dcr black line on the internal margin. Reniforin indicated by a row 

 of black dots anterior to the discal cross-vein ; orbicular only visible 

 as a central pale shade and four outer brown dots. Nerves and 

 nervules clothed with black scales; on the interspaces intermediately 

 are brown scales, with a white streak centrally, beneath which, on 

 the subierminal margin, are the usual black streaks in all the inter- 

 spaces, the most conspicuous of which is that in cell 4 (farther 

 removed from the margin than the others). Fringe white, cut with 

 brown on each side of the nervules, opposite the interspaceal lines of 

 brown scales ; these brown ciliary scales of each interspace joined by 

 a brown marginal line. 



Secondaries acute, excavated opposite the cell, slightly dentate; 

 white, hyaline. Nerves and nervules heavily marked with black 

 scales, especially toward the margin ; no distinct marginal border, 

 but in place thereof the extreme margin is brown, with some brown 

 scales extending a short distance therefrom, and farther in cells 1 h 

 and 4 ; some brown scales on the costal nervure apically. 



Beneath, primaries pale brown with an aeneous reflection ; a con" 

 spicuous brown spot on the discal cross-vein. Secondaries, with 

 brown scales on the nerves and nervules and marginally as above, 

 though less abundantly ; sprinkled with brown scales costally, and in 

 the cell above the fold ; cellular fold ana discal cross-vein above it 

 broadly covered with brown scales, diffuse on the latter, giving a 

 conspicuous cellular spot ; these features seen in transparency from 

 above 



Described from two (^ 's, differing materially in size; the larger 

 and better specimen, from which the features are mainly drawn 

 measures two inches expanse of wings, length of body .^Q in. ; the 

 other 1.70 in. expanse, length of body .72 in. 



In addition to disparity in size, the two examples differ somewhat 

 in shape of wings, those of the smaller being narrower and more 

 acute, to the degree that the male usually varies from the female in 

 the several species of this genus ; yet the two examples are undoubted 

 males, as is shown by their frenulum examination. In all other par- 

 ticulars, so far as they are traceable, the two are identical. They are 

 unfortunately in poor condition, and the description above given 

 may require correction.
