194 FRANCIS HEMMING 



Aecas Hemming. However, under a provision adopted by the Copenhagen Congress in 1953 

 and now embodied in the revised Code in Article 56 (a) a one-letter difference in spelling serves 

 to prevent any two generic names from being treated as homonyms of one another. Under 

 this provision, therefore, the name Flaccilla Godman is not a homonym of Flacilla Koken, 

 but is an available name. 

 FLOS Doherty, 1889, /. asiat. Soc. Bengal, Pt II, 58 (4) : 412. Type-species by original designa- 

 tion : Papilio apidanus Cramer, [1777], Uitl. Kapellen 2 (12) : 63, pi. 137, figs F, G. 



Following an erroneous type-selection made by Scudder in 1875, Papilio apidanus, the 

 type-species of the present genus, was incorrectly treated for many years as being the type- 

 species of the genus Amblypodia Horsfield, [1829]. The subsequent history of the name 

 Amblypodia Horsfield and the associated names Arhopala Boisduval and Horsfieldia Riley has 

 been explained in detail in the note given under the name Amblypodia.

FRITILLA Capronnier, 1874, Ann. Soc. ent. Belg. 17 : 20. 



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

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

 species — Fritilla meleagris — which was a manuscript species of Boisduval's. Capronnier 

 gave no description for this nominal species, furnishing only a few brief observations on the 

 habits of the species which are quite insufficient to permit the identification of this nominal 

 species. The name of this nominal species is thus a nomen nudum; in consequence, so also 

 is the generic name Fritilla as published by Capronnier, in view of the fact that (as explained 

 above) he gave no generic diagnosis for this taxon. The name Fritilla Capronnier (like the 

 name Dyndirus Capronnier published in the same paper) thus possesses no status in zoological 

 nomenclature. It is cited here only for the purposes of record, because it has found its way 

 into various lists of names that have been published. 



FULDA Evans, 1937, Gat. African Hesp. Brit. Mus. : 86. Type-species by original designation : 

 Hesperia coroller Boisduval, 1833, Nouv. Ann. Mus. Hist, nat., Paris 2 (2) : 214, pi. 9, fig. 8 

 (separate as Faune ent. Madagascar, Lep. : 66, pi. 9, fig. 8) . 



FULVIA Higgins, [1959], Lepid. News 12 (5/6) : 162. Type-species by original designation : 

 Melitaea fasciata Hoppfer, 1874, Stett. ent. Ztg 35 : 349. 



The name Fulvia Higgins is invalid, as it is a junior homonym of Fulvia Gray, 1853 [Ann. 

 Mag. nat. Hist. (2) 11 : 40) and also of Fulvia Adams, 1957 {Gen. Pec. Moll. 2 : 547). It has 

 been replaced by the name Higginsius Hemming, 1964, Annot. lep. (4) : 139. 



FUTURONERVA Bryk, 1928, Ent. Z. 42 : 50. Type-species by original designation : 

 Futuronerva absurda Bryk, 1928, ibid. 42 : 50. 



The name Futuronerva and Futuronerva absurda, together with the associated family name 

 Futuronervidae, represent one of the most extraordinary episodes in the nomenclature of 

 the butterflies, for, as observed by Klots in 1933 {Ent. amer., Brooklyn (n.s.) 12 (3) : 153), 

 the type-species of the nominal species Futuronervea absurda, the foundation on which the 

 whole of this ridiculous systematic edifice rests, is no more than a teratological female specimen 

 with deformed venation belonging to the common Palaearctic Pierid Papilio crataegi Linn- 

 aeus, 1758, the type-species of the genus Aporia Hiibner. [1819].
