Those with only two teeth in tlie mandibles, and the labial palpi distinct, and which are destitute of wings, com- pose the sub-genera Myniups, Rhi/lirrhinKs (which have simple tarsi), and Lipanis (which has pulvillose tarsi). Those which have wings form the sub-genera Hi/pera and Hi/lobius. Those with three or four teeth in the mandi- bles, and the labial palpi nearly obsolete, form the subgenus Cleonus, including various other genera of Schonherr. The Longirosfres, or those with the antennas inserted at a distance from the insertion of the man- dibles, often near the middle of the rostrum, which is generally long, nearly correspond to the genera Lixus, Rhpichcenus, and Calandra, Fabr. In the first two the antennai are at least 10-jointed, but oftener ll-or 12-jointed ; the club being at least composed of the last three joints. Lixus, Fabr.— Nearly resembles Cleonus in the trophi, the long fusiform club of the antenna', the narrow elongated form of the body, and the armature of the feet. It is nearly linear in L. parapleclicus [a common British species], the,Iarva> of which live in the stems of Phellandrium, and produce in horses which may happen to eat them [with the plant], the disease called " parapl<''; Rhinocijllus, is composed of a species with the antennae scarcely elbowed, and which, from its supposed efficacy in the toothache, [has been specifically named R. anti-odontalgiciis]. RhknchjEnus, Fabr.— Has not such general characters. In some the sternum has not a cavity for the reception of the rostrum ; and of these some have the antennae ll-or 1
