D. unibrata Wkr. (= athereo Harr.) is considerably larger than the preceding species, but of the 
same scheme of markings. Forewing light ash-grey with an olive green tinge and a blackish curved shadow 
before the discal streak, extending as in subrotata beyond the anal angle, the ground-colour behind and below 
it being lightest; transverse lines and submarginal line as in lunata, the latter line broad, distinctly interrupted 
on vein 4, almost extinct at the costal and inner margins; fringe speckled dark at the ends of the veins. Hindwing 
slightly smoky in both sexes, darker at the margin with a distinct white postmedian line. — Larva thickened 
on the median segments, with two coniform tubercles behind the head, green, with 2 long dorsal spots which 
are filled with orange and bordered with purple brown, only interrupted on the 7th segment. It lives on 
oaks. Distributed from Pennsylvania, New York, Illinois to Florida. — f. pulverea Grt. & Rob. (150 c) 
differs in the entire absence of the olive green tinge, but it is more intensely strewn with black; the large light 
subapical crescentiform spot spotted red-brown is much more thickly bordered with black inwards, the fringe 
much more contrastingly speckled black and light. — f. averna B. <b McD. (= pasathelys Dyar) is blackish- 
brown on the forewing, mixed with lighter and without any olive tinge, the light spot behind the cell darkened 
brown, the black submarginal line very strong, hindwing of a purer white colour, smoky only at the margin. 
Arizona, Mexico. 
D. incongrua B. <£• Benj. Fore wing olive grey, mixed with red-brown and green, strewn with black 
on the veins, with a black basal ray and more or less faded double black transverse lines, the submarginal line 
represented by black internerval sagittae similarly as in the preceding species; the black crescentiform cell-end 
streak is distinctly surrounded with red-brown. Hindwing white, strewn with blackish on the veins and margin. 
New Mexico, Arizona. 
D. cubana Grt. (150 d) is allied to vaxia and, at the same time, forms the transition to the next 
group; it differs from varia in the entire absence of the white subapical blotch, the postmedian line extending 
much more irregularly, and a distinct median line forming a sharp, almost right angle distally above the inner 
margin; the submarginal line is broken up into single internerval streaks, and the marginal line is fine, black. 
Hindwing of a pure white, whith a small black anal spot and somewhat smoky costal margin. Cuba and 
Florida. 
D. daona Drc. (= androdora Dyar) (150 d) as well as the two following species are probably hardly 
separable specifically from cubana', according to Dyar it merely differs in the postmedian line being less dark 
and more faded. Forewing light whitish-grey, lightest in the median area, densely dusted with brownish-grey; 
the rather indistinct double antemedian line extends deep black above the inner margin as an arcuate line 
back almost to the base; behind the fine black discal lunular streak there is a greyish-black lunular spot 
filled with yellowish-white below, traversed by long fine black internerval streaks and bordered below by 
a jet-black arcuate line; this large dark spot is almost obsolete in the apparently rare <$. Hindwing white, 
slightly scaled, smoky at the costal margin, with a small anal blotch. Mexico. — f. n. suavis (150 cl) I denominate 
a distinctly separable constant race from Colima, which is smaller and of a much softer bluish-grey colouring, 
intensely mixed with rust-brown basally and postmedianly, especially in the surroundings of the transverse 
lines; the ultracellular lunular spot is not filled with yellowish-white below, but with rust-brown; all the black 
lines are much finer. 
D. clitiusa Schs. is very similar to daona, but larger and much lighter, the subterminal line less distinct 
and the line above vein 2 straighter. Ground-colour light sand-coloured, partly mixed with reddish-brown, 
the lines otherwise as in daona', the feeble whitish subterminal line is bordered with black inside between 8 
and 6 and has a small black spot above 3. Hindwing white, costal margin sand-coloured, with 3 dark apical 
lines, the inner margin also light brownish-grey. Expanse of wings: 45 mm. Brazil (Joinville). 
D. aroensis Schs. Fore wing grey, with a yellowish tinge at the inner margin and distal margin and below 
the median vein, with fine black-striped veins and single internerval stripes; transverse line and median line 
rather indistinct, the latter undulate, the posterior transverse line only irregularly marked by single black 
scales, grey shading behind the cell and subapically. The $ is of a purer silvery grey without the yellowish tinge, 
without transverse lines and subterminally more intensely dusted with brown. Hindwing white, smoky at 
the costal and inner margins, darkened in the $ with a brownish-grey margin. Expanse of wings: $ 38, 
$ 46 mm. Venezuela. 
D. gelduba Schs. (150 d) is allied to the preceding species, but it has shorter broader forewings; it 
is wrong to range it under Rifargia, for the apparently rare seems not yet to have been known hitherto; 
it is, however, before me and has shortly pectinated antennae; forewing brownish-grey, intensely mixed 
with olive green, with a fine black basal ray, indistinct single transverse lines more or less distinctly bordered 
with red-brown, and a discal crescentiform streak, before which a brown arcuate shadow extends to the margin 
above the anal angle; blackish-grey marginal shading in the upper half of the wing extends in an acute angle 
on the lowest radial branch to the cross-vein and contains 4 jet-black oblique internerval streaks subapically. 
Hindwing white, slightly smoky at the costal and inner margins, brownish-grey in the $. The $ is without 
the brown arcuate shadow to the anal angle, the subapical marginal shading is very indistinct. Mexico.
