(_Pasithea niphocrena_, Meyr., Trans. N. Z. Inst. xvi. 88. _Notoreas niphocrena_, ib. xviii. 184.) This species was discovered by Mr. Meyrick in the South Island, at Arthur's Pass, West Coast Road. "The expansion of the wings of the female is from 24 to 25 mm. (1 inch). Fore-wings moderate, termen rounded; rather dark fuscous, mixed and obscurely striated with orange; a curved white subdentate line before one-fourth, anteriorly blackish-margined; a similar white line beyond one-fourth, posteriorly blackish-margined; space between these sometimes suffused with orange; a slender irregularly dentate white fascia beyond middle, rather strongly angulated in middle, anteriorly blackish-margined, posteriorly closely followed by a dentate orange line; a dentate orange line near termen, dilated on costa. Hind-wings moderate, termen rounded; orange, lighter anteriorly; basal half dark fuscous mixed with orange, its outer edge irregularly curved; a dentate subterminal fascia and narrow terminal fascia dark fuscous, sometimes obscure. "Possibly when the male is known this may prove to be a _Dasyuris_. "I took two specimens on the mountain-side above Arthur's Pass at 4,500 feet, in January."--(Meyrick.) NOTOREAS SIMPLEX, n. sp. (Plate VIII., fig. 26.) A single specimen of this species was captured on Mount Arthur in the South Island. The expansion of the wings is about 1-1/8 inches. _The fore-wings are bright ochreous; there are four broad black transverse bands near the base, edged with white, and separated from one another by yellow spaces of almost equal width_; the outermost of these bands is situated a little more than half-way between the base and termen; the last two lines become obsolete before they reach the costa; there are no other markings, except a black shading on the termen near the tornus, which is traversed by an obscure jagged paler line; the cilia are white barred with black. The hind-wings are bright orange-yellow, without markings; the cilia are ochreous. The perfect insect appears in January. The type-specimen was taken on the mountain-side, at an elevation of about 4,000 feet. NOTOREAS FEROX, Butl. (_Fidonia ferox_, Butl., Proc. Zool. Soc. Lond. 1877, 392, pl. xlii. 8. _Pasithea ferox_, Meyr., Trans. N. Z. Inst. xvi. 88. _Notoreas ferox_, ib. xviii. 184.) (Plate VIII., fig. 17.) Two specimens of this species were captured by Mr. J. D. Enys, at Castle Hill in the South Island. The expansion of the wings is about 1 inch. The fore-wings are dull brown, with numerous fine, wavy, dusky lines and a faint dot above the middle. The hind-wings are orange-yellow, dotted with black near the base; _there is a rather broad_ STRAIGHT _transverse black band near the middle, followed by a much finer wavy line; there are three fine, wavy lines parallel with the termen, and the termen itself is finely bordered with black._
