the cells grow rapidly more and more punctuate, and when a radius of .007j from the

 the abdomen with longer hairs, half as long as the segment but not recurved. 

 Described from drawiugs lent by Mr. Edwards. 



Distribution (31 : 2) . This butterfly is a characteristic member of the 

 AUcghanian fauna, but extends also soutli, and perhaps to some extent north, 

 of its limits ; in tlie Carolinian fauna it does not seem to have been taken 

 south of the Virginias, excepting in northeastern Florida (Scudder) and at 

 Indian River (Edwards). Mr. Billings credits it to Ottawa, and Mr. 

 Fletcher says it is very common there, but the only other places in Canada 

 where it has been found are London, Ont., "very rare" (Saunders), 

 Montreal, one specimen (Caulfield) and Chateauguay Basin (Pearson).* 

 In the Alleghanian fauna it occurs from the Atlantic to Iowa (Allen, Put- 

 nam) and eastern Kansas, rare (Snow). 



In New England it is mostly confined to the southern half, having rarely 

 been taken north of 43° 30' N. L., the northernmost localities being 

 southern Vermont (Scudder), Dublin (Faxon), Milford (Whitney), and 

 the White Mountains, N. H., rare (Sprague) ; Hallowell, very rare (Miss 

 Wadsworth) , and Portland, Me. , common (Lyman) ; Andover (Sanborn) , 

 and Pelham Hills, Mass. (Parker) ; on Cape Cod and along the southern 

 shore as well as on Nantucket, it can always be found in considerable, 

 sometimes extreme, abundance, but varies elsewhere according to the 

 year. 



Haunts. The butterfly frequents the open country, and is exceedingly 

 fond of flowers, and is always easiest captured on them ; it especially de- 

 lights in asters, golden rod and thistles. 



Oviposition. All the eggs I have seen were laid in confinement, the 

 first ones in boxes sent me by Messrs. Whitney and Hambly ; most of 

 them were unattached ; of those which were attached some were placed on 



* In this instance, however, the identification if Pearson's specimens were taken, as he 

 of the species is almost certainly wrong, says, June 30 and July 1.
