15mm. The male antennae are strongly ciliate as in emiliusalis and ventralis,
and the male genitalia are also similar. The main distinction is in the facies
of the forewing where the fasciation is more sharply defined than in emiliusalis
but without the contrasting zones of pale and dark of ventralis. The
postmedial is more irregular, slightly more basal; there is no oblique medial
band or only a very faint, diffuse one. There is a prominent white fleck in the
same position as that of ventralis but not as long. The dark shading of
the submarginal zone is more even, not more intense over the anterior half.
