The body is depressed, the .p,robos:Is slightly pomted before, and the tarsi are short. The palp1 at·e thtckcst at the extrl·mity. They form the subgenus RHINOSIMus, Lat. Oliv.-Curculio, Lin. De G.-.!J.r,thribus, Fab. Designated by Illiger under the denominat~on of Salpingus. Some entomologists have adopted both, but restnc.t th~ la~ter generally to species in which the clu~ of_ the antennre ~~ triat:tlculated, and applying the former, or Rhmostmus, to those m which the club is composed of four or five joints( 1 ). FAMILY IV. TRACHELIDES. In our second general division and fourth family of Hetero. merous Coleoptera, the head is triangular or cordiform, and borne on a sort of neck or pedicle, abruptly formed, beyond which being as wide at this point as the thorax, or wider, it canno; enter the cavity of the latter. The body is most com· monly soft the elytra are flexible, without strire, sometimes very short: and a little incli?~d in others. !he maxillre are never unguiculated. The JOints of the tarst are frequently entire and the hooks of the last bifid. Mo;t of the perfect Insects live on different plants, devour their leaves or suck the nectar of their flowers. Many, when seized, cur~e their head and fold up their feet as if they were dead; the others are very active. . We will divide this family into six tribes, formmg as many genera. . In the first, or that of the LAGRIARIJE, the body IS el~n· gated and narrower before; the thorax either almost cyhn· drical or square, or ovoid and tru!lcated; the antennre, m· ser ted (1) See Lat., Gener.

The species indigenous to France are found in woods, on various plants; their body is soft, their elytra are flexible, and like the Meloes, the Cantharides, when taken, counterfeit death. This tribe is formed of the genus LAGRIA, Fab.-Chrysomela, Lin.-Cantharis, Geoff. Those species, in which the antennre gradually enlarge, and are either wholly or partly almost granose, with the last joint ovoid or oval; in which the head projects but little before, and is prolonged and insensibly rounded behind; and where the thorax is almost cylindrical or square, compose our genus LAGRIA properly so called( I). That, which I have named STATYRA, consists of species, similar at a first glance to the Agt·re, of the family of the carnivorous Pentamerous Coleoptera. Here the antennre are filiform and composed of almost cylindrical joints, the last of which is very long and tapers to a point. The head projects anterior] y, and is strongly and abruptly narrowed behind the eyes. The thorax is longitudinal, oval and truncated at both ends. The sutural extremity of the elytra terminates in a tooth or spine(2). We refet·, with some hesitation, to the same tribe our genus 1-iEMIPEPLus- Fam. Nat. du Regne Anim., p. 398-where the antennre are filiform, almost granose, short and geuiculate, with the second and third joints shorter than the following ones; where the body is linear and depressed; the head cordiform, somewhat wider posteriorly than the thorax; the eyes are entire and oval; the thorax forms a long square, slightly narrowed posteriorly; the elytra are trun- (1) See Fabricius, Olivier, Latreille and Schrenherr.
