GENERIC NAMES OF BUTTERFLIES 99 



Kirby introduced the name Casyapa as a replacement for Chaetocneme Felder (C), 1850, 

 which, following Scuddcr 1875, Proc. amer. Acad. Arts Sci., Boston 10 : 139), he erroneously 

 rejected as a junior homonym of Chaetocnema Stephens, 1831. Under the "One-Letter" 

 Rule now embodied in Article 57(d) these names are not to be looked upon as being homonyms 

 of one another. Accordingly, the name Chaetocneme Felder is an available name, and its 

 replacement name Casyapa Kirby is invalid as a junior objective synonym of Chaetocneme 

 Felder.

 Boisduval, [1836], ibid. 1 : pi. <», tig. 2. 



The taxon represented by Boisduval on ln> plate 9 is currently identified on taxonomic 

 grounds with that represented by the nominal spe< ies Nymphalis pygas Godart, [1824] 

 (Ency. mith. 9 (Ins.) (2) : 423). On his plates Boisduval placed at the foot of each plate the 

 name of each species figured ; sometimes he addled th< 1 the author of the specific name 



concerned, but not always. In the present case he cited no author's name. In the leaflet 

 printed at some unknown but certainly considerably later date with the title " Spe< ies General 

 des Lepidopteres : Explication des Blanches composant Ies deux livraisons qui accompagnent 

 le premier volume " the information given at the foot of plates was supplemented by the 

 following information : — " Catagramma Hydaspes, Fab. (non God.). Bresil ". When I 

 dealt with this matter in 1934 (Gen. Names hoi. Butts 1 : 85) I treated Catagramma as a genus 

 based on a misidentifled type spei ies. 1 aow consider however that, in view of the fact that 

 Boisduval gave no author's name for hydaspes at the foot of the plate, the preferable course 

 would be to treat the name Catagramma hydaspes, as there published, as being a new name 

 of Boisduval 's own, more especially in view of the fact that the information given in the later- 

 published leaflet gives no clear indication of the name, if any, which — according to that 

 leaflet — its author considered was objectively applicable to the taxon figured on plate 9. 

 The procedure here proposed is in harmony with the provision now embodied in Article 70(b) 

 - — which did not exist at the time when this matter was considered by myself in 1934 — under 

 which, when an author deliberately uses for the type-species of a genus an older name in 

 some qualified sense, he is to be treated as having thereby himself established a new nominal 

 species.
