AMERICAN LEPIDOPTERA. 69 



Female. — Expands 1.8 inch. Upper side paler, yellow-fulvous be- 

 yond disk; yellow spots larger; under side iron-grey, suffused at base 

 with brown; the markings nearly obsolete ; discal spot nearly obsolete ; 

 sometimes this is a narrow line bent at an obtuse angle. 



From about 20 specimens taken in Colorado, in August 1871, by 

 Mr. Mead. These were found in company with G. Zephyrus and 

 Vannessa Antiopa. The species is near Faunus in many respects but 

 differs decidedly in the coloration of under surface, and in the shape 

 of the silver mark. The upper side also shows nothing of the in- 

 tense fulvous of Faunus. 



Satyrus Charon, n. sp. 



Jsf<*fe.—Expands from 1.5 to 1.7 inch. Upper side dark brown ; 

 hind margins bordered by two fine parallel lines, a little anterior to 

 which is a third line, not distinct; primaries have a blackish band 

 along posterior side of cell, as in S. Silvestris; also two ocelli be- 

 yond disk, the upper and larger always present, the other some- 

 times wanting, or a mere point; these are black in faint yellowish 

 rings, though the rings are sometimes obsolete ; fringes of seconda- 

 ries brown, of primaries brown mixed with grey. Under side of 

 primaries brown with a slight tint of yellow ; the marginal and sub- 

 marginal lines distinct ; costa and apex greyish ; the basal portion 

 streaked with brown ; the ocelli black in bright buff rings and with 

 white central dots; secondaries brown mottled with grey, especially 

 on outer limb and next base, and throughout much streaked with 

 brown ; the inner of the two marginal lines diffuse and the sub-mar- 

 ginal much scolloped towards outer angle; the disk crossed by a 

 dark band with blackish irregular edges; the ocelli minute, consist- 

 ing of black spots with white central dots, and varying from one to 

 six on individuals. 



Body, legs and palpi dark brown; antennae annulated with brown 

 and whitish above, whitish below ; club pale fulvous. 



Female. — Expands 1.7 inch. Paler than the male, but similarly 

 marked. 



This species was first met with by Mr. Mead, in Colorado, near the 

 Twin Lakes, in Upper Arkansas Valley, (elevation 80UO feet) in July 

 1871. It flew near the ground, frequently alighting on the sage- 

 brush, aud seemed much more partial to flowers than was Satyrus 

 Ridingsii, also common in that vicinity. By the latter part of July it 

 was abundant throughout the entire Park and mountain country and 

 so continued till September.
