Diy. n. 
Mediastinal vein ending at about three-fourths of the length of the 
wing, connected with the subcostal by a veinlet near its tip; subcostal 
ending at beyond five-sixths of the length; radial springing from the 
subcostal at a little before the tip of the mediastinal ; cubital springing 
from the subcostal at a little before the base of the radial to which it is 
parallel ; first externo-medial springing from the cubital, forming near 
its base an almost right angle, forked at two-thirds of its length, joined 
with the third externo-medial by two veinlets, and the angle formed by 
the outer one of these two veinlets emits the second externo-medial vein, 
and has its hind side very oblique and more than twice the length of its 
fore side; third externo-medial connected with the subanal by a trans- 
verse yeinlet, which is opposite the base of the discal areolet.
