Hahltat. — Suapu I'e, Venezuela. 



Types.— (^'Ai. No. 8421, U.S.N.M., and in collection of the author. 



As indicated 1)V the venation of the fore wing, this species also 

 belongs to the same generic section as the latter. Superficially it 

 bears considerable I'esemblance to the species described by Druce under 

 the name of dalfha., a species belonging to a different generic section. 



Of this splendid family this is the most beautiful species known to 

 me, and I therefore name it after my mother. 



ARGYRCEIDES CERES Druce. 



Habitat. — Suapure, Venezuela. 



It has been found advisable to place this species of Argyroeides at 

 the head of those taken, owing to the discov^ery of a species belonging 

 to a new generic section.
