a median black line and usually a slightly darker shade below tip. 

 Thorax with three dusky brown transverse lines, the one behind the 

 middle often edged with blue-gray scales. Primaries with usually 

 a more or less mottled appearance; basal area darker as a rule and 

 the triangular costal area between t. p. and s. t., lines usually as dark 

 or darker than any other portion of the wing. Basal line usually 

 traceable, sometimes evident, geminate, in the male often picked 

 out by bluish white scales. T. a. line best emphasized by the differ- 

 ence in shade between basal and median space : rarely geminate, the 

 lines black edged, interval brown; often a pale line separates off a 

 narrow band from the rest of the basal space; in course inwardly 

 oblique, only a little irregular or outcurved. In the male there is 

 usually a pale blue edging beyond the line which may expand into a 

 rather broad fascia. Median space usually a little paler than the 

 rest of the wing, but it may be concolorous in either sex. As a rule 

 there are three transverse undulating dusky lines which tend to 

 darken the space a little at or before the middle, leaving the outer 

 portion paler; quite usually also there is a darker brown shade over 

 the costal area. T. p. line geminate, very fine, rarely black and then 

 tending to lose the outer portion; in course outwardly oblique to the 

 interspace between veins G and 7, there acutely bent, making a deep 

 incurve followed by an equal outcurve and then oblique, evenly 

 sinuate to the inner margin. S. t. line inwardly oblique from costa 

 to vein 5, then outcurved and parallel with the t. p. line for the bal- 

 ance of its course. From the costa to vein 7 it is edged with black 

 inwardly, and the space to the t. p. line is dark browui or even black- 

 ish ; to vein 4 the line is interrupted or feebly marked on the pale 

 ground, and below that point to the inner margin it is often black 

 and conspicuous. Over or beyond this line, especially in the female, 

 a dusky or blackish shade may extend from inner margin upward 

 to the angle of the line and then outward on or below vein 4 to the 

 outer margin, interrupting the terminal space and forming a break 

 for the pale median shade to extend outward to the margin. In the 

 male this shade may be powdered with bluish wdiite, or there may 

 be a lilac blue line, or the entire terminal area may be bluish, inter- 

 rupted always by the dark shading on or below vein 4. There is a 

 dusky terminal line which may be broken and partly lunulate and is 

 sometimes preceded by brown or bluish dots. The fringes are inter- 

 lined with pale at base and darker at middle. Orbicular a black or 

 brown dot which is often wanting. Reniform rather small, lunate, 

 dusky, without defining lines as a rule. Secondaries usually a little 

 paler basally, the disk crossed by a series of lighter and darker trans- 

 verse, somewhat undulated shade lines. A distinct, slightly incurved 

 and slightly irregular black line, outwardly pale edged, continues 

 the s. t. of primaries. The terminal space in the male is usually more
