GENERIC NAMES OF BUTTERFLIES 43 



depends on the choice made by the First Reviser. I n this case, the First Reviser was Edwards 

 who (as Mr. Cyril F. dos Fassos has kindly pointed out in litt.) in 1872 (Svn. .V. Amer. Butts : 

 44) identified Hesperia logon with Hesperia delaware and sank the specific name logan as a 

 junior subjective synonym of the name delaware. The same course was taken by Godman & 

 Salvin in 1900 (Biol, centr .-amer . , Lep. Rhop. 2 : 490). It should be added that under the 

 idea that in cases of this kind relative precedence should be determined in accordance with the 

 principle of page precedence Barnes & McDunnough (Contrib. not. Hist Lepid. N. Amer. 3 (2) : 

 132) gave preference to the name logan over the name delaware by reason of its having been 

 published one page earlier than delaware (on page 18 as compared with page 19). This 

 contention was already invalid at the time of the publication of Barnes & McDunnough's 

 paper, for Article 28 of the Code then in force provided that a ( ase such as this was governed 

 by the First Reviser principle, and this is even more explicitly prescribed in the revised text 

 of the Code (Article 24(a)) now in force. 



ANCH1PHLEBIA Butler, July 1868, Cat. dutrn. Lep. Satyndae Brit Mus : 106. Type- 

 species by original designation : Antirrhea archaea Hiibner, [1822 , Samml. exot. Schmett 

 2 : pi. [81]. 



Anchiphlebia was published on the above occasion as the name of a new genus. It is 

 therefore not to be treated as an Incorrect Subsequent Spelling of, or as an Unjustified 

 Emendation of the slightly earlier name Anchyphlebia Butler, February 1868 (see below). 

 Further, under the " One-Letter-Difl " Rule (Article 56(a)} the names Anchiphlebia 



Bulter and Anchyphlebia Butler are not homonyms of one another. The name Anchiphlebia 

 Butler, July 1868, is however, invalid as a junior objet tive synonym oi Anchyphlebia Butler, 

 February 1868. Both these names are in addition invalid as junior objective synonyms of 

 Antirrhea Hiibner, ji>

 Scudder (1875, Proc. amer. Acad. Arts Set., Boston 10 : 112) : Ancyluris pyrete Hiibner, 

 [1819], ibid. (2) : I}, (a nominal taxon objectively identical with the nominal species Papilio 

 meliboeus Fabricius, 1777 (den. Ins. : 271) through the lectotype selection made by Hemming 

 (1964, Annot. lep. (3) : 101). 



The nominal species Ancyluris pyrete was established by Hiibner on the basis of two 

 bibliographical references, the first to Papilio pyretus Cramer, [1777] (I'itl. Kapellen 2 (12) : 

 76, pi. 144, figs. A, \>\, the second, to Papilio melibocits Fabricius, 1777. Prior to 1958 there 

 existed no means for determining the relative precedence to be accorded to names published 

 in the same year by Fabricius and Cramer respectively. In 1958 however the Commission 

 promulgated its Opinion 516 (Opin. int. Comm. zool. Norn. 19 : 1-44), in which, while 

 dealing with this situation in relation to the year 1775 it gave a Ruling that precedence 

 be accorded to Fabrician names over those published by Cramer. The situation in this 

 matter obtaining in relation to the year 1777 is exactly similar to that in 1775, and accordingly 

 the name Papilio meliboeus Fabricius is to be treated as having precedence over Papilio 

 pyretus Cramer published in the same year. By the lectotype-selection made by Hemming in
