year. It may be concluded that the Trans, was the earlier, because in the Illustr. Hewitson 

 gave a bibliographical reference to the Trans. 



ARESTA Billberg, 1820, Enum. Ins. Mus. Billb. : 79. Type-species by selection by Scudder 

 (1875, Proc. amer. Acad. Arts Sci., Boston 10 : 117) : Papilio laomedia Linnaeus, 1767, 

 Syst. Nat. (ed. 12) 1 (2) : 772. 



The taxon represented by the nominal species Papilio laomedia Linnaeus is currently 

 treated subjectively on taxonomic grounds as representing the same taxon as that represented 

 by the older-established nominal species Papilio atlites Linnaeus, 1763 (Amoen. acad. 6 : 407). 



ARETHUSANA de Lesse, 1951, Rev. franc. Lipid. 13 (3/4) : 40. Type-species by original 

 designation : Papilio arethusa [Denis & Schiffermuller], 1775, Ankiindung syst. Werkes 

 Schmett. Wiener Gegend : 169, no. F. 16. 



This species, when designated as the type-species of Arethusana, was attributed by de Lesse 

 to Esper (i.e. Papilio arethusa Esper, [1781], Die Schmett. 1 (Bd 2) Forts. Tagschmett. : 103, 

 pi 69, fig 3 o\ 4 $). but Esper did not publish this as a new name of his own, correctly 

 attributing it to Denis & Schiffermuller. Until recently there was some doubt as to the 

 availability of the specific name arethusa for the present species, owing to the possibility that 

 it might be a junior homonym of the specific name arethusa Cramer, [1775], also published in 

 the combination Papilio arethusa. Luckily, this question was settled by the Commission in 

 J 958 (Opin. int. Comm. zool. Nom. 19 : 1-44) when by its Ruling given in Opinion 516 it 

 determined the relative precedence to be accorded to certain works on the Lepidoptera 

 published in 1775 ; for it then ruled that the names introduced in Denis & Schiffermuller's 

 work were to be accorded precedence over those introduced in that year in Cramer's work. 

 Under this Ruling the specific name arethusa [Denis & Schiffermuller], 1775, as published in the 

 combination Papilio arethusa, became without question the oldest available specific name for 

 the present species. 



ARGE Hiibner, [1819], Verz. bekannt. Schmett. (4) : 60. Type-species by selection by Butler 

 (1868, Ent. mon. Mag. 4 : 196) : Papilio psyche Htibner, [1799-1800], Samml. europ. Schmett. : 

 pi. Pap. 44, figs 198, 199. 



The reference given above for the type-species is that furnished by Hiibner himself in the 

 Verzeichniss ; he had, however, previous to the publication of plate Pap. 44 of the Sammlung, 

 published the same name for this species in an earlier work, [1 790-1793] (Der Schmett. Lepid. 

 linn. : 9). 



The name Arge Hiibner is invalid, as it is a junior homonym of the name Arge Schrank, 

 1802 {Fauna boic. 2 (2) : 209). 



By the Ruling given in its Opinion 400 (1956, Opin. int. Comm. zool. Nom. 12 : 419- 

 432) this name was placed by the Commission on the Official Index of Rejected and Invalid 

 Generic Names in Zoology as Name No. 416.
