The fifth posterior areolet (reckoning from the base of the wing)

Var. 1. The fifth posterior cell is divided at the base. 



Var. 2. The fifth posterior cell is divided in the middle. 



Var. 3. The second submarginal cell is subdivided by a little 

 forked cross-vein which forms an additional areolet. 



Var. 4. The second submarginal cell has three little additional 

 cross-veins united at one end, and forming two areolets.
