178 FRANCIS HEMMING 



( : 19) the generic name Eumesia on the ground that the holotype of its type-species (Eumesia 

 semiargentea) now in the British Museum was a specimen which had lost its head and on which 

 in place of the missing head the head of some Satyrid species had been gummed. Evans's 

 ground for rejecting this generic name was that the substitution of this false head on the holo- 

 type vitiated the generic diagnosis given by the authors of this name. This action was mis- 

 conceived, there being nothing in the Code to authorize the rejection of a generic name on 

 such grounds. Moreover, Evans's contention was incorrect in fact, for only part of the original 

 diagnosis was concerned with the characters of the head. Quite apart from this consideration, 

 Evans forgot that prior to 1931 it was not necessary for an author to provide any diagnosis for 

 a new genus, provided that he included in the genus one or more duly established nominal 

 species. This condition was duly complied with by the authors of this generic name. The 

 name Eumesia is therefore an available name, and accordingly Evans's action in rejecting it 

 was invalid. 



EUNICA Hiibner, [1819], Verz. bekannt. Schmett. (4) : 61. Type-species by selection by Scudder 

 (1875), Proc. amer. Acad. Arts Set., Boston, 10 : 171) : Papilio monima Stoll, [1782], in 

 Cramer, Uitl. Kapellen 4 (33) : 202, pi. 387, figs F, G. 



Thetaxon represented by the nominal species Papilio monima is currently treated subjective- 

 ly on taxonomic grounds as being congeneric with that represented by the nominal species 

 Papilio amelia Cramer, [1777], the type-species of the genus Evonyme Hiibner, [1819]. The 

 names Eunica and Evonyme were published on the same page of the Verzeichniss and the 

 relative precedence to be accorded to them depends therefore on the choice of the First 

 Reviser. This was Kirby (187 1, Syn. Cat. Dhtrn. Lep. : 198) who adopted the name Eunica, 

 sinking Evonyme as a junior synonym. 



EUNICE Geyer, [1832], in Hiibner, Zutr. z. Sam ml. exot. Schmett. 4 : 39. Type-species by 

 selection by Hemming (1939, Proc. R. ent. Soc. Lond. (B) 8 : 134) : Eunice taurione Geyer, 

 [1832], in Hiibner, ibid. 4 : 39, pi. [135], figs 783, 784. 



The taxon represented by the nominal species Eunice taurione is currently considered sub- 

 jectively on taxonomic grounds to be congeneric with that represented by the nominal species 

 Papilio monima Stoll, the type-species of Eunica Hiibner, [1819]. The position as regards this 

 pair of generic names is thus exactly similar to that of Eumaea Geyer and Eumaeus Hiibner 

 which has been fully discussed in the note on the name Eumaea Geyer. For the reasons there 

 explained, the name Eunice may have been an intentional emendation by Geyer of the name 

 Eunica Hiibner; it may also be no more than an inadvertent Incorrect Subsequent Spelling 

 of Hiibner's Eunica. There is however no evidence provided by Geyer which would bring the 

 name Eunice within the definition laid down in the Code either for an Emendation or for an 

 Incorrect Subsequent Spelling. The name Eunice must therefore be treated nomenclatorially 

 as a new name introduced by Geyer intentionally. 



From a practical point of view the exact status to be accorded to the name Eunice Geyer 

 is of academic interest only, for in any circumstances the name Eunice Geyer would be invalid 

 under the Law of Homonymy, the word " Eunice " having been used as a generic name by 

 two authors before it was so used by Geyer. The names in question are : (i) Eunice Rafines- 

 que, 1816 {Analyse Nature : 135); (ii) Eunice Schinz, 1822 (in Cuvier, Thierreich 2 : 310).

 1851], in Doubleday, ibid. (2) : pi. 72, fig. n. 



The text relating to this name ( : 463) was published a little later (in December 185 1), and in 

 it also Westwood placed only the nominal species Eunogyra satyrus in the genus Eunogyra.

 Type-species through Section (i) (replacement names) of Article 67 : Papilio crithea Drury, 

 [1773], III. nat. Hist. 2 : index et 29, pi. 16, figs 5, 6. 



The name Euomma was introduced as a replacement for Jaera Hiibner, [1819], which is 

 invalid under the Law of Homonymy.
