GENERIC NAMES OF BUTTERFLIES 33 



AGRIAS Boisduval, 1870, Consid. Lipid. Guatemala : 52. Type-species by monotypy : 

 Agrias aedon Hewitson, 1848, Proc. zool. Soc. Lond. Pt 16 (182) : 46, pi. 1, 2 figs. 



This is one of a considerable number of cases where Boisduval introduced as a new name of 

 his own a name already published by some other author. That this should have occurred is to 

 be explained by the fact that Boisduval frequently distributed names in manuscript, either in 

 correspondence or attached to the labels of specimens, and was then very slow in publishing 

 those names — so slow, indeed, that, when ultimately he did publish such a name, he had 

 often been anticipated by some author who was aware that the name in question had been 

 proposed by Boisduval. Whatever course such an author might take, he was in a delicate 

 situation : if he himself published the manuscript name, that name so published took prece- 

 dence over the same name when ultimately published by Boisduval, while, if he introduced 

 some entirely new name for the genus, his action invalidated as a junior synonym the manu- 

 script name when later it was published by Boisduval. 



The name Agrias Boisduval, 1870, is invalid as a junior homonym of Agrias Doubleday, 

 1844. 



AGRODIAETUS Hiibner, 1822, Syst. alph. Vers. : 1-10. Type-species by selection by 

 Hemming (1934, Gen. Names hoi. Butts 1 : 109) : Papilio damon [Denis & Schiffermiiller], 



1775, Ankiindung [sic] eines syst. Werkes Schmett. Wiener Gegend : 182. 



Iltibner used the word " Agrodiaetus " as a descriptive term applied to various species in 

 the Zutrdge but he never there coupled this word with a specific name as a generic name. In 

 the Verzeichniss he used this word in the plural (as " Agrodiaeti ") but he never employed 

 it as a generic name. As shown above, he did however so employ it in 1822 in the Syst. 

 alph. Verz., where he treated it as the generic name for all the European species of the family 

 Lycaenidae known to him. Three years later (1825, Cat. Lep. Coll. Franck : 82) he again 

 used the word " Agrodiaetus " in a strictly generic sense. In 1875 (Proc. amer. Acad. Arts 

 Sci., Boston 10 : 106) Scudder selected Papilio damon [Denis & Schilfermiiller] as the type- 

 species of Agrodiaetus but unfortunately he related that selection to that name as used by Hiib- 

 ner in 1825 in the Franck Catalogue. The prior use of the name Agrodiaetus by Hiibner in 

 1822 in the Syst. -alph. Verz. remained unnoticed until attention was drawn to it by myself in 

 1934 (: 109). As noted above, I then selected Papilio damon as the type-species, thus 

 validating the practice which had grown up in the period since the selection of that species 

 by Scudder on the incorrect assumption that it was in the Franck Catalogue that the name 

 Agrodiaetus was first published. 



AGRUSIA Moore, [1894], Lep. ind. 2 (18) : 144 ; 2 ibid. (19) : 169. Type-species by original 

 designation : Melanitis esaca Westwood, [1851], in Doubleday, Gen. diurn. Lep. (2) : 405, nota. 



AGUNA Williams, 1927, Trans, amer. ent. Soc. 53 (3) : 286. Type-species by original 

 designation : Eudamus camagura Williams, 1926, Trans, amer. ent. Soc. 52 : 81. 



AHLBERGIA Bryk, 1946, Arkiv Zool. 38A (No. 3) : 50. Type-species through Section (i) 

 (replacement names) of Article 67 : Lycaena ferrea Butler, [1866], /. linn. Soc. Lond., Zool. 



9:57- 



As a replacement genus, Ahlbergia automatically takes as its type-species the nominal 

 species which is the type-species of the genus replaced (Satsuma Murray), namely Lycaena 

 ferrea Butler. Bryk, not realizing that for the above reason Lycaena ferrea must be the 

 type-species of this substitute genus, designated Thecla frivaldszkyi Lederer, 1855 (Verh. 

 zool.-bot. Ver. Wien 5 : 100, pi. 1, fig. 1 $) erroneously as type-species. He took this action 

 because he considered that the taxon represented by Lycaena ferrea was a subspecies of the 

 taxon represented by the nominal species Thecla frivaldszkyi. 



The name Ahlbergia is invalid, because, as a substitute name, it was anticipated by the name 

 Ginzia Okano, 1941.
