 the opening of the copulatory pouch at the upper inner angle, taking 

 in the angle itself and not any material portion of either upper or 

 inner margin.

Ground color a dirty luteous gray or brown, more or less tinted 

 with red brown. Head with a brown or black frontal line. Collar 

 with a more or less obvious black or brown medial line. Thorax 

 with obscure transverse light and dark alternating shades. Abdomen 

 gray to luteous, the dorsal tuftings small. Primaries with the trans- 

 verse markings usually distinct and the s. t. line, at least, black and 

 contrasting. Basal space usually darker and sometimes contrastingly 

 so. Basal line marked in some specimens; usually as a dark shade 

 between pale marginal lines. T. a. line always obvious, geminate, 

 brown, the intervening space tending to darken so as to form a band, 

 and in such case often preceded by a paler line. Median space 

 usually paler at the t. a. line than elsewhere, and darkening from the 

 middle outward; but it may be absolutely concolorous, may have a 

 pair of nearly upright diffuse median lines, or may be simply washed 

 with darker outwardly. Orbicular a black or brown dot, distinct in 

 most of the specimens. Reniform of moderate size, lunate, uniformly 

 dusky or blackish, edged with yellowish scales. T. p. line slender, 

 threadlike, usually black, tending to become lost inferiorly, out- 

 wardly bent over cell, roundedly indented opposite reniform, thence 

 from vein 4 inwardty oblique and sinuate to the margin. S. t. line 

 black, usually complete, sometimes broken opposite the reniform and 

 occasionally obscure toward costa. It is irregular and a little dentic- 

 ulate in the upper part of its course, forming an incurve from costa 

 to vein 4. where it is outwardly dentate and carried to vein 3, where 

 it reaches the greatest outward bend, thence more evenly to the inner 

 margin. The s. t. space is more or less completely dark-filled ; some- 

 times entirely, so as to form a distinct band, sometimes only at costa 

 to form a dark triangular blotch, and sometimes the dark shading 

 extends inward into the median space. Usually the lower half of the 

 line is broader and more conspicuously contrasting. The terminal 

 area may be concolorous, which is the rule in the females; it may be 

 more or less powdered with bluish gray, forming an obscure band, 

 and that is more common in the males ; there may be a dusky shading
