Lycaena enoptes, battoides and glaucon (Lepid.). 

 BY HENRY SKINNER, M.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 different 

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

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

 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 enoptes 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 glancon also a 

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

 lowing localities : 



California material has been received from Havilah, June n 

 (F. Grinnell, Jr.), also June 19, Pasadena; June 7 and 13 

 (Louis Wanka) ; Soldiers' Home (Max Albright) ; Brodie, 

 July 3 (H. F. Wickham) ; Truckee, Sierra Nevada; Los An- 

 geles, June 7; Eldorado County, June 19 (6800 ft.). There 

 are also specimens with only a State label. 



Las Vegas, Nevada, May I and June 5 (Thomas Spalding). 



Fort Klamath, Oregon, June 12 to 26 (B. L. Cunningham). 



Chimney Gulch, Colorado, June 18 and 20 (E. J. Oslar). 

 These are the only Colorado specimens with accurate data, the 

 others bearing a label "Colorado, Bruce." 



Park City, Utah, July i and 3 (A. J. Snyder) ; City Creek 

 Canyon, Salt Lake City, Utah, July 5 (Henry Skinner) ; Stock- 

 ton, LJtah, June 10 to 26 (Thomas Spalding), also July 3; 

 Provo, Utah, July 28, 30 (Thomas Spalding).
