The perfect insect appears in February, March and April, flying very actively in the hot afternoon sunshine. It is extremely abundant on the coast hills in the neighbourhood of Wellington. It also occurs commonly at Kekerangu, and is occasionally found on mountains as high as from 3,000 to 4,000 feet above the sea-level. I have observed that all the Wellington specimens have the transverse lines on the fore-wings narrow and mostly white; those from Mount Arthur broad and white, those from Kekerangu and Lake Wakatipu broad and orange-yellow. The last-named forms approximate most closely to some of the very yellow varieties of _Notoreas paradelpha_.[40] NOTOREAS STRATEGICA, Meyr. (_Pasithea strategica_, Meyr., Trans. N. Z. Inst. xvi. 87. _Notoreas strategica_, ib. xviii. 184.) (Plate VIII., fig. 15.) A single specimen of this conspicuous species was taken in the South Island at Lake Guyon, by Mr. W. T. L. Travers. The expansion of the wings is 1-3/8 inches. _The fore-wings are dull yellowish-brown, becoming blackish-brown near the base; there are two broad white transverse lines near the base, the outermost slightly curved, then a dull orange shading, followed by a very broad, outwardly bent, white transverse band, edged with black towards the base_; between this band and the termen there is a fine wavy white transverse line. _The hind-wings are dull yellowish-brown near the base, becoming blackish towards the termen; there is a small cream-coloured area near the base, then two rather broad, slightly irregular, cream-coloured bands, and a rather fine wavy white line near the termen._ The cilia of all the wings are white, barred with blackish-brown. The perfect insect appears in January. Described and figured from the type specimen in Mr. Fereday's collection. NOTOREAS CALLICRENA, Meyr. (_Pasithea callicrena_ Meyr., Trans. N. Z. Inst. xvi. 87. _Notoreas callicrena_, ib. xviii. 184.) (Plate VIII., fig. 16.) A single specimen of this very handsome species was captured by Mr. Fereday in the South Island, high on the mountains at the head of Lake Wakatipu. The expansion of the wings is 1-3/8 inches. _The fore-wings are deep orange-brown, shaded with black near the base and in the vicinity of the three cream-coloured transverse bands; the first of these bands is situated near the base, the second at about one-third, and the third, which is rather wavy, at about two-thirds_; there is a fine wavy white line close to the termen. _The hind-wings are dark grey, with two broad cream-coloured bands, the first near the base and the second near the middle_; there is a slender wavy line near the termen. The cilia of all the wings are cream-coloured, barred with brownish-black. The perfect insect appears in January, and evidently frequents high mountains. Described and figured from the type-specimen in Mr. Fereday's collection. {74}NOTOREAS NIPHOCRENA, Meyr.
