 also the whole of the second posterior cell, and then, by bending 

 slightly outwards, the greater part of the third posterior cell ; a 

 brown streak also begins at the inner cross-vein, passes over the 

 basal part of the discal cell, passes longitudinally through the 

 fourth posterior cell, nearly tilling it, and spreading over part of 

 the fifth posterior cell also, and on attaining the border extends 

 each way, meeting on one side the hind part of the apical spot,
