gray, brown, aud yellow scales. Basal line geminate, black, both por- 

 tions equally distinct, usually pale filled, outwardly angulated on the 

 median vein, beneath which a line of black scales may connect this 

 angulation with the transverse anterior line. Transverse anterior line 

 geminate, diffuse on the costa, outer part broad, black; inner narrower 

 and blackish; included line always paler and sometimes yellowish; in 

 course outwardly oblique, with outcurves in the interspaces. Trans- 

 verse x)osterior line geminate, inner blackish, lunulate rather than 

 crenulate, the outer smoky, even; its course is a rectangular bend over 

 the cell, aud then parallel with the outer margin or a little incurved to 

 the inner margiu. Subterminal line always evident, pale, sometimes 

 punctiform, usually marked by the darker terminal space, and some- 

 times by a preceding broken or continuous shade as well, forming a 

 small W on veins 3 and 4 when best marked. Median shade quite dis- 

 tinct, oblique between the ordinary spots, then rather close to and 

 parallel with the transverse posterior line to the margin. Claviform 

 moderate or small, concolorous, often incomplete, but always at least 

 partly outlined in black. Orbicular moderate or large, oblique, oval or 

 irregular, more or less completely black ringed, annulate with violet or 

 yellowish, the center paler than the ground, so that the spot is relieved 

 without being really contrasting. Orbicular large, kidney-shaiied, 

 extending well below the median vein, laterally outlined by black 

 scales, incomplete above and below. An annulus of yellow or violet 

 scales lies within the black margin, and these scales encroach from the 

 concave outer border and sometimes nearly divide the spot. The center 

 is of the ground color, but darkens inferiorly, and it may be relieved 

 by a pale central lunule. There is a series of black terminal lunules, 

 and a pale line at the base of the fringes. Secondaries soiled whitish, 

 with a smoky outer margin, broader and darker in the female, the 

 yellowish tinge very faint, yet perceptible. Beneath gray, powdery, 

 with the usual outer line and discal spots all more or less evident. 

 Thoracic vestiture an admixture of scales and flattened hair, patagisB 

 relieved, tuftings well marked. 



Expanse, 32 to 36 mm.= 1.28 to 1.44 inches. 



Habitat. — Pullman, Washington, July and August (Piper) ; Dakota. 



Size and general habitus of tessellata without the black filling, and 

 much mottled and powdered; more like friabilis, but smaller and some- 

 what shorter winged, not so evenly gray. The male seems to resemble 

 tessellata most nearly in habitus, whereas the female tends rather to 

 messoria in the better defined median shade. Ten specimens, equally 

 divided as to sex, are under examination.
