Ground (;olor Avhitlsh ashen gray, with a vague yellowish tinge 

 thionghont. Head and thorax without markings, save the usual black 

 line IVom the [)alpi to the base of the wings, which extends a little on 

 the thorax in this case, and is somewhat conne<;ted by a more or less 

 evident liin; across the front of the head. The primaries have all the 

 ordinary niaikings very distinct. Basal line gen)inate, well niaiked 

 on the costa. Transverse anterior line geminate, well marked on costa, 

 but more feeble beyond that point and in rare cases entirely wanting. 

 As a whole it is quite even and outwardly oblique. The median line 

 is marked on the costa by an oblique shade, which reaches to and a 

 little darkens the center of the reniform. The transverse posterior line 

 is lunulate, continuous, strongly outcurved over the cell and incurved 

 beneatli. The black luniile is preceded by a distinct whitish shade, 

 which renders the line decidedly more prominent. The snbterminal 

 line is pale, more or less incomplete, not defined, and in some cases 

 almost at tlie base of the fringes. There is a series of black terminal 

 dots, beyond which the fringes are cut with black. In well-preset ved 

 specimens it is seen that the fringes are also interlined. The basal 

 bla(;k streak is very heavy and prominent, extends clean across the 

 transverse anterior line, and usually a little into the median space. In 

 many specimens the internal vein is well marked with black through 

 nearly the entire median space. There is a distinct daggei- mark oppo- 

 site the cell, which usually crosses the transverse posterior line, and 

 there is another much heavier dash which (;rosses the line in the sub- 

 median interspace. The ordinary spots are well marked and of the 

 ground color. The orbicular is round or nearly so, well defined inferi- 

 orly, but usually not complete above. The reniform is large, kidney 

 shaped, well marked interiorly, but rarely complete outwardly. A dis- 

 tinct black line connects the two spots along the lower margin. 

 Secondaries smoky, sometimes considerably paler in the male. Beneath
