GENERIC NAMES OF BUTTERFLIES 173 



entry " Eucora ", an entry which reads " Eucorma = Eucora ". It is true that this rather 

 cryptic entry could have been intended to denote that the spelling Eucorma was a misspelling 

 of the name Eucora, but it seems more likely that it was intended to draw attention to the 

 deliberate introduction of the spelling " Eucorma " in replacement of the spelling " Eucora ". 

 Fortunately, it is not necessary to pursue further the question as to whether the spelling was 

 introduced deliberately or not; for, even if it were agreed that the spelling " Eucorma " was 

 intentional, the name so spelled would have been invalid, as it would have been a junior 

 homonym of the name Eucorma Jordan, 1908] (in Seitz, Grossscliwelt. Erde 10 : 30). 



EUCORNA Strand, 1032, Folia zool. hydrobiol., Riga 4 (1) : 146. Type-species through 

 Section (i) (replacement names) of Article 27 : Eucora sanarita Schaus, 1902. 



The name Eucorna Strand was introduced as a replacement for the name Eucora Schaus, 

 1902, which is invalid under the l..iw "I Homonymy. 



EU DAEMON Billberg, 1820, Enum. Ins. Mus. Billb. : 76. Type-species by selection by 

 Hemming (1934, Gen. Names hoi. Hulls 1 : 26) : Papilio claudia Fabricius, 1777, Gen. Ins. : 

 263. 



When I dealt with this matter in 1934 (: 26), I took the view that, as Moore (1883, Proc. 

 zool. Soc. Loud. 1883 : 286) had treated Eudaemon Billberg as a junior synonym of the name 

 Trepsichrois when he selected Papilio claudia Fabrii ins as the type-species of Trepsictirois, he 

 could properly be treated as having at the same time selected that species to be the type-species 

 of Eudaemon also. I now consider however that that argument was fallacious, but the above 

 species is undoubtedly the type-species of this genus, it having been unequivocally specified 

 as such by myself in 1934. 



The name Papilio claudia Fabricius, as applied to the present species, is invalid, as it is a 

 junior homonym of the older name Papilio claudia Cramer, [1775] (I 'ill. Kapellen 1 (6) : 109). 

 The oldest name that is both available under the Code and subjectively applicable to the 

 present species is mulciber Cramer, [1777 Papilio mulciber Cramer, 1777' [Uitl. Kapellen 2 

 (n) : 45, pi. 127, figs C, I)). 



EUDAMIDAS C.odman & Salvin, [1895], Biol, centr.-amer., Lep, Rhop. 2 : 386. Type-spei ies 

 by selection by Lindsey (1925, Ann. ent. Sot Inter. 18 : 86) : Papilio melander Cramer, 

 [1780], Uitl. Kapellen 3 (23) : 141, pi. 270, fig. II. 

 The taxon represented by Papilio melander Cramer 1-- currently treated subjectively on 



taxonomic grounds as being the same as that represented by the older-established nominal 

 species Papilio menippus Fabricius, 1770 ((ieu. Ins. : 272). 



EUDAMUS Swainson, 1831, Zool. Illustr. (1) 2 : pi. 48. Type species by original designation : 

 Papilio proteus Linnaeus, 1758, Syst. N«l. (ed. 10) 1 : 484. 



The name Eudamus Swainson is invalid, as it is a junior objective synonym of Urbanus 

 Hiibner, [1807]. 



EUDAPHNE Reuss, 1922, Archiv. Naturgesch. 87 (1921) A. 11 : 221. Type-species by original 

 designation : Papilio laodice Pallas, 1771, Reise durrh Verschied.prov. Russisch. Reichsl : 470. 

 The name Eudaphne Reuss is invalid, as it is a junior obje< tive synonym of Argyronome 

 Hiibner, [1819]. 



EUDRYAS Reuss, 1926, Int. ent. Z. 20 : 253. Type-species by original designation : Argynnis 

 childreni Gray, 1831, Zool. Miscell. (Gray) (1) : 33. 



Early in the following year (Jan. 1927, Dtsch. ent. Z. 1926 (5) : 435) Reuss again published 

 Eudryas as a new name, once more designating the above species as type-species. 



The name Eudryas Reuss is invalid under the Law of Homonymy, the same word having 

 been used as a generic name by four different authors. The names concerned are: — (i) 

 Eudryas Boisduval, [1836] (Roret's Suite a Button), Hist. nat. Ins., Consid. gen. 1 (Lepid.) : 

 pi. 14 [= pi. 10 B], fig. 9; (ii) Eudryas Harris, 1841, Ins. Massachusetts : 310; (iii) Eudryas 

 Fitzinger, 1843, Systs. Rept. : 26; (iv) Eudryas Gistl, 1848, Nat. Thierr. : viii. 



The name Eudryas Reuss has been replaced by the name Childrena Hemming, 1943.
