Genus ODAGEA. 



Fcem. Corpus gracile. Proboscis brevis, gracilis. Palpi 

 porrecti, graciles, pilosi, caput paullo superantes ; articulus 3us 

 conicus, parvus. Antennae subpectinatae. Abdomen lineare, alas 

 posticas paullo superans ; fasciculus apicalis brevissimus. Pedes 

 gracillimi ; tibiae subfimbriata; ; posticae quadricalcaratae. Alae 

 amplae, subsquamosae, fere hyalinae, basi pilosae; anticae vix acutae, 

 margine exteriore convexo perparum obliquo. 



Female. Body slender. Head and thorax clothed with long 

 hairs. Proboscis short, slender. Palpi porrect, slender, pilose, ex- 

 tending a little beyond the head ; third joint conical, not more than 

 one-fourth of the length of the second. Antennae moderately long, 

 slightly pectinated. Abdomen linear, extending a little beyond 

 the hind win^s ; apical tuft very short. Legs very slender; tibiae 

 slightly fringed ; hind tibiae with four slender moderately long spurs. 

 Wings ample, very thinly squamous, pilose at the base, nearly 

 hyaline. Fore wings hardly acute ; exterior border convex, very 

 slightly oblique ; second inferior vein about four times further from 

 the third than from the first ; third very much further from the 

 fourth than from the second. 



The short palpi and the slender legs of this genus distinguish 

 it from Lcelia, to which it has most affinity.
