TRAPEZITES Hiibner, [1819], Verz. bekannt. Schmett. (7) : 112. Type-species by subse- 

 quent monotypy under Article 69(a) (ii) : Trapezites symmomus Hiibner, [1823], Zutr. 

 z. Samml. exot. Schmett. 2 : 10, pi. [40], figs 225, 226. 



Hiibner gave a brief diagnosis when he established this genus in the \'crzeicliniss and the 

 name therefore ranks from that work. He did not cite any established nominal species as 

 belonging to this genus, listing only the name of a then unpublished spec :ies [symmomus 

 Hiibner). Hiibner himself was the first subsequent author to deal with this genus, citing it 

 in 1823 in the Zutrdge and placing in it only the nominal species Trapezites symmomus then 

 described (and figured) for the first time. Under Artie le 6o(a)(iii) that species is therefore the 

 type-species by subsequent monotypy. 



TREPSICHROIS Hiibner, 1816, Verz. bekannt. Schmett. (1) : 16. Type-species by selection 

 by Moore (1883, Proc. zool. Soc. Lond. 1883 : 286) : Papilio claudia Fabricius, 1777, Gen. 

 Ins. : 263 [a taxon bearing a name which is invalid, as it is a junior homonym of Papilio 

 claudia Cramer, [1775], Uitl. Kapellen 1 (6) : 109, pi. 69, tigs E, F]. 



The invalid name [Papilio claudia Fabricius) of the type-species lias not been provided with 

 an objective replacement, this not being considered to be necessary in view of the fact that 

 the taxon represented by the foregoing nominal species is — and for long has been — treated 

 subjectively on taxonomic grounds as being the same as that represented by the nominal 

 species Papilio mulciber Cramer, [1777] (Uitl. Kapellen 2 (11) : 45, pi. 127, figs C, D). 



Scudder in 1875 (Proc. amer. Acad. Arts Sci., Boston 10 : 286) attempted to select a type- 

 species, following his usual practice of combining the specific nomenclature employed by the 

 author (Hiibner) of the generic name with that employed by Kirby in 1871 in his Syn. Cat. 

 diurn. lep. If he had cited one only of the names listed by Hiibner with the name cited by 

 Kirby (in 1871) for the same taxon, his action would have constituted a valid type-selection 

 under Article 69(a) (iv) of the Code. Unfortunately, Kirby subjectively identified three of the 

 nominal species placed in this genus by Hiibner and in this was followed by Scudder who thus 

 failed definitely to select as the type-species one, and one only, of the nominal species placed 

 by Hiibner in this genus. 



The first author validly to select a type-species for the genus Trepsichrois was Moore when 

 he selected Papilio claudia Fabricius, 1777. Hiibner did not recognize this as representing a 

 taxonomically valid species, citing its name only as a junior synonym of Papilio basilissa 

 Cramer, [1780], the first of the five nominal species cited by Hiibner in the above genus. It 

 was formerly a matter of doubt whether a nominal species is eligible for selection as the type- 

 species of a genus if its name was cited by the original author of the generic name only as a
