Table of Genera. 



1. Anal vein of fore wings ends much before the origin of the tirst foik 



of radial sector, often before the radial sector itself ; six or more 



transversals basad of the radial sector ; pronotum 



broad ( Myj-meleo7ii) 2. 



Anal vein of fore wings ends as far out or often farther than the 

 origin of the first fork of radial sector, usually less than six cross 

 veins basad of radial sector ; pronotum often more 

 slender ( Deiidroleoiii) 4. 



2. Legs very short and stout, very hairy ; tarsus I. mucli shorter than 



tibia I., large species Acaiithaclisis. 



Legs much more slender, not very hairy, tarsus L scarcely shorter 

 or usually longer than tibia L, usually smaller species 3. 



3. Spurs on leg \. scarcely longer than first tarsal joint ; in hind wings 



usually three or four cross veins basad of radial sector ; tarsus I. 

 about as long as tibia L; hind wings quite narrow, without large 

 spots Myrineleon. 



Spurs on leg L as long as first three tarsal joints ; in hind wings 

 usually but one cross vein basad of radial sector ; tarsus L shorter 

 than tibia L; hind wings quite narrow, without large 

 spots Psammoleon. 



Spurs on leg \. as long as first two tarsal joints; in hind wings 

 about two cross veins basad of radial sector; legs very slender; 

 tarsus L shorter than tibia \.\ antennae very slender, scarcely 

 clavate ; hind wings broad, with large spots Glemiriis. 



4. No tibial spurs ; first tarsal joint of leg L as long as next two ; in hind 



wings the cubital fork runs parallel to anal for some 



distance Maracanda. 



Spurs present 5. 



5. In hind wings cubital fork is very short, the anal bending down and 



not running parallel to the fork ; usually but one cell crossed 

 basad of radial sector in fore wings ; legs very slender ; spurs 

 slender; first tarsal joint nearly as long as next three; pronotum 



slender ; wings with large spots Deiidroleon. 



In hind wings the cubital fork runs parallel for some distance to 

 the anal vein; spurs stouter; legs stouter; no large spots on 

 wings 6.
