 dark spots above on meso- and metathorax. Abdomen brownish; legs 

 pale yellow. Wings very pale yellowish hyaline, the main veins lightly 

 spotted with black, but the margin of wing unmarked. The first gradate 

 series broken, the posterior part and the median part clouded with brown, 

 so that each wing appears to have two brown spots near middle; in hind 

 wings the veins all pale and unmarked. In fore wings the median is not 

 bent toward cubitus, so that the basal cross-veins there are of sub-equal 

 length. In the hind wings the first fork of the radial sector is as far out 

 as the fork of median vein.
