THE BUTTERFLIES OF NEW ENGLAND. 



Described from 103 , 11 9 . 



Accessory sexual peculiarities. The discal stigma of the male has been described 

 under the wiiiirs; the scales contained in it consist of slender and equal jointed threads 

 (50 : 4 b) in the heart of the stigma; at the extreme base of the stigma a collection of 

 rods or narrow scales of two forms, some(4 a)long and slender with rounded apex, and 

 tolerably broad throughout, narro\ving very slightly toward the base, others much 

 slenderer, more rod-like scales (4 h), abruptly truncate at tip, very slender and scarcely 

 enlarged from base to apex ; some exceedingly long and slender spatulate hairs are 

 found, with long oval spatulae, some near the base of the stigma (4 c), others at the 

 extreme tip (4 f ) ; above the apical member of the stigma is found a cluster of two- 

 pronged rods (4 g) , while in the field below the stigma in the median interspace are 

 some toothed scales (4d, e),the teeth well rounded and irregular, the scales them- 

 selves of varying form but always broad. 



Distribution (32:4). So far as yet known, this butterfly is confined 

 to the Alleghanian fauna, but it has been found at widely separated locali- 

 ties ; passing from west eastward these are: Nebraska (Edwards), 

 Grinncll, Iowa (Parker), Wisconsin (Hoy), Lansing, Mich. (Edwards), 

 Hudson City, N. J. (Lintner), and another locality, probably in New 

 Jersey (Merrill). According to a determination of Strecker it has been 

 taken in Montreal by Caulfield ; and Strecker gives also Minnesota, 

 Indiana and Ohio. I have specimens also from Illinois and from Brooklyn, 

 N. Y. 



In New England it has only been reported from the vicinity of Boston, 

 where it has been taken in Cambridge and Jamaica Plain by Morrison, and 

 in Maiden and Wollaston by F. H. Sprague. 



Life history. The only clue to the life history of this insect is furnished 

 by the memoranda taken by Messrs. Morrison and Sprague of their cap- 

 tures about Boston. The butterfly has only been taken in July, at least as 

 early as the 10th and as late as the 27th ; one year, on the 10th, Mr. 

 Sprague took twelve males and one female, all new ; on the 12th he found 

 the male very common and took three or four females, and both male and 

 female were common and good on the 17th ; specimens taken on the 27th 

 were rubbed. In Iowa, Professor Parker found them in great abundance 

 in 18(S4, whereas in former years they were very rare. 



Desiderata. Tlie poverty of the above account sufficiently shows that 

 no facts, even the merest records of capture with sex and condition, can 

 fail of adding to our knowledge of this modest looking butterfly ; of the 

 early stages we know nothing. Its western distribution is very likely 

 much greater than indicated on the map.
