Genus Gomphaeschna Selys 



Adults. — Wings with upper half of arculus as long as the 

 lower ; M^ not making a sharp bend towards M^ at distal end of 

 the stigma; Rs not forked; only one row of cells between Rgand 

 the supplementary radius ; triangle with cross-veins ; supertriangle 

 and basilar space free ; anal loop consisting of 3-4 cells ; cubito- 

 anal cross-veins 2 ; anal angle of the hind wings dissimilar in 

 the two sexes, the anal triangle consisting of 2 cells in the male; 

 abdominal terga 4-7 with only one lateral longitudinal ridge per 

 segment on each side; inferior appendages of the male bifurcate. 



Nymphs of this genus have not been reared. The adults have 

 been captured in various localities but they are such strong fliers 

 that it is impossible to even guess at the probable habitat of the 

 nymph.
