margin above middle: cilia grey or greyish-ochreous, with a darker line. Hindwings light grey, sometimes partially ochreous-tinged, spotted and often suffused with darker grey; cilia whitish-grey, with a darker basal line.

Rather variable in colour and considerably in intensity of marking; but easily separated from all the other species of the genus by its dull grey hue.

Occurs rather commonly at Christchurch, Dunedin and Blenheim, in December, January and March, seeming attached to Leptospermum. Butler's cuneigera is founded on a light-coloured specimen with strongly-marked costal blotch, received from Blenheim; I have seen two similar specimens from the same locality, but can find no reliable point of distinction and have no doubt of their identity.

Minor, alis ant. rufis, griseo-mixtis, macula magna posteriori albida ochreo-mixta; post. saturate griseis.

Female.—14 mm. Head, palpi and thorax reddish-ochreous-brown, mixed with whitish-grey; palpi moderate, grey-whitish internally and beneath. Antennæ grey, annulated with black. Abdomen dark grey. Legs grey, anterior and middle tibiæ and all tarsi suffused with dark fuscous, except at apex of joints. Forewings rather narrow, oblong, costa gently arched, apex nearly rectangular, hindmargin sinuate, not oblique; reddish-ochreous-brown, thickly mixed with dark fuscous-grey; a tolerably well-defined large whitish blotch on hindmargin, almost reaching costa and anal angle, extending in disc to ⅔ from base, containing two small pale ochreous spots mixed with grey scales, one on its upper and the other on its lower margin, almost uniting in middle, so as to bisect the blotch: cilia reddish-ochreous-brown mixed with grey. Hindwings dark grey, apex blackish-grey; cilia whitish-grey, with a dark grey basal line.

Very distinct by its deep colouring and the posterior whitish blotch.

One fine specimen taken at light at Christchurch in March. The male being unknown, the generic location is not absolutely assured, but I have little doubt the species is correctly placed.

Major, alis ant. fuscis, M. flavo, F. ochreo-suffusis, costa F. alba; post. M. saturate flavis, posterius nigro-mixtis, F. albis, posterius dilute flavis.

Male, 27 mm.; female, 30 mm.—Head, palpi and thorax in male brownish-ochreous mixed with fuscous, in female ochreous-whitish suffused with pale ochreous; palpi rather long. Antennæ in male fuscous, in female whitish-ochreous. Abdomen in male yellowish-ochreous mixed with fuscous, in female ochreous-whitish. Legs ochreous-whitish, anterior and middle pair more or less suffused with fuscous-grey, posterior tibiæ in male
