Vellida (hamptsteadiensis). 



1 828. Ilorsf., Descr. Cat. Lep. E. Ind. Co., expl. pi. : cardui only. 



1840. Westw., Gen. Syn. 87 : specifies cardui as type.

lida (hamptsteadiensis). 

 1849. Doubl., Gen. Diurn. Lep. 212: restricts it to Arsinoe only. 



1871. Kirb., Syn. Cat. 152: restricts it to Ai'sinoe and Erota. 



1872. Crotch, Cist. Ent. i. 66: says that cardui is type, through 



Ilorsfield's action in 1828. 



Cardui would be type, but tliat it is strictly congeneric with Ata- 

 lanta which Wcas previously (Latr. 1810) designated as type of Vanessa. 

 Arsinoe must therefore be taken as the type. 



318. Ctkenia. 



1851. "VVestw., Gen. Diurn. Lep. 434: Martia. Sole species, and 

 therefore type. 



Should tills name be dropped as preoccupied ? Cyrene has been

1832. Boisd., Voy. Astrol. 117 : Thyonneus (Thyoneus), Acilia. 



1833. lb., Ann. Mus. Hist. Nat. 190 : elegans. 



It has since been used in the same sense by different authors, as 

 Doubleday, Westwood, etc. 



1861. Feld., Neues Lep. 24: divides the group into two sections, to 

 the first of which he refers Thyonneus, and to the second 

 Risa and Rahria. 

 Thyonneus may then be taken as the type.
