(Plate [X]., fig. 32 ♀.)
This species has occurred at Wellington in the North Island, and at Lake Wakatipu in the South Island.
The expansion of the wings of the male is 1⅛ inches, of the female 1⅜ inches. The fore-wings are dull slaty-grey, with a slightly paler central band; there is a fine oblique wavy transverse line at about one-fourth, another at about one-half, and indications of a third at about three-fourths; numerous minute black streaks are thickly scattered over the wing, especially near the base and the termen; the outline of the termen is very slightly scalloped. The hind-wings are pale grey, darker near the termen. The body is very dark slaty-grey. The antennæ of the male are not bi-pectinated.
The perfect insect appears in January, and is attracted by light. It is a scarce species.
