McGlashani is a trifle more red on fore wings than Chalcedon, 

 but the species might easily be mistaken for Chalcedon, as the sys- 

 tem of markings is similar on each. These examples were taken 

 by me in the typical locality of the species, which is quite local. 



The larvae feed on a species of pentstemon, a small plant less 

 than a foot in height, and on which I have secured eggs in abun- 

 dance, by confining the mature female in a small gauze bag, over 

 the plant.

Expanse, i^ to 1% ; black ; red marginal lunules to all wings ; 

 large chalky-white spots, on the Chalcedon plan, with four red 

 spots on the costal half of fore wing ; hind wing has three rows of 

 chalky-white spots ; basal area very black, with three or four small 

 white spots. Underside, all spots chalky-white, arranged as in 

 Chalcedon, all, except at inner angle of fore wing, lightly out- 

 lined with black ; on fore wing, between cell and apices, a large 

 black oval transverse spot. 



A high mountain species, the highest known to me, taken at 

 about 11,000 feet elevation, on Olancha Peak, some thirty miles 

 south of Mt. Whitney ; a most difficult region ; on the dividing 

 line between the desert and the wooded, mountainous region of 

 the crest of the Sierra Nevadas. Taken by Mr. Stephens, the 

 California mammalogist and ornithologist.

 Editha and Rubicunda, the next species, are closely allied ; the 



chief diiTerence seems to be in the tint of the red color ; Editha
