Body cinereous, underneath whiter. Antennæ testaceous ; thorax crested ? as the scales are mostry rubbed off this cannot however be positively asserted; wings incumbent ; primaries with a subcrenate edge ; inclining to ash-colored, clouded with black, with a subramose rectangular somewhat silvery spot, extending from near the base to the middle of the wing; between which and the apex is a narrow white wavy band, edged with black; and still nearer the margin a zigzag transverse black line; the secondary wings are plicatile, cinereous, and dusted at the apex with brown.
