copy in the British Museum of the volume in which it was published, stating that publication 

 took place on 25th February 1893. Thus, the name Pteroxys Hampson has about three 

 months' priority over the name Pteroxys Watson, which is therefore invalid under the Law 

 of Homonymy. It has been replaced by the name Orthophoetns Watson, 1895.

 sequent Spelling of Pterourus Scopoli, 1777). 



PTERYGOSPIDEA Wallengren, 1857, K. svenska VetenskAkad. Handl., Stockholm (n.f.) 2 (1) 

 (No. 4) : 53. Type-species by selection by Scudder (1875, Proc. amer. Acad. Arts Sci., 

 Boston 10 : 260) : Papilio ophion Stoll, [1790], Aanhangs. Werk. Uitl. Kapellen Pieter 

 Cramer : 127, pi. 26, figs 4, 4c. 



The name Pterygospidea was published by Wallengren as a new name on two occasions, 

 first in 1857 (as shown above) and second, in 1858 (Ofvers. VetenskAkad. Fork., Stockh. 15 : 



83)- 



The taxon represented by Papilio ophion Stoll is currently treated subjectively on taxonomic 

 grounds as being the same as that represented by the older-established nominal species 

 Papilio flesus Fabricius, 1781 [Spec. Ins. 2 : 135).

PTYCHOPTERYX Wallengren, 1857, K. svenska VetenskAkad. Handl., Stockholm (n.f.) 2 (Pt 1) 

 (No. 4) : 17. Type-species by monotypy : Ptychopteryx bohemani Wallengren, 1857, ibid. 

 (n.f.) 2 (Pt 1) (No. 4) : 18. 



The taxon represented by the nominal species PtycJiopleryx bohemani Wallengren is 

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

 by the older-established nominal species Teracolas snbfasciatus Swainson, [1833] (Zool. 

 Illustr. (2) 3 : pi. 115). 



The name Ptychopteryx Wallengren is invalid, as being a junior homonym of Ptychopteryx 

 Leach, 1817 (in Brewster's Edinb. Ency. 12 (1) : 155).

 (Purlisa) giganteus Distant, 1881, ibid. 17 : 245. 



By some strange inadvertence Distant republished the name Purlisa as the name of a new 

 genus (" gen. nov.") in 1885 (Rhop. malayana : 234, 249), this being all the more strange in 

 that he clearly indicated that he was aware both that he had himself published it in 1881 

 and also that it had subsequently been used by Waterhouse in 1882 (Aid I dent. Ins. 1 : pi. 46). 



PUTLIA Moore, [1892], Lep. ind. 1 (12) : 287. Type-species through Section (i) (replacement 

 names) of Article 67 : Zophoessa baladeva Moore, [1866], Proc. zool. Soc. Lond. 1865 (3) : 769, 

 pi. 41, fig. 5. 



Moore introduced the name Putlia as a replacement for the name Charma Doherty, 1886, 

 which he considered was a homonym of the older name Charmus Karsch, 1879 (Mitt, miinchn. 

 ent. Ver. 3 : 101, 104) and therefore invalid. At the time when Moore took this action the 

 Code had not been adopted and even after its introduction there was still no clear provision 

 as to the criteria to be adopted in determining whether any two generic names should be 

 treated as homonyms of one another ; it was not until the publication in 1961 of the present 

 revised text of the Code that a rule was introduced (Article 56(a)) that names differing in 

 spelling by even a single letter are not to be treated as homonyms of one another. According-
