able, by using photographic enlargements and colored ink, to trace 
out the veins belonging to each of the three wings. This has re- 
sulted in a composite picture of a fore wing (based on two wings, 
one of which is isolated from the others) and a composite picture 
of the two hind wings. Of course, technique cannot restore the 
portions of the wing which are missing in the unpigmented areas. 
However, it is possible, because of the simplicity of the venational 
pattern, to restore with confidence the general venational pattern 
in the missing areas. 
The fore wing margin is very slightly concave, the wing being 
broadest beyond the termination of the subcosta; in contrast, the 
anterior margins of wings of most Calaneurodea are straight or
