[1891], which is invalid under the Law of Homonymy. The replacement name Iridopsis 

 is however itself invalid as a junior homonym of Iridopsis Warren, 1894 (Novit. zool. 1 : 436). 

 Later, as shown above, Aurivillius introduced a second replacement name, Iridana Aurivillius, 

 [192 1], and, as this is an available name, it became the nomenclatorially valid name for this 

 genus. 



IRIS Staudinger, [1891], Iris 4 (1) : 141. Type-species by monotypy : Iris incredibilis 

 Staudinger, [1891], ibid. 4 (1) : 141. 



The name Iris Staudinger is invalid, as it is a junior homonym of Iris Saussure, 1872 {Mitt, 

 schweiz. ent. Ges. 3 : 56). As shown above, the name Iris Staudinger has been twice replaced ; 

 the first replacement name, Iridopsis Avrivillius, [1898], was itself invalid under the Law of 

 Homonymy, but the second, Iridana Aurivillius, [1921], is an available name and is thus the 

 nomenclatorially valid name for this genus.

ISAMIA Moore, [1880], hep. Ceylon 1 (1) : 10. Type-species by original designation : Papilio 

 superbus Herbst, 1793, in Jablonsky, Natursyst. Ins., Schmett. 6 : 14, pi. 119, fig. 3 3* ; 

 pi. 120, figs 2, 3 ?. 



The taxon represented by the nominal species Papilio superbus Herbst is currently treated 

 subjectively on taxonomic grounds as being the same as that represented by the older-estab- 

 lished nominal species Papilio midamus Linnaeus, 1758 (Syst. Nat. (ed. 10) 1 : 470). 



ISAMIOPSIS Moore, 1888, Descr. new ind. Lep. Coll. Atkinson (3) : 284. Type-species by 

 original designation : Papilio telearchus Hewitson, 1852, Trans, ent. Soc. Lond. (2) 2 : 22, 

 pi. 6, fig. 3. 



The taxon represented by the nominal species Papilio telearchus Hewitson is currently 

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

 older-established nominal species Papilio paradoxa Zinken, [1831] (Nova Acta Leop. 

 Carol. 15 (1) : 162, pi. 15, figs 9, 10). 



The name Isamiopsis Moore is invalid, as it is a junior objective synonym of the name 

 Euploeopsis de Niceville, 1888. 



ISAPIS Doubleday, 1847, List Spec. lep. Ins. Brit. Mus. 2 : 18. Type-species by monotypy :

ISM A Distant, 1886, Rhop. malay. : 369, 386. Type-species by original designation : Isma

ISM EN A Mabille, 1891, Bull. C. R. ent. Soc. Belg. 35 : lxxviii (an Incorrect Subsequent Spelling

ISMENE Swainson, 1820, Zool Illustr. (1) 1 (3) : pi. 16. Type-species by monotypy : Ismene 

 oedipodia Swainson, 1820, ibid. (1) 1 (3) : pi. 16. 



The name Ismene Swainson is invalid, as it is a junior homonym of Ismene Savigny, 1816 

 (Mem. Anim. sans Vertebr. 1 : 34). 



ISMENE Nickerl, 1846, Stett. ent. Ztg 7 : 207. Type-species by monotypy : Ismene helios 

 Nickerl, 1846, ibid., Stettin 7 : 208, pi. [3], figs A, B 6\ C, D ?. 



The name Ismene Nickerl is invalid as a junior homonym of Ismene Savigny, 1816, and 

 Ismene Swainson, 1820, the two names discussed above in the immediately preceding note. 

 The name Ismene Nickerl has been replaced by the name Hypermnestra Menetries, 1848. 



ISODEMA Felder (C.) & Felder (R.), 1863, Wien. ent. Monats. 7 : 109 nota. Type-species 

 through Section (i) (replacement names) of Article 67 : Paraplesia adelma Felder (C.) & 

 Felder (R.), 1862, ibid. 6 : 26. 



The name Isodema was introduced by C. & R. Felder as a replacement for the name Para- 

 plesia which they had published in the previous year (1962, Wien ent. Monats. 6 : 26) but 

 which they now thought was invalid under the Law of Homonymy through having already 

 been used by Herrich-Schaeffer for a genus of moths. In so thinking, they were mistaken, for
