chestnut-brown lustre. Ventral valve brown, like the 3rd ventral segment margined by silvery white, at the 
2nd segment laterally an oblique white streak; the posterior margin of the 2 or 3 next ventral segments is orange- 
brownish. The ventral sides are intensely iridescent in a metallic blue. Legs orange-yellow, hips and ends of 
femora silvery-white, the femora inside and above dark brown. The faintly yellowish hyaline wings exhibit 
brown costal- and inner-marginal stripes, the apical third of the forewing is scaled in a greyish-brown down 
as far as the middle radial. A $ "from the Amazon (Bang-Haas) without the antennae; the antennae in the 
figure are restored. 
P. noverca Schaus (10 d) has a black body being covered with sparse, whitish-grey, small hairs which noverca. 
are somewhat denser on the forehead and at the collar. The antennae are black; the forehips are silvery white, 
the legs for the rest black except the under surface of the hind tibiae and-tarsi which are yellow-brownish. 
The basal two thirds of the costa and proximal margin of the hyaline forewings are jet-black, the cell thinly 
scaled in brown, which scaling gradually disappears towards the apex. In the submedian space, in the middle 
between the base and the rise of the lower median vein, there is a brownish oblique band. Common from August 
to November and from March to May on compositae in South Brazil, Paraguay and Argentina. 
P. jonesi Kaye. Head black, the eyes finely margined by white; the two basal thirds of the antennae jonesi. 
are purple-black, the thinner terminal third brownish. Abdomen above lustrous brown, beneath the segments 
are margined by yellow. Wings faintly yellowish-hyaline. Legs yellowish with darker femora. Expanse of 
wings: 20 mm. — Brazil (Santos) in March. 
P. exsul Rothsch. (10 d) the patria of which is uncertain, probably originating from Brazil (Rio de exsul. 
Janeiro or Sa. Catharina), is a small, jet-black species, only the legs are orange-brown. Ventral valve edged 
in grey. The diaphanous wings are orange-brownish in the basal two thirds, while the apical third is of a more 
greyish tinge. Costal and proximal margins brown. 
P. klagesi Rothsch. (10 d). Head black; collar orange-yellow; shoulder-covers striped in orange-yellow; klagesi. 
the brown thorax exhibits posteriorly a transverse yellow band. The first 3 abdominal segments are dark red- 
brown, the ot hers black. The legs are reddish-brown, the forehips and tibiae white; antennae black. The hyaline 
wings exhibit a dark-brown costal-marginal half and at the base a similar inner-marginal stripe. Venezuela 
(Caura River) in June. 
P. garleppi Rothsch. (10 d) is a somewhat larger species with a black body. Collar yellow, so are the garleppi. 
shoulder-covers which exhibit a black median stripe; metathorax with a yellow transverse stripe. Forehips 
and ventral valve white; anterior tibiae black, tarsi yellow; middle- and hind-hips black, tibiae and tarsi yellow. 
Antennae red-brown, at the tips yellow. The hyaline wings have narrow red-brown margins, the apex of the 
forewing, from the cell-end down to the middle radial, is brown. Described from Bolivia. 
P. aurifera Klages. Head and thorax dark-brown; antennae orange-brown, in the thickened part aurifera. 
with a purple reflection; both the last joints of the palpi, the forehead and head behind the eyes grey-haired, 
neck, collar and thorax covered with golden-yellow hairs. Legs orange-brown, forehips darker. Abdomen 
orange-brown, the 2nd segment laterally and below silvery-white, as well as the lateral spots and hind-margin 
at the 3rd segment. Wings yellowish hyaline with brown veins and fringes; forewings above the median and 
the middle radial vein dusted in brown, as well as the 2 basal inner-marginal thirds. This species with an 
expanse of 28 to 30 mm was described from Venezuela (Suapure), but it also occurs in Colombia. 
P. caurensis Klages (10 d). An easily recognizable, larger species. Head and thorax, antennae and caurensis. 
legs brownish orange-yellow, forehips silvery-white; the lower part of the forehead and the hind enclosure 
of the eyes white, the vertex exhibits a black spot. The 3 first abdominal rings brownish-orange, the rest of 
the abdomen black with a purple reflection. The first abdominal ring exhibits subdorsally black lines, the 
posterior half of the 4th is curled in yellow. The ventral valve and the 3rd ventral segment are margined by 
silvery white. The yellow-hyaline forewings are thinly scaled in yellow-brownish at the costal and proximal 
margins and outward of the discocellular as far as down to the middle radial; this part as well as the antennae, 
on being placed oblique to the light, show an amethystine reflection. Venezuela. 
P. steinbachi Rothsch. (10 e). Likewise a larger species greatly resembling the preceding. It differs steinbachi 
by its one-coloured golden-yellow head and orange-yellow forehips; the 2 first abdominal rings are chestnut- 
brown, the third one exhibits a black transverse band, the others are quite black (in caurensis the 4th shows 
yet a yellow hindmarginal ring). In Venezuela apparently not rare; known also from Bolivia. 
P. polistes Hhn. (= eumenicles Newm.) (10 e) has a one-coloured, reddish yellow-brown abdomen polistes. 
without any markings; the head and thorax are black and yellow marked. The wings are faintly yellowish 
hyaline, in the apical half down as far as the middle radial dusted in brownish. Widely distributed from Mexico 
through Guatemala, Venezuela as far as Brazil (Amazon, Para, Matto-Grosso). — In v. melanogen Dyar described metanogen 
from Mexico (State of Vera Cruz) the abdomen is black with yellow hindmargins of the segments, the yellow 
colour of the thorax is confined, too, and there occur transitions to the typical form, the black colour of the 
abdomen being brightened up to brown.
