The area between Cuza, Cuıp and the hind margin of 
the wing is named the cubital area. In the Palparid- 
group Cu2 runs as a free and not coalescing nervure 
to the margin of the wing; but in all the other forms of 
the Myrmeleonidae — as far as I know — Cu2 coalesces 
with 7A for some distance. In Dendroleon the basal part 
af Cu2 is easily observable; in the Macronemurini the

basal part has only the form of an oblique crossvein be- 
tween Cuz and JA. Close to the base of the wing and 
almost at that point where Cw forks an oblique, forwardly 
directed crossvein is emitted from Cu. This vein crosses 
M and continues in a still more oblique direction until 
it coalesces with R. In the hindwing Cw also forks close 
to the base of the wing. Cuwz is free and runs into the 
hind margin a little before the point where M 2p ends. 
Cu2 only touches JA close to its base, or it coalesces 
with 7A for some distance. In the forewing of the Pal-
