with different kinds of leaves, for they feed on many shrubs and trees; but the commonest are clothed with bits of gum leaves attached only on the upper edge, and might be likened to a rag mat. When they infest pine trees in the garden, they are uniformly clothed with short lengths of pine needles and have a much neater appearance. The caterpillar is a stout black grub with the head and thorax dull white, mottled with brown. The male moth is a pretty little creature, with reddish brown antennae, the body thickly clothed with black down; the wings have very few scales, and are almost transparent, with a slight blotch in the centre of the hind pair. The Ribbed Case-moth, _Thyridopteryx herrichii_, differs from the others in constructing a smooth white silken bag, oval in form, angled on the sides, and with a slender tail at the base; and the long attenuated neck forms a regular stalk when attached to the twig; it measures about 2 inches, and is never covered with sticks or leaves. The caterpillar is blackish brown with the head and first thoracic segment lighter coloured. The moth is about 1 inch across the wings, thickly clothed with black hairs, and a reddish orange spot behind the thorax; the wings are semitransparent, with very few scales. Family 9. Cup or Slug Moths. LIMACODIDAE. [Illustration: =Fig. 115.=--_Doratifera vulnerans_ (Lewin). The “Cup or Slug Moth,” with larva and cup-shaped cocoon. (“Agricultural Gazette,” N.S.W.)] These are moderate sized moths with plump bodies thickly clothed with shaggy hairs, retracted heads, and toothed antennae. The caterpillars are curious short stout slug-like creatures feeding on the surface of the foliage; their feet are almost obsolete, while the under surface is quite flat, soft and fleshy; the whole body rests on the leaf when crawling along like that of a snail. The upper surface is saddle-shaped, with the two extremities raised and ornamented with fleshy spiny tubercles, with little bunches of sharp retractile spines like rosettes, which can be withdrawn into the tubercle or erected at will; the spines are sharp and appear to be hollow, and give a smart sting if they touch the body; in some of the American species, the stinging sensation is so severe as to cause serious swellings. When full grown they spin curious egg-shaped, brown, parchment-like cocoons attached at the base to the twig, with the apex rounded and forming a circular cap or lid, which, closely cemented on, is loosened and pushed off by the enclosed moth when she emerges. They do not pupate as soon as the cocoon is finished, but remain for a long time in a semi-caterpillar state before the chrysalis is formed. * * * * *
