GENERIC NAMES OF BUT I ERFLIES 413 



SINTHUSA Moore, 1884, /. asiat. Soc. Bengal, Pt II, 53 (1) : 33. Type-species by original 

 designation : Thecla nasaka Horsfield, [1829], Descr. Cat. lep. Ins. Mtts. East India Coy 

 (2) : 91. 



SIPROETA Hiibner, ! 1823], Samml. exot. Schmett. 2 : pi. [48]. Type-species by monotypy : 

 Siproeta trayja Hiibner, [1823], ibid. 2 : pi. [48]. 



SIRONIA Hiibner, [1823], Zutr. z. Samml. exot. Schmett. 2 : 31. Type-species by monotypy : 

 Sironia tithia Hiibner, ibid. 2 : 31, pi. [68], figs 391, 392. 



SISEME Westwood, [ 10th Oct. 1851], in Doubleday, Gen. diurn. Lep. (2) : pi. 72, fig. 10. 

 Type-species by monotypy : Siseme alectryo Westwood, [10th October 1851], in Doubleday, 

 ibid. (2) : pi. 72, fig. 10 [in text (: 462) published on 5th Dec. 1851 enumerated but with no 

 description]. 



Scudder, not realizing that plate 72 was published before the text, in which the above and 

 one other species were placed in this genus, seta ted Siseme alectryo Westwood as the type- 

 species. No harm came of thiN ai tkm, because, as noted above, that species was already the 

 type-species by monotypy. 



SIT A Herrich-Schaeffer, 1864, CorrespBl. zool.-min. Ver. Regensburg 18 : 102 [repaged offprint 

 as Prodromus 1 : 14]. Type-species by subsequent designation under Article 69(a) (ii) by 

 Hemming (1964, Annot. lep. (4) : 120) : Neorina sita Felder (C.) tV Felder (li.), 1859, Wien 

 ent. Monats. 3 : 403. 



Herrich-Schaeffer established this genus in a key, placing it between / ntirrhaea Hiibner 

 (genus 19) and Hipio Hiibner (genus 21). No species were cited for any of the genera in the 

 key, this being left for the later treatment of these genera in the main text. The portion of 

 the text relating to the genera cited in this key was published in [865 (he. cit. 19 : 71). Here 

 Herrich-Schaeffer omitted all reference to his genus Sita, inserting at the point where it should 

 have appeared the genus Neorina Doubleday re< te Westwood], in which he placed Neorina 

 hilda Westwood (the type-species of Neorina) and Neorina sita. There can be no doubt in 

 the circumstances that, when he established the nominal genus Sita, if was his intention to 

 include in it the species Neorina sita, which would thus have become the type-species by abso- 

 lute tautonymy. However, in view of the fact that Herrich-Schaeffer made no mention of 

 the name Sita when later he dealt with the genus Neorina, it cannot be claimed that Neorina 

 sita was one of the originally included species of Sita. It has to be admitted in fact that the 

 generic name Sita Herrich-Schaeffer was published without any nominal species being cited 

 as belonging to the genus. In order to provide this generic name with a definite place in the 

 literature I designated Neorina sita .is type-species under the provisions of Article 67 (a) (ii). 

 The name Sita Herrich-Schaeffer is invalid, as it is a junior homonym of Sita Semper, 1862 

 (J. Conch. 10 : 143). 



The taxon represented by the nominal species Neorina sita is currently treated subjectively 

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

 species Mycalesis (?) himachala Moore, 1857 (in Horsfield & Moore, Cat. lep. Ins. Mas. East 

 India Coy (1) : 234, the type-species of Ethope Moore, 1866). 



SITHON Hiibner, [1819], Vers, bekannt. Schmett. (5) : 77. Type-species by selection by 

 Scudder (1875, Proc. amer. Acad. Arts Set., Boston 10 : 269) : Papilio nedymond Cramer, 

 [1780], Uitl. Kapellen 4 (25) : 19, pi. 299, figs. E, F. 



SLOPERIA Tutt, [1906], Nat. Hist. Brit. Butts 1 : 218. Type-species by original designation : 

 Hesperia poggei Lederer, 1858, Wien. ent. Monats. 2 : 141. 



The taxon represented by the nominal species Hesperia poggei Lederer is commonly con- 

 sidered to be congeneric with that represented by the nominal species Papilio proto Esper, 

 [1805-1808], the type-species of the genus Syriclitus Boisduval, [1834] ; that species is also the 

 type-species of the later-established nominal genus Muschampia Tutt, [1906], the name of 

 which is now seen to be a junior objective synonym of Syrichtus Boisduval. (It may be useful 

 to note for historical purposes that prior to the recognition of the fact that Papilio proto is the 

 type-species of Syrichtus Boisduval, there was a problem as to the relative status to be accorded
