own. That name, as used by Hiibner, is accordingly here attributed to him and not to Dono- 

 van and is treated as a junior subjective synonym of, as well as a junior homonym of, Papilio 

 evagoras Donovan.

The name Jasia Swainson is invalid, as it is a junior objective synonym of Charaxes Ochsen- 

 heimer, 1816. By the ruling given in Opinion 577 (1959, Bull. zool. Nom. 17 : 140) the 

 Commission placed the name Jasia Swainson on the Official Index of Rejected and Invalid 

 Generic Names in Zoology as Name No. 1306. 



JASONIADES Hiibner, [1819], Verz. bekannt. Schmett. (6) : 83 .Type-species by selection by 

 Scudder (1875) (Proc. amer. Acad. Arts Sci., Boston 10 : 199) : Papilio turnus Linnaeus, 

 1771, Mantissa Plant. 2 : 536. 



The taxon represented by the nominal species Papilio turnus Linnaeus is currently treated 

 subjectively on taxonomic grounds as a form of the taxon represented by the nominal species 

 Papilio glaucus Linnaeus, 1758. The latter, as has already been explained, is the type-species 

 of the genus Euphoeades Hiibner, [1819]. The names Jasoniades and Euphoeades are thus 

 subjective synonyms of one another published in the same work and on the same date. The 

 relative precedence to be accorded to these names depends therefore on the choice made by 

 the First Reviser who was myself when (as explained in the note on Euphoeades) I accorded 

 precedence to the name below Jasoniades Hiibner, of which by that choice Euphoeades 

 became a junior subjective synonym.

JEMADIA Watson, 1893, Proc. zool. Soc. Lond. 1893 : 11, 14. Type-species by selection by 

 Sharp, [1894] in Zool. Rec. 30 (year 1893) (Ins). : 239 : Pyrrhopyga [sic] hospita Butler, 

 1877, Ann. Mag. nat. Hist. (4) 20 : 128. 



The present is one of the very few cases in which Watson fell into error through faulty 

 editing of his paper. What happened was that in his generic key on page 1 1 he designated 

 Pyrrhopyga [sic] patrobas Hewitson, [1857] (III. exot. Butts 2 : [117], p . [59], fig. 1) as type- 

 species of Jemadia, but three pages later (: 14) he designated Pyrrhopyga [sic] hospita Butler, 

 1877 (Ann. Mag. nat. Hist. (4) 20 : 128). It may be assumed that at some stage he changed his 

 mind as to the species to be designated as the type-species, but there is no evidence to show 

 which of the foregoing names was the one that represented his final choice and which therefore 

 remained in the paper as type-species by inadvertence. What is certain however is that for 

 the above reason Watson failed to make a nomenclatorially effective type-selection. This 

 deficiency was made good (probably inadvertently also) by Sharp in his capacity of editor 

 of the Insecta Section of the Zoological Record, when he unambiguously stated that Pyrrhopyga 

 hospita was the type-species. This arrangement has been correctly followed by later authors. 

 (The nominal species Pyrrhopyga patrobas is currently treated subjectively as belonging to 

 a different genus, Elbella Evans, 1951).
