"The expansion of the wings of the male is from 24-25 mm. (about 1 inch). Fore-wings moderate, termen sinuate; dark fuscous, faintly striated, more or less sprinkled with whitish; a curved blackish line near base, posteriorly obscurely whitish-margined; a curved, obscure whitish fascia at one-third, blackish margined and bisected by a blackish line; a well-defined black discal dot; a white fascia, partially mixed with fuscous, beyond middle, anteriorly strongly blackish-margined, posteriorly more obscurely, and bisected by a blackish line, somewhat irregular, moderately angulated in middle; {68}an obscure dentate yellowish or whitish subterminal line; an interrupted black terminal line. Hind-wings moderate, termen rounded; dark fuscous; two nearly straight lines before middle, faintly darker; a faint paler or sometimes whitish sinuate fascia beyond middle, margined and bisected with darker. "Varies slightly in distinctness of pale markings. "Mount Hutt and Lake Wakatipu (5,400 feet), on the open mountain sides, in December and January; twelve specimens."--(Meyrick.) XANTHORHOE BULBULATA, Gn. (_Cidaria bulbulata_, Gn., E. M. M. v. 94. _Larentia bulbulata_, Meyr., Trans. N. Z. Inst. xvi. 84.) (Plate VIII., fig. 1.) This species has occurred in the South Island at Kekerangu, Christchurch, Castle Hill, and Dunedin. The expansion of the wings is barely 1 inch. _The fore-wings are very pale brownish-ochreous; there is a brown area near the base; a moderately broad brown central band with a distinct projection near the middle; the termen is broadly shaded with brown, with a wavy paler line in the middle of the shading_; there are often several oval paler marks in the middle of the central band, and pale brown spots and lines between the darker brown markings. _The hind-wings are bright orange, with the cilia pale brown._ The perfect insect appears from September till March, and frequents open, grassy places, from the sea-level to elevations of from 2,000 to 3,000 feet. Genus 12.--LYTHRIA, Hb. "Face rough-haired or loosely scaled, antennæ in male bi-pectinated, apex sometimes simple. Palpi with long rough hairs. Thorax roughly hairy beneath. Fore-wings with areole simple. Hind-wings with vein 8 anastomosing with cell to beyond middle."--(Meyrick.) (Plate II., figs. 39 and 40, neuration of _L. chrysopeda_.) We have two interesting little species in New Zealand. The genus also occurs in Europe, and probably elsewhere. LYTHRIA CHRYSOPEDA, Meyr. (_Arcteuthes chrysopeda_, Meyr., Trans. N. Z. Inst. xx. 48.) (Plate VIII., fig. 33 [M], 34 [F].) This bright-looking little species has been taken in the South Island at Mount Arthur.
