THE WINGS OF MYIODACTYLID.E 



193 



veins of the subcosta are forked, and sometimes they are connected by 

 cross-veins. Many cross-veins are present in the other parts of the wing, 

 excepting the subcostal area in which they are lacking. In the outer third of 

 the wing the cross-veins are reduced in number, consisting chiefly of a series 

 of gradate veins. Many definitive accessory veins have been developed 

 upon the radius and upon the veins back of this vein ; the tips of most of 

 these are forked. The marginal accessory veins form a quite regular 

 border. 



The media is two-branched in both wings. In the fore wing the medial 

 fork is a little beyond the first fork of the radial sector in the specimen 

 figured, but it varies slightly in different individuals. In the hind wing the 

 medial fork is quite near the base of the wing; it is not, however, quite so 

 near the base of the wing as it appears to be in this figure; for, owing to a 

 fold in the wing, the base of media is concealed by the base of radius, which 

 overlaps it. A result of this overlapping of the base of media by the base 

 of radius is that the first radio-medial cross- vein appears to join the radius 

 instead of joining media, as it really does. 



The cubital fork is near the base of the wing in both fore and hind wings ; 

 and the anal veins are much branched.

{p) THE WINGS OF THE MYIODACTVLID.'E 



The type of this family is Myiodactyhis osmyloides, an Australian species 

 described by Fr. Brauer in 1 866 . This species I have not seen ; but through 

 the kindness of Mr. Nathan Banks I have been able to study a closely 

 allied species, Myiodactyhis pubesceiis, the wings of which I figure here (Fig. 

 189). This species is from Port Darwin, Australia.
