14 THE LEPIDOPTERIST 



dagger shaped spot, while in arnica this line runs uni- 

 formly without such a decoration. The last part of the 

 submarginal line where it ends in the costa is Hkewise 

 of a bluish-white color. The space between the pos- 

 terior and the submarginal lines more brown than 

 gray. Black line on edge of primaries twice as broad 

 as in arnica, also of a deeper color. In all other points 

 primaries as in amica. Secondaries as in amica. how- 

 ever, the isolated black spot near the anal angle always 

 is more or less connected with the base through a 

 black band or shade extending along the inner edge 

 of secondaries. In every specimen there is a pronounced 

 black dash extending from the base towards the 

 middle of the secondaries, pointing to the space be- 

 tween the end of the marginal band and the anal spot. 

 Under surface of all wings as in amica. 



9 . In patten and color like the $ , but the space in 

 the median area isolated by costa, transverse shade and 

 posterior line always of a light bluish-gray color in- 

 termingled with brown scales near the posterior line. 

 This light spot is occasionally seen in the $ , too, but 

 it never appears there as distinctly as in the 9 . 



Average size, measured from tip to tip of wings: 

 amica $ 38 mm., 9 40 mm., subsp. novangliae, 

 S 35 mm., 9 37 mm. 



Described from 15^ and 4 9 taken between 1912 

 and 1916 in various parts of Massachusetts, New 

 Hampshire and Maine. Type 1$ l9, (Plate II. 

 fig. 1 and 2) both from Concord, Mass., and collected 

 July 23 and August 8, 1914, in the author's collection. 

 Cotypes in collection of Mr. Samuel E. Cassino and in 

 the author's collection. 



I believe that this subspecies reaches in Connecticut 

 its southern limitations, as I have seen specimens taken 

 at various parts of Connecticut some of which belong 

 to the subspecies and others to amica. 



There is an occasional tendency in this subspecies to 

 bring forth a parallel form to lineella Grote of amica. 

 but none of the specimens as yet seen are sufficiently 

 diverted from the type in this direction to substantiate 

 separation. 



The form nerissa Hy. Edwards of amica has no
