Head ochreous, with a dense spreading frontal tuft of long coarse hair.
Forewings rather broad, apex broadly pointed; ochreous irrorated with dark fuscous; three or four incomplete black strigae on apical 1⁄4: cilia ochreous, with a black bar marking apex of the wing.

[2] S. demissa is endemic to New Zealand and is found in the northern half of the North Island.
