(Plate [IV]., fig. 4.)
This handsome species is at present only known by a single specimen, captured by Mr. W. W. Smith, near the summit of the Richardson Range, in South Canterbury, at an elevation of about 3,000 feet.
The expansion of the wings of the male is 1½ inches. The fore-wings are black, with two broad, dull yellow, longitudinal streaks; between the costa and the first streak is a very fine yellowish line, and between the two streaks there are three similar lines. The hind-wings are bright yellow, with a broad black band, parallel to the termen, interrupted just before the tornus; the vicinity of this black band is tinged with crimson. The body is black; the top of the head, collar, and sides of the thorax and abdomen are dull yellow. The female is probably apterous.
This species may be readily distinguished from the two following by the yellow collar, absence of any large spot in the centre of both fore-wings and hind-wings, and the red colouring of the termen of the hind-wings. The moth was taken in February, frequenting a species of Carmichælia. It may be looked for in the mountainous regions of South Canterbury, but at present nothing further is known of its habits.

This species was discovered by Mr. Meyrick on Mount Arthur in the Nelson District in 1886. Since that time I have taken eleven specimens in the same locality, and have seen several others, but as yet I have not heard of its occurrence elsewhere.
The expansion of the wings is 1½ inches. The fore-wings are black, with orange-yellow markings. These consist of a fine line near the costa, becoming very broad near the base, several elongate markings between the veins near the middle, a series of spots near the termen, and a broad streak parallel to the dorsum. The hind-wings are orange-yellow, with a curved black spot in the middle, and a broad black band on the termen, ending considerably before the tornus, and nearly broken a little before its termination. The female, according to Mr. Meyrick,[[8]] is "wholly whitish-ochreous; wings minute, aborted; legs short, stout, well developed."
