GENERIC NAMES OF BUTTERFLIES 25 



a twofold misapprehension and that in this he was followed both by Hiibner and by Scudder. 

 First, Cramer's " eurita " was a composite, the specimens figured by him as figs A and B 

 belonging to different species, neither of which belongs to the genus always known as Actinote ; 

 each of these is however an Acraeid, both being referable to the genus Bematistes Hemming, 

 1935 (formerly widely but incorrectly known by the name Planema Doubleday, [1848]). 

 Second, Cramer did not look upon himself as the author of the name eitryta, attributing it to 

 Linnaeus, i.e. identifying it with Papilio eurytus Linnaeus, 1758 (Sysl. Nat. (ed. 10) 1 : 487). 

 This latter nominal species is currently considered subjectively on taxonomic grounds to 

 represent the same taxon as that represented by the type-species of the genus Pseudacraea 

 Westwood, [1850]. This genus is only distantly related to the Acraeids, but its species are 

 mimics of species of the genus Acraea Fabricius. 



Under the Code an author erecting a new genus or selecting the type-species of a genus is to 

 be treated as having correctly identified the taxon in question. If this principle had been 

 applied in the present case, the confusion involved in nomenclature would have been very 

 serious : Actinote, hitherto always used for the Acraeid genus containing Papilio thalia Lin- 

 naeus, would have to be transferred to the totally different Acraeid-mimicking Nymphalid 

 genus always known by the name Pseudacraea. This case was submitted to the International 

 Commission on Zoological Nomenclature by myself in 1938 with a request that existing 

 nomenclatorial practice should be protected by the use of Plenary Powers for the purpose of 

 designating Papilio thalia Linnaeus as the type-species of the genus Actinote. As already 

 noted, this proposal was approved by the Commission in 1954. Finally, in Opinion 214 the 

 name Actinote Hiibner with Papilio thalia Linnaeus as type-species was placed on the Official 

 List of Generic Names in Zoology as Name No. 648.

 (replacement names) of Article 67 : Limnas cinaron Felder (C.) & Felder (R.), 1861, Wien. 

 ent. Monats. 5 : 101. 



Kirby introduced the name Aculhua as a substitute name for the name Dryas Felder (C.) & 

 Felder (R.), [1865], which is invalid under the Law of Homonymy. Kirby did not specify a 

 type-species for Aculhua but, as that nominal genus was proposed as a substitute for Dryas 

 Felder & Felder, it is automatically Limnas cinaron Felder & Felder, the type-species (by 

 monotypy) of the genus replaced.

The taxon represented by the nominal species Pandemos nymphidioides Butler has been 

 treated by some authors (e.g. Stichel, 1931, in Strand's Lep. Cat. 44 : 721) as representing a 

 subspecies of the taxon represented by the nominal species Nymphidium ethelinda Hewitson, 

 1870 {Ent. mon. Mag. 7:6).
