_Upper Side._ Head greyish brown. Antennæ strongly pectinated. Thorax and abdomen greyish. Anterior wings with a bar rising near the middle of the anterior margin, continued along the posterior wings parallel with the external edges, and ending near the abdominal corners; the inner part forming an equilateral triangle. The outer part of this triangle is ash colour, the inner part pale brownish grey, but darker than the rest of the wings. The tips of the superior wings are adorned with a small eye, the lower part of which is black, and the upper part white; from whence a faint white serpentine line runs to the very extremity of the wing. The spaces between the ash colour mentioned above, and the external edges of all the wings, are filled up with light brownish grey, appearing as if powdered thinly with black dust. A small narrow black line runs along the external edges of all the wings, which, beginning at the abdominal corners and ending at the tips, appears as if broken or interrupted just below the eyes. A narrow ash-coloured bar begins on the posterior edges next the shoulders of the superior wings, which, running towards the tips, suddenly turns off, and ends on the anterior edges about half an inch from the shoulders. On the middle of the posterior wings is an ash-coloured crescent, verged at top with black; and about a quarter of an inch above this is another crescent, larger and much fainter, running from the anterior to the abdominal edge, and ending at the extremity of the body. _Under Side._ All the parts on this side are nearly of the same colour as on the upper, but not quite so distinct and bright. The angular bar on the anterior wings next the shoulders, and the faint crescent on the posterior, not being discernible. The margins of all the wings are entire; the superior ones being hooked at their tips.
