Original description, Walker 1864
Cryptolechia undulatella.
Foem. Cana, robusta, squamosa; palpi extus fusci; antennae :nigrae; pedes breves, validi, tibiis posticis fimbriatis; alae anticae vitta latissima fusca antice diffusa postice concisa undulata lineam transversam undulatam canam includente; punctis marginalibus nigris; posticae aneo-cinereae.
Female. Hoary; stout, smooth, squamous. Palpi slender, twice longer than the breadth of the head, mostly brown on the outer side; third joint setiform, nearly as long as the second. Antennae black. Legs short, stout; hind tibiae fringed. Wings rather broad. Fore wings rounded at the tips, with a very broad brown stripe, which is diffuse towards the costa and towards the exterior border, but is concise and undulating towards the interior border, which it almost reaches near the interior angle; a hoary deeply undulating transverse line near the end of the stripe; marginal points black; first point near the end of the costa, second apical; six along the interior border, which is straight and slightly oblique. Hind wings cinereous, with an aeneous tinge. Length of the body 5 lines [10.6mm]; of the wings 14 lines [29.6mm].

Subsequent description, Meyrick 1890
Lich. undulatella, Walk.
(Cryptolechia undulatella, Walk, 756.)
Male 18-21mm. Head, palpi, antennae, and thorax grey; antennal ciliations ¼. Abdomen brownish. Anterior legs dark fuscous; middle and posterior pair white, tarsi fuscous, posterior tibiae fuscous externally. Forewings elongate, moderate, costa gently arched, apex rounded, hindmargin straight, oblique; 7 to hindmargin; red-brown, becoming deeper on lower half; a rather broad white streak along costa from near base to near apex, attenuated to both extremities; a broad grey streak, sprinkled with brownish, along inner margin from base to anal angle, beyond middle forming a broad triangular projection upwards, reaching half across wing, thence abruptly attenuated; a darker transverse mark in disc at 2/3; a slender strongly outwards-curved whitish line from costal streak at 2/3 to inner margin before anal angle, indented above lower extremity, where it forms a small spot; a grey apical blotch, covering whole area beyond this line except a spot towards anal angle; a series of small dark fuscous spots along hindmargin and around apex: cilia light ochreous-brownish, with a white basal line. Hindwings fuscous, lighter and more ochreous-tinged anteriorly, hindmargin suffusedly darker; cilia yellow-whitish, with a grey line.
Sydney, New South Wales, in November and January; three specimens. Larva 16-legged, stout, cylindrical; dirty whitish, spots large, black; feeds in a stout gallery of silk and refuse along leaflets of Acacia decurrens, in October.

Lichenaula undulatella, Walk. (Cryptolechia undulatella Walker, 756; Lichenaula undulatella, Meyrick, 47.) Male, 17-20 mm.  Female, 23 mm. Mr. Illidge has a variety of the male in which the whitish costal coloration extends beyond middle of disc reducing the red-brown ground-colour to a minimum, and giving the specimen at first sight a very distinct appearance.
Brisbane: Mr. Illidge has found the larvae feeding in among the leaves of Jacksonia scoparia (Dogwood), also of Acacia. (Turner, 1898).

L. undulatella (Walk.) (Fig 22.20) has grey fore wings marked with brown; it occurs from northern Queensland to Victoria. The larva feeds on Acacia decurrens, A. melanoxylon and other wattles (Mimosaceae), and Jacksonia scoparia (Fabaceae), forming a tubular shelter among the foliage. (Common, 1990).
