COLEOPTERA. 85 
being much longer than the following ones. They form the genus 
Curcutio of Linnzus. 
We will divide them into the Brevirostres and the Longirostres, 
according as the antenne are inserted near the extremity of the pro- 
boscis, and even with the origin of the mandibles, or further back, 
either near its middle or close to its base. 
The Brevirostres of this naturalist, according to the system of 
Fabricius, are divided into two genera. 
BRACHYCERUS., 
Where all the joints of the tarsi are entire and without brush or pel- 
let beneath. Their short and but slightly geniculate antenne present 
externally but nine joints, the last of which forms the club. ‘hey 
are destitute of wings, and their body is very scabrous or uneven. 
These Insects are peculiar to the south of Europe and to Africa, live 
on the ground and appear very early in the spring. The women of 
Ethiopia use one species as a sort of amulet; they pass a string 
through its body and hang it round their neck*.—* Voyage de M. 
Calliaud au fleuve Blanc.” 
CuRCULIO., 
Where almost the whole under part of the tarsi is furnished with 
short and stiff hairs, forming pellets, and their penultimate joint is 
deeply bilobate. Their antennze are composed of eleven joints, or 
even of twelve if we count the false one, which sometimes terminates 
them, the last of which form the club. 
As this genus, although much more restricted than in the Linnean 
system, still comprises numerous species discovered since the time 
of that naturalist, various savans, Germar and Scheenherr in parti- 
cular, have divided it into many others. It may be separated, from 
our own observations, into two principal divisions. 
1. Those in which the mentum, more or less widened superiorly, 
and more or less orbicular, occupies all the width of the buccal 
cavity, and entirely or very nearly conceals the maxille, and where 
the mandibles are not very sensibly dentated, or merely present a 
slight sinus under the joint. 
We may form a first subgenus, 
CycLomus. 
Of those Brevirostres in which, as in the preceding ones, the tarsi 
are destitute of a brush, and the penultimate joint is entire or 
slightly emarginated, and without very distinct lobes. To it should 
be referred the Cryptops, Deracanthus, Amycterus, and Cyclomus of 
Scheenherr J. 
* Oliv., Col., 82. M. Schcenherr forms the genus Episus with the species called 
the rostratus. The thorax is elongated and almost linear. 
+ These genera seem to connect themselves with the Myrniops and Rhytirhinus of 
this author, and in that case the Brachyceri should be placed further back, See 
our article Rhynchophores in the Dict. Class. d’ Hist. Nat.
