neuration, composed of most delicate and irregular veinlets, The 
wing is also furnished with a large number of larger and smaller 
discolored spots, the surfaces of the larger ones irregularly elevated. 
The vena mediastina is simple and straight; the vena scapularis 
sends out two branches from its upper side, the first of which does 
not reach the border but loses itself in a congeries of minute veins, 
while the second, branching again quite near its origin, supports 
the tip of the wing ; the vena externo-media occupies the middle 
third of the wing, and divides once near the base; each branch 
is straight and forks again, the upper one a little nearer the border 
than the second divarication of the vena scapularis, the lower still 
nearer to the margin; the vena interno-medi 
terspace between the vene scapularis and externo-media; the others 
llow in succeeding interspaces. The two other large spots are 
found in the same interspaces with the upper two of the inner row, 
and are situated about half way between them and the border. 
The smaller spots appear to be less regularly distributed ; they are 
usually round, but sometimes oval or elongated ; there are three at 
equal distances from each other in the lower outer interspace =
