The Genus _Leptops_ contains a large number of very characteristic beetles feeding upon the foliage of wattles and other scrub trees. They are usually grey, buff, or dark brown insects with thickened snouts and broad bodies. The Apple-root Borer, _Leptops hopei_, is sometimes a pest to the orchardist, damaging the roots of his apple trees; the beetle emerging from the soil crawls up the tree trunk, and laying her eggs upon the leaf, turns the edges over and gums them together with a sticky secretion; the young grubs hatch and crawl down to the roots. _L. tribulus_, often called by the Sydney boys the “Wattle Pig,” feeds upon the foliage of the black wattle; it is a much larger species, about 1 inch in length; dark brown to black in colour; the broad rounded body covered with short blunt spines, thickest towards the apex. The Grey-banded Leaf Weevil, _Ethemaia sellata_, described from S. Australia, has a wide range over the interior. The larvae are pale green legless creatures about ⅓ of an inch in length, lightly clothed with short hairs; they remain buried in the soil, coming out at night to feed upon plants, but if disturbed by a light they will drop to the ground and bury themselves very quickly. The beetle is ⅓ of an inch in length, dark brown, shaded with grey, which forms an irregular pattern on the thorax, legs, and elytra; rugose, deeply pitted; and the whole surface is clothed with white and brown scales. The AMYCTERINAE are a large group of weevils with such short thick snouts that they are quite unlike the typical forms generally found in open forest country among grass or hiding under logs or stones; they are wingless, the elytra soldered together forming a very thick solid integument. Macleay described a great number (Trans. Ent. Soc. N.S.W. 1865). _Psalidura elongata_, common in the interior, measures slightly over 1 inch in length; is of a uniform black colour with a reddish brown tint; the short head and flattened thorax are finely granulated, with the elytron closely ribbed and punctured. _Talaurinus tuberculatus_, about ⅔ of an inch in length, is black, very coarsely granulated on the thorax, with the whole of the flattened elytron thickly covered with blunt tubercules. Nearly 90 species or this genus have been described, chiefly by Macleay, ranging all over Australia. _Amycterus draco_ is one of the most remarkable armour plated species in the interior; it is black, with a small deeply ribbed head and angulated thorax; and the broad, somewhat elongated elytron is turned down at the extremity and covered with rows of raised bosses. _Acantholophus echinatus_, as the generic name implies, represents a group containing a number of species covered with spines that extend even over the upper surface of the head and thorax. The Genus _Cubicorrhynchus_ contains the smaller ground beetles, almost cylindrical, with short rounded head and thorax: they dwell under stones, and when exposed lie quite motionless as if dead, their dull
