Fam. DREPANULID^. 

 Gen. DEYOPTERIS Grote. 

 Antennae bi-pectinated in the male with short and thick set branches 

 simple, or nearly so, in the female. Palpi short. Wings broad; superior 

 pair obtusely falcate with the exterior border convex near the middle; 

 third inferior vein twice or thrice further from the fourth than from the 

 second. Legs pilose. Abdomen shorter than the Inferior wings. 



I have enlarged the diagnosis of this genus since its first publication 

 in the Proceedings of the Academy of Natural Sciences, and think I 

 have rendered its characters more appreciable. 



The species included under it differ from those under Platyiiterix Lasp. 

 by their obtusely falcate superior wings which are nearly straight along 

 the costa and convex near the middle of the exterior border; by their 

 bright colors, somewhat stouter bodies and legs, the latter densely clothed 

 with hairs, while in Platypterix Lasp., the legs are slender and naked. 

 The type of this Genus is D. rosea Walker, C. B. M. VIII (see Plate 3, 

 fig. 1 9 ) and the synonyms to be observed of that species are Cilix avieri- 

 cana II. S. Lep. Exot. p. 60, fig. 470, and Flati/pterix formula Grote, 

 Proc. Acad. Nat. Sci. Phila. 1862, p. 60. 



D. marginata Walker belongs to this genus.
