Family Blephariceridse — The Net-Winged Midges 



Affathon elesantula. 



Moderate sized, elongate, nearly l:)are species with long legs and 

 rather wide, delicate wings. 



Eyes sometimes lioloptic in one or both sexes and usnally bisected 

 below the middle by a narrow, nnfaeeted line below which the facets 

 are smaller; three ocelli present. Antenna slender, composed of nine to 

 fifteen segments and clothed witli pnbescence. Month i)arts more or 

 less elongate, the femak^s with slender, flattened elongate serrate man- 

 dibles. Mosontum with distinct, broadly interrupted transverse suture. 

 Legs rather slender, the posterior pair longer than the others; tibia) 

 with or without spurs; pulvilli and empodium absent or nearly so. 

 Wings broad, bare, the anal angle projecting, almost always with a net- 

 work of delicate lines due to the creasing of the folded wings in the 

 pupal case. 



The adults are not common in most col k'ct ions but are often found 

 in large numbers near fast-flowing streams. I have found them chiefly 

 on the foliage of evergreens or on the sides of cliffs or rocks.
