fuscous, median ring of tibiæ and apex of all joints whitish-ochreous. Forewings moderate, costa gently arched, apex rounded, hindmargin oblique, hardly rounded; dull fuscous, mixed with darker and lighter; the lighter tint appears to form an obscure transverse fascia before middle parallel to hindmargin, and a curved transverse line from ¾ of costa to before anal angle; a tuft of dark fuscous scales beneath fold at ⅓; an arched dark fuscous mark in disc beyond middle; hindmargin and apical fourth of costa obscurely spotted with darker: cilia fuscous, with a darker line. Hindwings dark fuscous, somewhat lighter towards base; cilia fuscous, with a cloudy darker line. Conspicuously distinct by its deep fuscous colouring. Wellington, in January; two specimens. 10. Lathicrossa, n. g. Head with appressed scales, sidetufts moderate, loosely spreading. Antennæ in male moderate, strongly serrate towards apex, very shortly ciliated (¼), basal joint moderate, without pecten. Palpi moderately long, second joint not exceeding base of antennæ, thickened with dense appressed scales, terminal joint as long as second, rather stout, curved. Thorax crested posteriorly. Forewings moderate, apex obtuse, hindmargin oblique. Hindwings as broad as forewings, trapezoidal, hindmargin slightly sinuate, cilia 3/5. Abdomen moderate. Posterior tibiæ with short rough hairs above. Forewings with vein 7 to costa, 2 from rather before angle of cell. Hindwings normal. Allied to Gymnobathra, from which it is distinguished by the very short ciliations of the antennæ, and the thoracic crest. The single species is confined to New Zealand. 24. Lath. leucocentra, n. sp. Minor, alis ant. saturate fuscis, maculis costæ duabus parvis serieque punctorum marginis postici albido-ochreis, punctis disci tribus niveis; post. saturate fuscis. Male.—15 mm. Head whitish-ochreous, suffused on crown and forehead with dark fuscous. Palpi whitish-ochreous, externally sprinkled with dark fuscous, anterior edge marked throughout by a slender dark fuscous line. Antennæ dark fuscous. Thorax and abdomen dark fuscous, with a few whitish-ochreous scales. Legs dark fuscous, central ring of tibiæ, hairs of posterior tibiæ, and apex of all joints whitish-ochreous. Forewings moderate, somewhat dilated, costa gently arched, apex obtuse, hindmargin oblique, almost straight, very faintly sinuate beneath apex; dark fuscous, with irregularly scattered whitish-ochreous scales; a very small whitish-ochreous spot on middle of costa, and a rather larger transverse spot on costa at ¾, giving rise to a very faint curved line of whitish-ochreous scales
