Abdomen, not extending beyond the hind wings, attenuated towards the tip, slightly tufted on the back.

Legs, long, stout, densely pilose, hind tibiæ with long spurs.

Wings, ample, marginal denticulation obsolete.

Fore wings: Upper-side slightly concave along the middle of the costa, convex towards the tip and base, greyish-dove colour, slightly shot with a faint purplish tint, irrorated and clouded with ferruginous and purplish-brown scales; transverse lines and central shade purplish-brown; half-line angulated; inner and elbow-lines slightly sinuous and indented, and with pale outer margins; the pale margin of the inner-line rather broad, of the elbow-line narrow and vanishing towards the costa; indentations of elbow-line from the costa to the middle forming a profile of a human face; the space between the central shade and the elbow-line forming a band darker than the ground colour of the wing, but lighter than the transverse lines; the area between the elbow-line and the rather indistinct sub-terminal line clouded with ferruginous, interrupted by a purplish-brown shade crossing it below the costal area, and forming the upper part into a sub-costal patch, the part towards the apex of the angle formed by the costa and elbow-line being paler and but slightly suffused with ferruginous; the space between the inner-line and central shade (especially the part beyond the middle) paler than the general ground colour; stigmata obsolete, with two dusky specks, one on the upper end and the other on the inner side of the lower end of the reniform stigma; hind margin with a narrow dusky border and a row of dusky dots. Under-side, basal, third and sub-marginal and costal parts pale brownish-grey; intermediate space dark purplish-brown, with a central broad white band extending from the sub-costal nervure to the anal angle, and deeply indented at the sub-internomedial nervure.

Hind wings: Upper-side dark purplish-brown, with a median white band slightly shaded with pale violet; two white patches on the hind margin, the one being sub-quadrate and situated towards the posterior angle, the other triangular and situated near the anal angle; also a narrow white border extending from the anal angle to near the triangular patch; the white patches extending into the cilia, and slightly tinted with pale violet; clothed at the base with long greyish-dove coloured hairs. Under-side pale brownish-grey, a dark purplish-brown patch, with whitish outer margin at the anal angle; a transverse narrow dusky fascia crossing the middle of the wing, and another beyond the middle, and a very indistinct sub-terminal one; an indistinct dusky hunule or spot in the centre of the area between the first line and the base of the wing; two pale patches on the hind margin representing the white patches on the upper-side.

Expanse of wings, 2′ 6′'.

Habitat: Wellington, New Zealand.

I have named the insect after Mr. W. T. L. Travers, by whom it was presented to me, and who captured it in his greenhouse, at Wellington, in the autumn of 1870.

I am not aware of any other representative of the Catocalidœ family having been taken or seen in New Zealand.
