Labial palpus black, extending forward; second segment mixed with greyish white on inner surface, slightly longer than diameter of eye; third segment about 1/3 length of second segment, greyish white at apex. Antenna with scape black on dorsal surface, greyish brown on ventral surface; flagellum brown, darker on basal several flagellomeres, cilia on ventral surface same length as diameter of flagellum. Thorax and tegula black, part of scales tipped with greyish white. Forewing relatively narrow, widened from base to distal 1/4, narrowed triangularly to rounded apex; ground coloration greyish brown, with greyish white scales; costal margin straight, greyish brown, mixed with greyish white, with six black dots evenly spaced from basal 1/3 to apex; termen obliquely straight, black; basal patch black, triangular, its outer margin with raised greyish white scales; with six raised black scale tufts on median 1/3 of wing, edged with greyish white scales; fringe black, mixed with greyish white near apex.
