legs arc very long and unusually slender; the outer tibial spurs 

 arc almost as long as the inner, except in Agdistis and some 

 species of .Undid. In the genera with cleft wings veins 5 and 

 G are necessarily extremely short, but always present. 



Ovum more or less oval, smooth. Larva rather short, with 

 more or less developed fascicles of hairs. Pupa sometimes 

 hairy, attached by tail or in a slight cocoon above ground. 



The phytogeny is expressed in the diagram.
