_Bombyx trimacula_ measures 1¾ inches across the wings; it is a dark brown moth, mottled and marbled with white on the head, thorax, and tip of the abdomen, and forming a delicate wavy pattern across the fore wings interspersed with some blackish markings; it is found in Victoria. _Odonestis australasiae_ has been known under many different names: Lewin called it _Bombyx nasuta_, and his specific name was much more appropriate than the former, as it has the head produced into a regular point in front. The larger female measures about 2 inches across the wings, which are of a uniform dull reddish brown colour with faint markings on the fore wings; the hind ones are of a lighter tint. The short hairy caterpillars have a tuft of hairs standing out on either side of the head; in their natural state they feed upon the foliage of the black wattle, forming white silken cocoons, attached to the plant. It is sometimes called the “Long-nosed Wattle Moth,” and in Victoria is said to turn its attention to the apple-tree foliage. _Pinara despecta_ is a large, handsome, reddish fawn moth, with fore wings ornamented with several zig-zag bands across the centre. It is a thickset moth, often measuring over 3 inches across the wings. The larva feeds upon the foliage of the eucalyptus, and is a very slender caterpillar of a general greyish brown tint, with the sides of the body fringed with fine downy hairs, and when it is resting the fringes lie along the twig so closely that it is very hard to detect. It spins a large silken cocoon tinted with pink, attached to the leaves of the gum trees. _Cosmotriche exposita_ is a pretty little thickset moth of a uniform greyish brown tint, covered with fine soft downy hairs round the body and hind wings; the fore pair are thickly mottled with dark brown; the larger female measures about 1½ inches across the wings; the smaller male is a much darker brown insect with fine mottled fore wings. The caterpillar feeds upon the foliage of the “she-oak” (_Casuarina_), and is a slender greyish creature lightly clothed with grey hairs, marked with yellow and carmine on the sides of each segment, and black marks on the back. It forms an elongate oval cocoon attached to the twigs.
