distinct maculation. Primaries with all the markings fairly evident. As 

 a whole, the wing is darker from the base to a little beyond the middle ; 

 then a variably distinct pale gray or even whitish shading extends to the 

 s. t. line, the terminal spaces being again dark. There is a variable 

 amount of red in the dark colouring of the wing, and sometimes the 

 median space is quite distinctly reddish. Basal line geminate, black, not 

 very well defined. T. a. line geminate, black, the included space marked 

 by white scales, as a whole forming a rather even outcurve and only a 

 little irregular between the veins. The extreme base may be a little 

 lighter than the rest of the basal space. T. p. line geminate, brown, 

 usually not very distinct for the upper portion of its course, because it 

 passes through the pale space already described. It makes a wide out- 

 curve over the reniform and a correspondingly deep incurve undef the 

 cell. The s. t. line is distinct, emphasized by the difference in shade 

 between the dark terminal and the paler preceding space ; and it is also 

 emphasized by a dusky shading which precedes it, and thus shows that it 

 has three rather even and equal outcurves. There is a black terminal line, 

 followed by a yellowish line at the base of the dull brown fringes ; the 

 outer margin just a little irregular. There is a trace of a median shade on 

 the costa extending between the ordinary spots to the median vein ; but 

 not traceable below that point. The claviform is moderate in size, extends 

 half way across the median space, is outlined by black scales, filled with 

 the ground colour of the wmg and followed by a reddish blotch. Or- 

 bicular moderate in size, a little oblique, outlined by black scales and 

 hardly paler than the rest of the wing. Reniform large, broad, hardly 

 kidney-shaped, and yet less indented inwardly than at the outer side ; 

 usually of the palest colour of the wing. The veins through the pale 

 part of the wing are usually marked by blackish scales. Secondaries an 

 even smoky gray ; fringes a little paler and with a yellowish line at the 

 base. Beneath, powdery gray ; the secondaries with a more or less 

 obvious discal dot and powdery outer line. In some specimens the 

 primaries also show a trace of this line, and in others neither of the 

 wings have any markings whatever.

I have eight specimens under examination and have seen others, 

 most of them females. The latter are as a whole larger, the markings
