The perfect insect appears in December and January, and frequents wooded valleys on the lower slopes of the mountains, at elevations of from 2,000 to 3,000 feet. XANTHORHOE CAMELIAS, Meyr. (_Larentia camelias_, Meyr., Trans. N. Z. Inst. xx. 58.) This species was discovered by Mr. Meyrick in the North Island at Whangarei. "The expansion of the wings of the male is 23 mm. (rather less than 1 inch). Head, antennæ, and thorax whitish-ochreous, greyish-tinged, with a few dark fuscous scales. Palpi fuscous. Abdomen whitish-ochreous, with a double dorsal series of dark fuscous dots. Legs whitish-ochreous, irrorated with purple-reddish and dark fuscous. Fore-wings with costa rather sinuate in middle, on anterior half gently, on posterior half very strongly arched, termen moderately sinuate below apex, bowed in middle; light greyish-ochreous, with numerous cloudy, waved, brown-grey transverse lines, somewhat bent near costa; a black discal dot; margin of basal patch and anterior edge of median band indicated by series of very minute white dots, preceded and followed by black points; posterior edge of median band marked by a darker line, followed by a fine white line reduced on lower half to a series of points, subterminal line represented by four cloudy blackish dots on upper half and another above tornus; cilia greyish-ochreous (imperfect). Hind-wings fuscous-whitish; a median band of four cloudy greyish lines, bent near costa; a cloudy grey spot above tornus; cilia fuscous-whitish (imperfect.) "Appears in December. Immediately recognisable by the peculiar form of forewings."--(Meyrick.) {66}XANTHORHOE FALCATA, Butl. (_Larentia falcata_, Butl., Trans. N. Z. Inst. xx. 58.) A single specimen of this species is in the British Museum collection of New Zealand Lepidoptera. Of this specimen Mr. Meyrick remarks as follows:-- "This appears to be a good species allied to _X. camelias_, but with the costa of fore-wings less arched posteriorly, and posterior edge of median band practically straight, not bent near costa; also much darker in general colouring. I have not yet seen any specimen except the original type." XANTHORHOE OBARATA, Feld. (_Cidaria obarata_, Feld. cxxxii. 33. _Larentia obarata_, Meyr., Trans. N. Z. Inst. xvi. 82.) (Plate VII., fig. 45.) This little species has occurred at Wellington in the North Island, and at Christchurch and Mount Hutt in the South Island.
