GENERIC NAMES OF BUTTERFLIES 159 



Bryk's object in establishing this generic name was to provide a name for what Doubleday 

 ([1847], Gen. diurn. Lep. (1) : 99-100) had denominated as " Sectio I " of the genus Tithorea 

 which he then established. 



EMATURGINA Rober, 1903, Stett. ent. Ztg 64 : 347. Type-species by original designation: 

 Ematurgina mabillei Rober, 1903, ibid. 64 : 347. 



The taxon represented by the nominal species Ematurgina mabillei Rober is currently 

 treated subjectively as being a subspecies of that represented by the nominal species Baeotis 

 bifasciata Mengel, 1902 (Ent. News 13 : 77, pi. 8, figs 7, 8). 



EMESIS [Illiger], 1807, Allgem. Lit. Ztg, Halle, [Jena] 1807 No. 2 : 1180. Type-species by 

 monotypy : Papilio phareus Cramer, [1777], Uitl. Kapellen 2 (15) : 113, pi. 170, fig. C. 



This nominal genus is based exclusively upon the figures published in [1807] (Satnml. 

 exot. Schmett. 1 : pi. [32]) under the name Litnnas pliarea. As Hiibner's figures show, this was 

 not a newly-established nominal species of Hiibner's but was the species to which in 1777 

 Cramer had given the name Papilio phareus. 



The present is one of a number of generic names published anonymously by Illiger in 1807 

 shortly before being published by Fabricius for entirely different species. Papilio phareus, 

 the type-species of the present genus, is the type-species also of the well-known genus Mi 

 Doubleday, 1847. If it had been necessary to apply the ordinary rules in the present case, 

 it would have been necessary to sink the name Mesene Doubleday as a junior objei 

 synonym of Emesis [Illiger], while and this would have been far more important the 

 extremely well-known Emesis Fabricius would have had to be abandoned .is a junior homo- 

 nym of Emesis [Illiger]. It was considered that these ( hanges would give rise to an insup- 

 portable state of confusion. It was decided therefore that an approach should be made to the 

 Commission with a request for the grant of relict' under tin- Plenary Powers. 



It was decided that the Commission should he asked to ileal simultaneously with all the 

 names published anonymously by Illiger in 1807 that are senior homonyms of well-known 

 names published by Fabricius in the same yen' Among these names were Apatura [Illiger] 

 and Brassolis [Illiger], both of which have already been discussed in detail. It is not necessary 

 therefore to pursue in detail the subsequent history of the name Emesis I Illiger. The decision 

 of the Commission in regard to these names was promulgated in Opinion 232 published in 1054 

 (Opin. int. Comm. zool. Nom. 4 : 249-274). By the ruling given in this Opi>iion the name 

 Emesis [Illiger], with the other names concerned, was suppressed under the Plenary Powers 

 for the purposes both of the Law of Priority and of those of the Law of Homonymy. 



In the same Opinion the name Emesis [Illiger], 1807, was placed on the Official Index of 

 Rejected and Invalid Generic Names in Zoology as Name No. 40. 



EMESIS Fabricius, 1807, Mag. f. Insektenk. (Illiger) 6 : 287. Type-species by selection by 

 Westwood, [1851] : Hesperia ovidius Fabricius, 1793, Ent. syst. 3 (1) : 320. 



The taxon represented by the nominal species Hesperia ovidius Fabricius is currently 

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

 species Papilio cereus Linnaeus, 1767 (Syst. Nat. (ed. 12) 1 (2) : Errata), a replacement nominal 

 species established in the stead of Papilio caeneus Linnaeus, 1767 (ibid. 1 (2) : 796), a nominal 

 species, the name of which is invalid (through Linnaeus's own First Reviser choice in 1767 in 

 the " Errata " cited above) as a junior homonym of Papilio caeneus Linnaeus, 1767 (loc. cit. 

 1 (2) : 766), a name applied to a species of the family Pieridae. 



Up till the publication in 1954 of the Commission's Opinion 232 the well-known name 

 Emesis Fabricius, 1807, was invalid as a junior homonym of the slightly older name Emesis 

 [Illiger], 1807. As shown in the discussion on that name the Commission in the above 

 Opinion suppressed the name Emesis [Illiger] for all purposes, thereby validating the name 

 Emesis Fabricius. 



Consequent upon the action described above, the Commission in the same Opinion placed 

 the name Emesis Fabricius, 1807, on the Official List of Generic Names in Zoology as Name 

 No. 660.
