Epichorista elephantina Meyr.
♀. 23 mm. Forewings more pointed than ♂, costa more arched, termen more oblique (thus, with smaller size, showing some tendency to reduction). Hindwings rather dark grey (in ♂ whitish).
Arthur's Pass, January (Hudson). The species was described from a single male taken in the same locality, and appears to be rare, though other males have been recorded.
