, where it has been recorded from New South Wales. The wingspan is 8–16 mm. The forewings are reddish ferruginous, with black-and-golden-metallic markings and a small black basal patch, the outer edge moderately straight, indented in the middle, where there are a few golden-metallic scales. There is a narrow outwardly oblique golden-metallic fascia, from the costa at one-fourth to beyond the inner margin at one-third, sometimes hardly reaching the inner margin. An irregular black quadrate spot is found on the costa immediately beyond, reaching more than half way across the wing and there is a second, similar to first, golden-metallic fascia, not so oblique as the first, immediately beyond the quadrate spot, sometimes broken, from the middle of the costa to the middle of the inner margin. A small roundish ochreous-white spot is found on the costa at three-fourths, the lower half reddish tinged, reaching nearly half way across the wing and a golden-metallic patch of scales is found beneath, but slightly anterior. There is also a blackish elongate spot on the costa between the second fascia and a whitish spot and the hindmarginal area beyond is black. The hindwings are pale fuscous.''Proceedings of the Linnean Society of New South Wales''. 24 (1): 98.
