suffused with yellowish. Forewings oblong, hardly dilated, in male moderately broad, in female narrower, costa moderately arched, hindmargin not oblique, in male gently rounded, in female sinuate beneath apex; dull greyish-fuscous, irregularly suffused in male with golden-ochreous-yellow, in female with light yellowish-ochreous; in male extreme costal edge whitish except near base, in female costa narrowly white throughout: cilia in male ochreous-grey-whitish, basal half suffused with yellowish, in female white, base ochreous-tinged. Hindwings in male deep ferruginous-yellow mixed with dark grey, especially posteriorly, so as sometimes to form a broad dark hindmarginal band, and an obscure discal spot beyond middle, costa towards middle broadly paler, cilia whitish-yellow, at base and on anal angle ferruginous-yellow; in female dull white, becoming broadly pale yellow posteriorly, cilia white, at base pale yellow.

Conspicuous by its large size and distinctly coloured hindwings.

Common at Porter's Pass and Mount Hutt, in January, but probably confined to the mountain districts. I owe my specimens to the kindness of Mr. J. D. Enys, who also furnished Butler's original type.

Minor, alis ant. albidis, angulo revolucrum amplectente, fascia media obliqua, M. superius obsoleta, maculaque costæ triangulari saturate fuscis; post. albidis, apicem versus leviter ochreis.

Male, female.—15–17 mm. Head and thorax whitish; palpi elongate, externally mixed with dark fuscous. Forewings moderate, oblong, hardly dilated, costa in male slightly arched, bent before middle, in female strongly arched towards base, slightly sinuate beyond middle, hindmargin not oblique, rather strongly sinuate beneath apex; whitish, indistinctly strigulated with fuscous; basal patch represented in male by a sharply-marked blackish-fuscous narrow fascia proceeding from costa at ¼ obliquely inwards to disc, thence abruptly to base beneath costa, in female by a dark fuscous fascia from costa before ⅕, irregularly angulated below costa, bent inwards in disc as in male, but less defined; central fascia rather narrow, dark fuscous, from costa before middle to inner margin beyond middle, in male obsolete towards costa, in female distinct throughout, anterior edge dark-margined, posterior edge suffused; a rather ill-defined fuscous triangular patch extending on costa from middle to before apex, its lower extremity usually connected with central fascia and anal angle by two irregularly curved cloudy lines; a cloudy fuscous spot on middle of hindmargin, its anterior edge marked with from two to four blackish dots; hindmargin sometimes dotted with black: cilia grey-whitish, becoming dark fuscous
