156 Psyche [Sept. -Dec. 
abdomen, and legs pale, unmarked; wings with greenish vena- 
tion, in fore wings the gradates wholly dark; some of the costals 
in middle, some branches of cubitus, the last few cubitals, and 
radials more or less, dark; in hind wings the gradates less 
plainly dark. 
The antennae shorter than wings; pronotum broader behind 
than long in middle, sides sloping toward front. 
Wings moderately broad, hind wings acute at tip; in fore 
wings five inner, seven outer gradates, in parallel rows, the inner 
much nearer to outer than outer row to margin, the inner row 
arising nearer to the last cubital cross-vein than to the penulti- 
mate. Costal area at widest not equal to radial area, the latter 
equal to the postcubital area, and this last about one and a half 
times broader than the cubital area; six cubital cross-veins 
beyond divisory cell, the latter ending beyond the cross-vein 
above; the third cubital cell as long as the second and a little 
broader; branches of radial sector but little bent at inner gra- 
dates; in hind wing two to three inner and five outer gradates, 
parallel and near each other. 
Length of fore wing 12 mm., width 4.3 mm.

and both gradate series bordered with dark, branches from 
radial sector and from cubitus mostly pale, marginal forkings 
dark; stigma pale yellowish. 
Wings rather narrow; fore wings almost and hind wings 
plainly acute at tips. In fore wings the costal area at broadest 
not nearly as broad as the radial area which is equal to the 
postcubital area, the latter one third broader than the cubital 
area; six cross-veins beyond the divisory cell, latter ends well 
beyond the cross-vein above; four or five inner, six outer gra- 
dates, outer parallel to outer margin, inner somewhat divergent 
from outer, last one or two of inner series nearer to outer than
