 
O. nasicornis ; S. nasicornis, L.; Ras., II, vi, vii. Fifteen 
lines in length; of a glossy maronne-brown; point of the epis- 
toma truncated ; a conical horn, more or less long, arcuated pos- 
teriorly on the head; front of the thorax cut obliquely, with 
three teeth or tubercles on the elevated portion posterior to the 
section ; elytra smooth. Found, together with its larva, in tan.

Smaller than the nasicornis; of a lighter but similar hue; a 
little recurved and pointed horn on the head of the male ; a deep 
excavation in the middle of the thorax; the last joint of the two 
anterior tarsi inflated, and with two very unequal hooks ; elytra 
finely and irregularly punctured *. In
