reproduced a drawing of the moth and a monitor lizard’s head in the “Records of the Australian Museum,” to show this fancied resemblance, but if the correct colouration had been added the resemblance would have been very much less marked. The Genus _Pielus_ contains some large brownish moths with very hairy legs, two of which have been described from Australia: _Pielus hyalinatus_, slightly under 4 inches across the wings, is of a general chocolate brown tint with an irregular silvery white stripe and dark lines running through the centre of the fore wings; the hind pair are brown. The larvae feed in the roots of several species of wattles, and are frequently attacked by _Cordiceps_, the curious fungus that turns them into what are known as “vegetable caterpillars.” This species has a range from the southern parts of W. Australia through Victoria to North Queensland. Messrs. Olliff and Prince figured and described (Proc. Linn. Soc. N.S.W. 1887) a handsome variety of this moth under the name of _Pielus imperialis_. The marbled wood-moth, _Trictena labyrinthica_, is a large dark brown moth, measuring up to 6 inches across the wings, which are covered with a scroll-work pattern of lighter colour. The larvae of these also feed upon the roots of trees. In the COSSIDAE we have a typical goat-moth, _Culama caliginosa_, resembling the English species in form and habits. The larva is a short, dull, red, naked grub that feeds in the stem of the apple-gum, tunnelling round under the bark until nearly full grown, when it bores into the wood and pupates in a cocoon at the end. The moth is of a uniform delicate slate-grey, finely marbled with black lines all over the broad rounded wings, which are folded downward when at rest. The ZEUZERIDAE comprise some of our giant wood-boring moths; some are as large as small birds, with great rounded bodies, and grey wings thickly mottled with black, brown and fawn: _Zeuzera eucalypti_ has received an unfortunate specific name, for it feeds in the larval state in the stems and branches of several different species of wattles, and kills a great number of these trees by perforating them with great circular burrows; when ready to pupate, it forms a silken bag close to the outer skin of the bark, which has been gnawed away so that it can easily push its way out when ready to emerge. The moths have the usual brown tint mottled with irregular blotches of grey. The rust-coloured wood moth is a much larger species, and is commonly known under the name of _Z. liturata_, but is probably identical with _Z. cinerens_. It measures up to 4¼ inches across the wings, and is of a delicate mottled grey and brown tint, with the hind wings and central portion of the dorsal surface of the abdomen bright chocolate brown. The larvae of this and the following species live in the centre of the stems of large forest gums, and are said to take a number of years to come to maturity.
