the margin more brownish, at the base with brighter red hair; discal dot and a curved median line dark brown, 
behind it a rosy-reddish area and a broad dark brown distal band. The $ shows 2 distinct dark brown transverse 
lines, the anterior one subcostally angled, inside bordered with whitish, between them a feeble brown discal 
dot. Hindwing lighter red than in the the bands faded and nearer to the margin. Abdomen ochreous brown 
with black abdominal belts and long white hairs. Expanse of wings: <$ 90, $ 115 mm. Patria unknown. 
D. ursina Wkr. (117 Bb). Forewing on the yellowish-brown ground densely and finely strewn with a ursina. 
darker brown, the small oblique basal area dark brown, 2 transverse lines somewhat convergent towards the 
inner margin are fine dark brown, very feebly denticulate, in the narrow median area at the upper cell-angle 
a small white spot, a/t the lower one a small black spot in a whitish ring; marginal area somewhat lighter 
towards the subterminal area, receding between 4 and 6, below it once more in 2 short bows. Hindwing 
generally towards the base darker, with 2 nebulous bands in the lighter marginal area and a small faint discal 
spot. Abdomen above black with narrow reddish-brown rings. Brazil. 
D. avicula sp. n. (117 B b) is somewhat allied to ursina. Ground-colour varying between light brownish- avicula. 
grey and light red-brown, very finely strewn darker, the median band prominently darker, still darker than 
the broad subterminal shadow behind it; the anterior transverse line is flawed in an obtuse angle, the exterior 
line almost straight, very slightly curved S-like, in the upper half convex towards the margin, in the lower 
half towards the base, both on the averted sides more or less bordered with whitish; in the upper cell-angle 
a small white spot which may also be absent, in the lower one a black spot; subterminal shadow as in ursina 
in contrast with the likewise somewhat similar curitiba. Hindwing more scantily scaled greyish-brown, at the 
base with reddish flesh-coloured hairs; discal spot quite indistinct, the two anteterminal lines as in ursina , 
marginal area like the forewing slightly strewn. Thorax blackish-brown, abdomen above quite black, beneath brown, 
anus bright brownish-red. Described from 3 1 $. ^ type from Paraguay bred from a not described larva 
on Rapanea laetevirens; $ type from Sao Paulo, both in the Berlin Museum; co-type 1 very large contrasting 
S from the Rio Songo, Bolivia, a third more red-brown <$ from Brazil, the exact habitat not being mentioned. 
D. parallela Sells-. (118 e) is ochreous grey on the forewing, darkest in the marginal third, with blackish- -parallela. 
brown thick parallel transverse lines; the posterior line very indistinct, feebly bent at the costal margin; discal 
dot black; the subterminal line is an irregular narrow brownish-grey shadow. Hindwing greyish-brown, dusted 
darker with a broad black postmedian line and an indistinct subterminal shadow, at the base with some 
ochreous hairs. The brownish-grey forewing exhibits beneath a feeble dark shadow from the apex obliquely 
to % inner margin. Anterior body brownish-grey, abdomen black with orange segmental lines. Expanse of 
wings: 105 mm. South-Eastern Brazil (Joinville). The species in mv opinion is much more allied to hircia, 
especially its form arcaei ; I have left it here merely on account of the neuration (6 and 7 of fore wing from 
the same place) of the only specimen at hand. 
D. quaesita sp. n. (118 e) is more like the hircia- group, but according to the neuration it belongs also to quaesiia. 
this group here. Anterior body blackish-brown, abdomen orange with black rings; forewing blackish-brown, 
scantily strewn with bluish-white hair-scales which are somewhat condensed on the proximal sides of both the 
thick black transverse lines; on the lower discocellular a thick black spot; subterminal line likewise marked by 
more densely strewn bluish-white scales, behind it clouded darker blackish-brown. Hindwing more scantily scaled, 
not strewn, with a thick black discal spot and a black subterminal line; fringe white. Type: 1 $ from the Rio 
Jacula near Rio Patia (Colombia) in the Coll. Hopp, Charlottenburg. 
IX. somniculosa-group (Plateia Hbn.). 
D. somniculosa Cr. (117 B b, c). A very large and unmistakable species. red-brown with 2 lilac white somnicu- 
transverse lines which are slightly convergent towards the inner margin, the anterior one subcostally inwards losa 
interrupted, and obtusely angled on the median vein; in the marginal area besides with 2 broad indistinct 
light nebulous bands; hindwing scarcely lighter, with or without a discal spot, with a light subterminal band. 
Thorax dark red-brown, metathorax and base of abdomen red-haired, abdomen black with orange rings. $ 
usually darker and very large, expanse of wings as wide as 140 mm. Guiana; Venezuela; Colombia. 
D. theobromana sp. n. (117 B c) is a transition to the following species; anterior body dark red-brown, theobroma- 
abdomen orange, above with black belts. Forewing chocolate brown, basally and subterminally strewn with na 
white, the short oblique basal area is coloured like the thorax and outside bordered with whitish; both the 
transverse lines are indistinctly darker, on the averted sides bordered with lilac whitish, the anterior line 
subcostally and on 1 angled in a basally open angle, the posterior line feebly dentate inwards on the veins, 
towards the costal margin indistinctly widened; subterminal line of the same shape as in panamensis. Hindwing 
sdarcely marked except 2 very indistinct anteterminal shadows between which the ground is somewhat lighter 
lilac whitish. Type: 1 9 Rom Villavicencio (Eastern Colombia) in the Coll. Bang-Haas. A similar, somewhat 
smaller $ from Southern Colombia, Mocoa, e Coll. Niepelt.
