TRITONIA Geyer, [1832], in Hiibner, Zutr. z. Samml. exot. Schmett. 4 : 25. Type-species by 

 selection by Scudder (1875, Proc. amer. Acad. Arts Sci., Boston 10 : 286) : Tritonia eupompe 

 Geyer, [1932], ibid. 4 : 25, pi. [121], figs 699, 700. 



Scudder erroneously supposed that the above was the only species included in this genus 

 by Geyer and it was on this basis that he stated that it was the type-species. This mis- 

 understanding on Scudder's part does not however detract from the efficacy of his action 

 as a type-selection (Article 69(a) (hi)). 



The name Tritonia Geyer is invalid under the Law of Homonymy, it being a junior homonym 

 (a) of Tritonia Cuvier, 1798 (Tabl. ettm. : 387), (b) of Tritonia Meigen, 1800 (Nouv. Class. 

 Mouches a deux Ailes : 33), and (c) of Tritonia Turton, 1825 (Zool. J. 2 (7) : 365). It has been 

 replaced by the name Epityches Ferreira d'Almeida, 1938.

Kirby attributed this name to Barbut who, he erroneously believed, had published it as a 

 generic name in binominal nomenclature. Actually, Kirby himself on this occasion was the 

 first author validly to publish Tros as a generic name.

TUMEREPEDES Bethune-Baker, 1913, Ann. Mag. nat. Hist. (8) 11 : 564. Type-species by 

 original designation : Tumerepedes flava Bethune-Baker, 1913, ibid. (8) 11 : 565. 



This is a badly formed name, because the concluding portion (" -pedes ") consists of a 

 noun in the nominative plural. It is not however invalidated on that account, for Article 

 11(f), which provides that a generic name must be a noun in the nominative singular, includes 

 the qualifying words "or be treated as such ". While the present generic name bears a 

 termination in the nominative plural, the name itself was treated by Bethune-Baker as a 

 noun in the nominative singular. In spite of its defective form, the name Tumerepedes is 

 therefore acceptable under the Code. 



TUMEREPES Aurivillius, [1921], in Seitz, Grossschmett. Erde 13 : 347 (an Unjustified Emenda- 

 tion of Tumerepedes Bethune-Baker, 1913). 



Aurivillius rightly criticized the name Tumerepedes Bethune-Baker owing to the fact that 

 its termination was in the plural instead of in the singular, but (as explained above) he was 

 not justified in emending that name on this account.
