GENERIC NAMES OF BUTTERFLIES 459 



XENICONYMPHA Novickij, 1923, Sborn. ent. Odd. mar. Mus. Praze 1 : 60. Type-species by 

 monotypy : Lasiommata leprea Hewitson, 1864, Trans, ent. Soc. Lond. (3) 2 : 249, pi. 16, 

 figs 6, 7. 



The name Xeniconympha Novickij is invalid, as it is a junior objective synonym oi 

 Nesoxenica YVaterhouse & Lyell, 1914. 



XENOPHANES Godman & Salvin, [1895], Biol, centr .-amer . , Lep. Rhop. 2 : 387. Type- 

 species by original designation : Papilio tryxus Stoll, [1780], in Cramer, Uitl. Kapellen 

 4(28) : 87, pi. 334, figs G, H. 



XINIAS Stichel, 1930, in Strand's Lep. Cat. 40 : 491 (an Incorrect Subsequent Spelling of 

 Xynias Hewitson, 1874). 



XISPIA I.indsey, 1925, Ann. ent. Soc. Amer. 18 : 106. Type-species through Section (i) 

 (replacement names) of Article 67 : Praxis quadrata Mabille, 1889, Le Naturaliste (2) 3 : 25. 

 The name Xispia was introduced by I.indsey to replace Praxis Mabille, 1889, which is 

 invalid under the Law of Homonymy. 



XOIS Hewitson, 1865, Trans, ent. Soc. Lond. (3) 2 (4) : 282. Type-species by monotypy : 

 Xois sesara Hewitson, 1865, ibid. (3) 2 (4) : 282, pi. 17, figs 3, 4. 



XYNIAS Hewitson, 1874, Descr. new Spec. Butts Buckley Bolivia : 17. Type-species by 

 monotypy : Xynias cynosema Hewitson, 1 S74, ibid. : 17. 



YANGUNA Watson, 1893, Proc. zool. Soc. Lond. 1893 : 10, 12. Type-species by original

 Equal. Lep. : 69. 



YASODA Doherty, [December 1880], /. asiat. Soc. Bengal, Ft II, 58 (4) : 410 nota, 425. Type- 

 species by monotypy : Lexura tripunctata Hewitson, [1863], ///. diurii. Lep., Lycaenidae 

 1 (text) : 26. 



Doherty gave a short diagnosis of this genus in the footnote to page 410, but cited no 

 included species. On page 425 he placed Loxura tripunctata Hewitson in this genus and, as 

 he cited no other species, that species is the type-species by monotypv. 



YASODA de Niceville, [February] 1890, Butts India Burmah Ceylon 2 : 20, 438. Type- 

 species by original designation : Loxura pita Horsfield, [1829], Descr. Cat. lep. hid. Mus. 

 East India Coy (2) : 122. 



This name is invalid under the Law of Homonymy, for (as will be seen from the particulars 

 given above) it was published at least four or five weeks after the publication of the name 

 Yasoda Doherty. 



It appears that de Niceville was unaware that the name Yasoda had actually been published 

 by Doherty, to whom he attributed this name in manuscript, at the same time printing a 

 short note on the genus which he had received from Doherty. 



YOMA Doherty, [1st October 1886], /. asiat. Soc. Bengal, Pt II, 55 : 258. Type-species by 

 original designation : Yoma vasuki [1st October 1886], ibid. 55 : 259. 



The taxon represented by the nominal species Yoma vasuki Doherty is currently treated 

 subjectively on taxonomic grounds as being a subspecies of the taxon represented by the 

 older-established nominal species Papilio sabina Cramer, [1780] {Uitl. Kapellen 4 (25) : 1 

 pi. 289, figs A, B ?, C, D 6"). 



YOMA de Niceville, [31st October 1886], Butts India Burmah Ceylon 2 : 245 nota. Type- 

 species by original designation : Yoma vasuki de Niceville, [31st October 1886], ibid. 2 : 247. 

 The history of the name Yoma, as published by de Niceville and Doherty respectively, 

 resembles closely that of the name Yasoda, as published independently by those authors, in 

 the manner described immediately above. In each case the name was first proposed by
