THRACIDES Hiibner, [1819], Verz. bekannt. Schmett. (7) : 105. Type-species by selection by 

 Scudder (1875, Proc. amer. Acad. ArtsSci., Boston 10 : 282) : Papilio phidon Cramer, [1779], 

 Uitl. Kapellen 3 (21) : 88, pi. 245, figs F, G. 



THRENODES Hewitson, 1870, Equatorial Lep. Buckley (4) : 58. Type-species by monotypy : 

 Threnodes coenoides Hewitson, 1870, ibid. (4) : 58. 



The name Threnodes Hewitson is invalid, as it is a junior homnym of Threnodes Dupochel, 

 1845 (Cat. mith. Lipid. Europ. (2) : 196) and also of Threnodes Guenee, 1854 (Roret's Suite a 

 Buffon), Hist. nat. Ins. 8 (Delt. & Pyr.) : 184. It has been replaced by the name Nahida 

 Kirby, 1871. 



THRIX Doherty, 1891, /. asiat. Soc. Bengal Pt II, 60 (1) : 35. Type-species by monotypy : 

 Neocheritra gama Distant, 1886, Rhop. malayan. : 462, text-fig. 128. 



THYCA Wallengren, 1858, Ofvers. YetenshAkad. Fork., Stockh. 15 : 76. Type-species by 

 selection by Scudder (1875, Proc. amer. Acad. Arts Sci., Boston 10 : 282) : Papilio aganippe 

 Donovan, 1805, Epit. nat. Hist. Ins. New Holland : pi. 29 q*- 



The name Thyca is invalid, as it is a junior homonym of Thyca H. &. A. Adams, 1858 (Gen. 

 Rec. Moll. 1 : 372). 



THYMALE Oken, 1815, Lehrbuch Naturgesch. 3 (Zool.) (1) : 757, 758. Type-species by selec- 

 tion by Hemming (1933, Entomologist 66 : 225) : Papilio tages Linnaeus, 1758, Syst. Nat. (ed. 

 10) 1 : 485. 



Oken placed all the Hesperiids in the genus Erynnis Schrank, 1801 ; under that name he 

 cited ( : 757) three names as synonyms, one of these being Thymale, no authors' names being 

 cited for any of these names. He divided the genus ( : 758) into two groups, to the first of 

 which he assigned the name Thymale. Although it is impossible to be certain, it is most likely 

 that the name Thymale Oken is an Incorrect Subsequent Spelling of Thymele Fabricius, 1807. 

 In any case by the type-selection specified above the name Thymale Oken is a junior objective 

 synonym of Thymele Fabricius, which in its turn is itself a junior objective synonym of 

 Erynnis Schrank, 1801. 



Even if Thymale Oken had been otherwise available it would nevertheless have been 

 invalid owing to the fact that in 1956 (Opin. int. Comm. zool. Nom. 14 : 1-42) the Commission 

 by its Opinion 417 rejected Oken's Lehrbuch for nomenclatorial purposes. 



THYMELE Fabricius, 1807, Mag. f. Insektenk. (Illiger) 6 : 287. Type-species by selection by 



Westwood (1840, Introd. Class. Ins. 2, Svn. : 88) : Papilio tages Linnaeus, Syst. Nat. (ed. 10) 



1 : 485- 

 THYMELICUS Hiibner, [1819], Verz. bekannt. Schmett. (8) : 113. Type-species by selection 



by Butler (1870, Ent. mon. Mag. 7 : 94) : Papilio acteon Rottemburg, 1775, Der Natur- 



forschev 6 : 30. 



THYMELINUS Stephens, 1875, ///. Brit. Ent., Haustellata 4 : 405 (an Incorrect Subsequent 

 Spelling of Thymelicus Hiibner, [1819]). 



Formerly it seemed to me — incorrectly, as I now see — that this might have been published 

 by Stephens independently as the name of a new genus and, I selected (1933, Entomologist 66 : 

 200) Papilio acteon Rottemburg, 1775, as type-species, my purpose being thereby to dispose of 

 this name by making it a junior objective synonym of Thymelicus Hiibner, [1819]. 



THYMPIA Moore, [1893], Lep. hid. 2 (14) : 57, 58. Type-species by original designation : 

 Papilio baldus Fabricius, 1775, Syst. Ent. : 829. 



THYRANOTA Stichel, 1901, in Wytsman's Gen. Ins. 112 (A) : 22 (an Incorrect Original 

 Spelling of Thysanota Stichel). 



THYRIDIA Hiibner, 1816, Verz. bekannt. Schmett. (1) : 9. Type-species by selection by 

 Scudder (1875, Proc. amer. Acad. Arts Sci., Boston 10 : 283) : Papilio psidii Linnaeus, 1758, 

 Syst. Nat. (ed. 10) 1 : 466.
