GENERIC NAMES OF BUTTERFLIES 355 



PETREUS Swainson, [1833], Zool. Illustr. (2) 3 : pi. no. Type-species by monotypy : Papilio 

 thetys Fabricius, 1777, Gen. Ins. : 264. 



The taxon represented by the nominal species Papilio thetys Fabricius is currently treated 

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

 established nominal species Papilio petreus Cramer, [1776] (Uitl. Kapellen 1 (8) : 138, pi. 87, 

 figs D, E.). 



The name Petreus Swainson is invalid, as it is a junior objective synonym of Athena Hiibner, 

 [1819]. 



PHAEDIN ( S Skinner, 1905, J.N.Y. ent. Soc. 13 : 115 (an Incorrect Subsequent Spelling of 

 Pkoedinits Godman & Salvin, [1894]). 



PHAEDRA Horsfield, [1829], Descr. Cat. lep. Ins. Mus. East India Coy (2) : 123. Type- 

 species by selection by Hemming (1934, Gen. Names hoi. Butts 1 : 120) : Phaedra terricola 

 Horsfield, ibid. (2) : 124. 



Horsfield placed in this genus two now nominal species, the above species and Phaedra 

 insularis (: 124). Kirby (1871, Syn. Cat. diurn. Lep : 418-419) cited both under the name 

 Curetis thetys (Drury). On the basis of this subjective synonymy Scudder concluded (1875, 

 Proc. amer. Acad. Arts Sci., Boston 10 : 246) that this genus should be looked upon as mono- 

 typical with Papilio thetys Drury, [1773], as type-species. The first of these conclusions was 

 incorrect, because (as shown above) Horsfield included two nominal species in this genus ; 

 the second, because Papilio thetys Drury was not one of the originally included nominal 

 species and was therefore ineligible for selection as type species. This genus remained with- 

 out a validly fixed type-species until in 1934 I so selected Phaedra terricola Horsfield. 



The taxon represented by the nominal species Phaedra terricola Horsfield is currently 

 considered subjectively on taxonomic grounds to represent the same taxon as that represented 

 by the older-established nominal species Papilio thetys Drury, [1773] (III- nat. Hist. 2 : index 

 et 16, pi. 9, figs 3, 4), as it was in the time of Kirby (1871) and Scudder (1875). 



PHAEDROTES Scudder, 1876, Bull. Buffalo Soc. nat. Sci. 3 : 115. Type-species by original 

 designation : Lycaena catalina Reakirt, 1866, Proc. Acad. nat. Sci. Philad. 1866 : 244. 



The taxon represented by Lycaena catalina Reakirt is currently treated subjectively on 

 taxonomic grounds as being the same as that represented by the older-established nominal 

 species Lycaena piasus Boisduval, 1852 {Ann. Soc. ent. l-'i . (2) 10 : 299). 



PHAEDYMA Felder (C), 1861, Nova Acta Leop. Carol. 28 (Xo. 3) : 31. Type-species 

 by selection by Scudder (1875, Proc. amer. Acad. Arts Sci., Boston 10 : 247) : Papilio 

 heliodora Cramer, [1779], Uitl. Kapellen 3 (18) : 35, pi. 212, figs E, 1*' 



PHAENOCHITONIA Stichel, 1910, Berl. ent. Z. 55 (1/2) : 51. Type-species by selection 

 by Stichel (1911, in Wytsman's Gen. Ins. 112 (B) : 239) : Papilio cingulus Stoll, [1790], 

 Aanhangs. Werk Uitl. Kapellen Pieter Cramer : 61, pi. 13, fig. 4. 



PHALAENOSOMA Rippon, [1902-1906], Icon. Ornithopt. 2 : 121. Type-species by mono- 

 typy : Troides chimaera Rothschild, 1904, Novit. zool. 11 : 311, pi. 3, fig. 25 9- 



PHALANTA Horsfield, [1829], Descr. Cat. lep. Ins. Mus. East India Coy (2) : pi. 7. Type- 

 species by monotypy : Papilio phalantha Drury, [1773], ///. nat. Hist. 1 : index et 41, 

 pi. 21, figs 1, 2. 



PHANES Godman, [1901], in Godman & Salvin, Biol, centr.-amer., Lep. Rhop. 2 : 741. Type- 

 species through Section (i) (replacement names) of Article 67, and through Section (a) (mis- 

 identified type-species) of Article 70 provisionally applied pending a decision by the Inter- 

 national Commission on Zoological Nomenclature on an application submitted : Thracides 

 aletes Geyer, [1832], in Hiibner, Zutr. z. Samml. exot. Schmett. 4 : 31, pi. [126], figs 731, 732. 



The name Phanes was introduced by Godman to replace the name Phanis published by 

 himself in the previous year (1900), that name being invalid under the Law of Homonymy. 



The name Phanes, as a replacement name, automatically takes as its type-species the species
