Antennre : club slender, elongate, with a rather long and very 

 slender terminal crook. Palpi : second joint pressed close against 

 face, third joint minute. Fore wing rather produced at apex, 

 inner and outer margins subequal ; cell less than two-thirds the 

 length of costa ; vein 12 reaching costa well before end of cell; 

 upper discocellular minute, middle very long, lower very short ; vein 

 5 from very close to bottom of cell ; vein 3 equidistant from 2 and 

 4 ; vein 2 slightly nearer to end of cell than to base of wing. Hind 

 wing elongated, outer margin even ; cell short, not reaching half 

 across wing ; vein 7 shortly before end of cell, both veins curved at 

 the bifurcation ; discocellulars outwardly oblique ; vein 5 not 

 traceable ; veins 2, 3, and 4 all very close together, the lower 

 margin of the cell bent upwards at origin of vein 2. Hind tibiae 

 with two pairs of spurs. 



In the male the fore cox?e are conspicuously tufted. The only 

 differences between Pithauria and Pithauriopsis are that in the 

 latter the male is furnished with a pair of glandular spots on the 

 upperside of the fore wing between veins 1 and 2, and that at the 

 bifurcation of vein 7 of the hiud wing the veins composing the fork 

 are more curved ; this, however, is a character which for some un- 

 known reason appears to occur in correlation with glandular patches 

 or streaks on the fore wing. The female of aitchisoni has not been 

 described, but will almost certainly be found to have the veins at the 

 origin of vein 7 of the hind wing straight, so that vein 7 would 

 arise at an acute angle.
