60 STUDIES IN AUSTRALIAN NEUROPTEKA, ii., 



Genus S T E N o L E o N, n.g. 



Wings excessively narrow, pointed; in forewing, lis arises well 

 beyond brace of cubital fork, and is somewhat bent at the origin 

 of its first descending branch; 5-6 cross-veins in radial space in 

 forewing; oblique vein lying about under level of origin of Rs. 

 No Banksian line present. Costal space very narrow in fore- 

 wing, but widened near base in hind wing by the upward arching 

 of C. 



Legs moderately long; first and fifth tarsal joints about equal; 

 2nd- 1th very short; spurs present, short, about as long as first 

 tarsal joint. Abdomen slender, rather sliort. 



Genotype, St. fieldi, n.sp. 



This genus, which appears to have no near allies except, perhaps, 

 the African .Vemoleon, is a highly reduced off'shoot from the main 

 Distoleontine stock, easily distinguished from all other Australian 

 genera known to me by the combination of characters given 

 above.
