species on the wing. A little further up, Hrebia stygne—the 
first Hrebia of the year for me—put in an appearance, and was 
almost common at about 5000 ft. The form differs materially 
from that of Digne and the Midi—it is much smaller, and, I 
think, blacker—more resembling examples from the Vosges in 
my collection, taken last year by Mr. Barraud and Mr. Gibbs 
(antea, p. 115, &c.); the ocellations, moreover, are decidedly in-

August, 1909 (the upper), and a normal form of Polyommatus escheri from St. Mar- 
tin-Vésubie, Alpes-Maritimes. (2) The two lower figures represent (to the left)

valesiana, M-D., after Mr. Wheeler’s description. But with these

thami with very pale under side coloration, the catalogue for the 
day came to an end, save for an extremely battered Hipparchia 
semele circuiting the topmost Plomb, where the tremendous wind 
which had sprung up effectually disconcerted both butterfly and
