tenuated antennae, as long or nearly as long as the thorax, wliilst 

 here they are thick and much shorter. The abdomen also is ventri- 

 cose. To Omias * and Thylacites \ we imite several of the genera of 

 Schoenherr. We may retain that of Hyphantus, closely related to 

 Othiorhynchus J, 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 antennee 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 antennae, 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, Schoenherr, to which may be 

 united his Rhytirrhinus. 



In others, also apterous, the imder part of the tarsi, as in most of 

 the Rhyncliophora, 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., — Phylonomus, Coniatus, Schcenh., where the tibiae 

 have no hook at their extremity, or but a very small one ||, and that 

 of Hylobius, 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. 

 tamarisci, Fab., which for beauty of colours rivals the most splendid 

 exotics. It is 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 antennre 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 Cleonus ff.
