1. Four separate anal veins in the fore wing; in hind wings the anal 



is not connected directly to the hind margin, but to the second 



anal by a series of cross-veins (Palparini) 2. 



Two or three anal veins in fore wing; in hind wings the anal is 

 connected by cross-veins directly to the margin 4. 



2. Two or more series of costal cells near to base of wing Stenares. 



But one series of costal cells until near the stigma 3. 



3. Antennae not their diameter apart at base; the basal joint with 



long bristles Palpares. 



Antennae more than their diameter apart at base Tomatares. 



4. In the fore wings the second and third anal veins are separate, 



but connected by a short cross- vein; a line in apex of the 



fore wings (Dendroleonini) 5. 



In the fore wings the second and third anal veins are united for 

 at least one point 11. 



5. In the hind wings the anal vein runs parallel to the cubitus for a 



long distance, finally curving to the margin beyond the middle 



of wing Echthomyrmex. 



In hind wings the anal runs to margin in a normal manner 6. 



6. Legs very slender, spurs very long and nearly straight, the first 



tarsal joint about as long as the last Dendroleon. 



Spurs and legs shorter; first tarsal joint much shorter than the 

 last 7. 



7. Outer margin of wings barely sinuate 9. 



Outer margin of wings sinuate or excised 8. 



8. Many radial cross-veins are crossed; the venation very dense; 



outer margin of wings sinuate Episalus. 



Radial cross-veins not crossed; outer margin of wings excised, 



Periclystus. 



9. Many of the costals crossed; abdomen about as long as wings; 



cubito-anal cross- veins longer than anal cross- veins, 



Epicanthaclisis. 

 Few of costals crossed; abdomen much shorter than wings 10. 



10. Cubito-anal cross-veins shorter than anal cross- veins; venation 



irregular Layahima. 



Cubito-anal cross-veins longer than anal cross-veins; venation 

 fairly regular Glenoleon. 



11. One cross-vein before radial sector in the hind wings, 



(Macronemurini) 12. 



Three or more cross-veins before the radial sector in the hind 



A\dngs; antennae wide apart at base (Myrmeleonini) 20. 



12. No spurs to tibiae 13. 



Spurs distinct 14. 



13. Many costals forked; two series of anal cells for part of the 



way Chrysoleon. 



Costals simple; one series of anal cells; wings rather narrow, 



Compsoleon.
