The first and the second longitudinal veins are simple ; the 

 third has a short cross vein that joins the middle of the areolet on 

 the fourth ; the fourth has two short cross veins that form the sides 

 of the areolet, and the second of these sends forth a branch to the 

 tip of the wing ; the fifth, at two-thirds of its length, sends forth a 

 branch, which descends a little into the wing, and there forms an 

 angle, and passes onwards till it forms another angle, and thence 

 bending downwards joins the inner upper angle of the areolet above 

 mentioned : during its course it sends forth three branches, of which 

 the first is forked, the second is simple, the third forms the upper 

 side of the areolet and is afterwards forked.

Div. E E. 



The first and the second longitudinal veins are simple ; the 

 third has a short slanting cross vein, which joins the fourth ; on the 

 fourth is no areolet, but only a very short cross vein connecting it 

 with the lower division of the fifth; the fifth, just before half its 

 length, sends forth a branch which runs for a while nearly parallel 

 to it, and joins the little vein which springs from the fourth : during 

 its course it sends forth three branches ; the first of these has an ob- 

 lique fork, which joins the fore border of the wing a little after the 

 tip of the fifth vein ; the second is simple ; the third springs from 

 the angle of the junction with the little branch of the fourth vein, 

 and is forked.
