to anal angle; a white dot in disc at ⅓, a second hardly beyond middle, and a third somewhat larger on fold between these; a row of whitish-ochreous dots along hindmargin and apical fourth of costa: cilia dark fuscous. Hindwings dark fuscous; cilia fuscous, with a darker basal line. The conspicuous white discal dots afford an easy point of recognition. Dunedin, in January; one specimen received from Mr. A. Purdie. 11. Thamnosara, n. g. Head with appressed scales, sidetufts moderate, loosely spreading. Antennæ in male moderate, biserrate, moderately and evenly ciliated (1), basal joint rather long, without pecten. Palpi moderate, second joint not exceeding base of antennæ, densely scaled, beneath with long projecting hairscales, forming a large square tuft, terminal joint slightly shorter than second, slender, curved. Thorax smooth. Forewings moderate, apex rounded, hindmargin oblique. Hindwings as broad as forewings, elongate-ovate, hindmargin rounded, cilia ⅗. Abdomen moderate. Posterior tibiæ shortly rough-haired above. Forewings with vein 7 to costa, 2 from rather before angle of cell. Hindwings normal. Allied to Gymnobathra, of which it is probably a development; differs from all New Zealand genera except Aochleta in the tuft of the second joint of palpi; but in Aochleta the tuft is much less developed. Vein 2 of the forewings is widely remote from the angle of the cell; and veins 3 and 4 of the hindwings are stalked. Only one species is known, peculiar to New Zealand. 25. Thamn. chirista, n. sp. Minor, alis ant. albido-fuscis, saturate fusco creberrime irroratis; post. griseis. Male, female.—13–14 mm. Head, palpi, antennæ, and thorax fuscousgrey; terminal joint of palpi grey-whitish, anterior edge dark fuscous. Abdomen grey, anal tuft pale greyish-ochreous. Legs dark fuscous; posterior tibiæ and apex of all tarsal joints whitish. Forewings moderate, costa moderately arched, apex rounded, hindmargin very obliquely rounded; whitish fuscous, very densely and finely irrorated with dark fuscous; a few scattered black scales: cilia whitish fuscous, on lower half densely irrorated with dark fuscous. Hindwings grey, somewhat darker towards apex; cilia whitish-grey, with a darker line near base. A very dull-coloured and inconspicuous insect. Christchurch, in December; three specimens amongst bush, in indifferent condition. 12. Gymnobathra, Meyr. Head loosely scaled, sidetufts large, appressed, projecting over forehead. Antennæ in male moderate, moderately and evenly ciliated (1), basal joint rather elongate, moderate, without pecten. Palpi moderate,
