About Leucochlaena oditis Hübner
Technical description and variation of L. oditis Hbn. (= hispida H. G., pilosa Bsd., hirta Dup. nec Hbn.) (29 c): Forewings are deep olive brown, with all veins colored whitish. The inner and outer lines are broadly whitish, each with a dark line running through their center. The inner line is outwardly oblique; the outer line is outcurved above the middle and oblique below the middle, and it emits pale tooth-shaped marks along the veins to the submarginal line. The submarginal line is broad, whitish on its internal side and rufous or brownish on its external side, and is toothed between the black marginal lunules. This line is preceded by black wedge-shaped blotches that lie between the teeth of the outer line. The claviform stigma is brown and edged with black; the upper stigmata are pale ochreous, finely outlined with black, and the orbicular stigma has a reddish center. The fringe has a brown basal half and an ochreous outer half. Hindwings are dull whitish, becoming brownish grey towards the termen, and have a dark outer line. Specimens collected from chalk terrain at Portland, South England are much paler, and form the aberrations pallida Tutt and obsoleta Tutt. Aberration pallida Tutt is pale grey with a faint brown tinge, has a whitish costa, a broad white submarginal line that matches the color of the fringe, and has hindwings and fringe that are almost entirely white. Aberration obsoleta Tutt is dull grey with barely any paler markings. Aberration hispanica ab. nov. (29 c, d) differs by being smaller, with a yellower brown color; all its lines, veins, and markings are ochreous rather than white, except for the inner linear edge of the submarginal line. It is immediately distinguished by the lower half of the outer line being vertical instead of oblique, running in a straight line with the inner edge of the reniform. Larvae are yellowish green or brownish, with pale dorsal and subdorsal lines that have dark edges, and a broad, yellowish white spiracular line. The wingspan of this species ranges from 28 to 36 mm.
