GENERIC NAMES OF BUTTERFLIES 167 



ERESINA Auriviilius, 1898, K. svenska VetenskAkad. Hand!., Stockholm 31 (No. 5) : 253, 282. 

 Type-species by original designation : Durbania corynetes Grose-Smith & Kirby, 1890, 

 Rhopal. exot. 1 (14) : 57, pi. 11, figs 7, 8 <J. 



The generic name of the type-species was printed in the old-fashioned and now incorrect 

 form " D'Urbania ".

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

 pi. 4 [= pi. 4A], fig. 4 (larva et pupa). Type-species by monotypy : Papilio ariadne

ERIBOEA Hiibner, [1819], Verz. bekannt. Schtnett. (3) : 46. Type-species by selection by 

 Scudder (1875, Proc. amer. Acad. Arts Sci., Boston 10 : 166) : Papilio etheocles Cramer, 

 [1777], Uitl. Kapellen 2 (10) : 34, pi. 119, figs D, E. 



Under the present Code (Article 69(a) (i)) Papilio etheocles Cramer ranks as one of the 

 originally included species of Eriboea, for, although Hiibner did not include it among what he 

 regarded as taxonomically good species, he did however so include the nominal species Eriboea 

 etheoclessa then introduced ( : 47) as a replacement for Papilio etheocles. 



The correct interpretation of the present nominal genus is now well understood — see Hem- 

 ming, 1934 (Gen. Names hoi. Butts 1 : 95) — but in view of the former widespread misuse of 

 this name, a brief note is required. From the taxonomic point of view it must be noted that 

 two fairly closely allied genera of Charuxid Nymphalids are involved. These are: — ■ (a) 

 Charaxes Ochsenheimer, 1816; (b) the Oriental genus typified by the nominal species Papilio 

 athamas Drury, [1773]. First, it must be noted that Papilio etheocles Cramer, the type-species 

 of Eriboea, is currently referred to the genus Charaxes ; on the basis of this subjective taxonomic 

 view the name Eriboea Hiibner is treated as a junior subjective synonym of Charaxes Ochsen- 

 heimer. The second of the genera referred to above was erroneously referred by Scudder 

 (1875, Proc. amer. Acad. Arts Sci., Boston 10 : 170) and later by Moore ([1880], Lep. Ceylon 1 

 : 29) to the Riodinid genus Eulepis Billberg, 1820. This mistake arose from the fact that, in 

 establishing the Riodinid genus, Billberg included a manuscript species to which he applied the 

 name athamas which Scudder misinterpreted as being the Nymphalid Papilio athamas Drury. 

 Rober in [1909] (in Seitz, Grossschmett. Erde 1 : 169, nota) realized that this use of the name 

 Eulepis Billberg was incorrect and that some other name must be found for the genus con- 

 taining Papilio athamas Drury. Unfortunately, Rober picked out for this purpose the name 

 Eriboea Hiibner, seeking to justify this choice by advancing an argument — actually, entirely 

 fallaceous — that Papilio athamas Drury was the type-species of that genus. Now that Rober's 

 action has been accepted as having been misconceived, the name Polyura Billberg, 1820 (type- 

 species: Papilio pyrrhus Linnaeus, 1758) has been correctly brought into use for the genus 

 here in question.

ERIDAMUS Burmeister, 1875, Rev. Mag. Zool. (3) 3 : 51-59. Type-species by selection by 

 Evans (1952, Cat. amer. Hesp. Brit. Mus. 2 : 44) : Goniuris tmolis Burmeister, 1875, ibid. 

 (3) 3 : 64, pi. 1, figs 1 (larva), 8, 9 (portions of larva). 



Burmeister's paper is exceptionally obscure and badly constructed, and it is not surprising 

 therefore that the generic name Eridamns has been almost completely overlooked by later 

 authors. Burmeister included two nominal species in this genus, but neither was selected as 

 the type-species until the publication of Evans' book in 1952. Evans erroneously believed
