with four brown clouds : on small crossrvein, at origin of third vein, 

 at termination of auxiliary vein, and on cross-veins at distal end of 

 second basal cell.

 auxiliary vein inward to third vein at a point posterior to the small cross- vein, 

 and barely, or not, connected with one on the latter ; and, finally, a system of 

 more or less connected clouds occupies the apical one-third of the wing, only
