Male, female.—80-86 mm. Forewings moderate, hindmargin slightly 
rounded, straight, or somewhat concave, more or less erenulate ; ochreous- 
brown; numerous dark grey or dark fuscous somewhat irregular shortly 
dentate strie ; a narrow dark fuscous fascia before middle, and a rather 
broader one beyond middle, more or less approximated, sometimes both cut 
below middle by a broad biconcave bar of ground-colour ; included median 
band often grey; a small black transverse discal spot; often first fascia 
preceded and second fascia followed by a narrow whitish or white fascia; a 
very obscure whitish subterminal line. Hindwings moderate, hindmargin 
rounded, crenulate; light brownish-ochreous, greyer towards base and 
inner margin; numerous obscure incomplete dark grey strie. 
Extremely variable, yet not so as to justify so long a list of synonyms. 
Wellington, Christchurch, Mount Hutt, Dunedin, Lake Wakatipu, and 
probably throughout the islands, abundant from December to February ; 
fifty-two specimens. Mr. R. W. Fereday informs me that this species is 
now scarce near Christchurch, where it was formerly very abundant, having 
been nearly exterminated by the increase of birds.
