that Burmeister had placed only one species in this genus and therefore that the species in 

 question, namely Goniuris tmolis was automatically the type-species by monotypy. Not- 

 withstanding this misunderstanding on Evans' part, his explicit statement that the above was 

 the type-species ranks as a valid type-selection under Article 69(a) (iii) of the Code. 



The appearance in the literature of this long-forgotten name would have justified the sub- 

 mission to the Commission of a request for it to be rejected as a nomen oblitum, if its acceptance 

 would have displaced some name in current use. Fortunately, this is not the case, Goniuris 

 tmolis, the type-species of Eridamus , being currently considered on taxonomic grounds to be 

 congeneric with Papilio tityrus Fabricius, 1775, the type-species of Epargyreus Hiibner, [1819]. 

 By this lucky chance the unwanted name Eridamus Burmeister disappears as a junior sub- 

 jective synonym of Epargyreus Hiibner.

ERIOCOLIAS Watson, 1895, Entomologist 28 : 167. Type-species by original designation : 

 Papilio edusa Fabricius, 1787, Mantissa Ins. 2 : 23. 



The name Papilio edusa Fabricius, 1787, is invalid, because it is a junior homonym of the 

 name Papilio edusa Fabricius, 1777 {Gen. Ins. : 255). 



The taxon represented by the nominal species Papilio edusa Fabricius, 1787, is currently 

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

 nominal species Papilio croceus Fourcroy, 1785 (Ent. paris. : 250), which is considered to be 

 the oldest available name applicable to this species.

Guerin's text relating to the type-species was not published until [1838], but in the mean- 

 while a description of " Anthocharis chilensis " [sic] had been published by Boisduval ([1836], 

 (Roret's Suite a Buffon), Hist. nat. Ins., Consid. gen. 1 (Lepid.) : 566). Guerin's own 

 description of this species, again under the name Pieris chiliensis, appeared in the same volume 

 as that in which his plate showing this species had been issued ; the page concerned bore the 

 number " 174 ", but, as reference to the volume shows, this was a misprint for " 274 ".
