strange to say, sends out 5 branches from its upper side, close to 
its base. Most of the branches ramificate dichotomically, till they 
are about half so distant from each other at the margin of the wing 
as on the middle of it. The outermost row of crossveins is not 
exactly parallel with the margin. The innermost row only consists 
of very few cross-veins. It must, however, be observed that I have 
only drawn the veins which I know for certain to exist, it is pos¬ 
sible that there are more veins than drawn in both cross-vein series, 
but the state of preservation of the wing does not justify the state¬ 
ment of a greater number of veins.

The distal part of another wing likewise belonging to a Mega- 
lomus further is at hand. Judging by the broad costal area we 
might suppose it to be a fore wing, but 1st radial branch appears as 
a radial sector from which the other radial branches (except the hind 
one, 8th), issue, and this is a specific hind wing peculiarity.

On account of the form and size of the wing (the preserved 
piece is 9 mm long) as well as the course and density of the longitu¬ 
dinal veins, it is not excluded that this wing might be the hind wing 
corresponding to the Megalomus densistriatus fore wing described above. 
This conception is confirmed by the observation that the most pe¬ 
culiar character of this latter: the median branches issuing from the 
upper side of the median stem, is also represented in this wing (by 
3 such branches). 
If I am right in the supposition that the wing at hand belongs 
to M. densistriatus , we must add to the characters of this species the 
fact that both fore and hind wings have a broad costal area which 
then would justify the establishment of a new genus to this species.
