GENERIC NAMES OF BUTTERFLIES 381 



PSELNA Billberg, 1820, Enum. Ins. Mus. Billb. : 77. Type-species through Section (i) 

 (replacement names) of Article 67 : Papilio piera Linnaeus, 1758, Syst. Nat. (ed. 10) 1 : 465. 

 The name Pselna Billberg is invalid as a junior objective synonym of Haetera Fabricius, 

 1807, as a replacement of which it was introduced entirely unnecessarily. 



PSEUDACRAEA Westwood, [Sept. 1850], in Doubleday, Gen. diurn. Lep. (2) : 281. Type- 

 species by selection by Scudder (1875, Proc. amer. Acad. Arts Sci., Boston 10 : 258) : Papilio 

 hirce Drury, [1782], ///. nat. Hist. 3 : index et 37, pi. 28, figs. 3, 4. 



The taxon represented by the nominal species Papilio hirce Drury is currently treated 

 subjectively on taxonomic grounds as being the same as that represented by the older- 

 established nominal species Papilio eurytus Linnaeus, 1758, Syst. Nat. (ed. 10) 1 : 487. 



PSEUDALETIS Druce, 1888, Ent. mon. Mag. 24 : 259. Type-species by original designation: 

 Pseudaletis agrippina Druce, 1888, ibid. 24 : 250 



PSEUDALMENUS Druce, 1902, Proc. zool. Soc. Lond. 1902 (vol. 2) (1) : 116. Type-species 

 by original designation : Ialmenus myrsilus Westwood, [Dec. 185 1], in Doubleday, Gen. 

 diurn. Lep. (2) : pi. 75, fig. 3 [text (ibid. (2) : 487), where treated as a Thecla species, published 

 in April 1852]. 



PSEUDAMATHUSIA Honrath, 1886, CorrespBl. ent. Yer. Iris 1 (3) : 91. Type-species by 

 monotypy : Pseudamathusia ribbei Honrath, 1886, ibid. 1 (3) : 91, pi. 3, fig. 1. 



The taxon represented by the nominal species Pseudamathusia ribbei Honrath is currently 

 treated subjectively on taxonomic grounds as being the same as that represented by the 

 older-established nominal species Amathusia virgata Butler, 1870 (Trans, ent. Soc. Lond. 

 1870 : 486). 



PSEUDANAPHAEIS Bernardi, 1953, Rev. franc. Ent. 20 (1) : 50. Type-species by original 

 designation : Pieris gidica Godart, [1819], Ency. mtth. 9 (Ins.) (1) : 131. 



PSEUDARGYNNIS Karsch, 1892, Ent. Nachr. 18 (11/12) : 173. Type-species by mono- 

 typy : Jaera duodecimpunctata Snellen, 1S72, Tijdsclir. Ent. (2) 7 : 15, pi. 1, figs 1-3. 



The taxon represented by the nominal species Jaera dumlecimpuyxctata Snellen is currently 

 treated subjectively on taxonomic grounds as being the same as that represented by the 

 older-established nominal species Argynnis hegemone Godart, [1819], Ency. mith. 9 (Ins.) 

 (1) : 258. 



PSE UD A THYMA Standi nger, 189 1, Iris 4 (1) : 90. Type-species by monotypy : Pseudacraea 

 sibyllina Staudinger, 1890, loc. cit. 3 : 338, pi. 3, fig. 8. 



PSEUDERCHIA Kirby, 1892, Syn. Cat. Lep. Het. 1 : 410. Type-species through Section (i) 

 (replacement names) of Article 67 : Erchia extranea Walker, 1854, List Spec. lep. Ins. 

 Brit. Mus. 2 : 357. 



The taxon represented by the nominal species Erchia extranea Walker together with its 

 generic name Erchia Walker, was (as explained in the note on that generic name) completely 

 overlooked until recently. This was due mainly to the fact that Walker, the author of these 

 names, and Kirby, the author of the replacement name Pseitderchia, erroneously believed 

 that the taxon Erchia extranea was a moth, whereas it is in fact a Riodinid butterfly. It is 

 now subjectively identified with the taxon represented by the older-established nominal 

 species Limnas barca Hewitson, [1853]. 



The name Pseuderchia was introduced as a replacement for Erchia Walker, 1854, which is 

 invalid under the Law of Homonymy. 



PSEUDERESIA Butler, 1874, Trans, ent. Soc. Lond. 1874 : 532. Type-species by original 

 designation : Pseuderesia catharina Butler, 1874, ibid. 1874 : 532, pi. 11, figs 4, 5. 



The taxon represented by the nominal species Pseuderesia catharina Butler is currently 

 treated subjectively on taxonomic grounds as being the same as that represented by the 

 older-established nominal species Pentila eleaza Hewitson, [1873] (///. exot. Butts 5 : [86], 

 pl- [45]. ngs 11, 12 6*).
