This species is smaller and slighter than argenteomaculatas, and differs from any previously described from our territory by the gilded primaries, which are as brilliant as those of Plusia verruca. Dull lilac or pinkish fuscous. Fore wings falcate, with a fine brown line on submedian fold. Between the subcostal vein and submedian fold the wing is covered centrally with large patches of dead gold. There are two brown costal patches, between which are double pale lilac marks, the inceptions of the transverse lines, of which the outer beyond the outer brown patch is alone continuous, broad, irregular. Some dead gold patches about the discal mark, which is finely margined with brown, pyramidal, bright gilded. Three similar bright gilded, triangulate, brown-edged spots, form part of the subterminal line opposite the ceil. Else the s. t. line is narrow and brownish, broadly margined by dead gold shading on either side. Hind wings pinkish fuscous. with orange fringes. Beneath fuscous, without marks; external margin of primaries touched with orange; the short fringes shaded with orange on both wings.
