The species differs from the preceding in the following respects: The ground colour of the fore-wings is brighter, the markings are less oblique and much more jagged; the large white central band is often broken up into several distinct oval patches; the costal edge is very slightly shaded with {62}brown, _and the transverse lines do not disappear before reaching the costa_. The hind-wings are bright ochreous. _The cilia of all the wings are white, strongly barred with yellowish-brown_. There is slight variation in the details of the markings, but the species can always be immediately recognised. The perfect insect appears in December, January, and February. It frequents open grassy places at elevations ranging from 2,000 to 4,500 feet, and is often extremely abundant in these situations. XANTHORHOE COSMODORA, Meyr. (_Larentia cosmodora_, Meyr., Trans. N. Z. Inst. xx. 57.) This species was discovered by Mr. Meyrick in the South Island on Mount Arthur, at an elevation of 4,500 feet. _Female_.--27 mm. (slightly over 1 inch). Head, palpi, antennæ, thorax, abdomen, and legs whitish-ochreous, slightly brownish-tinged; abdomen with a double dorsal series of dark fuscous dots. Fore-wings with costa hardly perceptibly arched, termen slightly rounded, oblique; whitish-ochreous, slightly yellowish-tinged; a curved irregular black line rather near base, followed by a white line; median band rather darker, tinged with yellowish-fuscous towards edges, margined with dentate black lines and outside these with white, anterior from one-third of costa to two-fifths of dorsum, rather curved, posterior from two-thirds of costa to three-fourths of dorsum, somewhat prominent beneath costa, and with a more distinct double prominence in middle; two white dentate-edged spots within median band, first beneath costa, containing small black discal dot, second on dorsum; a waved white subterminal line; a fine dark fuscous terminal line interrupted into numerous dots; cilia whitish-ochreous, with dark fuscous bars hardly reaching base. Hind-wings whitish-ochreous, with faint darker greyish-tinged lines; a median band of four more distinct cloudy grey lines, first three straight, fourth well marked, rather dark fuscous, waved, somewhat prominent in middle, beneath confluent with third; a faint white subterminal line; cilia pale whitish-ochreous, with a faint greyish line tending to form spots. "Appears in January; one specimen. It is conceivable that this may be the other sex of the following species, but they are very dissimilar, and I do not at present think it probable."--(Meyrick.) XANTHORHOE BRYOPIS, Meyr. (_Larentia bryopis_, Meyr., Trans. N. Z. Inst. xx. 57.) Discovered by Mr. Meyrick in the South Island on Mount Arthur, 4,500 feet above the sea-level.
