The Genus _Carpophilus_ contains 11 described species, most of which have a wide range over Australia; two are well known about Sydney from their habit of crawling into damaged fruit and feeding round the stone, causing it to decay very rapidly; they are also said to cluster round the fruit stalks, and by gnawing the base cause the fruit to drop. _Carpophilus pilipennis_ is a small reddish brown boat-shaped beetle, with the wing covers cut off at the hind margin, exposing the tip of the abdomen; it measures 1½ lines in length. _C. aterrimus_ is a somewhat larger flatter species of a uniform black colour, with the whole of the upper surface finely punctured; the legs and antennae are reddish brown. The abdomen is not so pointed as in the first species and much more of it is exposed on the dorsal surface. A curious little species, _Pocadius pilistriatus_, about ⅙ of an inch in length, is an elongate rounded brown beetle clothed with fine hairs. It feeds and breeds in the seed cases of the Kurrajong; the larvae are reddish brown grubs, elongate in form; they have three jointed antennae, and short black jaws, with well developed legs, and the tip of the abdomen bears two pairs of spines, the first pair erect, the second at the extremity but turning upwards. Family 15. TROGOSITIDAE. These are beetles of moderate size with five jointed tarsi, the first so small that unless closely examined it is not noticeable. They are found chiefly under dead bark or wood, but are carnivorous in their habits, and very dissimilar in form.

(“Agricultural Gazette,” N.S.W.)] The cosmopolitan “Cadelle,” _Trogosita mauritanica_, frequently found in bagged wheat, where the larvae gnaw out the embryo of the grain, is world wide in its range. It is a flattened, shining, black beetle; it was once placed among the _Heteromera_; and at first sight might be taken for a flattened carab. The Genus _Leperina_ contains a number of curious, elongate beetles flattened on the under surface; the dorsal surface is convex, and rounded at the extremities, with the integument covered with mottled grey, brown, and black tufts of scales imitating moss, and probably of a protective character, for they are generally found clinging to bark. _Leperina decorata_ was described by Erichson from Tasmania in 1842, but it has a wide range over the mainland. It measures from ¼ to ½ an inch in length; its ground colour is light chestnut brown mottled with black; the sides of the thorax deeply blotched with creamy white, and the back marked with indistinct patches of whitish scales.
