GENERIC NAMES OF BUTTERFLIES 171 



The name Ethelida was published by Westwood in the synonymy of Zeonia Swainson, where 

 it was said to be a manuscript name of Boisduval's. Under Article 11(d) of the present 

 revised Code names published in synonymies do not acquire the status of availability through 

 being so published. The name Ethelida Westwood is therefore invalid. 



At a time when the Code contained no provision relating to the status of a name published in 

 the foregoing fashion it appeared to me to be desirable to dispose of the name Ethelida by 

 selecting as its type-species the nominal species Zeonia heliconides Swainson, 1833, the type- 

 species of the genus Zeonia Swainson, and this I did in 1941. Thus, even if the name Ethelida 

 Westwood had not been published in a synonymy, it would have been invalid as being a 

 junior objective synonym of Zeonia Westwood, 1833.

 original designation : Lycaena ethion Westwood, | Dec. 1851], in Doubleday, Gen. ditirn. Lep. 

 (2) : pi. 76, fig. 3 [text (loc. cit. (2) : 490) published in April 1852]. 



This generic name is invalid, as it is a junior objective synonym of Discolampa Toxopeus, 

 1929.

 (replacement names) of Article 67 : Mycalesis (?) himachala Moore, 1857, in Horsfield &

Moore introduced the name Ethope as a replacement for Theope Moore, 1857, which is 

 invalid under the Law of Homonymy.

EUCALIA Felder (C), 1861, Nova Acta Leop. Carol. 28 (No. 3) : 25. Type-species by 

 selection by Hemming (1939, Proc. R. ent. Soc. Lond. (B) 8 : 134) : Diadema anthedon 

 Doubleday, 1845, Ann. Mag. nat. Hist. 16 : 181. 



The name Diadema anthedon is commonly treated subjectively as a senior subjective syno- 

 nym of Papilio dabius Palisot de Beauvois, [1813-1820], the name of the type-species of the 

 genus Euralia Westwood, [1850]. On the basis of this synonymy the name Encalia Felder — 

 which appears to have been a genuine new name and not an incorrect subsequent spelling of 

 Euralia Westwood — would be treated as a junior subjective synonym of Euralia -if it were 

 not for the fact that the taxon represented by the foregoing nominal species is subjectively 

 treated on taxonomic grounds as being the same as that represented by the nominal species 

 Papilio pipleis Linnaeus, 1758 (itself subjectively identified with Papilio pandarus Linnaeus 

 1758), the type-species of the older-established nominal genus Hypolimvas Hiibner, [1819].

 [ J 775]. Uitl. Kapellen 1 (4) : 64, pi. 40, figs C, D. 



The name Eucharia Boisduval is invalid, as being a junior homonym of Eucharia Hiibner, 

 [1820] (Verz. bekamit. Schmett. (12) : 181) and also of Eucharia Koch, 1835 (in Panzer, Ins. 

 germ. (134) : pi. 8).

This nominal genus was for a long time a cause of difficulty, owing to the fact that the 

 included nominal species selected as the type-species by Butler in 1870 (Cistula ent. 1 : 53) 

 was misidentified by Hiibner when he established this genus. The entry for this species made
