14. GoMPHAESCHNA Selys 
These are small brown darners of rather secretive habits and of very 
local distribution. The stigma of the wings is short, with only two 
cells bordering it behind. Between the two thickened antenodal cross 
veins there are usually but two weak ones. The triangles are divided 
by a single cross vein. There are but two cubito-anal cross veins. A 
single row of cells is subtended by the radial planate. The anal loop 
is small, enclosing usually but four cells. This is a large array of vena- 
tional characters setting off this genus from all our other Aeschnines, 
allying it somewhat with the preceding subfamily (as the generic name 
suggests), as does also the forking inferior appendage of the male ab- 
domen. 
The single species is restricted in its distribution to the eastern states. 
Its nymph is still (1928) unknown.
