GENERIC NAMES OF BUTTERFLIES 163 



manuscript name. When publishing this name in 1870 Boisduval certainly looked upon 

 himself as its author, treating it as a new name then published for the first time. 



The name Epicalia Boisduval is invalid, as being a junior homonym of Epicalia Doubleday, 

 1844.

 monotypy : Papilio ancaeus Linnaeus, 1758, Syst. Nat. (ed. 10) 1 : 486. 



This name is invalid, as it is a junior homonym of lipicallia Hubner, [1820] {Verz. bekannt. 

 Schmett. (12) : 182), a name bestowed on a genus of moths. 



It is possible that Erichson had heard of the then-manuscript name Epicalia Boisduval and 

 that the present name is only an accidental misspelling of that name.

EPIMEDE Houlbert, 1922, in Obcrthur, Etud. Lipid, comp. 19 (2) : 132, 142, 160. Type-species 

 by original designation : Halimede menetriesi Oberthur & Houlbert, 1922, C.P.. Acad. Sci., 

 Paris 174 : 707. 



The name Halimede menetriesi was introduced quite unnecessarily as a replacement for the 

 name Arge halimede Menetries, 1858, Oberthur & Houlbert taking the view (erroneously) that, 

 following the erection for this species of a genus bearing the name Halimede, the specific name 

 halimede Menetries could no longer be maintained. As originally published, the nominal 

 species Arge halimede Menetries was a composite; the specimen described as the male of this 

 species belongs to the taxon which has always been known by the name halimede Menetri6s, 

 and is now the lectotype of the nominal species so named by Menetries; the specimen treated 

 by Menetries as the female of his Arge halimede is actually a male and belongs to an entirely 

 different species, namely the taxon bearing the name Melanargia meridionalis Feld., var. 

 epimede Staudinger, 1892 (in Romanoff, Mim. Lip. 6 : 196). [The earlier name Melanargia 

 halimede var.? meridionalis {epimede Staudinger in litt.), 1887, though commonly used, is 

 invalid, because it was published in synonymy.] 



It will be seen from the particulars given above that the name Halimede menetriesi Oberthur 

 & Houlbert, 1922, the type-species of the present genus, is a junior objective synonym of Arge 

 halimede Menetries, 1858 {Bull. phys. math. Acad. Sci. St. Petersb. 17 : 216) o* nee " $ " [which 

 is a o* of Melanargia meridionalis Feld., var. epimede Staudinger, 1892].

The name Epimetes Billberg is invalid, as it is a junior objective synonym of Mechanitis 

 Fabricius, 1807.
