In 1878, Mr. Herman Strecker briefly described, in 

 his Catalogue of Butterflies, a Southern form as darker 

 than ArchippuSj under the name Var. Floridensis, but 

 gave no marks of difference except the color. In the 

 December number of the ^^ Canadian Entomologist" 

 for 1880, Mr. W. H. Edwards, recognizing two forms 

 in the Southern States as differing from L, Archippus de- 

 scribed the one farthest separated from Archippus as X. 

 EroSj presuming that the other form was Mr. Strecker's 

 var. Florldensis : the one described as Eros contained 

 points of difference besides color, and Mr. Strecker's de- 

 scription made no mention of any other distinction. In 

 a subsequent number of the " Canadian Entomologist" 

 Mr. Strecker claimed that Mr. Edwards had redescribed 

 his variety Floridensls; but the New York Entomological 

 Club sustained Mr. Edwards in his name Eros for the 

 form to which it was given. Following that decision, 

 the two names are used in that way in Mr. Edwards's 

 New Catalogue, and the nomenclature here is based on 

 that arrangement.
