GENERIC NAMES OF BUTTERFLIES 153 



by Trimen in the form " I)' Urbania ". Under the current revised Code (Article 27) the use of 

 an apostrophe in a zoological name is not permissible. In the present case the correct form is 

 " Durbania ". 



DURBANIELLA van Son, 1959, Novos Taxa ent. No. 16 : 10. Type-species by original 

 designation : Durbania clarki van Son, 1941, /. ent. Soc. S. Afr. 4 : 183. 



DURBANIOPSIS van Son, 1959, Novos Taxa ent. No. 16 : 12. Type-species by original 

 designation : Durbania saga Trimen, 1883, Trans, ent. Soc. Lond. 1883 : 354. 



DYCTIS Boisduval, 1832, in d'Urville, Voy. " Astrolabe ", Faun. ent. 1 (Lep.) : 138. Type- 

 species by monotypy : Dyctis agondas Boisduval, 1832, in d'Urville, ibul., Faun. ent. 

 1 (Lep.) : 138, pi. 3, fig. 5. 



DYGORIS Fox, 1945, Amer. Mus. Novit. No. 1295 : 10. Type-species by original designation : 

 Ithomia dircenna Felder (C.) & Felder (R.), [1865], Reise Fregatte " Novara ", Lep. Rhop. 

 (2) : pi. 45, figs 4, 5 ; id., [1867], ibid., Lep. Rhop. (3) : 360. 



DYMASIA Higgins, i960. Trans. R. ent. Soc. Loud. 112 : 454. Type-species by original 

 designation : Melitaea dymas Edwards, 1877, Canad. Ent. 9 : 100. 



DYNAMINE Iliibner, [1819], Yerz. bekannt. Schmett. (3) : 41. Type-species by selection by 

 Scudder (1875, Proc. amer. Acad. Arts Sci , Boston 10 : 160) : Papilio mylitta Cramer, 

 [1799], Uitl. Kapellen 3 (22) : 107, pi. 253, figs 1), E. 



DYNASTOR Doubleday, [1849], Gen. diurn. Lep. (2) : pi. 58, fig. 2. Type-species by mono- 

 typy : Dynastor napoleon Doubleday, [1849], ibid. (2) : pi. 58, fig. 2. 



In the text relating to this generic name, which was not published until 1851 [ibid. (2) : 

 346) and for which Westwood was responsible, Dynastor napoleon was again the only species 

 cited as belonging to this genus. 



DYNDIRUS Capronnier, 1874, Ann. Soc. ent. Belg. 17 : ^z. 



Capronnier's intention was to apply this generic name to some generic taxon in the family 

 S.ityridae. He gave no generic diagnosis and placed in this genus only a single nominal 

 species — Dyndirus nerces — which was a manuscript species of Boisduval 's. Capronnier gave 

 no description for this nominal species which therefore, as published by him was no more than 

 a nomen nudum. So also was the generic name Dyndirus, as published by Capronnier, for, 

 as shown above, that author gave no diagnosis for this genus and cited under it only one 

 species-name which was also a nomen nudum. Accordingly, the name Dyndirus Capronnier 

 possesses no status in zoological nomenclature. It is cited here only for purposes of record, 

 because it has found its way into various lists of names that have been published. 



DYNOTHEA Reakirt, [1866], Proc. ent. Soc. Philad. 5 : 222. Type-species by selection by 

 Scudder (Feb. 1875, Hull. Buffalo Soc. not. Sci. 2 : 246) : Papilio lycaste Fabricius, 1793, 

 Ent. syst. 3 (1) : 161. 



Later in 1875 (Proc. amer. Acad. Arts Sci., Boston 10 : 160) Scudder made a second type- 

 selection for this genus, again selecting Papilio lycaste as type-species. 



DYSCOPHELLUS Godman & Salvin, [1893], Biol, centr.-amer., Lep. Rhop. 2 : 319. Type- 

 species through Section (i) (replacement names) of Article 67 : Papilio sebaldus Stoll, 

 [1781], in Cramer, Uitl. Kapellen 4 (29) : 101, pi. 342, figs A, B. 



The name Dyscophellus was introduced by Godman & Salvin to replace the name Dyscophus 

 Burmeister, 1878, which is invalid under the Law of Homonymy. 



DYSCOPHUS Burmeister, 1878, Descr. phys. Rip. Argentine 5 (Lep.) (1) : 291. Type-species 

 by original designation : Papilio sebaldus Stoll, [1781]. 



The name Dyscophus Burmeister is invalid, it being a junior homonym of Dyscophus 

 Grandidier, 1872 (Ann. Sci. nat. Paris, Zool. (3) 15 (20) : 10) and also of Dyscophus Saussure, 

 1874 (Miss. sci. Mixique Amir, centr., Rech. Zool. 6 : 430, 438). As shown above, it has been 

 replaced by the name Dyscophellus Godman & Salvin.
