370 I-El'lDOl'TERA. 



basal two-tliirds of the wiug mottled Mack-brown, with the 

 space between the basal blotch and the central band faintly 

 dusted with bluish white ; outer edpe of this dark area per-

 faint, more or less hooked, indentations; hinder area creamy

 more black dots, forming a blackish streak below the apex ; 

 cilia black mixed with white. Hind wings smoky brown > 

 cilia the same but shaded with white. Female similar.

Lakna unknown. 



This species is thought by some to be a mountain variety 

 of P. savciana, but of this I am not satisfied. The late 

 Thomas Eedle when collecting in Scotland in the year 1872 

 took a number of specimens on the mountains of Perthshire, 

 always at a great elevation, and " among Arctostaphi/los uvu- 

 ursi flying late in the afternoon in a quick jerking manner, 

 darting straight forward, and when pursued dropping down 

 among the heath and bearberry, where it hides itself and 

 cannot be induced to rise again. It flies in June. The larva 

 probably feeds on the bearberry in the spring." Mr. Eedle 

 went on to point out a difference in its mode of flight from 

 that of F. sauciana, which was flying at the same time in a 

 lively manner in the sunshine. More recent observers have 

 taken it among Vaccinium mip'ti/lus, at 2000 to 3000 feet 

 above the sea-level. The only locality which I know for this 

 species is on these Perthshire mountains. It has not, I 

 think, been noticed abroad.
