GENERIC NAMES OF BUTTERFLIES 169 



name Eropits had been drawn they had ascertained that the generic name had already been 

 published as the name for a different genus. They accordingly thereupon introduced the 

 replacement name Theagenes for the present genus. 



ERORA Scudder, 1872, 4th Ann. Rep. Peabody Acad. Sci. 1871 : 53. Type-species by original 

 designation : Thecla laeta Edwards, 1862, Proc. Acad. nat. Sci. Philad. 1862 : 55. 



EROTION Billberg, 1820, Ennm. Ins. Mus. Billb. 80. Type-species by monotypy : Papilio 

 cupidu Linnaeus, 1758, Syst. Nat. (ed. 10) 1 : 482. 



The name Erolion Billberg is invalid, as it is a junior objective synonym of Helicopis 

 Fabricius, 1807. 



ERSCHOFFIA Tutt, [1907], Nat. Hist. Brit. Butts 2 : 142. Type-species by original desig- 

 nation : Thecla lunulata Erschoff, M&m. Soc. Amis Sci. nat. Moscou 11 (No. 2) : 7, pi. 1, 

 fig. 5 $ — usually cited under the title of Erschoff's paper, there published, as " Fedschenko 

 Rcise Turkestan ". 



The name Erschoffia Tutt is invalid as being a junior homonym of Erschoffia Swinhoe, 1900 

 (Cat. east. Lep. Het. Oxford Univ. Mus. 2 : 221). It has been replaced by the name Pseudo- 

 thecla Strand, kjio. 



ERYCIDES Hiibner, [1819], Verz. bekannt. Schmett. (7) : 110. Type-species by selection by 

 Scudder (1872, 4th Ann. Rep. Peabody Acad. Sci. 1871 : 67) : Papilio pigmalion Cramer, 

 [1779], Uitl. Kapellen 3 (21) : 87, pi. 245, figs A, B: 



The type-species of this genus is usually treated subjectively on taxonomic grounds to be 

 congeneric with Papi/i<> palemon Cramer, [1777], the type-species of Phocides Hiibner, [1819] 

 (he. cit. (7) : 103). On this basis the names Erycides and Phocides are subjective synonyms 

 of one another and as they were published in the same work on the same date, the relative 

 precedence to be accorded to them depends on the choice made by the First Reviser. This 

 was Godman & Salvin who in 1893, Biol, cenlr.-amer., Lep. Rhop. 2 : 292 adopted the name 

 Phocides, sinking Erycides as a junior synonym. 



ERYCINA Fabricius, 1807, Mag. f. Insektenk. (Illigcr) 6 : 286. Type-species by selection by 

 Crotch (1872, Cistula ent. 1 : 66) : Papilio lysippus Linnaeus, Syst. Nat. (ed. 10) 1 : 484. 



The name Frycina Fabricius is invalid, as it is a junior homonym of Erycina Lamarck, 

 1805 (Ann. Mus. Hist, nat., Paris 6 (36) : 413). 



The type-species of the present genus is also the type-species of the later-established genus 

 Riodina Westwood, [1851], in which it is now placed. 



ERYCINIDIA Rothschild & Jordan, 1905, Novit. zool. 12 : 457. Type-species by monotypy : 

 Erycinidia gracilis Rothschild & Jordan, 1905, ibid. 12 : 457. 



ERYNNIS Schrank, 1801, Fauna boic. 2 (1) : 152, 157. Type-species by selection by Scudder 

 (1872, 4/A Ann. Rep. Peabody Acad. Sci. 1871 171): Papilio tages Linnaeus, 1758, Syst. Nat. 

 (ed. 10) 1 : 485. 



ERYPHANE Boisduval, 1870, Consid. Lepid. Guatemala : 58 (an Incorrect Original Spelling of 

 Eryphanis Boisduval, 1870). 



ERYPHANIS Boisduval, 1870, Consid. Lipid. Guatemala : 57. Type-species by original 

 designation : Papilio automedon Cramer, [1775], Uitl. Kapellen 1 (4) : 65, pi. 41, figs A, B. 

 When establishing this genus ( : 57) Boisduval used the spelling " Eryphanis " and it cannot 

 reasonably be doubted that this was the spelling which he wanted to employ. However, on 

 the following page ( : 58) two other spellings were used by what appears to have been due to 

 inadvertence or more probably bad type-setting and bad proof-reading. The spellings in 

 question were " Euryphanis " and " Eryphane " . Under the Code all three of these spellings 

 rank as Original Spellings and the question of the one to be accepted as the Correct Original 

 Spelling depends on the choice of the First Reviser. The F~irst Reviser in this case was Scudder 

 who in 1875 (Proc. amer. Acad. Arts Sci., Boston 10 : 168) choose the spelling " Eryphanis " 

 to be the Correct Original Spelling, sinking the spellings " Euryphanis " and " Eryphane " as 

 synonyms.
