 longitudinal vein ; the second crosses the middle of the discal cell 

 and attains the hind border ; the third crosses the second basal 

 and the anal cell, and is merged in the light colour of the base of 

 the wing ; the centres and hind borders of the posterior cells are 

 also pale grey. The upper fork of the 4th longitudinal vein 

 emerges frem the upper corner of the discal cell as to separate 

 veins, the outer side of that cell forming a distinct angle. Siigma 

 dark brown, proportionately large, and there are trares of yellow 

 just before it and also in the basal cells ; halterts brownish 

 yellow.
