The expansion of the wings is about ¾ inch. The fore-wings are dark brownish-black, with five transverse white or orange-yellow lines, which vary considerably both in width and colour in different specimens; the two basal lines are almost straight, the rest are wavy, the last but one has, near the middle, a strong projection towards the termen. The hind-wings are bright orange, with three or four more or less broken black transverse lines. The termen is narrowly bordered with black; the cilia of all the wings are white, more or less distinctly barred with blackish-brown.

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 1⅜ 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.
