. Australian insects. Insects. â I'JS COLEOPTERA. with the head, thorax, and legs mottled with dull blue, and the whole of the elongated wing covers dull blue except a dorsal stripe of the prevailing yellow which widens out towards the apex. Family 45. Woodborers. SCOLYTIDAE, This is a group the members of which are allied to the Weevils, but differ in having a short broad snout with clubbed antennae, and the tibiae toothed on the outer edge. Only a few species have been described from this country, but several of them are well-known pests, and like the smaller species of the Auger Beetles are usually attracted to dying trees. In the Genus Hylesinus we have one, H. porcatus, which attacks the terminal buds of both the wild and culti- vated figs. It is a short thickset black beetle, about 2 lines in length, with the head turned down to the fore-legs, and Fig. 80-âHylenhnis j'lci (Lea). -branch Beetle, better known under the name of H. porcaUis (Chap.)- ("Agricultural Gazette," ) the clubbed antennae 5 jointed; the head and thorax are rugose, and the 'wdng covers finely striated; the whole insect is lightly clothed with fine hairs. The Ambrosia Beetle, Xyleborns solidus, is a common beetle in the bush, and has lately turned its attention to fruit trees; boring into the branch and then gnawing a chamber right round under the bark, she dejiosits her eggs at the end of the burrow, at the same time killing the branch and causing it to snap off. This beetle is about y^ of an inch in length, of a uniform black colour, with the legs and antennae reddish brown. It is stout and cylindrical in form; the head is turned down in.
