concerned is the older and should therefore be used in preference to the other. Luckily, this 

 difficulty has now been disposed of by the Commission in its Opinion 516 (1958, Opin. 

 int. Comm. zool. Nom. 19 : 1-44) in which it laid down the relative precedence to be 

 accorded to certain works, including those by Fabricius and Cramer, published in 1775. In 

 this Opinion the Commission ruled under its Plenary Powers that the Syst. Ent. of Fabricius 

 was to take precedence before the portions of Cramer's Uitl. Kapellen published in 1775. 

 Under this ruling therefore the name Papilio acheronta Fabricius is confirmed in the position 

 normally attributed to it and becomes the oldest name subjectively applicable to the species 

 here in question. 



COELIADES Hiibner, 1818, Zntr. z. Samml. exot. Schmett. 1 : 31. Type-species by selection by 

 Hemming (1935, Trans. R. ent. Soc. Lond. 83 : 436) : Papilio forestan Stoll, [1782], in Cramer 

 Uitl. Kapellen 4 (33) : 210, pi. 391, figs E, F. 



The name Coeliades was published by Hiibner in 181 8 in the first volume of the Zutrage 

 and in 1819 in the Verz. bekannt. Schmett. ((7) : 106). Scudder in 1875 (Proc. amer. Acad. 

 Arts Sci., Boston 10 : 145) overlooked the publication of the name Coeliades in the Zutrage 

 and fell into the error of treating this name as having been first published in the Verzeichniss. 

 On this basis he selected as the type-species of this genus the nominal species Papilio dubius 

 Stoll, [1781]. This choice was unfortunate because this species was not included in the genus 

 Coeliades when first established by Hiibner in the Zutrage. Scudder's action was therefore 

 invalid. This genus remained without a type-species until Papilio forestan was selected as 

 such by myself in 1935. 



CO ELITES Westwood, [1850], in Doubleday, Gen. diurn. Lep. (2) : pi. 66, fig. 2. Type-species 

 by monotypy : Coelitis nothis Westwood, [1850], in Doubleday, ibid. (2) : pi. 66, fig. 2. 



Some authors have erroneously treated this generic name as having been first published by 

 Westwood in the text of the above work ((2) : 367) where that author placed in Coelites two 

 nominal species {Coelites nothis and another). In fact, however, the text was not published 

 until April 1851, whereas plate 66 was published in December 1850. No practical incon- 

 venience has however arisen from this mistake, because Butler, the first author to select a 

 type-species for this genus on the basis of the name having been published first in the text, so 

 selected (1868, Ent. mon. Mag. 4 : 195) Coelites nothis which, as explained above, had in fact 

 been the type-species by monotypy ever since the first appearance in December 1850 of the 

 name Coelites on the legend to plate 66. 



COENONYMPHA Hiibner, [1819], Verz. bekannt. Schmett. (5) : 65. Type-species by selection 

 by Butler (1868, Ent. mon. Mag. 4 : 194) : Papilio geticus Esper, [1793], Die Schmett., 

 Suppl. Band 1 Abschn. Tagschmett. : 51, pi. 102, fig. 2 $. 



When establishing the genus Coenympha, Hiibner placed at the head of the list of included 

 species his own new nominal species Coenonymphia oedipe, which in accordance with his cus- 

 tom in the Verzeichniss was based entirely upon bibliographical references to plates or portions 

 of text published by previous authors. The second of the three specific names so cited was 

 geticus Esper. Under Article 69(a) (i) the citation of a specific name in the synonymy of 

 one of the originally included species given by the author when establishing a genus confers 

 upon the species bearing the specific name so cited the status of an originally included species. 

 Butler's selection of Papilio geticus Esper as the type-species of the genus Coenonympha 

 Hiibner was therefore perfectly in order. 



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

 tively on taxonomic grounds either as a subspecies of, or as the same as, the taxon represented 

 by the nominal species Papilio oedippus Fabricius, 1787 {Mantissa Ins. 2 : 31).
