same interspace ; it encloses a minute black dot ; in the middle of 

 the cell, seated upon the median nervure, is a white spot a little 

 smaller, containing an ordinarily obsolete black dot; and upon the 

 internal border and the broad white band is another, similar in all 

 respects to that in the cell ; these last two white spots are themselves 

 sometimes obsolete. 



Body black, covered above with long silver-gray hairs, and blackish 

 scales; beneath with whitish hairs and scales; legs testaceous, covered 

 closely -with white scales ; scales at the side of the palpi snow-white, 

 the hairs gray; last joint above dark-brown; eyes rimmed with a 

 distinct row of pure white scales, and these bordered on the front 

 with blackish hairs, between which down the middle of the front runs 

 a row of silver-gray hairs. Antennae very dark velvetty-brown, an- 

 nulated with pure white, narrowly above but with scattered scales, 

 giving the sides and under surface a hoary appearance ; club dark 

 velvetty-brown above, with a few scattered white scales on the side ; 

 beneath dull, dusky ferruginous. Expanse of wings, 24 mm. 5 J, 

 9 ?. 



Hopedale, Aug. 3 ; Henley Harbor, Aug. 15. First observed at 

 Sloop Harbor, Kynetarbuck Bay^ July 19 (Dr. A. S. Packard). 



This insect scarcely seems to be the same as that described, by 

 Curtis, in Ross's second Voyage, as Polyommatus Franklinii, so much 

 does it differ from the figure and description given there. The upper 

 surface of the wings is not " grayish powdered with silvery-green, 

 especially at the base," as there desci-ibed ; nor is the under surface 

 of the hind wings, " fuscous freckled with gold, but blue at base." 

 The figures given differ from my specimens in the particulars given 

 above, and also in that the mesial row of black spots on under sur- 

 face of the fore wings has but a very slight curve, while the mark- 

 ings outside of this row along the border are not as in the specimens 

 before me. On the under surface of the hind wings, Curtis's figure 

 represents the broad, white band as reduced to a row of circular 

 white spots, scarcely extending so far across the wing as my speci- 

 mens always show it, and the markings beyond them along the mar- 

 gin differ from my specimens even more than the border of the fore 

 wing ; yet it is undoubtedly very closely allied, and a true represen- 

 tative of this species. Ross's two specimens were taken " on Astraga- 

 lus alpinus near the end of July."
