A very distinct variety frequently occurs in which the entire ground colour is _orange-yellow_. This variety can be artificially produced by exposing a typical specimen to the fumes of bruised laurel leaves. Intermediate forms may also be found, but are much scarcer than either the typical form or the variety.
The larva (according to Mr. Purdie[26]) is about ½ inch long; colour brownish, surface very rugged; body tapering somewhat towards the head. Two pairs of small dorsal tubercles about the middle, the posterior pair being larger; oblique lateral dark markings faintly seen on dark ground colour; below lighter. Food-plants: _Aristotelia_, _Leptospermum ericoides_, _Rubus_ (?), and _Muhlenbeckia_ (?). Found in December and January.
The perfect insect appears from September till May, and is often very common. It rests on tree-trunks with outspread wings, in which position it so closely resembles a patch of moss that it is extremely difficult to detect, even when specially searched for.
This species was discovered by Mr. Philpott at West Plains, near Invercargill.
The expansion of the wings is 7/8 inch. The fore-wings are rather dull green; there is a reddish-brown patch near the base, followed by two, slightly oblique, reddish bands; the central band is very broad, green, traversed by numerous fine wavy lines; there is a broad reddish band on the termen. The hind-wings are slaty-grey, tinged with pink towards the termen and dorsum. The cilia of all the wings are pink barred with black.
Two other specimens kindly given to me by Mr. Philpott have the bands on the fore-wings more or less brown in place of red, but are otherwise identical.
This insect is evidently very closely allied to _C. bilineolata_, but its larger size, longer wings, and barred cilia will, I think, distinguish it from that species.

This beautiful insect was discovered on the Mount Arthur Tableland in January, 1896, at an elevation of about 4,000 feet.
The expansion of the wings is 1-1/8 inches. _All the wings are very pale greenish-grey._ The male has three distinct dark brownish bands near the base, an irregular broad suffused band near the middle, becoming obsolete before it reaches the dorsum, a dark patch at the apex, another patch on the termen below the apex and another near the tornus. The hind-wings are traversed by numerous, very fine, wavy blackish lines, becoming darker towards the dorsum. In the female there are three wavy reddish-brown bands on the costa of the fore-wings, becoming obsolete towards the dorsum, then a wavy yellowish line, followed by two rust-red patches. The hind-wings resemble those of the male. Both sexes have the veins dotted with black, and the cilia of all the wings are grey barred with black.
