PARAETHRIA; AETHRIOPSIS; ARGYROEIDES. By Dr. M. Draudt. 
rubipectus. A. rubipectus Schcius (18 k) is likewise dissimilar to the other species, above black, on the thorax 
and abdomen a blue lustre; anterior side of the palpi, forehead, neck and borders of the shoulder-covers are 
white; chest and hips carmine. The hyaline wings exhibit narrow black margins. Hayti. 
67. Genus: Paraethria Hmps. 
The abdomen is not strangulated, does not exhibit any lateral hair-tufts at tlie end, but it is above 
roughly haired at the base. On the forewings the median veins are on a common petiole, the middle radial 
vein rises above the lower cell-angle. On the hindwing with a long cell the subcostal and 1st radial vein rise 
petioled, all the others separately. 
angusti- P. angustipennis Rothsch. (19 a) and the following species have somewhat stunted hindwings. The 
pennis. body is black, the palpi are entirely white; the abdomen shows at the sides of the 3rd segment a small whitish 
spot. From the Amazon. 
mapiria. P. niapiria spec. nov. (18 k) is perhaps only a form of the preceding, at any rate it is very near to 
it. The body is above metallic bluishgreen, also the legs, otherwise below black. The palpi are black, only 
at the anterior side white like the forehead. The abdomen exhibits above on the 3 first rings a white longitudinal 
stripe, at. the sides of the same segments a very large, yellowish-white spot being connected across the ventral 
side with that of the other side. Described according to a female from Bolivia (Mapiri); from Bang-Haas. 
triseriata. A. triseriata H.-Schdff. (18 k) is black with white dots on the thorax and abdomen. Characteristic are 
the hindwings being black with a basal hyaline spot below the cell; the forewings are hyaline with broad black 
margins; the middle radial vein is more intensely black than the others. Found from Brazil as far as Argentina, 
in day-time on compositae. 
flavo- P. flavosignata Rothscli. (19 a) differs from triseriata by the orange-banded segments 2 to 6 of the 
signata. abdomen and by the thorax being spotted and striped orange-yellow; head, palpi, and forehips are orange, 
the legs brown, the antennae black. The two last abdominal rings are spotted scarlet. On the yellowish hyaline 
wings the black margins, particularly at the proximal margin, profusely powdered with brownish scales. Bolivia. 
68. Genus: Aetliriopsis Btlr. 
Veins of hindwings like in the preceding genus. On the forewings the. median veins and the lower radial 
vein rise widely separated, the upper radial rises below the upper cell-angle. The palpi are longer than in 
Paraethria. 
barbata. A. barbata Schrottky. Body black; forehead, posterior margins of the eyes, spots on the collar and 
stripes on the shoulder-covers white. Chest anteriorly with rosy red hair, laterally spotted white; anterior 
and posterior hips, as well as the apices of the posterior femora white. Abdomen with lateral white spots, under¬ 
neath in the middle white. Wings hyaline with black veins and discal spot, beginning from which the costal 
margin, as well as the distal and proximal margin are broadly bordered with black. Hindwings opaline-white, 
at the costal margin yellowish, below it black. Expanse of wings: 28 mm. Paraguay. 
69. Genus: Argyroeides Btlr. 
Easily recognizable by the long, slender abdomen, the 2nd segment being strangulated, and with hail- 
tufts at the end. The entirely hyaline forewings are broad, the hindwings narrow, the proximal margin is formed 
by a small lobe covered with hair. The upper median vein of the forewing rises below the cell-angle, the 1st 
subcostal vein from the cell. 
strigula. A. strigula Druce (19 a) has the shoulder-covers and abdominal rings bordered with orange-red; a 
spot on the metathorax and the strangulated 2nd segment are yellowish-white; forehead and vertex blue; the 
second joints of the palpi, bases of antennae, spots on shoulders and hips are white; venter banded yellowish- 
white. The wings are faintly yellowish hyaline with narrow black margins. Brazil (Sao Paulo). 
flavicornis. A. flavicornis Rothsch. (19 a) is one of the larger species, recognizable by the orange-yellow antennae. 
Body black; palpi and 2 spots between the eyes golden yellow, the proximal margin of the shoulder-covers 
orange-haired; the abdomen is suffused with blue and exhibits on each side of the first ring a yellow spot; 
forehips white, middle and posterior hips cream-coloured, ends of tibiae orange-yellow, the legs otherwise brown. 
The wings are yellowish hyaline, veins, costal and proximal margins orange, distal margins narrowly black. 
Amazon (Teffe).
