? . Head black, with flat black scales forming a large patch on 

 each side, then a small grey patch, another small black one, and then

 ones ; on each side in front is a short line of white scales, and the pro-

 the second posterior cell, its base nearer the base of the wing, its stem 

 less than half the length of the cell, stem of the second posterior cell 

 as long as the cell ; posterior cross-vein longer than the mid, about 

 one and half times its own length distant from it ; first longitudinal
