"_Male, female_.--The expansion of the wings is 32-34 mm. (about 1¼ inches). Fore-wings moderate, in female narrower and more elongate, termen rounded; pale whitish-grey, slightly ochreous-tinged; an indistinct suffusion of dark fuscous scales before middle; a small dark fuscous discal dot; a rather irregular cloudy dark fuscous line beyond middle, sinuate beneath costa, shortly angulated in middle; a very faint stria beyond this; a terminal band composed of two rows of cloudy partially confluent dark fuscous spots, separating on costa; cilia pale whitish-grey. Hind-wings moderate, in female narrower, termen rounded; ground colour as in fore-wings, with a few grey scales posteriorly. "A remarkable-looking species. "I took two fine specimens above Arthur's Pass (4,600 feet), in January."--(Meyrick). I am unacquainted with this species. It is evidently very conspicuous and distinct. XANTHORHOE CATAPHRACTA, Meyr. (_Larentia cataphracta_, Meyr., Trans. N. Z. Inst. xvi. 79.) (Plate VII., fig. 33 [M], 34 [F].) This large and conspicuous species has occurred in the South Island at Mount Arthur, Arthur's Pass, Lake Guyon, and Lake Wakatipu. The expansion of the wings of the male is 1-5/8 inches, of the female 1½ inches. _The fore-wings are dull yellowish-brown, with numerous slightly waved oblique black and white transverse bands; one very broad white band is situated near the middle, and another at about three-fourths; there is a broad longitudinal reddish-brown line on the costal edge, in which the transverse lines almost disappear_; there is also a pale, somewhat triangular, area at the apex. The hind-wings are very pale greyish-ochreous. The cilia of all the wings are very pale ochreous. The female is duller and paler than the male. The perfect insect appears from December till March, and frequents grassy slopes on the mountain sides, at elevations of from 3,000 to 4,000 feet. I observed this insect in great abundance on the Humboldt Range at the head of Lake Wakatipu, but have not found it at any of the other Alpine localities I have visited, so I imagine that it is a rather local species. XANTHORHOE CLARATA, Walk. (_Larentia clarata_, Walk. 1197; Butl., Cat. pl. iii. 14. _Cideria pyramaria_, Gn., E. M. M. v. 93. _Larentia clarata_, Meyr., Trans. N. Z. Inst. xvi. 79.) (Plate VII., fig. 31 [M], 32 [F].) This conspicuous species has occurred in the South Island at Lake Rotoiti, Mount Arthur, Castle Hill, Mount Hutt, Dunedin, and Lake Wakatipu. The expansion of the wings of the male is 1½ inches, of the female 1-3/8 inches.
