GENERIC NAMES OF BUTTERFLIES 165 



This is another case in which BoisduvaJ put a manuscript name into irregular circulation 

 and owing to his dilatoriness was anticipated in publishing it by another author (in this case 

 Doubleday). When at last Boisduval did publish this name (in 1870), he attributed it to 

 himself and treated it as a new name. 



The name Epiphile Boisduval is invalid, as being a junior homonym of Epiphile Doubleday, 

 1844.

EPITHOMIA Godman & Salvin, [ 1879], Biol, centr. -amer., Lep. Rhop. 1 : 32. Type-species by 

 original designation : Dircenna callipero Bates, 1863, Proc. zool. Soc. Lond. 1863 : 243, pi.

EPITOLA Westwood, [1851], in Doubleday, Gen. diurn. Lep. (2) : pi. 68, fig. 5. Type-species 

 by monotypy : Epitola elion Westwood, [1851], in Doubleday, ibid. (2) : pi. 68, fig. 5; id., 

 [1852], ibid. (2) : 471. 



In the text (: 471) published in 1852 as well as on plate 68 published in the previous year 

 Westwood placed in this genus only the single species Epitola elion, which would therefore 

 have been the type-species by monotypy even if the text had been published at the same time 

 as plate 68.

EPITYCHES Ferreira d'Almeida, 1938, Brasil-med. Rio de Janeiro 52 : 412. Type-species 

 by original designation : Tritonia eupompe Geyer, [1832], in Hiibner, Zutr. z. Samml. 

 exot. Schmett. 4 : 25, pi. [121], figs 699, 700. 



The name Epityches is a junior objective synonym of Tritonia Geyer, [1832], but it is never- 

 theless an available name, because Tritonia Geyer is itself invalid under the Law of Homo- 

 nymy.

 Type-species through Section (i) of Article 67 : Epeus veleda Godman, [Feb. 1901], in 

 Godman & Salvin, ibid., Lep. Rhop. 3 : 601, pi. 103, figs 21, 22, 23 <J. 



Godman introduced the name Eprins as a replacement for Epeus Godman, published earlier 

 in the same year, which is invalid under the Law of Homonymy. 



EQUES Kirby, 1896, in Allen's Nat. Libr., Lepid. 1, Butts 2 : 290. Type-species by original 

 designation : Papilio nireus Linnaeus, 1758, Syst. Nat. (ed. 10) 1 : 464. 



Eques is one of the terms used by Linnaeus for subdivisions of his genus Papilio which for a 

 long time caused confusion in nomenclature owing to disagreement among systematists as to 

 whether these terms should be regarded as of subgeneric status as from Linnaeus. It was not 

 until 1936 (Smithson. miscell. Coll. 73 (No. 8) : 1-2 ; republished in facsimile in 1958, 

 Opin. int. Comm. zool. Nom. 1 (B) : 465-466) that doubts on this subject were finally 

 dispelled, the Commission in that year promulgating its Opinion 124, in which it ruled that 

 these intermediate terms possessed no status in nomenclature. 



Kirby (1896) was the first author to use the term Eques as a generic name in a strictly bi- 

 nominal sense, and it must therefore be attributed to him. Eques Kirby is invalid under the 

 Law of Homonymy, being a junior homonym of Eques Bloch, 1793 (Nat. ausl. Fische 7 : 90).
