GENERIC NAMES OF BUTTERFLIES 105 



CEPHRENES Waterhouse & Lyall, 1914, Bulls Australia : 8, 199, 206. Type-species by 

 original designation (: 206) : Hesperia sperthias Felder (C), 1862, Verh. zool.-bot. Ges. 

 Wien 12 : 492. 



The taxon represented by the nominal species Hesperia sperthias Felder is currently treated 

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

 species Hesperia augiades Felder (C), i860 (S.B. Akad. Wiss. Wien 40 : 461). 



CEPORA Billberg, 1820, Enum. Ins. Mus. Billb. : 76. Type-species by selection by Scudder 

 (1875, Proc. amer. Acad. Arts Sci., Boston 10 : 138) : Papilio coronis Cramer, [1775] 

 Uitl. Kapellen 1 (4) : 69, pi. 44, figs B, C. 



The taxon represented by the nominal species Papilio coronis Cramer is currently treated 

 subjectively on taxonomic grounds as being the same as that represented by the nominal 

 species Papilio nerissa Fabricius, 1775 (Syst. Ent. : 471). As these names were both pub- 

 lished in the year 1775 and there was no sure evidence as to which was the first to be published, 

 there has always been some doubt as to which of these names should be used in preference 

 to the other. For the most part however authors have used the specific name nerissa Fab- 

 ricius rather than the name coronis Cramer. The underlying question here involved affected 

 a considerable number of pairs of names, not only names published by Fabricius and Cramer 

 in 1775 but also by other authors published in that year, notably von Rottemburg and Denis 

 & Schiffermiiller. This question was considered in a preliminary way in 1948 by the Commis- 

 sion which directed that a detailed investigation should be carried out and a report submitted 

 to it for consideration. The report so called for was considered by the Commission in 1957. 

 The decision then taken by the Commission was later embodied in the Commission's Opinion 

 516 (1958, Opin. int. Comtn. zool. Nom. 19 : 1-44). In that Opinion the Commission 

 ruled, inter alia, that the Systema Entomologiae of Fabricius is to be treated as having priority 

 over those Parts of Cramer's Uitl. Kapellen published in 1775. Under this ruling the 

 specific name nerissa Fabricius, 1775, published in the combination Papilio nerissa, takes 

 precedence over the name coronis Cramer, [1775], published in the combination Papilio 

 coronis. Thus, on the subjective taxonomic view indicated above, the name nerissa Fabricius, 

 1775, is the oldest available specific name subjectively applicable to the type-species of the 

 present genus. 



CERATINIA Hiibner, 1816, Verz. bekannt. Schmett. (1) : 10. Type-species by selection by 

 Scudder (1875, Proc. amer. Acad. Arts Sci., Boston 10 : 138) : Nereis neso Hiibner, [1806], 

 Samml. exot. Schmett. 1 : pi. [5]. 



It should be noted that for a time there was a certain amount of misuse of the generic name 

 Ceratinia, following the erroneous action of Haensch in 1909 (in Seitz, Grossschmett. Erde 5 : 

 128) in applying this name to the genus of which the true name is Hypothyris Hiibner, 1821, 

 while calling the true genus Ceratinia by the name Calloleria Godman & Salvin, [1879]. 



CERATONIA Boisduval, 1870, Consid. Lipid. Guatemala : 32. Type-species by selection by 



Kirby, [1871], in Zool. Rec. 7 (year 1870) (Ins.) : 383 : Ithomia stella Hewitson, [1854], 77/. exot. 



Butts 1 : [36], pi. [18], fig. 52. 



This name is invalid, as it is a junior homonym of Ceratonia Costa, 1839 (Corresp. Zool. 1 : 



33)- 

 CERATRICHIA Butler, 1869, Cat. diurn. Lep. Fabricius : 274. Type-species by original 



designation : Papilio nothus Fabricius, 1787, Mantissa Ins. 2 : 88. 



CERCYONIS Scudder, 1875, Bull. Buffalo Soc. nat. Sci. 2 : 235, 241. Type-species by original 

 designation : Papilio alope Fabricius, 1793, Ent. syst. 3 (1) : 229. 



Scudder stated that the name Cercyonis was a manuscript name of Speyer's. 



CETHOSIA Fabricius, 1806, Mag. f. Insektenk. (Illiger) 6 : 280. Type-species by selection by 

 Latreille (1810, Consid. gin. Anim. Crust. Arachn. Ins. : 440) : Papilio cydippe Linnaeus, 

 1767, Syst. Nat. (ed. 12) 1 (2) : 776. 



The name Papilio cydippe Linnaeus, 1767, has been used almost continuously throughout
