When perfect, it isa little more than three-tenths of an inch long, of a tawny-brown color clouded with dull white, and thickly punctatedwith black dots. The wing-covers have on their inner margin,near the tip, a small white spot, and another larger one oppo-site this on the outer margin; but the wings are not spottedwith black as in No. 127.
