GENERIC NAMES OF BUTTERFLIES 421 



that name on the Official Index of Rejected and Invalid Generic Names in Zoology, it took the 

 opportunity also to place on that Index the spelling Sycionia, allotting it the Name No. 381. 



SYKOPHAGES Martin, 1903, Iris 16 : 81. Type-species by selection by Hemming (4935, 

 Stylops 4:2): Papilio thyonneas Cramer, [1779], Uitl. Kapellen 3 (19) : 46, pi. 220, figs E, F. 

 The name Sykophages Martin is invalid, as it is a junior objective synonym of Cyrestis 

 Boisduval, [1832]. 



SYMBRENTHIA Hiibner, [1819], Verz. bekannt. Schmett. (3) : 43. Type-species by mono- 

 typy : Symbrenthia hippocle Hiibner, [1819], ibid. (3) : 43. As defined by the specimen 

 figured as fig. C on plate 220 in volume 3 of Hiibner's Uitl. Kapellen and named Papilio 

 hippoclus on page 46 of that volume, that spe< imen having been selected by Hemming (1964, 

 Annot. lep. (3) : 100) to represent the lectotype. 



The nominal species Symbrenthia hippocle was established by Hiibner on the basis of biblio- 

 graphical references to two previously established nominal species, of which Papilio hippoclus 

 Cramer, 1770" 1 [Uitl. Kapellen 3 (19) : 46, pi. 220, figs C, D) was the first. At the same 

 time that the specimen figured as fig. C on Cramer's plate 220 and named Papilio hippoclus 

 on page 46 of volume 3 of Cramer's work was selected by 1 lemming to represent the lectotype 

 of Symbrenthia hippocle Hiibner, the same specimen was selected to represent also the lecto- 

 type of Papilio hippoclus Cramer, these names becoming therefore objective synonyms of one 

 another. 



SYMETHA Horsefield, [1829], Descr. Cat. lep. Ins. Mus. P.. India Coy (2) : pi. [2]. Type- 

 species by monotypy : Symetha pandu Horsfield, [1829], ibid. (2) : pi. 2, figs 2, 2a. 



The name Symetha was first published by Horsfield in 1828 in Part 1 ( : 59) of his Descr. Cat. 

 in a list of genera, but, as so published, it has no status in nomenclature, having been published 

 without a diagnosis and without any cited nominal species. 



The taxon represented by the nominal species Symetha pandu is currently treated subject- 

 ively on taxonomic grounds ;is a form of the taxon represented by the nominal species Papilio 

 symethus Cramer, [1777] {Uitl. Kapellen 2 (13) : 84, pi. 149, figs B, C). 



SYMMACHIA Hiibner, [1819], Verz. bekannt. Schmett. (2) : 26. Type-species by selection 

 by Scudder (1875, Proc. amer. Acad. Arts Sci., Boston 10 : 272) : Symmachia probetrix 

 Hiibner, [1819], ibid. (2) : 26. 



The name Symmachia probetrix Hiibner was introduced as a replacement for the name 

 Papilio probetor Stoll, [1782] (Uitl. Kapellen 4 (33) : 209, pi. 390, fig. 1). This action of Hiib- 

 ner's was quite uncalled for, the name probetor Stoll being an available name in no need of 

 replacement. 



SYMMACHIA Sodovskii, 1837, Bull. Soc. imp. Nat. Moscou 1837 (6) : 82. Type-species 

 through Section (i) (replacement names) of Article 67 : Papilio comma Linnaeus, 1758, 

 Syst. Nat. (ed. 10) 1 : 484. 



Sodovskii introduced the name Symmachia quite unnecessarily as a replacement of Hesperia 

 Fabricius, 1793. 



The name Symmachia Sodovskii is invalid, (a) because it a junior homonym of Symmachia 

 Hiibner, [1819], and (b) because it is a junior objective synonym of Hesperia Fabricius, 1793. 



SYMMACHLAS Hiibner, [1821], Samml. exot. Schmett. 2 : pi. [122]. Type-species by mono- 

 typy : Papilio nigrina Fabricius, 1775, Syst. Ent. : 475. 



SYMMACHLOS Klots, 1933, Ent. amer. (n.s.) 12 : 153, 204 (an Incorrect Subsequent Spelling 

 of Symmachlas Hiibner, [1821]). 



SYMPHAEDRA Hiibner, 1818, Zutr. z. Samml. exot. Schmett. 1 : 7. Type-species by selection 

 by Scudder (1875, Proc. amer. Acad. Arts Sci., Boston 10 : 272) : Symphaedra alcandra 

 Hiibner, 1818, ibid. 1 : 7, pi. [i], figs 1, 2, [a generic name which by a direction given by the 

 Commission under its Plenary Powers is not available for use in preference to Euthalia Hiibner, 

 [1819] (type-species : Papilio lubentina Cramer, [1777]) but available for use by any specialist 

 who does not consider the type-species of these two genera to be congeneric with one another] .
