THE SECOND FAMILY OF THE COLEOPTERA PENTAMERA,— Brachelvtra, Cuv. (Microptera, Grav.),— Have only one palpus to each maxilla, or four in all, [two maxillary; the outer lohe of the maxilla; not being palpiform, as in the foregoing tribes, and two labial] ; the antennse, either of equal thicknesj throughout, or a little tliickenefl at the tip, are generally composed of oval or lenticular joints; the elytra are very much shorter than the body, which is narrow and elongated, with the coxai of the fore* legs very large, and two vesicles near the anus, which the insect protrudes at will. These Coleoptera compose the genus Staphylin'us, Linn.,— Which have been regarded as forming the passage from the Beetles to the Earwigs, the first genus in the following order. In some respects, they approach the insects of the preceding family, and in many others, the Silphse, &c., belonging to the fourth family. They have in general the head large and flat, strong mandibles, antennae short, the thorax as broad as the abdomen, the elytra truncate at the tip but still covering the wings, which are of the ordinary size ; the dorsal semi-segments of the abdomen are as scaly as the ventral ones; from the anal vesicles a subtle vapour is discharged, which in some species smells very strongly of sulphuric ether. M. L. Dufour {Ann. Sci. Nat., vol. viii. p. 16.), has described the appai'atus by which it is secreted. ^ These Beetles [one of the largest of which is well known under the name of the Devil's Coach-horse], when touched turn up the end of the body, bending it in all directions; they also use it for the purpose of assisting in folding up their wings under the short elytra. The tarsi of the fore-feet are often broad and dilated, and the coxae of the four fore-legs are very broad. The major
