Ground color liiteous, with blackisli iiiid l»i-((\vii powdcriii.iis. Head 

 and thorax (•oiu'.ok)roiis. I'litnaiics \\ ith tlie powdciiiiiis (h'lisc. though 

 irregiUaily distiibutcd, giviii|L; the \viii<;s a. peculiarly sordid or dirty 

 ai»])earance. IJasal line faintlymarked in some specimens. Transverse 

 anterior line blackish, rarely distiuct, often diffuse and indefined, with 

 two even outcurves in its course. Transverse posterior line slendei', 

 irregular; a little marked on the veins, irregularly outcurvecl over the 

 cell, somewhat incurved beneath; often diffuse and sometimes almost 

 obsolete, except on the costa, where it is somewhat dilated. Subtermi 

 nal line irregularly sinuate, pale, marked by a more or less distinct 

 a]>ical blotch and ]>receding shade, Avhich becomes inwardly diffuse and 

 sometimes darkens a large ]»art of the snbterininal space. A narrow, 

 black, int<'nu]>ted terminal line. A broad, diffuse, indefined, abnost 

 upright, smoky median shade, involving the reniform, which is usually 

 a narrow lunule, but sometimes a more prominent oval, though not 

 defined, blotch. There is sometimes a vague trace of an orbicular. 

 Hecondaries paler, varying in shade, always i)owdcry, with an indefined 

 median shade line, more obvious in pale specimens, and an incomplete 

 snbterminal line, which is pale and preceded by a dark shade toward 

 the hind margin; occasionally this line is comi)lete, and then the ter- 

 minal space is somewhat paler than the rest of the wing; beneath 

 brighter yellowish, with ocherous powderings. Tliere is a distinct, 

 common, brown median line, a distinct discal lunule, which on the 

 secondaries is sometimes faintly visibh' on the ui>per side, and a vague, 

 incomi)lete outer line. 



Expanse of wings, 25 to .'>() inm. = l to l.l'O inches. 



Habi'i AT. — Canada to Virginia, west to Iowa; South Dakota. June 

 and July. 



The species is common and varies little. It is usually a question of 

 a more or less dense dark ])owdering and the corresponding obscurity 

 of the ordinary lines. 



In the male the antenme are bipectinated, the i)r()cesses long, some- 

 what enlarged toward the tip, near which is inserted a long, curved 

 bristle, the surface smooth, without scaly markings, but with obvious 

 l)ittings. and they are quite abundantly setose. 



The foie legs of the male are ([iiite different from the j^receding 

 species. The coxa is long, slender, and with a pencil of scale like hair 

 at its tip. The trochanter is long, scarcely shorter than the femur. 

 The femur is stout and on the under side furnished with a dense pencil
