The life-history is thus described by Mr. Meyrick[9]: "The larva is wholly black, clothed with long black hairs, those covering segmental incisions brownish-ochreous. It feeds on _Senecio bellidioides_. The pupa is enclosed in a slight cocoon." {5}The perfect insect occurs in January, frequenting sunny, grassy slopes on the mountain-sides, at about 4,000 feet above the sea-level. It flies with great rapidity; hence it is generally very difficult to catch. METACRIAS HUTTONII, Butl. (_Phaos huttonii_, Butl., Cist. Ent. 487; _Metacrias huttonii_, Meyr., Proc. Linn. Soc. N. S. W., 1886, 750; Trans. N. Z. Inst. xxii. 216.) (Plate IV., fig. 6.) This interesting species was discovered at Lake Wakatipu, by Professor Hutton. The expansion of the wings of the male is 1-1/8 inches. The fore-wings are black; _there is an oblique crimson line near the base_, two broad longitudinal cream-coloured lines above and below the middle, and a double transverse series of oblong cream-coloured spots near the termen. The hind-wings are pale ochreous, with a black crescent-shaped spot near the middle, and a broad black band almost touching the termen except a little before the tornus. The female is apterous. Described and figured from a specimen in Mr. Fereday's collection. Family 2.--CARADRINIDÆ. The _Caradrinidæ_ are distinguished by the following characters:-- "Ocelli usually present. Tongue usually well developed. Labial palpi moderate, more or less ascending, second joint densely scaled, usually rough, terminal rather short, obtuse. Thorax usually densely hairy beneath. Posterior tibiæ with all spurs present. Fore-wings with veins 7 and 8 out of 9, 10 connected with 9. Hind-wings with veins 3 and 4 connate or short-stalked, 5 obsolete or imperfect, parallel to 4, 6 and 7 connate or short-stalked or seldom closely approximated only, 8 shortly anastomosing with cell near base, thence evenly diverging."
