Male, female.—9–10½ mm. Head and thorax dark fuscous, sprinkled with ashy-whitish. Forewings narrow, costa hardly arched, hindmargin sinuate, very oblique; dark fuscous, irrorated with grey and ashy-whitish scales, especially on basal half and before apex, tending to form irregular transverse lines; sometimes an indistinct ochreous suffusion towards inner margin before middle, and above anal angle: cilia dark fuscous, extreme tips and base ashy-whitish. Hindwings dark fuscous; cilia dark fuscous, with a darker basal line.

Taken rather commonly amongst rough herbage near a swamp at Hamilton, in January.

Thorax smooth. Antennæ in male ciliated. Palpi moderate, porrected, second joint roughly haired. Forewings with costa in male simple. Hindwings broader than forewings. Forewings with 12 veins, 7 and 8 separate, 7 to hindmargin. Hindwings with 7 veins (normal veins 3 and 4 coincident), 4 parallel to 3, 5 and 6 separate.

I cannot affirm for certain that this genus is correctly located; it is impossible to make out on the single specimen whether the lower median is truly pectinated or not, but in other respects it seems to have some affinity with the group of Strepsiceros, though the antennæ are not notched.

Parva, alis ant. dilute griseo-ochreis, fascia antica subcurva, altera postica inferius dilatata, tertia subapicali, macula costæ media alteraque apicis saturate fuscis; post. griseis.

Male.—10½ mm. Head, thorax, and abdomen fuscous, mixed with pale greyish-ochreous. Palpi grey-whitish, externally suffused with fuscous. Antennæ dark fuscous. Legs dark fuscous, posterior tibiæ grey-whitish, apex of joints obscurely pale. Forewings very narrow, costa hardly arched, hindmargin nearly straight, extremely oblique; pale greyish-ochreous, obscurely strigulated with grey, and with scattered dark fuscous scales; base mixed with dark fuscous; two small dark fuscous spots on costa near base; a moderately broad slightly curved dark fuscous fascia from ⅓ of costa to ⅖ of inner margin; a small dark fuscous spot on middle of costa; a dark fuscous fascia from ⅔ of costa to anal angle, upper half narrow, lower half very broadly dilated; a narrow somewhat irregular dark fuscous fascia from ⅚ of costa to middle of hindmargin; a small dark fuscous apical spot: cilia ochreous-whitish mixed with grey. Hindwings rather dark grey; cilia grey, tips paler.

A very distinct species, in form and marking somewhat resembling Eurythecta robusta.
