tenuated antennz, as long or nearly as long as the thorax, whilst 
here they are thick and much shorter. The abdomen also is ventri- 
cose. To Omias * and Thylacites + we unite several of the genera of 
Scheenherr. We may retain that of Hypuanrus, closely related to 
Othiorhynchus +, but distinguished from it by the thorax, which, 
compared to the abdomen, is very large and almost globular. 
Our second general division of the genus Curculio of Fabricius 
differs from the first in the narrowing of the mentum, which, not oc- 
cupying the whole width of the buccal cavity, leaves the jaws ex- 
posed on each side, and in the mandibles that are evidently dentated. 
The club of the antenne is frequently formed by the five or six last 
joints. 
Some have scarcely more than two teeth in the mandibles. Their 
labial palpi are distinct. The club of the antennze, which is tolerably 
abrupt, only commences at the eighth or ninth joint, and is not elon- 
gated and fusiform. 
The body, although frequently oblong, is not of the same figure. 
Some are apterous, and their tarsi are destitute of pellets. Their 
penultimate joint is slightly bilobate. 
Such is the subgenus Myniops, Scheenherr, to which may be 
united his Rhytirrhinus. 
In others, also apterous, the under part of the tarsi, as in most of 
the Rhynchophora, is furnished with pellets, and the penultimate 
joint is strongly bilobate. They form the subgenus Liparus, which 
will also comprise various other genera of the same author §. 
Those which are winged may form two other subgenera, viz, Hy- 
PERA, Germ.,— Phytonomus, Coniatus, Schoenh., where the tibize 
have no hook at their extremity, or but a very small one ||, and that 
of Hyxorrus, where there is a very strong one at their inner extre- 
mity **. 
Among the species of the first, one is found on the 'Tamarisk,—C. 
tamarisct, Fab., which for beauty of colours rivals the most splendid 
exotics. Itis the type of Schcenherr’s genus Coniatus. 
The others, whose mandibles have three or four teeth, present a 
mentum abruptly narrowed near its superior extremity, truncated, 
and with scarcely perceptible palpi. Their antenne terminate almost 
gradually in an elongated fusiform club. The body has frequently a 
similar figure. Olivier confounded them with the Lixi, from which 
in fact they differ but little. 
They will compose the subgenus CiEonus ++}.
