ceeding ones, and the four posterior tibie are slender or not thick, al- 
most cylindrical, slightly dilated at the extremity, and without deep 
lateral incisures or emarginations. 
The labrum is entirely concealed. The terminal lobe of the max- 
illee is simply pilose. ‘The antennz consist of ten joints; the suppu- 
tation of their number in the Encyc. Méthod., article Scarabées, 
which amounts to but nine, is erroneous. 
I-know two species, both from Brazil *. 
Sometimes the maxillee, usually corneous or scaly, are more or less 
dentated. In 
ScaraBaus proper.—Gerorrvures, Fab. 
The body is thick and convex, and the outer side of the mandibles 
sinuous or dentated. 
The equatorial countries of both hemispheres produce very 
remarkable species of this subgenus. 
S. Hercules, L.; Oliv., Col. I, 3, 1, xxiii, 1. Five inches 
long; black; elytra greenish-grey mottled with black; a re- 
curved and dentated horn on the head of the male, and a second 
one, long, projecting and pilose beneath, with a tooth on each 
side on the thorax. South America. Some travellers call it the 
Mouche cornue +. 
S. dichotomus, Oliv., Ib. XVII, 156. A fine maronne-brown ; 
a large bifurcated horn with cleft branches on the head; a se- 
cond one, smaller, curved and bifid at the end, on the thorax of 
the male. The East Indies. 
S. longimanus, L.; Oliv., Ib. TV, 27. Fulvous-brown ; head and 
thorax destitute of horns and tubercles; the two anterior legs 
more than half as long again as the body, and arcuated. The 
East Indies. 
S. punctatus, Oliv., Ib., VIII, 70. Black; punctured ; [no 
elevation in the shape of a horn in either sex; the epistoma 
truncated anteriorly, and the angles of the section slightly raised 
in the manner of teeth; two approximated tubercles on the 
middle of the head { (a). The only species in France. 
not differ from the preceding. The anterior margin of the labrum is salient or 
exposed. The maxille are terminated by a bundle of spinuliform cilia, acuated out- 
wards, with a crustaceous triangular lobe. The antennal club is nearly globular. 
His genus Dasygnathus, placed by him in his family of the Dynastides, is unknown 
to us, but we presume, from the description of its characters, that it approaches the 
preceding and following genus. 
* The AZgeon of Fabricius is perhaps congeneric. 
+ This species is the type of the genus Dynastcs, Kirby. The S. Actg@on forms an- 
other, that of Megasoma. See Lin. Trans., XIV. 
+ The Geotrupes of Fabricius, with the exception of the precited species, forming 
the genus Oryctes, and of the following one.

should be particularly noticed the large and splendid Sc. Tityus, the Anteus, &c.—
