About eight lines in len h· black; glossy; head WI'd er t h an t h e thorax; great pat·t of gthl ' abdomen and elytra cinereous grey, dotted and spotted wit~ black. In earth, dung, &c. S. murinus, Fab.; Panz., ib., LXVI, 16. From four to six lines long; head, thorax and elytra deep bronze, glossy, with dusky spots; scutel yellowish, marked with two atrous spots· abdomen black; greater part of the antennce reddish. Found with the preceding. S. erythropterus, L.; Panz., XXVIII, 4-. From six to ten lines in length; black; elytra, base of the antennce and legs fu[. vous(l). The others, which are linear, with a head and thorax elongated in the form of a long square, have their antennce approximated at base, and strongly geniculate and gl'anose; their anterior tarsi are usually not at all or but very slightly dilated. The anterior tibia! are spin· ous, with a stout spine at the extremity. The labrum is small. They form the genus Xantlwlinus of some entomologists(2). PINOPHILus, Grav. Palpi filiform; but the antennre inserted before the eyes, outsideof the labrum, and near the exterior base of the mandibles(3). LATHROBIUM, Grav.-Prederus, Fab. Palpi suddenly terminated by a pointed and frequently indistinct joint, much smaller than the penultimate; those of the maxillz much longer than the labials; the antennce inserted as in Pinophilus; anterior tarsi strongly dilated in both sexes; length of the last joint of the four posterior tarsi almost equal to that of the four preceding ones taken together( 4 ). (1) See the Monograph of this family-Coleoptera Microptera-by Graven· horst; Panz., Index, Entom., pars 1, p. 208, et seq.; Lat. ib., I, 285. Refer to this genus the following species of Olivier: aureus, reneus, hmmon·hoidalia, ocuJa. tus, erythrocephalus, similis, cyaneus, pubescens, cupreus, stercorarius, brunnipa, pilosus, politus, ammnus, besides those above described.

In some of them, P JEDERus, Lat.-the penultimate joint of the tarsi is bifid( I). P. riparius; Staphylinus riparius, Panz., Faun. Insect. Germ., IX, 2. About three lines in length; very narrow and elongated; fulvous; head, pectus, superior extremity of the abdomen and knees, black; elytra blue. Very common in wet sand, under stones, among the roots of trees, &c. In the others, STILIOI, Lat.-all the joints of the tarsi are entire(2). Ev.JESTHETus, Grav. The antennre also inserted before the eyes, but hardly longer than the head, and almost entirely moniliform; the body but slightly elongated, and the head as wide as the thorax(3). The L. ekmgatum (S. elongatus, L.) is figured by Panz, lb. IX, 12;-StaphylintH lintari8? Oliv., Col. III, 2, iv, 38. See also Gyllenh., Insect. Suec. I, pars I, p. 363, et seq., and the Catalogue of Count Dejean, p. 24. . (1) M. Lefevre has brought an Insect from Sicily allied to Pa:derus, but ev•· dently forming a new genus. The fourth and last joint of the maxillary palpi is here very distinct, and gives them a clavate termination. The last joi.nt of the antenna: is ovoido-conical and larger than the penultimate. The head 1s connected with the thorax by an elongated pedicle, on a level with the former at its origin. The thorax is narrow and elongated. The two anterior tarsi are greatly dilated; the first joint of the others is very long, and their penultimate appeared to me emarginated or bifid. 1 will distinguish the genus by the name of PRocxaaus, and this species shall be dedicated to the zealous naturalist who discovered it.
