Face and head silver white, with central indistinct golden line to collar. Collar and thorax golden brown with a silvery line above patagia. Ground and forewing golden brown. Along the costa are four silvery fasciae edged with black, situated as follows: The first one a trifle more than one-fourth from base, outwardly oblique, nearly to middle of wing, curved toward costa. Second fascia a little beyond middle of costa, outwardly oblique, to middle of wing, curved toward costa. Third fascia is short one-fourth from apex, outwardly oblique. The fourth at the beginning of the costal cilia is short, inwardly oblique. A subbasal silvery streak from the dorsal margin reaching the fold one- fourth from base. An outwardly oblique silvery streak from middle of dorsal margin to fold. A second dorsal streak near inner angle to fold ending near the third costal fascia, edged strongly with brown scales at the point. On the middle of the wing, at apical fourth, is a cluster of bright golden scales, a blackish spot centered with silver just below the apex. Cilia along apical curve white, becoming dark gray along dorsal edge. Hindwing blackish brown, cilia dark gray. Abdomen gray, anal segment white. Legs white with brown shadings, and brown annulations on tarsal joint. Expanse, 8-8.5 mm" - Engel, 1907. |
