Distribution (21: 5). This species belongs strictly to the Alleghanian 

 tauna, rarely surpassing its limits in the east, but occurring more abundantly 

 in its southern than in its northern half; so, too, it is apparently more com- 

 mon in the east than the west, although it extends as far as Wisconsin 

 (Chamberlin, Hoy), Iowa (Austin, Osborn), Osage Co., Missouri 

 (StoUey) and even to Kansas "common" (Snow), Nebraska and Dacotah 

 (Edwards) and, if rightly determined, Fort Edmonton, northern Alberta 

 (Geddes) ; Mr. Fletcher informs me that it has also been taken at Miry 

 Creek on the North Saskatchewan and on the Red Deer River near Rocky 

 Mountain House, neither far from Edmonton. The most southerly locali- 

 ties from which it has been reported are Kanawha County "abundant" 

 (Edwards), Elk River, W. Va. "plenty" (Edwards) and Draper's Valley, 

 Va. (H. E. Scudder). It is comparatively rare in the northern cpiarter 

 of the fauna, but (if the species has always been accurately determined) it 

 has occasionally been taken as far as Quebec (Bowles), Montreal com- 

 mon (Caulfield), Ottawa common (Billings, Fletcher), Victoria County 

 (Mead) and London, Ont. (Saunders), in southern Michigan "not com- 

 mon" (Harrington) and at Sault St. Marie, Lake Superior (Bethune). 

 It has not been recorded from Nova Scotia or New Brunswick, but a 

 single specimen was brought from Cape Breton by Mr. R. Thaxter. 



In New England, where it is scarcely larger than A. aphrodite, the two 

 have been frequently confounded, but cybele is found probably throughout 

 the whole area, excepting the White Mountain region and perhaps a part of 

 the region north of it : in the northern half of New England it is uncom- 

 mon, but in its evtreme south exceedingly abundant. The most nor- 

 thern (and, for the Maine localities, the most eastern) places whence it 

 has been received are Portland (Lyman), Brunswick (Packard), Hallo- 

 well "very common" (Miss Wadsworth), Bangor (Davis), Waterville 

 (Hamlin), and Norway, Me. (Smith) ; Isles of Shoals "not common' 

 (Thaxter), Suncook "common" (Thaxter), Milford "very abundant'' 

 (Whitney), AValpole (Smith) and Plymouth, N. H., common (Scudder) ; 

 Miss Soule found it abundant in StOAv, Vermont, and Gosse appears to 

 have taken specimens at Compton, Canada. 



Haunts. The butterfly is found in open fields, sucking the juices of 

 flowers ; it is very fond of thistle, milk weed (Asclepias) and iron weed 

 (Vernonia), the latter of which it shares in West Virginia, says Mr. 

 Edwards, "with innumerable Papilios, Vanessae and Hesperians, and 

 occasionally an aphrodite and diana." Captain Geddes found it "at- 

 tracted bv the blossoms of the numerous vetches which occur" in Alberta.
