From eight to ten lines in length; violet black· elytra golden·green or brilliant cupreous, and finely st;iate/ each with three series of impressed and distant points. 1 Its larva inhabits the nest of the p1·ocessionary caterpillars on which it feeds, consuming several of them in the course ~fa clay; when filled to satiety, it loses all activity, and other larvre of the same species attack and devour it. It is black, and frequently found running about on the ground or trees, particu. larly the oak( 1 ). The third and last division of the Grandi pal pi presents an ensem· ble of characters which clearly disting'uishes it from the preceding ones. Most of the species that compose it are winged. The ante· riot· tarsi of the males are always dilated. The labrum is entire. The exterior pal pi are merely somewhat dilated or thicker at the extremity, with the last joint in the form of a reversed and elan· gated cone. The internal side of the mandibles presents no tooth worthy of notice; that in the middle of the emargination of the mentum is bific.l . . The middle of the superior margin of the ligula is elevated into a point. On the internal side of the antel'ior tibiz of several is a short emargination, or one of the two spurs is inserted higher than the other, so that in this respect these Carabici are ambiguous, and might be placed, as well as those of the ensuing sec· tion, directly after the Patellimani(2). They usually frequent wet places. Some of them, such as Omoplll'on, appear to connect this tribe with the following one ot· the Aquatic Carnivora. Some, in which the body is flattened, or convex and suborbicular, are provided with eyes of an ordinary size; their an tenure are linear and generally consist of elongated and almost cylindl'ical joints; the external sides of the maxillre are bearded, and the two internal spines of the two anterior tibire on a level at their origin; these tibire merely have a simple longitudinal canal. Sometimes the body is a flattened oblong oval, with a cordiform and truncated thorax posteriorly narrowed. The scutellum is dis· (1) Add C. inquisitor, Fab.; Panz. Faun. Insect. Germ.

Count Dejean is mistaken in supposing the calidum to be a common species-it is rare even in the south, where, I believe, it is only to be found. The Sayi is very common. .O.m. Ed.] (2) The Pogonophori are closely allied to the Loricerz. COLEOPTERA. 315 tinct. The three first joints of the anterior tarsi of the males are dilated. PoGONOPHORUS, Lat. Gyllen.-Leistus, Freel. Clairv.-Carabus, Fab. -Manticora, Panz. Remarkable for the elongation of the exterior palpi, those of the labium being longer than the head, for the mandibles, the external side of which fot•ms a salient and flattened angle, and for the projecting ligula terminated by three spines. The head is suddenly narrowed behind the eyes, and the joints of the antennre are long and slender. All the species known belong to Europe( 1 ). NEBRIA, Lat. ' The Nebrire only differ from the Pogonophori in negative characters, or in the much greater shortness of the palpi; in the want of dHatation in the external side of the mandibles, wh.ich merely forms a very small auricle, not extending beyond the base of the jaws; and in the' absence of the strangulation, or neck, in the head. The antenn:£ are also proportionably thicker, and composed of shorter joints(2). ALPJEus, Bon. Mere apterous N ebl'ire, somewhat more oblong, that . espe~iali y inhabit high mountains(3). Sometimes the body, arched or convex above, is nearly orbicular, the thorax very short, transversal, strongly emargiuate anteriorly, and wider and lobulate posteriorly. The scutellum is not apparent. The first joint alone of the two anterior tarsi of the males-and sometimes that of the intermediate ones as in the 0. melange-is sensibly dilated. 0MoPHRON, Lat.-Scolytus, Fab.
