costal margin, apex, and distal margin. Thorax violettish-grey, the collar with intermixed greenish hairs, 
abdomen yellowish-grey. Mexico City. — cinescens /. n. is the greyer form, from Zacualpan, in February and 
March. Types <$% in the Coll. Draudt. 
D. cerriben Dyar (148 k) is bluish ash-grey, slightly dusted at the inner-marginal area, with a black 
basal ray and a black dot in the lower cell-angle, surrounded by brownish-grey dusting; the anterior transverse 
line is entirely absent, the posterior one is very oblique at the costal margin and then marked doubly at the 
inner margin, quadrupled here by black strigiform spots before and behind it, a white subanal streak edged 
with black inside is above it; subapical black streaks are at the costal margin, small less distinct internerval 
spots below them seem to be removed a little farther towards the margin. Hindwing white with a black inner- 
angular spot. Mexico (Zacualpan). 
D. indepta sp. n. (148 k) is allied to cerriben, but much larger and darker grey, besides the basal streak 
also the median vein is finely black, and the discal dot is not in the lower cell-angle, but close below the origin 
of vein 5; the posterior transverse line is distinct and double not only at the costal and inner margins, but in 
its whole course, filled with light, and behind it, above and below the median radial branch, a blackish-brown 
stripe extends to the margin; the white subanal spot is broader and whiter. The white hindwing is broadly 
smoked at the costal margin. Mexico (Zacualpan, in September); type: $ in the Coll. Draudt. 
D. vallima Schs. (148 k) has light brownish forewings dusted with greenish and reddish at the costal 
margin, the veins in the distal part strewn with black and white, the beginnings of the transverse lines at the 
costal margin marked by darker spots, besides only the double posterior line marked behind the cell; a greenish 
spot mixed with lilac before the dark cell-end streak is situate in the cell; the distal margin is broad darker 
brown, with dark velvety brown internerval streaks subapically and above the anal angle, the latter streak 
followed by a white streak; the light brown fringe is speckled darker on the ends of the veins. Hindwing 
diaphanous violettish-brown, dusted darker brown at the margin. French Guiana. Expanse of wings: <$ 36, 
$ 42 mm. 
D. patula Schs. is somewhat like muelleri, but considerably larger, forewing violettish-grey'in the basal 
half and along the submedian vein to the margin, light brownish olive below the cell and apically, with a 
dark brown basal ray and discal streak, shaded with brown behind the latter; a fine interrupted brown post¬ 
median line is in a broad reddish-yellow shadowy stripe which extends from the costal margin to the lower 
median branch; vein 5 is broadly bordered with dark brown on both sides as far as the margin, a brown subanal 
spot encloses a light wedge. Hindwing white, brownish at the inner margin and the veins. Expanse of wings: 
41 mm. Costa Rica. 
D. obligata Dyar (149 a) is also similar to muelleri and as large as patula. Forewing grey, densely dusted 
with black in the basal two thirds, the cell-end streak in an oval light spot, with a brown internerval streak 
behind it between the veins 4 and 5; the light postmedian line is almost straight; apex light grey; the veins 
are striped black towards the margin and thickened on the fringe. Hindwing white with darker veins, narrowly 
grey at the costal and distal margins, with a blackish anal-angular spot. Mexico (Zacualpan). 
D, marimba Schs. has brownish-grey forewings, darker at the base of the costal margin and in the cell, 
the veins strewn with black and white, with a light olive tint in the distal half of the cell and below it, fine 
double darker transverse lines, the posterior one dentate, the distal portion punctiform in the lower half; a 
brown, white-edged line is at the cross-vein, a dark brown stripe behind it extends to the postmedian line between 
the veins 4 and 5; small dark spots in the darkened distal-marginal part are behind a marked undulate line, 
white dots above and below vein 2 at the anal angle. Hindwing scantily scaled, white, with darker veins and 
marginal line, as well as a dark inner-angular spot and a chalky white spot above it. The $ shows the small 
dark marginal spots distally bordered with light, and a smoky margin of the hindwing. Expanse of wings: 
36 mm. Guatemala, Costa Rica. >c - 
D. limosa Schs. Eorewing blackish, strewn with light grey along the costal margin and at the apex, the 
transverse lines entirely covered by the ground-colour, only the undulate line is somewhat more distinct; a 
short black postcellular longitudinal streak. Hindwing white, smoked at the margins, a large blackish spot at 
the anal angle. Expanse of wings: 48 mm. A large species, described from a single $, from Rio de Janeiro. 
D. limosoides Schs. (= claricostata Dogn.) (149 a) is very similar to limosa, forewing dark brown, apex 
and cell lighter, dusted with yellowish and olive green, with a large olive green spot bordered with white at the 
cell-end; the double dentate indistinct posterior transverse line is partly broken up into vein-dots, small oblong 
dark subterminal spots are edged with white outside at the costal margin and anal angle, the ends of the veins 
speckled black. Hindwing white with brownish veins and marginal line, as well as an apical and anal-angular 
spot. Expanse of wings: 39 mm. Costa Rica, French Guiana. 
D. fechima Schs. is allied to limosoides from which it differs in the more red-brown colour, head and 
thorax being cinnamon and chestnut brown, abdomen brown, the base and the last two segments reddish 
cinnamon. Eorewing cinnamon brown in the basal and inner-marginal areas, black above it as far as the post-
