Clear pale lemon yellow. The antenna with the 4th to 9th joints very pale grey. Third joint very small, a little longer than broad, about half the length of the second joint. Fourth joint rather slender, the length of the 2nd and 3rd taken together. The fifth about one-quarter shorter, about the same width. The 6th, 7th and 8th subequal, about the same length as the 5th but rather broader. Wings hyaline, with a very slight shadow below the vein, very nearly nine times as long as the greatest width (·525 × ·06 mm., approximately). Marginal cilia moderately strong, the longest ·132 mm. There is a line of hairs running along the middle of the wing from the apex of the vein to near the apex of the wing ; between this and the front margin there is another line of about twelve hairs, rather irregular, and there are a few hairs irregularly placed in the apical area. Between the central line and the hind margin there is an irregular line of about eight hairs, but they are not the same on both wings. Hind wings free from surface hairs, except three or four at the extreme apex. The posterior cilia moderately stout, except the first three or four, the longest about ·1 mm.
