One remarkable variation in the male, evidenced by five speci- 

 mens in my series is sufficiently distinct to deserve a varietal name. 

 I will therefore designate this. 



Plebeius carolyna, form nov: naming it for my loyal co-worker 

 and wife, Dr. Carolyn Comstock, who captured three of the five 

 specimens in my series. 



Expanse — 19-25 mm. 



Upper surface as in typical chlorina, i. e. ground color, lustrous 

 blue-green; outer margin brown; fringes white. The nervules on 

 outer third or fourth of primaries, orange (as in neurona) beginning 

 at a point about one mm. internal to outer margin, these orange 

 lines expand as they approach the junction between the blueish- 

 green ground color and the marginal band; they again gradually di- 

 minish as they* approach the limbal area, until they finally disappear. 

 Secondaries, ground color bluish-green. Outer marginal orange band 

 wide, and bordered internally with 5 points of shading in juxtapo- 

 sition to the five submarginal round spots. A dark fine marginal 

 line. Under surface, as in typical chlorina. Thorax, dorsal sur- 

 face blackish covered with filamentous greenish scales; beneath, 

 greyish-faun. Abdomen, dorsal surface dark shading to grey lateral- 

 ly, ventral surface, silvery grey. 



Antennae, clubs black, segments annulated black and white. 



Type locality: Tehachapi Mts. about five miles from the town 

 of that name. Elevation 5,000 feet. The type taken, on July 1st. 

 Paratypes 1, 2, 3 and i, taken respectively on July 7, July 11, and 

 July 22. 



Type and paratypes in the Southwest Museum Collection. 



This form is in practically all respects similar to chlorina, but 

 may at once be distinguished by the orange lineation on the nervules 

 in outer portion of primaries. Possibly it may have arisen as a re- 

 sult of interbreeding with neurona, which is found in the same lo- 

 cality. 



Plebeius emigdionis, Grinnell. Ent. news, Vol. 16, p. 115, 1905. 



This species was first described by Fordyce Grinnell, Jr. from 

 specimens taken in San Emigdio Canyon, Kern Co. Doubt was later 

 thrown on the validity of the species by Mr. Karl Coolidge's notes in the 

 Entom. News of 1907, Vol. 18, p. 300, who states "a later examination 



of Mr. Grinnell's specimen proves them to be all females, and 



emigdionis is probably only a variety of acmon."
