Hauitat. — Mount Marcy, Adiioudacks, New York, July. 



The only specimeus which 1 have seen arc females, and all of those 

 now before uie were taken by the late Mr. W. W. Hill, in 1S82, and are 

 l)art of the lot from which Mr. Grote obtained his types. They are from 

 the collections of the United States National Museum and Dr. J. A. 

 Lintner, and [ am not aware of other specimens, except in the Hdl col- 

 lection. It is quite probable that the species is locally common, and 

 at all events I can testify to the abundance of small, obscure forms com 

 ing to light and stirred out of the scant vegetation near the top of 

 Mount Marcy, where 1 spent a bitter cold night one August more years 

 ago than I care to count. 



The possible relation of this species to Z. minoralis has been already 

 discussed.

Ground color varying from carueous gray to deep red, leather brown, 

 or even blackish. Head and thorax usiudly of the palest color found 

 on the primaries. Primaries with the transverse anterior line ui)right, 

 or nearly so, varying somewhat in direction and sometimes with a 

 small outward angulation on the subcostal. Transverse posterior line 

 even, slender, with a bold outcurve over the cell and a small incurve 

 in the submedian interspace. Subterminal line pale, slightly and 

 irregularly sinuate, emphasized by a more or less marked preceding 

 black shade, and sometimes followed in a similar way. A series of 

 black terminal lunules varying greatly in distinctness and sometimes 

 absent. Orbicular present as a distinct black spot in some specimens, 

 entirely absent in others. Reniform always present, but varying from 

 a distinct, black, kidney-shai)ed si)ot of good size to a slender indefinite 

 dusky luiiule. Secondaries varying from smoky gray to brown or 

 blackish, with a dark extra median line, a pale subterminal line, a 

 series of black terminal lunules, and a rather vague discal spot, which 

 is sometimes wanting. ]>eneath, varying from smoky gray to red brown, 

 powdery, with a common outer dark line and a discal Innule on all 

 wings. In some cases there is also an incomplete subterminal line, 

 best marked on the secondaries. 



Expanse of wings, 27 to 32 mm. = 1.10 to 1.32 inches. 



Habitat. — Canada to Southern and Central States; South Dakota; 

 July to August. 



It has been already indicateil that this is an exceedingly variable 

 species, and yet it is always readily distinguished, not only by the 

 characters already given in the introductory remarks, but because it is 

 really the only one of the genus with contra.sting coloration. Ten
