GENERIC NAMES OF BUTTERFLIES 85 



The name Caecina Hevvitson, 1868 is invalid, as it is a junior homonym of the name Caecina 

 Stal, 1863, Ann. Soc. ent. Fr. (4) 3 : 48. It was replaced by Lindsey in 1925 by the name 

 Ocyba. 



CAENIDES Holland, 1896, Proc. zool. Soc. Lond. 1896 : 85. Type-species by selection by 

 I.indsey (1925, Ann. ent. Soc. Amer. 18 : 81) : Hesperia dacela Hewitson, 1876, Ann. Mag. 

 nat. Hist. (4) 18 : 451. 



CAENYRA Butler, 1868, Cat. diurn. Lep. Satyridae Brit. Mtts. : 147 (an Incorrect Subsequent 

 Spelling of Coenyra Hewitson, 1865). 



CAEROIS Hiibner, [1819], Verz. bekannt. Schmett. (4) : 56. Type-species by monotypy : 

 Caerois arcesilae Hiibner, [1819], ibid. (4) : 56. 



The name Caerois arcesilae Hiibner was an unnecessary nom. nov. for what Hiibner called 

 [Papilio] arcesilaus " Cramer " ; Cramer however did not publish this as a new name, what he 

 did being to provide a figure of Papilio arcesilaus Sulzer, 1776 (Gesch. Ins. : 142, pi. 14, fig. 4). 

 This nominal species is currently considered subjectively on taxonomic grounds to represent 

 the same taxon as that represented by the older-established nominal species Papilio chorinaeus 

 Fabricius, 1775 (Syst. Ent. : 484). 



CAEROUS Herrich-Schaeffer, 1865, CorrespRl.-zool.-mui Vet Regensbttrg 19 : 73 (an Un- 

 justified Emendation of Caerois Hiibner, [1819] and therefore an invalid name). 



CAERULEA Forster, 1938, Mitt, mitnehn. ent. Ges. 28 : 108. Type-species by original desig 

 nation : Lycaena coeligena Oberthur var. coelestis Alphe^raky, 1897, in Romanoff, 

 Mim. Lip. 9 : 113. 



CAICELLA Hemming, 1934, Slylops 3 : 144. Type-species through Section (i) of Article 67 : 

 Eudamus caicus Herrich-Schaeffer, 1869. CorrespBl. zool. -win. \'er. Regensbttrg 23 : 188. 



Tins name was introduced as a replacement for the name- Phoedinus Godman & Salvin, 

 [1894], which is invalid under the Law of Homonymy. Prior to the publication of the name 

 Caicella, the name Phoedinus Godman & Salvia had already been replaced by the name 

 Anaperits Mabille & Boullet, 1919, but unfortunately that name also was invalid under the 

 Law of Homonymy. 



CALAIDES Hiibner, [1819], Verz. bekannt. Schmett. (6) : 86. Type-species by selection by 

 Rothschild & Jordan (1906, Novit. zool. 13 : 358) : Papilio androgeos Cramer, [1775], 

 Uitl. Kapellen 1 (2) : 24, pi. 16, figs C, D. 



In 1875 {Proc. amer. Acad. Arts Sci. Boston 10 : 129) Scudder selected Papilio androgeos 

 Cramer, [1776] (Uitl. Kapellen 1 (8) : 142, pi. 91, figs A, B), but that selection is invalid, 

 because this was not one of the species originally included in this genus by Hiibner. 



The name Calaides Hiibner was published on the same date (and in the same work) as the 

 name Heraclides I liibner, and in consequence the relative precedence to be accorded to these 

 names depends on the choice of the First Reviser. This choice was made by myself in 1964 

 (Annot. lep. (3) : 85), when I chose the name Heraclides Hiibner to take precedence over the 

 name Calaides Hiibner. 



CALAIS Boisduval, [1836], (Roret's Suite a Buffon), Hist. nat. Ins., Spec. gen. L6pid. 1 : 584. 

 Type-species through Section (i) (replacement names) of Article 67 : Pontia chrysonome Klug, 

 1829, in Ehrenberg, Sym. Phys. Ins. 1 : signature G, 4, pi. 7, figs 9, 10 <$, 11 $. 



Boisduval introduced the names Idmais and Calais simultaneously, but adopted the name 

 ldmais, sinking Calais as a synonym, adding the words " nobis olim " . He explained on the 

 following page (: 585) that he had formerly applied this name to the present genus but had 

 come to the conclusion that it was inconvenient to have a genus bearing a name consisting of 

 the same word as the specific name (of one of its best-known species, namely Papilio Calais 

 Cramer, [1775] (Uitl. Kapellen 1 (5) : 84, pi. 53, figs C, D)). He had therefore decided to 

 substitute the name Idmais for the name Calais which he had previously proposed to intro- 

 duce. These two nominal genera are thus absolutely identical, and Pontia chrysonome Klug,
