quite touching hindmargin; above this are sometimes one or two very short blackish-fuscous lines on veins; generally a hindmarginal row of cloudy blackish dots: cilia ochreous-whitish, mixed with white, with two pale grey lines. Hindwings 1 ½, in male grey-whitish, with a grey lunule; in female whitish-grey, becoming darker grey posteriorly, with a darker lunule; cilia white, in female with a grey line. Conspicuously characterized by the sharply-defined interrupted blackish streak from base to apex. Christchurch and Lake Wakatipu, on dry grassy hill-slopes, in December, February and March; tolerably common. ∗ 3. Tetraprosopus, Butl Forehead vertical. Ocelli present. Tongue well-developed. Antennæ moderate, ⅔ of forewings, in male filiform, hardly perceptibly ciliated (⅙). Labial palpi rather long, straight, porrected, second joint beneath with dense projecting tuft, terminal joint moderately long, exposed. Maxillary palpi rather long, triangularly dilated. Posterior tibiæ with outer spurs half inner. Abdomen moderate. Forewings with vein 11 rather oblique. Hindwings almost twice as broad as forewings; 3 remote from 4, 4 and 5 stalked; lower median naked; discal area above it furnished with long hairs, continued almost to hindmargin; internal area loosely haired. Differs from Xeroscopa only by the approximate obsolescence of the antennal ciliations. But the extension of the discal hairs of the hindwings almost to the hindmargin is only found also in X. philonephes, of which the male is unknown, and it is possible that that species should be referred to this genus, in which case there would be an additional point of distinction. Butler's characters for this genus do not suffice to separate it from Scoparia. ∗ 60. Tetr. meyrickii, Butl (Tetraprosopus meyrickii, Butl., Ann. Mag. Nat. Hist., 1882, 97.) Male, female.—24–25 mm. Head and thorax greyish-fuscous, or reddish-ochreous-brown, often mixed with whitish, sometimes with a blackish-fuscous lateral stripe from eye to extremity of patagia. Palpi 2 ½, dark fuscous, mixed with white above, basal joint white. Antennæ dark fuscous. Abdomen light ochreous-grey. Legs whitish, anterior and middle pair suffused with dark fuscous. Forewings elongate-oblong, narrow, hardly dilated, narrow, costa almost straight, apex obtuse, hindmargin straight, rather oblique; greyish-fuscous or ochreous-fuscous, irrorated irregularly with whitish and darker fuscous; first line very obsoletely indicated, strongly angulated above middle; sometimes an irregular blackish streak from base along submedian fold to first line, often obsolete; a dark fuscous
