from upper angle and on a stalk of J of 6 ; 8 touching upper median at J, 
but not anastomosing with it. 
In one specimen of 0. nuda I find that the right fore wing has 10 free, 
and thus forms no areole, while the other wing is quite normal ; its hind 
wing has vein 5 nearer to 4 than 4 is to 3, and the stalk of 6 and 7 is not 
quite as long as normally. In 0. nigricosta the free part of 7 and 10 comes 
from £ of the areole, and thus places it near the genus Pirga, from which 
it differs, however, in the shorter stalk of 6 and 7 of the hind wing. 
1. a. Both wings white 
b. Wings not white 
2. a. Veins of fore wings dark 
b. Veins of fore wing of ground colour 
3. a. Fore wing with scaling rather dense ; ground colour 
of both wings maize yellow (IV) ; hind wing with 
the veins rather light 
b. Fore wing with the scaling rather thin ; ground colour 
of both wings cream colour (XVI) ; veins of hind 
wing almost as dark as in fore wing
