GENERIC NAMES OF BUTTERFLIES 161 



ENOSIS Mabille, 1889, Bull. Soc. ent. Fr. 1889 : ix. Type-species by selection by Watson 

 (1893, Proc. zool. Soc. Lond. 1893 : 130) : Enosis dognini Mabille, 1889, ibid. 1889 : ix. 



ENTHEUS Hubner, [1819], Verz. bekannt. Schmett. (8) : 114. Type-species by monotypy : 

 Papilio peleus Linnaeus, 1763, Amoen. acad. 6 : 409). 



The taxon represented by the nominal species Papilio peleus Linnaeus is currently treated 

 subjectively on taxonomic grounds as being the same as that represented by the older-estab- 

 lished nominal species Papilio priassus Linnaeus, 1758, (Syst. Nat. (ed. 10) 1 : 487). 



EOGENES Mabille, 1909, in Seitz, Grossschmett. Erde 1 : 349. Type-species by monotypy : 

 Hesperia alcides Herrich-Schaeffer, (1852), Syst. Bearb. Schmett. Europ. 6 : 38. 



The figures of Hesperia alcides were not published until (1854) (loc. cit. 1 : pi. Hesp. 7, 

 figs 41, 42). 



EOLIMENIT1S Kurentsov, 1950, Byull. mask. Obshch. Isp. Prir. (Ser. biol) 55 (No. 3) : 37-45. 

 Type-species by monotypy : Limenitis eximia Moltrecht, 1909, Ent. Z. 22 : 184. 



EOOXYLIDES Doherty, Dec. 1889, J. asiat. Soc. Bengal, I't II, 58 (4) : 410 et nota. Type- 

 species by monotypy : Oxylides tharis Geyer, [1837], in Hubner, Zutv. z. Samml. exot. 

 Schmett. 5 : 22, pl. [152], figs 883, 884. 



Doherty explained that he had intended to establish for the above species a new genus 

 under the name Marshallia, that when he discovered thai there was already such a 

 name [Marshallia Zittel, 1878], he had decided to establish the same genus under the name 

 Indoxylulcs, and that at this stage he hail informed de Niceville of what he proposed to do. 

 Doherty went on to say that his communication must have reached de Niceville too late for 

 inclusion in his key of the Lycaenidae, in which instead de Niceville had introduced another 

 new name, Eooxylides. On this latter point Doherty must have relied on information, for, as 

 shown below, Eooxylides de Niceville was not published until February 1890, whereas Eooxy- 

 lides Doherty appeared in December 1889. 



EOOXYLIDES de Niceville, February 1890, Butts India Burmah Ceylon 3 : 19, 432. Type- 

 species by original designation : Oxylides tharis Geyer, [1837]. 



This name is invalid, both as a junior homonym of, and as a junior objective synonym of, 

 Eooxylides Doherty, December, 1889. Further particulars will be found in the note on the 

 last-mentioned name. 



EPAMERA Druce, 1891, Ann. Mag. nat. Hist. (6) 8 : 141. Type-species by original desig- 

 nation : Iolaus sidus Trimen, 1864, Trans, ent. Soc. Lond. (3) 2 : 176. 



EPARGYRES Hubner, [1825], Samml. exot. Schmett. 2 : pl. [146] (an Incorrect Subsequent 

 Spelling of Epargyreus Hubner, [1819]). 



EPARGYREUS Hubner, [1819], Verz. bekannt. Schmett. (7) : 105. Type-species by selection 

 by Scudder (1872, 4th Ann. Rep. Peabody Acad. Sci. 1871 : 70) : Papilio tityrus Fabricius, 

 1775, Syst. Ent. : 532. 



When establishing the genus Epargyreus, Hubner did not recognize Papilio tityrus Fabricius 

 as the name of a taxonomically good species, but he did cite that name in the synonymy of one 

 of the species (Papilio clams Cramer, [1775]) which he did so recognize. Accordingly, under 

 the revised Code (Article 69(a) (i)) Papilio tityrus ranks as one of the originally included species 

 of the genus Epargyreus, and Scudder's selection of that species in 1872 to be the type-species 

 was perfectly valid. 



The name Papilio tityrus Fabricius is invalid, as it is a junior homonym of the older name 

 Papilio tityrus Poda, 1761 (Ins. Mus. graec. : 77). The taxon represented by the nominal 

 species Papilio tityrus Fabricius is currently treated subjectively on taxonomic grounds as the 

 same as that represented by the nominal species Papilio clarus Cramer, [1775] (Uitl. Kapellen 

 1 (4) : 66, pl. 41, figs E, F). Under the Commission's Opinion 516 (1958, Opin. int. Comm. 

 zool. Nom. 19 : 1-44) names published by Fabricius in 1775 take precedence, other things 

 being equal, over names published by Cramer in the same year. In the present case however 

 the specific name tityrus Fabricius is, as already explained, invalid under the Law of Homo-
