The members of the Genus _Haplonyx_ contain a number of curious, short, broadly rounded beetles generally found clinging to the twigs of eucalypts, but their larvae breed in the fleshy galls of the Brachyscelid coccids, where they destroy the gall makers and pupate in the cavity. _Haplonyx centralis_ is a typical dark brown species with a large white circle occupying the centre of the back. _Perissops ocellatus_, about ½ an inch in length, comes from the Tweed River N.S. Wales and Southern Queensland: it is of a general light brown tint; is oval and rounded in form, with the wing covers marked with buff, so that when viewed from behind it resembles a pair of eyes and nose on a man’s face.

(“Agricultural Gazette,” N.S.W.)] _Axionicus insignis_ is always found upon the trunk of the Kurrajong tree hidden in the crevices of the bark, where in spite of its size (¾ of an inch in length) it is very difficult to detect, owing to the exact blending of its white grey and brown markings with the tints of the bark. It lays its eggs in the injured bark; the larvae are typical obese legless white grubs; they feed between the bark and the wood often in such numbers as to kill large branches. They pupate in regular oval cocoons formed of gnawed wood and bark. _Tepperia sterculiae_ breeds in the seed pods of the Kurrajong, and is a smaller but somewhat similar tinted beetle clothed with brown and grey scales, the latter forming a well defined patch toward the apex of the wing covers. The two species of the Genus _Enteles_ are smaller, smooth, shining, black beetles, with the head and legs curving underneath the body; they are both found in the semi-tropical scrubs of the north. _Enteles vigorsi_ is marked with two white transverse lines crossing the elytra; while _E. ocellatus_ has more parallel lines crossing the transverse ones, making an eye-like pattern upon the back. The Grass-tree Weevil, _Trigonotarsus rugosus_, is 1½ inches in length; is of a uniform black colour; and of the typical Calandra or palm weevil shape, with a slender curved snout, and small head sunk into the thorax, with the dorsal surface of the thorax and elytra flattened. The obese white larva feeds in the roots of the grass-trees. Allied to this are the two tiny cosmopolitan grain weevils, _Calandra orizae_ and _C. granaria_, which are destructive pests to all kinds of grain and other food stuffs. Family 49. Longicorns.
