Lycaena enoptes, battoides and glaucon (Lepid.)- 

 By Henry Skinner, ]\I.D., Philadelphia, Pa. 



This is a comparative study from the specimens at hand, 

 no types having been seen and the descriptions being relied on. 

 These three names represent the great difficulties encountered 

 in a study of our butterflies, especially species of some of the 

 earlier authors. The name species represented quite a diflFerent 

 idea from what it does to-day. and slight differences in appear- 

 ance were often taken to represent distinct entities in nature. 1 

 could never with any degree of satisfaction find butterflies that 

 would adequately fit these three names as distinct species. The 

 type of battoides Behr. I assume, was destroyed in the San 

 Francisco fire. The type of cnoptes Boisduval may, or may not, 

 be in the Oberthur collection in Rennes, France, and the type of 

 glaucon Edwards is doubtless in Dr. W. J. Holland's collection 

 in Pittsburg, Pennsylvania. 



After a careful study of the original descriptions, in conjunc- 

 tion with a fair amount of material, I have come to the con- 

 clusion that the three names represent but one species. Bat- 

 toides I take to be a variety of enoptes, and glaucon also a 

 slight variety. I have studied sixty-five specimens from the fol- 

 lowing localities :
