About Bityla defigurata Walker, 1865
Walker's original description of the female of Bityla defigurata is as follows: The species is cinereous-brown. The head and fore tegulae of the thorax are dark brown. The palpi are dull ochraceous, fringed beneath, obliquely ascending, and extend a little higher than the vertex; the second joint is mostly black on its outer side, while the third is elongate-conical and around one-third the length of the second joint. The abdomen is brownish-cinereous, extends rather beyond the hind wings, and has an ochraceous apical tuft. The wings are shining with an aeneous tinge. The fore wings have several indistinct brown lines made up of lunules, and the orbicular and reniform marks have indistinct brown borders. The hind wings are slightly more cinereous than the fore wings. The body length is 10 lines, and the wing length is 22 lines. This species is endemic to New Zealand, where it occurs in both the North Island and the South Island.
