GENERIC NAMES OF BUTTERFLIES 27 



D, E, F, G. 



The drawings of the larva and pupa of what in the legend of pi. 3 Boisduval called Adolias 

 aconthea were copied by him from the figures given by Horsfield in [1829] (Descr. Cat. lep. 

 Ins. Mus. East India Coy (2) : explic. pi. 8, fig. 6) for his then new nominal species Aconthea 

 primaria. It will be recalled from the discussion on the nominal genus Aconthea Horsfield, 

 [1829], of which the foregoing nominal species is the type-species, that it seems likely that 

 1 lorsfield looked upon Aconthea primaria as a substitute nominal taxon for the older-establish- 

 ed nominal species Papilio aconthea Cramer but he gave no clear evidence that this was his 

 view. On the present occasion however Boisduval by reproducing Horsfield's figures under 

 the name Adolias aconthea definitely established a subjective synonymy between the nominal 

 species Papilio aconthea Cramer and Aconthea primaria Horsfield. The nominal genera 

 Adolias Boisduval, [1836], and Aconthea Horsfield, [1829], thus have as their respective 

 type-species nominal species which are currently considered on taxonomic grounds to represent 

 the same taxon. As this synonymization rests only on a subjective basis, the later-published 

 of these names, that is, Adolias Boisduval, remains a nomenclatorially available name.

 quent Spelling of Adopoea Billberg, 1820). 



ADOPAEOIDES Godman, [1900], in Godman & Salvin, Biol. cent. -amer., Lep.-Khop. 2 : 470. 

 Type-species through Section (a) (misidentified type-species) of Article 70 provisionally 

 applied, pending a decision by the Commission on an application submitted : Apaustus 

 prittwitzi Plotz, 1884, Stett. enl. Ztg 45 : 165. 



Godman designated Ancyloxypha simplex Felder (R .), 1869 (Verh. zool.-bot. Ges. Wien 

 19 : 476) as the type-species of this genus. There is however clear evidence that he misidenti- 

 fied the nominal species Ancyloxypha simplex Felder and that the species to which he incor- 

 rectly supposed that name to apply was, in fact, Apaustus prittwitzi Pldtz. First, Godman 

 gave four figures {$ ups. ; o" unds. ; venation, o" genit.) (figs 30-33 on pi. 92) of what he then 

 identified as Ancyloxypha simplex ; all of these are referable to Apaustus prittwitzi. Second, 

 Godman gave (: 471) a description of his " simplex Felder " ; this applies to Apaustus 

 prittwitzi but not to the true Ancyloxypha simplex of Felder. Third, he gave (: 470) a diagno- 

 sis of the genus Adopaeoides which agrees with the characters shown by Apaustus prittwitzi 

 but not with those of Ancyloxypha simplex. 



In the most recent treatment of this group (1955, Cat. Amer. Hesp. Brit. Mus. 4 : 309) 

 Evans, after summarizing the evidence set out above, treated Apaustus prittwitzi as the type- 

 species of this genus, at the same time identifying the true Ancyloxypha simplex Felder with 

 the older-established nominal species Ancyloxypha aurantiaca Hewitson, 1868 (Descr. One 

 Hundred new Spec. Hesp. (2) : 45). With this latter also there is identified the later-estab- 

 lished nominal species Heteropterus procris Edwards, 1871 (Trans, amer. ent. Soc. 3 : 215), the 

 type-species of the genus Copaeodes Speyer, 1877 [in Edwards, Trans, amer. ent. Soc. 6 : 49, 

 64). Thus on the basis of the subjective synonymy set out above the generic name Adopae- 

 oides Godman would disappear as a junior subjective synonym of Copaeodes Speyer, if the true 

 Ancyloxypha simplex Felder (the nominal species designated by Godman) and not the species 

 Apaustus prittwitzi Plotz (the species misidentified with Ancyloxypha simplex by Godman, 

 were accepted as the type-species of Adopaeoides. In that event the species Apaustus pritt- 

 witzi would lose the name Adopaeoides currently applied to it and would in future have to be 

 known by the name Neadopaea Hayward, 1941, a name introduced against this contingency 

 which however has not received a favourable reception. 



An application has been made to the Commission to use its Plenary Powers to secure that in 

 harmony with Article 70(a) of the Code the nominal species to be accepted as the type-species 

 of Adopaeoides Godman shall be Apaustus prittwitzi Plotz, the species intended by Godman 

 when he erroneously used the name Ancyloxypha simplex Felder. In the interests of nomen- 

 clatorial stability the name Adopaeoides is here provisionally treated, in anticipation of a 

 ruling by the Commission, as though a ruling in the foregoing sense had already been given.
