margin of wing straight or nearly so, posterior margin 
regularly convex, the wing being broadest at about the 
middle; the costal space is much broader distally, so that 
the termination of R1 is very remote from the apex of the 
wing; area between Sc and R1 with 4 or 5 cross-veins; R1 
distinctly curved backward at its distal end; Rs and M 
diverging from R close together ; space between R1 and Rs 
with less than 10 cross-veins; between the basal branches

Sc, subcosta; Rl, radius proper; Rs, radial sector; M, media; Cul and Cu2, 
branches of cubitus; 1A, first anal. 
of Rs there are numerous cross-veins, but there are ap- 
parently none at all between the distal branches; Cul long 
and straight, with seven irregular distal branches; Cu2 is 
much more strongly developed, with eleven branches; 1A 
forked in both wings ; cross-veins present between Cul and 
Cu2. The specimen has the left fore and hind wings well 
apart ; the right wings are folded together, so that the veins 
are indistinguishable. The body is slender, being 30 mm. 
long, and 3 mm. wide ; no details of the head are preserved.
