The wingspan is 35-38 mm. The forewings are silvery grey, the base, a central irregular black edged band, a transverse discal stripe and the outer border are rather paler and greyer than the rest of the wing. There is a black dot at the interior angle of the cell, a disco-submarginal series, a series of marginal black lunules and a short oblique black apical line. The hindwings are shining sordid white, with a broad, pale brown external border.

The larvae feed on Quercus mongolica.
