ous and brighter in the male. T. a. line black, a little curved, irreg- 

 ular on the cell, as a whole inwardly oblique. In the male this line is 

 followed by a belt of bluish scales which are quite conspicuous; in 

 the female there is a similar band, but the scales are more scattering, 

 of a duller tint, and over a much darker ground, so that they are not 

 relieved. A punctiform black orbicular may or may not be included 

 in this band. Two undulating dusky lines cross before the middle 

 and aid in darkening that area; a third and sometimes a fourth arc 

 more obscure and cross beyond the middle, which is the palest por- 

 tion of the wing. The reniform is narrow, upright, a little darker, 

 anteriorly marked by black and posteriorly by white scales; both of 

 these distinctions more obvious in the female. T. p. line black, slen- 

 der, continuous, outwardly edged by yellow scales in some females, 

 irregular, in general outwardly oblique from costa to near middle, 

 then with a rounded angle bent inwardly and oblique to the inner 

 margin. S. t. line broader, more diffuse, tending to become broken 

 on the veins by bluish dots, parallel to but w T ell removed from t. p. 

 line to vein T, where it diverges and runs outwardly oblique to the 

 costa. The space between these lines is darker than the median 

 space, and the s. t. line is followed by a broad band which in the 

 male is as dark and in the female much darker than the included 

 shade. Beyond this band is a paler brown shade which in the male is 

 blue powdered, and in the female is strigillate with darker brown. 

 Outwardly there is a darker brown marginal shade, broken by pale 

 lunules at the incisions. The fringes have a yellowish Hue at base 

 and are strigillate with brown. Secondaries pale brown to the mid- 

 dle, then with two or three more or less obvious, somewhat diffuse 

 transverse lines before the double, black, extra-median line, the inner 

 portion of which is narrow, thread-like, even; the outer edged with 

 yellow scales, and forming a small 5> near the upper part of its 

 course. Beyond this is a much darker band in the female, and in the 

 male a blue powdering. The terminal area and fringes are as in the 

 primaries. Beneath brown, powdery, all wings with a discal spot and 

 an extra-median brown line, secondaries sometimes with two lines 

 within and one or two beyond this line. A series of whitish dots at 

 the incisions on both wings.

The color contrast between the sexes is very strongly marked in this 

 species and yet there is less difference in the actual amount of bine 

 powdering than occurs in some other species. In the female the blue
