NOVITATES ZOOLOOICAE XXVI. 1919. 3 



Preiss's insects cannot be finally splved yet. As, however, these Peruvian and 

 Bolivian ^<J differ immensely from Kollar's figure of the Brazilian 2 and the 

 habitats of the two are very far apart, I have preferred at present to keep them 

 as distinct species till we can compare Brazilian cjtj and Bolivian ??. Preiss's 

 figure agrees exactly with the 9 (Jc? at Tring. 



5 <J(J Buenavista, East Bolivia, 750 m. = 2,438 ft., August 1906— April 

 1907 (Jose Steinbach) ; 3 <J<J Yahuarmya, S.E. Peru, 1,200 ff., February and 

 March 1912 {H. and C. Watkins) ; 1 cj Sta Cruz de la Sierra, East Bohvia, 1905-6 

 (Jose Steinbach). 



Castnia (Amauta) cacica Herr.-Schaeff. 



Castnia cacica Hesrioh-SchsieflFer, Ausseur Schmett. pi. liv. fig. 143 (1854) (Central Columbia). 



In the case of this species I am convinced that Druce was wrong and Houl- 

 bert and Oberthiir right in separating two races of aicica, the typical one being 

 confined to Central Columbia. The Tring Museum has 5 specimens of cacica 

 cacica as follows : 



2 (J<J Columbia ; 1 3 Sta Pe de Bogota ; 1 ? ? ; 1 ? Bogota (Lindig coll., 

 ex coll. Felder). 



Castnia (Amauta) cacica procera Boisd. 



Castnia procera Boisduval, Spec. Gen. Lepid. Hit. p. 503 (1874) (Mexico). 



This form differs chiefly in the absence of the white discocellular stigma 

 in the forewings. 



There are at Tring 1 1 specimens as follows : 



1 $ Guatemala (Salvin, ex coll. Felder) ; 2 <?<?, 2 ?? Sixola River, Costa 

 Rica (W. Schaus) ; 2 cJcJ ? ; 1 <J S. America ! (loc. err.) ; 1 <? Carilla, Costa 

 Rica ; 1 (J, 1 ? Carrabianco, Costa Rica (Lankester). 



Castnia (Amauta) papilionaris amethystina Houlb. 



Castnia amethystina Houlbert, Etud. Entom. Comp. fasc. xiii. p. 54 (1917) (Panama). 



This form differs from papilionaris papilionaris by its small size and narrow 

 blue band on hindwings. The Tring Museum has one specimen, 1 <? Merida, 

 Venezuela (Briceno). 



Castnia (Amauta) papilionaris velutina Houlb. 



Castnia velutina Houlbert, Etud. Entom. Comp. fasc. xiii. p. 55 (1917) (Guayaquil ?). 



1 ? Maceo, Ecuador, 1905-6; 1 ? Zamora, Ecuador, 2—4,000 ft. (0. T. 

 Baron) ; 2 <J<J, 2 ?$ Ecuador. 



Castnia (Amauta) papilionaris affinis subsp. nov. 



This form is nearest to velutiim, but the ?? have the bands almost as broad 

 as in Westwood's figure of papilionaris papilionaris. The Tring Museum has 

 8 specimens as follows : 



3 <JcJ, 1 $ Yahuarmya, S.E. Peru, 1,200 ft., February— March 1912 (H. 

 and C. Watkins) ; 1 S Pozuzo, Huanaco, 800—1,000 m. = 2,600—3,250 ft. 

 (W. Hoffmanns) ; 2 ?? Chanchamayo, Peru ; 1 S Songo, Bolivia (Garlepp).
