wholly obsolete and faintly outlined; two or three small blackish dots before middle of hindmargin; sometimes a faint greyish triangular costal patch before apex, containing two or three blackish costal dots: cilia whitish, base dotted with black, on upper half dark fuscous towards base. Hindwings white (in one female whitish-grey), spotted with grey; cilia white, base dotted with grey, round apex greyish.

Conspicuously distinct through the white ground-colour; in form of wing resembling a Cacoecia, but the male has not the slightest trace of a fold.

Originally described from one specimen taken near Auckland in January. I lately obtained five fine specimens near Christchurch in April, and have seen four others from the same place; the species is very distinct, and has no affinity with obliquana, Walk., as suggested.

Minor, alis ant. saturate griseo-fuscis, albido-irroratis; post. griseis.

Male.—17½ mm. Head, palpi, and thorax dark fuscous-grey, mixed with whitish-ochreous; palpi rather elongate, internally whitish-ochreous. Antennæ dark fuscous. Abdomen ochreous-grey, anal tuft pale greyish-ochreous. Legs ochreous-whitish, anterior and middle pair suffused with dark fuscous except at apex of joints. Forewings moderate, hardly dilated, costa moderately arched towards base, posteriorly nearly straight, hind-margin slightly sinuate, somewhat oblique; dark fuscous, densely mixed with whitish scales, and very obsoletely ochreous-tinged on small spots: cilia whitish mixed with dark fuscous. Hindwings fuscous-grey; cilia grey-whitish, with two very suffused fuscous-grey lines.

A very obscure-looking, yet very distinct species, in form approaching the preceding.

One fine specimen, kindly presented to me by Dr. W. H. Gaze, who took it near South Rakaia in March, amongst rough herbage.

Media, alis ant. ochreis, interdum fusco-suffusis, costa flava, triangulo ad basim magno saturate fusco vel etiam subviridi, fascia obliqua nigrescente, his sæpe obsoletis; post. albidis.

Male, female.—20–24 mm. Head, palpi, and thorax varying from pale ochreous to reddish-ochreous-brown; palpi moderate. Antennaæ whitish-grey. Abdomen whitish-ochreous or whitish. Legs whitish, anterior pair suffused with dark fuscous except at apex of joints, middle tibiæ more or less suffused with reddish-fuscous. Forewings moderate, posteriorly rather dilated, narrowed towards base, costa gently arched, somewhat sinuate in middle, hindmargin indented beneath apex, not oblique; varying from very
