Alae subtus cinereae, linea discoidali serieque punctorum nigrorum dilutius 

 cinctorum refracta signatae. Posticce punctis tribus nigris dilutius cinctis radi- 

 calibus insuper instructse. Lunularum series duplex, interior nigra exterior 

 dilutior, apicem versus analem puncta nonnulla aurantiaca amplectens. 



This species I received also from Mr. Hoffmann, who found it associated with 

 L. Dmlalus. It is the Californiau analogue of the European Agestis, and pro- 

 duces on one somewhat the impression of a Polyommatus.

This species I also received from the Geological Survey. It was found at an 

 elevation of 11,000 feet and over, on the snowy heights surrounding the head- 

 waters of the Tuolumne River. It belongs to the type of the European Orbit u- 

 lus, which is found in similar regions of the Alps.

Alae $ cincta? supra lilacinae fusco marginatae albo limbatae, $ nae supra

Alae j ris subtus albidae, $ nae lacteae. Linea discoidalis parum distincta. 

 Series punctorum vix halone cinctorum in anticis stricta, in posticis refracta. 

 Pars radicalis anticarum concolor, posticarum nonnullis punctis minimis sed 

 distincte halone cinctis signata ; lunularum series marginatum duplex sed 

 parum distincta, spatia fulva amplectens, quae tamen non semper distingui 

 possuut, in posticis lunula? exteriores seriei splendore metallico micantes. 



Alae $ na3 subtus magis distincte signatae ; spatia fulva submarginalia uec 

 non splendor metallicus lunularum distinctius videtur. 



This species is found in the Sierra Nevada. It is very similar to L. Scudderi 

 of the Atlantic coast, and may prove to be only a local variety of that species, 

 from which it differs chiefly in the shape and arrangement of the submarginal 

 markings, which, however, in the Atlantic coast specimens, are much more dis- 

 tinct than in those from California.
