This very handsome insect has occurred in the South Island at Nelson, Christchurch, Akaroa and the Otira Gorge.
The expansion of the wings is about 1¾ inches. The fore-wings are creamy-white; there is a small dark brown mark at the base, a broad transverse wavy brown band before the middle, a very large four-cornered irregular brown mark beyond the middle, one of its corners touching the apex and the other the tornus; the termen is shaded with pale grey, and there is a series of faint brown marks on the costa and dorsum. The hind-wings are dull white, darker towards the termen; there are two very faint transverse lines.
The perfect insect appears from November till February. It is a very rare species.
Described and figured from a specimen in Mr. Fereday's collection.
