finely, outside broadly edged with blackish-grey, on the outside the black colour on either side of the yellow 
veins is somewhat flown out towards the margin, so that a kind of denticulation may be produced; at the 
cell-end a tiny black dot may be present or also absent. Hindwing with a hardly noticeable trace of a light 
median line. In the $ the postmedian line may be reduced to an equally broad straight grey band crossed by 
the yellow veins. Antennae black. Colombia; Guiana. 
D. medinensis sp.n. (117 A a). Anterior body light ochreous, abdomen of a brighter orange, laterally 
black with white spots, tarsi and antennae black. Forewing ochreous, in the marginal area with slightly darker 
veins; antemedian line straight, broadly edged with white, finely with blackish; at the cross-vein a darker spot; 
posterior transverse line distantly remote from the margin, quite straight, broad white, outside very narrowly 
bordered with brownish ochreous, at the inner margin almost united with the anterior line; in the broad marginal 
area an irregularly undulated whitish subterminal line is distinctly visible. Hindwing somewhat lighter than 
forewing. Type: 1 9 from Medina (Eastern Colombia) in the Coll. Bang-Haas. 
D. obliqua Bouv. (117 A a). Forewing light reddish yellow, often with fine darker veins, dusted with 
brown or grey, particularly behind the antemedian line, cross-vein, and subterminally, and a little before the 
margin; anterior transverse line short, convex, below the median vein and on 1 almost angular, black, crossed 
by 2 yellow veins, the basal area lighter; cross-vein dark, in the middle strongly introangular; posterior trans¬ 
verse line characterized by its oblique course, at the costal margin much nearer to the apex than at the inner 
margin to the tornus, little white, outside intensely black, traversed by orange and almost undulate-dentate. 
Hindwing generally still darker than the subterminal area of the forewing. Abdomen orange, with narrow black 
rings, laterally black with white spots. Peru; Bolivia. 
D. gregatus Bouv. is known to me only from the description and figure. It is said to be closely allied 
to peruvianus ; more dingy grey above a pink ground-colour, the veins scarcely darker; anterior transverse line 
inside at the inner margin with small black spots; posterior transverse line inside and outside bordered with 
black, only narrowly traversed by yellowish, with a very narrow white costal-marginal spot. Shape of wings 
shorter and broader than in the other species. Venezuela. Larvae in an oval bag of 15 to 20 cm length, light 
grey, with both ends open, fastened with a stalk at the end of a branch by using neighbouring leaves. The bag 
contains 10 to 12 cocoons. Larva itself green with stellately arranged tufts of red-brown thorns with black 
tips. It lives on “Mamon”. 
D. bireniis sp.n. (117 A a) is a large species. Thorax blackish-brown, abdomen orange with broad 
velvety black rings, ventrum black, laterally with white spots, anus rusty red. Forewing dark brown, with 
black veins; antemedian line broad white, outside broadly inside feebly bordered with black, traversed by 3 
yellow veins, the cross-vein is a black angle; posterior transverse line slightly curved, white, on both sides very 
broadly bordered with black and broadly traversed by orange vein-rays of 6 to 8 mm length; subterminal line 
marked by the contrast with the lighter marginal area, receding between 4 and 5 as far as the postmedian line; 
fringe rusty brown, hindwing with a faded, slightly darker postmedian shadowy band. According to 2 
type from Sa. Catharina in the Coll. W. Hopp, Charlottenburg, another specimen from Macas (Ecuador) in 
the Coll. Niepelt. 
B. albosignatus Bouv. was not before me. Forewing smoke-brown, somewhat lighter than in infuscatus, 
with scarcely darker veins; cross-vein and discal spot feebly flawed a little above the centre, before it a white 
spot; anterior transverse line somewhat zigzag-shaped, rather indistinct; postmeclian line parallel to the distal 
margin, somewhat more convex than the latter, almost quite black, without any white, the yellow traversing 
veins very feeble; it cuts vein 4 behind its middle; the undulate subterminal line is quite indistinct. Described 
from Venezuela. 
D. niceros Dogn. (117 D e). Forewing black with a chestnut-brown reflection and 2 white transverse 
lines, the first extending from the base of the costal margin obliquely distad and being interrupted below the 
median vein and at the inner margin; the posterior line is parallel to the margin, subterminal, interrupted by 
the veins and vanishing towards the apex. Hindwing as fore wing with the continuation of the subterminal 
line which is here distinct and not interrupted by the veins, extending to the inner margin; the black thorax 
is intermixed with ochreous hairs; abdomen black with yellow rings, with a lateral row of white dots. Northern 
Peru (Huancabamba). 
D. albilinea Schs. (103 A b). Head and thorax light brown, abdomen above ochreous, beneath light 
brown, with a lateral row of black, blue-centred spots. Forewing light brown, with fine ochreous veins, with 
a white diffuse spot in the cell; from the base of the costal margin an oblique dark line extends to the inner 
margin, being interrupted below the cell by a broad white stripe which extends from the base almost to the 
margin where it meets a white, darker brown-edged stripe proceeding from the costal margin from near the 
apex. Hindwing with a very feeble whitish distal band. Goyas, Brazil. 
VII. albata-group. 
D. albata n. sp. ( Maass. i. 1.) (117 A a ). A very peculiar insect. Head and prothorax ochreous, palpi 
black, antennae smoky brown; the absent abdomen (a wrong one has been glued on the type) is presumably
