The Painted Cup Moth, _Limacodes longerans_, is one of our commonest species. The female is about 1¾ inches across the wings; has a very large abdomen; is of a general dull brownish tint; the head and thorax are slightly coloured with red, and the under surface dark brown, the wings chocolate brown, with the outer margins light brown. The much smaller male has semitransparent wings, with the head and thorax marked with bright red. The larvae feed on eucalypts and are of a delicate green colour and of the typical form; about 1 inch in length; with four large tubercles at each end carrying a rosette of retractile red spines; the centre is marked with red and blue, and the outer margins are fringed with short tubercles. They form regular oval cocoons generally attached on their sides to the twig or bark. The Mottled Cup Moth, _Doratifera vulnerans_, is another common species, the larvae of which sometimes attack the foliage of apricot trees. It is a larger slug caterpillar than the last, with a patch of bright yellow in the middle of the back. The cocoons are pear-shaped with the apex somewhat contracted, showing the lid more distinctly. They sometimes swarm over the bush about Sydney N.S. Wales. The moths are of a general reddish brown tint with the fore wings marbled in the centre with a redder shade; the hind wings are lighter brown; they are somewhat smaller than the last species. * * * * * _Doratifera quadriguttata_ is of a dull reddish tint; the fore wings are crossed with a row of 3 darker raised spots, the hind wings being much lighter: the female measures about 1¼ inches, the male somewhat smaller. The larvae, when young, cluster together up to a dozen in number, and feed on the under-side of the leaf, but when full grown they scatter about, destroying much of the foliage of the gum trees. Numbers were collected near Gosford N.S.W. about the end of February. They are short and broad, black, with a pair of dull yellow fleshy horns in front, and 4 tubercles surmounted with bunches of yellow spines tipped with black at each extremity; the centre of the flattened back has rows of short yellow spines with a fringe of similar ones round the outer margins. When full grown they form the usual egg-shaped brown cocoon. * * * * * _D. acasta_ is a very similar moth, with a row of 6 or more similar spots crossing the fore wings. The larvae feed in the same manner, and are very plentiful toward the end of summer in the Bathurst district, N.S.W. Rainbow has figured the larvae of this species in the “Records of the Australian Museum” 1904.
