30 SATYRUS RIDINGSII. 



of tlie first and second median veins, in the space between these latter is another black spot, 

 smaller than the one towards the costa, but, like it, pupiled with white. The basal third of 

 wing is of a lighter color than the remainder, and in some examples yellow white, almost as 

 pale as in the sub-marginal bands. 



Secondaries also have a sub-marginal pale band which is toothed on outer edge. 



Edges of all wings margined with a narrow brown line; fringes grey and white. 



Under surface yellowish and pale brown ; the bands and spots same as on upper side ; on 

 primaries all the space not occupied by the broad band is marked with little wavy brown 

 lines as is usual on under surface of most species of Satyrus. Secondaries have a sub-basal 

 line, the space between which and the inner edge of sub-marginal band is darker than rest of 

 wing, after the manner of the Chionobas; whole surface of wing covered with little lines; 

 veins white. 



Female. Expands 1| inches and resembles the male. 



The types were taken by Mr. Ridings at Burlington, Colorado; the two which Mr. 

 Edwards afterwards redescribed as Ch. Stretchii, were captured by Mr. Stretch in the vicinity 

 of Virginia City, Nevada, on the hill-sides, early in Spring ere the snow had melted away. 



Mr. Mead took a number of this species in Colorado in 1871, his examples as a general 

 thing are I believe lighter colored than the original types. 



S. Ridingsii belongs to the same group and strikingly resembles the Caucasian S. Hip- 

 polyte, Esp.* and still m*re so the Turkish S. Beroe, Frr.,t it also bears much similarity in 

 appearance to Coenouympha Thyrsis Frr.J found in crete.

Head and body brown. 



Upper surface brown of much the shade and depth as in Alope and Boojjis ; on primaries 

 are two small black round sub-marginal spots with minute white centres ; below the median 

 vein is the oblong patch of short dense dark grey down peculiar to this sex. On secondaries 

 is a dark sub-marginal line ; Fringes of all the wings pale with dark alternations at termi- 

 nations of nervurcs and nervules. 



Under surface, primaries brown, in sub-marginal space are two large round black spota 

 with white pupils, and surrounded by yellow rings ; a dark brown sub-marginal line ; the 

 space interior to the two ocelli is marked with the lines so peculiar to the Satyrides. Costa
