14. In fore wings the anal vein runs parallel to the cubitus for a 



long distance '. 15. 



In fore wings the anal vein does not parallel the cubitus; a diver- 

 gent cubital fork present 16. 



15. First tarsal joint much shorter than the fifth Creagris. 



First tarsal joint about as long as the fifth Protoplectron. 



16. Legs rather short and stout 17. 



Legs very slender, tibia about as long as the femur; no line in 



apex of fore wings 18. 



17. Spurs about as long as first two joints of tarsus together, 



Macronemurus. 

 Spurs as long as three or four tarsal joints together. Distoleon. 



18. Radial sector arises much before the cul^ital fork; spurs as long 



as three or four tarsal joints Acratoleon. 



Radial sector arises much beyond the cubital fork; spurs hardly 

 more than two tarsal joints 19. 



19. Claws very long, little curved, half as long as last tarsal joint; 



pronotum rather short Paraglenurus. 



Claws not one-half as long as last tarsal joint; pronotum long 

 and slender Indoleon. 



20. Legs short and stout; spurs much longer than basal joint of 



tarsus, which is short 21. 



Legs more slender; spurs but little longer than basal joint of 

 tarsus 24. 



21. Larger species; legs very stout and hairy; spurs much curved 



or even bent 22. 



Smaller species; legs not very stout; spurs but little curved; 

 costal area with but one series of cells Myrmec^lurus. 



22. Hind Avings with a double series of costal cells; antennae very 



long; veinlets before origin of radial sector in fore wing are 



crossed Stiphroneura. 



Hind A\angs with but one series of costal cells 23. 



23. Second and third anal veins in fore wing form a closed cell, 



Onclus. 

 Second and third anal do not form a closed cell ..Acanthaclisis. 



24. Branches of radial sector are bent to form a line or groove in 



apical part of the wing Nesoleon. 



No such lin(> of bent veins in apical part of wing 25. 



25. Fore wings with a double series of costal cells in middle of length; 



a single series at each end Weelius. 



A double series of costal cells only near the stigma 26. 



26. A series of (ionnecting veinlets just before the stigma; wings 



very broad at stigma Hagenomyia. 



No such series, perhaps one or two veinlets connected to others, 

 several may be forked 27. 



27. Some cross- veins before radial sector crossed; wings broad at 



stigma Callistoleon. 



No cross- veins before radial sector crossed; wings narrow through- 

 out > Myrmeleon.
