THEREUS Hubner, [1819], Verz. bekannt. Schmett. (5) : 79. Type-species by monotypy : 

 Papilio lausus Cramer, [1779], Uitl. Kapellen 3 (20) : 70, pi. 233, fig. E. 



THERITAS Hubner, 1818, Zutr. z. Samml. exot. Schmett. 1 : 31. Type-species by selection by 

 Scudder (1875, Proc. amer. Acad. Arts Sci., Boston 10 : 280) : Theritas mavors Hubner, 

 1818, ibid. 1 : 31, pi. [33], figs 189, 190. 



In the immediately following year ([1819], Verz. bekannt. Schmett. (5) : 80) the name 

 Theritas was republished by Hubner in exactly the same sense. 



THERIUS Billberg, 1820, Enum. Ins. Mus. Billb. : 75. Type-species by selection by Hem- 

 ming (1933, Entomologist 66 : 199) : Papilio apollo Linnaeus, 1758, Syst. Nat. (ed. 10) 1 : 65. 

 The name Therius Billberg is invalid, as it is a junior objective synonym of Parnassius 

 Latreille, 1804. 



THERMONIPHAS Karsch, 1895, Ent. Nachr. 21 : 298, 303. Type-species by original 

 designation : Thermoniphas plurilimbata Karsch, 1895, ibid. 21 : 303. 



Karsch established this nominal genus in a key on page 298 and there stated that its type- 

 species was the new Central African species cited above which he described on page 303 later 

 in the same paper. 



THERSAMONIA Verity, 1919, Ent. Rec. 31 : 28. Type-species by original designation : 

 Papilio thersamen Esper, [1784], Die Schmett. 1 (Bd 2) Forts. Tagschmett. : 176, pi. 89, 

 ng. 6 6"- 



THESPIA Wallengren, 1858, Ofvers. VetenskAkad. Forh., Stockh. 15 : 77. Type-species 

 through Section (i) (replacement names) of Article 67 : Ptychopteryx bohemani Wallengren, 

 1857, K. svenska VetenskAkad. Handl., Stockholm (n.f.) 2 (Pt 1) (No. 4) : 18. 



The taxon represented by the nominal species Ptychopteryx bohemani Wallengren is currently 

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

 established nominal species Teracolus subfasciatus Swainson, [1833] (Zool. Illustr. (2) 3 : pi. 



ii5)- 



The name Thespia was introduced as a replacement of the name Ptychopteryx Wallengren, 



1857- 

 THESPIEUS Godman, [1900], in Godman & Salvin, Biol, centr .-amer . , Lep. Rhop. 2 : 519. 

 Type-species by original designation : Hesperia dalmani (correction of dalman) Latreille, 

 [1824], Ency. me"th. 9 (Ins.) (2) : 747. 



The specific name of the type-species was published in the non-Latinized form " dalman " , 

 which, being a modern patronymic, is subject to automatic correction to " dalmani " under 

 Article 31. 



THESSALIA Scudder, 1875, Bull. Buffalo Soc. nat. Sci. 2 : 238, 265. Type-species by original 

 designation : Melitaea leanira Felder (C.) & Felder (R.), i860, Wien. ent. Monats. 4 : 106. 



THESTIAS Boisduval, [1836], (Roret's Suite a Buffon), Hist. nat. Ins., Spec. gen. Lepid. 1 : 590. 

 Type-species by selection by Butler (Cist. ent. 1 137,48) : Papilio pyrene Linnaeus, 1764, Mus. 

 Lud. Ulr. : 241. 



Butler first identified Thestias Boisduval (: 37) with Ixias Hubner and then designated 

 Papilio pyrene Linnaeus as the type-species for that genus (: 148). Ixias Hubner is an 

 available name and Thestias is accordingly invalid as a junior objective synonym.

 Scudder (1875, Proc. amer. Acad. Arts Sci., Boston 10 : 281) : Papilio pholeus Cramer,
