6 NOVITATES ZOOLOGICAE XXVI. 1919. 



all the specimens of this group of Castnia have two distinct pale bands on the 

 underside of the fore\\ing, and if in drucei or in the forms of alymnius other than 

 aiymnius aiymniits the outer macular band shows through in some specimens, 

 it is the exception and not the rule. (It is present above in the ?? of all.) 

 The Tring Museum possesses 7 specimens of alymnius atymniiis : 

 1 (J Espiritu Santo (ex coll. Fruhstorfer) ; 1 $ Rio Janeiro (the subapical 

 macular band above is much more obsolete than in the other races and in 

 drucei) ; 3 <JcJ Brazil, Westin (ex. Mus. Holm, ex coll. Felder) (type) ; 2 <J(J ?. 



Castnia (Castnicmera) atymnius humboldti Boisd. 



Castnia humboldti BoisduTal, Spec. Gen. Lipid. Hit. p. 528 (1874) (Columbia). 



The Tring Museum possesses 8 specimens of this race as follows : 



4 cJcJ, 2 ?? Rio Dagua, Columbia (W. Rosenberg) ; 1 S Bogota (Childs) ; 

 1 <J Sta Fe de Bogota. 



Castnia (Castniomera) alymnius futilis Walk. 



Castnia futilis Walker, Cat. Lepid. Ins. Brit. Mus. vol. 7. p. 1581 (1856) (Nicaragua). 



Owing to the confusion of futilis by Westwood and Druce, and because it 

 has never been figured, Messrs. Houlbert and Oberthiir ignore it entirely as a 

 nomenclatorial unit, though under drucei they go fuUy into its history. I have 

 compared the type carefully and have come to the conclusion that it is the 

 same as Boisduval's salasia, which it therefore antedates by eighteen years. 

 Strand's brunneata is rightly considerel by Houlbert as a pale ? of salasia = 

 futilis, there are 2 <J<J at Tring of the same aberration. The series in the Tring 

 Museum consists of 34 specimens as follows : 



1 cj Panama, October 1896 (W. Rosenberg) ; 5 JcJ Isthmus of Panama, 

 December 1907 (Pemberton) ; 2 SS Guapiles, Costa Rica, Jime (W. Schaus) ;
