COLAENIS Hiibner, [1819], Verz. bekannt. Schmett. (2) : 32. Type-species by selection by 

 Scudder (1875, Proc. amer. Acad. Arts Sci., Boston 10 : 146) : Papilio Julia Fabricius, 1775,

This name is invalid, as it is a junior objective synomni i>t Dryas Hiibner, [1807]. 



COLIAS Fabricius, 1807, Mag. f. Insektenk. (Uliger) 6 : 284. Type-species by designation by 

 the Commission under the Plenary Powers in Opinion 14O : Papilio hyale Linnaeus, 1758, 

 Syst. Nat. (ed. 10) 1 : 469. 



The first author to select one of the originally included species to be the type-species of 

 Colias Fabricius was Latreille who in 1810 (Consid .'• limn. Crust. Arachn. Ins. : 440) 

 selected Papilio rhamni Linnaeus, 1758 (Syst. Nat. (ed. 10) 1 : 470). The next author to 

 select a type-species for this genus was Swainson (1820, Zool. Illnstr. (1) 1 : pi. 5) who so 

 selected Papilio eubule Linnaeus, 1767 (Syst. Nat. (ed. 12) 1 (2) : 764), but that selection was 

 automatically invalid, as the species selected was not one of those cited by Fabri< ius when he 

 established the genus Colias in 1807. In 1829 (Brit. Entom. 6 : pi, 242) Curtis selected 

 Papilio hyale Linnaeus, 1758 (Syst. Nat. (ed. 10) 1 : 469) to be the type-species of this genus. 

 Later, Butler (1870, Cistula ent. 1 : 43) selected ,1^ tin- t \ pc-species Papilio palaeno Linnaeus, 

 1761 (Faun. svec. (ed. 2) : 272), a nominal species both then and now considered subjectively 

 as representing a taxon that is congeneric with that represented by the nominal species 

 Papilio It vale Linnaeus which (as already noted) Curtis had already selected to be the type- 

 species of the genus Colias Fabricius. 



Partly perhaps because of doubts as to the validity of the method adopted by Latreille in 

 selecting type-species in the Consid. gin. of 1810, that author's selection of Papilio rhamni 

 Linnaeus as the type-species of the genus Colias Fabricius, never won an acceptance and 

 the name Colias came into universal use as the name for Papilio hvale and Papilio palaeno, 

 that is for the group of Pierids known as " Clouded Yellows " in England and as " Sulphurs " 

 in North America. Occasionally, some author pointed out that this usage was incorrect and 

 used some other name, e.g. Eurymus Horsfield, 1829, for this genus, but these efforts were 

 never successful, the name Colias firmly holding its ground as the generic name for the " Cloud- 

 ed Yellows ". This then was the position when in 1933 I was asked by the Royal Entomologi- 

 cal Society of London to draw up a report on the generic names properly applicable to the 

 British butterflies. In the Report then submitted (1934, Gen. Names Brit. Ins. : 34-36) the 

 view was expressed that this was a case where the application of the normal rules in the Code 

 would lead to the most serious confusion, for the deeply-established usage of the name Colias 

 Fabricius would have to be abandoned and that generic name would need to replace the 

 equally well-known name Gonepteryx [Leech], 1815, the genus so named having the same species 

 (Papilio rhamni) as its type-species as Colias Fabricius under the selection made by Latreille in 

 1 8 10 ; in consequence it was strongly recommended that an approach should be made to the 

 Commission for an Opinion preserving the use of the name Colias Fabricius for Papilio hyale 

 Linnaeus and its numerous allies. On the publication of this Report a request in the fore-
