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

 species Papilio protumnus Linnaeus, 1764 (Mus. Lud. Ulr. : 340). 



Overlooking Scudder's selection of the above species as type-species Tutt, (1906, Ent. Rec. 

 18 : 131) selected as type-species Papilio balhcs Fabricius, 1787, the second of the two species 

 placed by Hiibner in his genus Thestor. This incorrect action led to the use for a time of the 

 name Thestor for a Palaearctic genus, which was unfortunate because, as represented by its 

 true type-species, the genus Thestor is confined to the Ethiopian Region, Papilio protumnus 

 occurring only in South Africa. 



THIEMEIA Weymer, [1912], in Seitz, Grossschmett. Erde 5 : 267. Type-species by selection 

 by Hemming (1943, Proc. R. ent. Soc. Lond. (B) 12 : 25) : Pronophila phoronea Doubleday, 

 [1849], Gen. diurn. Lep. (2) : pi. 60, fig. 1 [text by Westwood (loc. cit. (2) : 368) published in 

 March 1851]. 



THIMEIA Gaede, 1931, in Strand's Lep. Cat. 46 : 511 (an Incorrect Subsequent Spelling of 

 Tliiemeia Weymer, [19 12]). 



THIRIDIA Hiibner, 1818, Zutr. z. Samml. exot. Schmett. : 28 (an Incorrect Subsequent Spelling 

 of Thyridia Hiibner, 18 16). 



THISBE Hiibner, [1819], Verz. bekannt. Schmett. (2) : 24. Type-species by monotypy : 

 Papilio belise Stoll, | 1782 , in Cramer, Uitl. Kapellen 4 (32) : 171, pi. 376, figs E, F, 



The taxon represented by the nominal species Papilio belise Stoll is currently treated sub- 

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

 nominal species Papilio irenea Stoll, [1780], in Cramer, Uitl. Kapellen 4 (28) : 77, pi. 328, 

 figs C, D. 



THOAS Swainson, [1833], Zool. lllustr. (2) 3 : pi. 121. Type-species by tautonymy under 

 Article 68(d) : Papilio thoas Linnaeus, 1771, Mantissa Plant. 2 : 536. 



The name Thoas Swainson is invalid, as it is a junior objective synonym of Heraclides 

 Hiibner, [1819]. 



THOMARES Rambur, 1858, Cat. syst. Lipid. Andal. : 34 (an Incorrect Subsequent Spelling of 

 Tomares Rambur, 1840). 



THOON Godman, [1900], in Godman & Salvin, Biol, centr.-amer., Lep. Rhop. 2 : 259. Type- 

 species by original designation : Proteides modius Mabille, 1889, Le Naturaliste (2) 3 : 99, 

 fig. 2. 



THORAESSA Westwood, [1850], in Doubleday, Gen. diurn. Lep. (2) 1326 (invalid under 

 Article 11 (d) because published in a synonymy). 



This name was introduced by Westwood as " Thoraessa Boisduval MS. " in the synonymy 

 of Amathusia Fabricius, 1807. Prior to the introduction of the present (1961) text of the Code, 

 the question whether a name published in a synonymy did or did not possess any status in 

 nomenclature was matter of doubt. Accordingly, in order to ensure the relegation of Thoraessa 

 in synonymy without any chance of subsequent emergence, I selected in 1939 {Proc. R. ent. 

 Soc. Lond. (B) 8 : 133) Papilio phidippus Linnaeus, 1763 to be the type-species. In conse- 

 quence, even if Thoraessa Westwood had not been invalidated by having been published in a 

 synonymy, it would nevertheless have been invalid as a junior objective synonym of Amathusia 

 Fabricius, 1807, of which also the above species is the type-species. 



THORESSA Swinhoe, [1913], in Moore, Lep. ind. 10 (120) : 284. Type-species by original 

 designation : Pamphila masoni Moore, [1879], Proc. zool. Soc. Lond. 1878 (4) : 842, pi. 411, 

 fig. 6 <?. 



THORYBES Scudder, 1872, 4//; Ann. Rep. Peabody Acad. Sci. 1871 : 71. Type-species by 

 original designation : Papilio bathyllus Smith, 1797, in Abbot, Ins. Georgia 1 : 43, pi. 22. 

 The taxon represented by the nominal species Papilio bathyllus Smith is currently treated 

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

 established nominal species Papilio daunus Cramer, [1777] [Uitl. Kapellen 2 (11) : 44, pi. 126, 

 fig. F).
