12 NOVITATES ZOOLOGICAE XXVI. 1910. 



[Castnia (Athis) menetriesi Boisd. 



Castnia menetriesi Boisduval, Spec. Gen. Lipid. Hit. p. 511 (1874) (Brazil). 



Messrs. Houlbert and Obcrthiir consider this insect as a distinct species, 

 but if one examines the drawing even superficially it becomes at once apparent 

 that it is in reality only an extreme form of hegemon. My hegemon variegata 

 described above stands exactly intermediate between hegemon and menetriesi 

 in regard to the amount of black on the outer one-third of hindwing ; while on 

 the underside of fore wing the black markings are much more developed in mene- 

 triesi than in either hegemon or h. variegata ; menetriesi must therefore stand as 

 hegemon menetriesi. It probably came from the extreme south of Brazil.] 



Castnia (Athis) fabricii boisduvalii Walk. 



Castnia boisduvalii Walker, List Lepid. Ins. Brit. Mils, part i. p. 27 (1854) (Brazil). 



Messrs. Houlbert and Oberthiir declare that only males of this species are 

 known. They also appear to have had very few specimens for examination, 

 4 in the collection of M. Charles Oberthiir and 2 in the Paris Museum. The Tring 

 Museum possesses 2& 3o and 1 ?. The ? is exactly like the 2? of papaguya 

 Westw., but the forewings are much darker, almost as dark as in S hoisduvalii.

Castnia (Athis) fabricii papagaya Westw. 



Castnia papagaya Westwood, Trans. Linn. Sue. Land. 1877. p. 170. pi. xxx. fig. 6 (Papagaya). 



Messrs. Houlbert and Oberthiir treat this as a distinct species, but it is 

 only a larger and brighter race of boisduvalii. The Tring Museum has 11 

 specimens : 



4 33, 7 ?? Rio Grande do Sul. 



[Castnia (Athis) fabricii Swains. 



Messrs. Houlbert and Oberthiir regard this insect, known to us only by 

 Swainson's figure, as a distinct species. To my mind it is nothing but a female 

 of a form of boisduvalii closely allied to 6. jKipagaija. the black markings of the 

 hindwings being reduced still more. This is the reason I have used this name 

 for the species.] 



Castnia (Athis) orestes Walk. 



Castnia orestes Walker, List Lepid. Ins. Brit. Mus. part i. p. 26 (1854) (Brazil). 



The Tring Museum possesses 1 6 specimens of this species : 

 2 <?<?, 1 ? Petropolis ; 4 cJ(J, 2 ?? Nova Friburgo ; 2 <?<?, 1 ? ? (ex coll. 

 Felder) ; o 33 Brazil ; 1 <J ?.
