CYRESTIS Boisduval, 1832, nzd'Urville, Voy. " Astrolabe ", Ent. 1 (Lep.) : 117. Type-species 

 by selection by Scudder (Proc. amer. Acad. Arts Sci., Boston 10 : 152) : Papilio thyonneus 

 Cramer, [1779], Uitl. Kapellen 3 (19) : 46, pi. 220, figs E, F. 



CYRINA Hemming, 1939, Proc. R. ent. Soc. Lond. (B) 8 : 39. Type-species through Section 

 (i) (replacement names) of Article 67 : Hesperia cyrina Hewitson, 1876, Ann. Mag. >iat. 

 Hist. (18) 4 : 450. 



The name Cyrina was introduced as a replacement for Cretens de Niceville, 1895, because the 

 latter was a junior homonym of Creteus Westwood, [1852]. The situation as regards these 

 names was changed when the revised Code was published in 1961, for Article 11(d) provides 

 that a name published in a synonymy — as Creteus Westwood was published —does not accpiire 

 the status of availability thereby. The present position is therefore that the name Crelriis 

 Westwood possesses no status in nomenclature and in consequence does not invalidate the 

 name Creteus de Niceville under the Law of Homonvmy ; that Creteus de Niceville is seen to 

 be an available name ; and that Cyrina Hemming, published as a replacement for de Nw e- 

 ville's Creteus, becomes invalid as a junior obje< tive synonym of that name. 



CYSTINEURA Boisduval, [1836], (Roret's Suite a Buffon), Hist. nat. his., Consid. g6n. 

 Lepid. 1 : pi. 9 [ = pl. 5B], fig. 1. Type-species by monotypy : Papilio hersilia Fabricius, 

 1777, Gen. Ins. : 265. 



The taxon represented by the nominal species Papilio hersilia is currently treated subjec- 

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

 nominal species Papilio dorcas Fabricius, 1775 (Syst. Ent. : 508). 



CYTHA ERIAS Weymer, 1890, in Reiss & Stubel, Reisen inSud-Amer., Lepid. : 53 (an Incorrect 

 Subsequent Spelling of Cithaerias Hiibner, [1819]). 



CZAKIA Kremky, 1925, Ann. tool. Mas. polon. Hist. nat. 4 (3) : 192. Type-species by original 

 designation : Melinaea mneme (Linnaeus) var. mediatrix Weymer, 1890, Stett. ent. //;■ 

 51 : 282. 



It is currently considered — e.g. by Fox, i960 (Trans, amer. ent. Soc. 86 : 124—126) that 

 through a misinterpretation of the taxon represented by the nominal spec k > Papilio mneme 

 Linnaeus, 1763 (Amoen. acad. 6 : 403), Weymer took the view that the taxon now regarded on 

 the basis of the surviving type-specimen as the true Papilio mneme Linnaeus was still without a 

 name and it was to this taxon that Weymer gave the name mediatrix. 



DABASA Moore, 1888, Descr. new ind. Lep. Coll. Atkinson (3) : 283. Type-species by original 

 designation : Papilio gyas Westwood, 1841, Arcana ent. (3) : 41, pi. 11, fig. 1 <J. 



DACALANA Moore, June 1884, /. asiat. Soc. Bengal, Pt II, 53 (1) : 36. Type-species by 



original designation : Amblypodia vidura Horsfield, [1829], Descr. Cat. lep. Ins. Mus. 



East India Coy (2) : 113 (figured by Horsfield in the same work as T/iecla vidura on pi. i, 



figs 6, 6a o")- 

 DACALANA Distant, [August] 1884, Rhop. malayana : 233, 240. Type-species by original 



designation : Amblypodia vidura Horsfield, [1829]. 



Distant said that Moore had informed him of his intention to establish this genus with the 



above species as type-species. Distant clearly believed that it was still only a manuscript 



name and in the work cited above he assumed full responsibility for its publication. 



The name Dacalana Distant is invalid as a junior homonym of Dacalana Moore, published 



two months earlier. It is also a junior objective synonym of Dacalana Moore, having the 



same species as type-species.
