The first and the second longitudinal veins are simple ; the 

 third has a slightly curved cross vein, which joins the fourth a little 

 before the areolet on the latter ; the fourth has two short cross veins 

 that join the lowest division of the fifth, and form the sides of the 

 areolet ; the second of these cross veins sends forth from its middle 

 a little branch to the tip of the wing ; the fifth, a little before two- 

 thirds of its length, sends forth a branch which is forked, and its 

 upper division has a very short vein, by which it rejoins the fifth at 

 the tip of the latter ; the lower fork is again divided, and its lower 

 branch forms the upper side of the areolet before mentioned.
