Esper, [1780], Die Schmett. 1 (Bd 2) : Forts. Tagschmett. : 25. The taxon represented by 

 the invalid name Papilio philoxenus Gray is currently treated subjectively on taxonomic 

 grounds as the same as that represented by the nominal taxon Papilio philoxenus letincius 

 Fruhstorfer, 1908, Ent. Z. 22 (18) : 72. Further, the taxon represented by the foregoing 

 nominal taxa is currently considered subjectively on taxonomic grounds as being a subspecies 

 of the taxon represented by the nominal species Papilio polyeuctes Doubleday, 1842 (Zool. 

 Miscell. (Gray) (5) : 74).

The taxon represented by the nominal species Papilio julettus Stoll is currently treated 

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

 established nominal species Papilio procas Cramer, [1777] {Uitl. Kapellen 2 (15) : 127, pi. 179, 

 fig. D). 



CACYREUS Butler, [1898], Proc. zool. Soc. Lond. 1897 (4) : 845. Type-species by original 

 designation : Papilio lingeus Stoll, [1782], in Cramer, Uitl. Kapellen 4 (32) : 176, pi. 379, 

 figs F, G. 



Butler introduced the name Cacyreus as a replacement name for Hyreus Hiibner, [1819], 

 which is invalid under the Law of Homonymy. At the time of the publication of Butler's 

 paper the genus Hyreus Hiibner was without a type-species; accordingly, Butler was fully 

 entitled to take the course which he did, namely to designate one of the nominal species 

 originally included in Hyreus to be the type-species of his replacement genus Cacyreus, 

 thereby — under Section (i) of Article 67 — designating the same species to be also the type- 

 species of Hyreus Hiibner. 



CADUGA Moore, [June] 1882, Proc. zool. Soc. Lond. 1882 (1) : 235. Type-species by mono- 

 typy : Danais tytia Gray, 1846, Descr. lepid. Ins. Nepal : 9, pi. 9, fig. 2. 



CADUGA Moore, 1883, Proc. zool. Soc. Lond. 1883 : 249. Type-species by original designation : 

 Danais tytia Gray, 1846. 



Moore published the name Caduga as a new name, despite the fact that in the previous year 

 he had (as shown above) established a genus with the same name and the same type-species. 

 This can only have been due to some inadvertence, the only difference between the two 

 publications of this name being that on the first occasion the type-species was determined by 

 monotypy and on the second by original designation. The name Caduga as of 1883 is invalid, 

 first as a junior homonym of the same name as of 1882, and second as a junior objective 

 synonym of that name.
