ON THE SYNONYMY OF THREE NORTH AMERICAN BUTTERFLIES. 



There are three North American butterflies, whose nomen- 

 clature is very much confused. These are Danais Berenice 

 of Cramer, Danais Erippus of Cramer, and Limenitis Misippus 

 of Fabricius. The same species have been described under 

 various other names, and the same names have been given to 

 several other species, and have otherwise been misapplied. We 

 have therefore to establish the priority of the names of these 

 three species, and to take care that they do not conflict with the 

 claims of other species. It becomes necessary to identify the 

 species in question with the same as described under other 

 names ; and to distinguish them from the different species de- 

 scribed under the same names ; and lastly we have to de- 

 cide what names these different species shall bear. The neces- 

 sity of doing all this will appear by the following statements. 

 The Berenice of Cramer is the Erippus of Fabricius, but not of 

 Cramer ; and it is the Gilippus of Smith, but not of Cramer and 

 Fabricius. The Erippus of Cramer is the Archippus of Fa- 

 bricius and of Smith, but not of Cramer ; it is also the same as 

 the Plexippus of Cramer, but not of Linnaeus and Fabricius. 

 The Misippus of Fabricius is the Archippus of Cramer, but not 

 of Fabricius and Smith. The Berenice of Cramer is not the 

 Berenice of Drury and Fabricius ; the Erippus of Cramer is not 

 the Erippus of Fabricius ; and the Misippus of Fabricius is not 

 the Misippus of Linnaeus. For the sake of convenience the 

 various specific names with which we have to deal in clearing up 

 the nomenclature and synonymy of these species may be arranged 

 alphabetically.
