980 THE BUTTERFLIES OF NEW ENGLAND. 



heavily marked with brownish fuscous, having a tinge of red. Prothoras with three 

 small, round, brownish fuscous spots on either side, at the angles of a pretty large 

 triansrle, the inner ones laterodorsal ; an obscure fuscous, dorsal line on the front of 

 the niesothorax and a pair of small, round, obscure fuscous spots on the middle of the 

 same ; midway between them and tlic iiinder edge another more distant pair. Abdomen 

 with a lateral, central, a laterostigmatal posterior, a stigmatal posterior, an infrastig- 

 matal posterior, a veutrostigmatal central and double subventral, central scries of 

 similar, often obscure spots on all the exposed segments. Warts supporting fungi- 

 form bristles black ; the bristles wholly colorless. Spiracles luteous, sometimes with 

 an aureous tinge; the raised lines and their warts are of the color of the body. 

 Length, 9.5 mm. ; breadth, 4 mm. ; height, 4 mm. ; length of fungiform bristles 

 above wart, .064 mm. ; of equal portion of pedicel, .047 mm. ; diameter of basal 

 papilla, .015 mm. ; of pedicel, .0085 mm. ; of disc including lobes, .0G4 mm. ; length 

 of lobes, .0085 mm. 



Distribution (25 : 1 ) . This member of the Alleghanian fauna has a 

 somewhat peculiar distribution. Its southern limits — and it appears to be 

 rarer in the southern than in the northern limits of its distribution — seem 

 to be not far from the 39th degree of latitude, or perhaps the annual iso- 

 therm of 53° ; for the southernmost localities from which it is recorded are 

 New Jersey (Andrews), Philadelphia "rare" (Blake) and Cincinnati "not 

 common" (Dury). To the noi-th it has been taken at Lake George 

 (Perot), Lachine "very rare" (Caulfield), Province of Quebec "plentiful" 

 (Fyles), Ottawa "in numbers" (Fletcher), Lansing, Mich. (Miles), 

 Racine, Wise. (Hoy), and even at Nepigon north of Lake Superior 

 (Fletcher), and recently by Mr. Tyrell at Miry Creek and Vermilion 

 Kiver in the north Saskatchewan region (Fletcher), these last localities 

 about doubling its previously known range. Throughout New York 

 (including the Adirondacks), northern Ohio, Indiana and Illinois, as well 

 as southern Ontario and Michigan it is common, and it has been taken 

 westward on this range in Iowa (Parker, Putnam), Minnesota (Scudder) 

 and eastern Kansas "rare" (Snow), and according to Edwards in 

 Nebraska and Colorado. The reference to its occurrence in Newfoundland 

 given by me in the Buffalo Bulletin is, I think, an accidental error. I can 

 find no authority for it. 



In New England it has never been taken east of the Connecticut valley, 

 and the rejjorted captures are few. In New Hampshire the White Moun- 

 tains (Sanborn), Walpole "one specimen" (Smith) ; in Vermont, Stowe 

 one specimen (Miss Soule) ; in Massachusetts, Springfield "not uncom- 

 mon" (Emery, Dimraock), Amherst (Marsh), Mt. Tom (Alorrison), 

 Belchertown and north Leverett (Sprague), Lenox "common" (Edwards) 

 and Williamstown rather rare (Scudder) ; in Connecticut, New Haven 

 "not uncommon" (Verrill, Harger). 



Haunts. The butterfly frequents moist meadows, salt marshes, and tlie 

 springy margins of brooks. In the salt marshes. Professor Verrill found 

 it among the sedges. It seems nowhere to be a very abundant insect, and 

 is only not so local as Epidemia epixanthe.
