 Poh/hniiuio CnASiBFAi)^, Can. Ent., VI, 1S74, j.. 24H.

 typo, has the following- characters: Labial palpi recurved, \(>rv long, 

 slender, second joint slightly thickened with smoothly appressed scales, 

 terminal joint as long or longer than second, pointed. Forewings 

 narrow, elongate, caudate, the costal and dorsal edge both slightly 

 excised before the tip, which is produced and hooked a little down- 

 ward, l!^ veins, 7 and 8 ver}' long-stalked; or 11 veins, 7 and S coincident. 

 Hindwings nearly as broad as forewings, elongate, apex produced, ter- 

 men sinuate; 8 veins, 3 and 4 shortstalked, 5 tipproximate to 4, i\ and 

 7 longstalked; transverse vein nearl}- ol)solete. 



This characteristic genus has been recorded ))y Lord Walsingham 

 from the West Indies and from Africa; in America it is a southern 

 genus attached to leguminous food plants. 



Only three species have been described from this continent; these 

 may l)e separated as follows: 



Forewings with lontritmliiial sitindle formed white strealv, vein 8 present • 1 



Forewings withi )Ut such st iiak, vein 8 absent .). sexstrigella, p. 840

Of this easih" recognized and elegant species the U. S. National 

 Museum possesses two specimens labeled by Lord Walsingham and a 

 good series bred by the writer in the District of Colum])ia. In locali-
