[3][4] George Hudson illustrated and discussed the species in his 1928 book The Butterflies and Moths of New Zealand.

Antennae fuscous basal half dark purple-fuscous, above middle with a pale-ochreous band.

Forewings elongate-triangular, costa anteriorly nearly straight, posteriorly gently arched, apex obtuse, termen rounded, little oblique; dark purplish-fuscous, irregularly irrorated with pale-greenish scales : cilia purplish-fuscous, towards base darker.

Hindwings dark fuscous; a dull ochreous-orange streak through disc from near base to 2⁄3, extremity enlarged; a fine pale ochreous-orange suffused submedian streak obscurely indicated : cilia whitish-ochreous, with dark-fuscous basal line.

[5] George Hudson noted that the female moth appeared to mimic a bug when at rest or walking.

[6] It has been hypothesised that this is protective mimicry for the moth as the bug it imitates has an objectionable taste and odour.
