Div. H H. 



The first and the second longitudinal veins are simple, and the 

 first is undulating ; the third has a rather long oblique vein, where- 

 by it joins the fourth ; the fourth has no areolet, but is forked, and 

 its lower branch is shortly again divided; the fifth, a little before 

 one-third of its length, sends forth a branch, which at first forms an 

 acute angle with it, but afterwards inclines downwards, and joins 

 the fourth at the first division of the latter : in its course it sends 

 forth two branches ; the first of these is forked, and its upper divi- 

 sion is shortly connected with the fifth vein by a very short cross 

 vein ; the second branch is simple.

Div. 1 1. 



The first and the second longitudinal veins are simple; the 

 third has a short, nearly upright cross vein, which joins it with the 

 fourth ; the fourth has no areolet, but it has a cross vein which con- 

 nects it with the lowest branch of the fifth, and it is afterwards 

 forked ; the middle of this connecting-vein sends forth a branch to 

 the tip of the wing ; the fifth, at half its length, has a branch which 

 descends into the wing, and there forms an angle and runs parallel 

 to the fifth vein, and is afterwards forked ; its upper division is con- 

 nected with the fifth vein by a very short upright cross vein ; its
