Fig. C. Eurocilia. The two surfaces of the wings are not different in colour or
in pattern. The body is yellow beneath; the antennae are plumose, and the
proboscis is curled. It is from the West Indies, and is in the last-mentioned
collection.

P. eurocilia Cr. (= zerbina Stoll.) (64 a). Forewing blackish-brown, in the
basal half more or less lighter, with a narrow brimstone-coloured discal band
and subapical band which are so close together that they are confluent before
and behind the cell and thus enclose the blackish-brown spot on the transverse
vein. The posterior band may be shortened. White submarginal spots absent or
present. Hindwing as in bivittata, the extent of the black markings very
variable. Body also like in bivittata. -- In obscurata form. nov. the whole
basal part of the forewing is fused with the bands which are here densely dusted
with brownish, there only remains a blackish spot in the centre of the cell;
hindwing black, only the costa, a posteriorly narrowed submarginal band from the
costa to about 1/2 of the distal margin, the upper part of the cell, distally
and basally prolonged, are red-brown (female from the Chanchamayo in the Berlin
Museum). -- melaina form. nov. is quite blackish, only the bands in the forewing
brimstone-coloured, the red-brown markings marked with a violettish grey (female
from Tachira, Venezuela, in the Tring Museum). Colombia, Amazons, Guiana,
Ecuador, Peru, Bolivia.

The bivittata paragraph referred to (same work, p. 443, pl. 64 a):

P. bivittata Wkr. (= disjuncta Wkr.) (64 a). In the habitus recalling P. aorsa
(64 a) and recta (63 g), wings more longish, underside of abdomen without the
black median line. Discal band and subapical band of forewing broad, yellow,
both nearing each other, rarely narrow. Hindwing red-brown, with a black margin
dotted bluish-white, and a black transverse band before it. The veins between
both, and the transverse vein black. Postdiscal band and white submarginal spots
may disappear. Venezuela, Panama.

Redescription
Male (Fig. 28 A).
Head: predominantly brown. Vertex with white scales in the anterior and
posterior region of the scape, spots with reduced tufts of white scales in the
region behind the ocelli. Labial palpus brown, anterior region of the 1st and
2nd segments with white scales.
Thorax: predominantly brown. Prothoracic collar with four yellow spots,
sometimes close together or partly fused. Tegula with two basal spots, one on
the inner margin, white, sometimes yellowish, and another, yellow, extending to
the central part of the tegula. Mesothorax with a tuft of white scales in the
antero-medial region. Fore wing with costal, outer and inner margins brown,
veins outlined with brown scales; three semi-hyaline patches with brown scales,
not delimited and sometimes fused in some individuals: (i) triangular in the
basal region, (ii) subrectangular in the median region, (iii) oval in the
subapical region, between R5 and CuA1; two brown bands, one between the costal
and inner margins, passing through the middle of the discal cell, sometimes
fading from the stem of CuA onwards, and another between the costal and outer
margins, passing through the closure of the discal cell, sometimes fading beyond
M3; white dots in the submarginal region, obscured in some individuals; two
spots at the wing base, one with reddish scales on the stem of R and another
with white scales on the stem of CuA; underside with a pattern like the
upperside, but the wing base with a reddish spot in the costal region. Hind wing
with costal and outer margins brown, median region of variable colour,
yellowish, orange or reddish; a band at the closure of the discal cell and the
stem of CuA outlined with brown scales; submarginal band brown, with its
proximal element formed by chamfered red spots, obscured in some individuals,
and its distal element formed by small white spots; underside with a pattern
like the upperside, but with the costal margin orange, the proximal element of
the submarginal band more evident and the wing base with a reddish spot in the
costal region.
Abdomen: dorsally brown, with lateral yellow spots on A1-A8, sometimes orange;
ventrally yellow. Tufts of orange scales on the terminal part of the abdomen.
Genitalia (Fig. 41): tegumen trapezoidal in dorsal view, anterior margin sinuous
and with postero-lateral projections with rounded apex. Uncus bifid, not fused
to the tegumen; antero-lateral region of the uncus with a ventral projection,
narrower than the arms of the uncus; arms of the uncus parallel, twice as wide
as the antero-lateral projection, fused in their anterior part, not projected
ventrally and with dentate apex. Valva entire; medial apodeme (lacinia) absent,
distal apodeme absent; sacculus distinct, in the form of a fold; harpe
indistinct; cucullus reduced to a small protuberance, not extending beyond the
valvula; valvula sclerotized and digitiform and extended posteriorly. Transtilla
sclerotized, not articulated with the valva and fused to the juxta. Juxta
sclerotized, two subquadrate sclerites. Saccus with vestigial or reduced
anterior projections. Aedeagus straight, smooth; ejaculatory bulb rounded,
foramen lateral; vesica with one lobe, cornutus in the form of microspines in
the central part of the vesica, everted part of the ejaculatory duct smooth.
Female (Fig. 28 B).
Head: predominantly brown. Frontoclypeus with white scales near the labrum.
Vertex brown, anterior and posterior region of the scape with white scales,
spots with reduced tufts of white scales in the region behind the ocelli. Labial
palpus brown, anterior region of the 1st and 2nd segments with white scales.
Thorax: predominantly brown. Prothoracic collar with four yellow spots. Tegula
like that of the male. Mesothorax with a tuft of white scales in the
antero-medial region. Fore wing brown; basal region variable, generally light
brown, which may have yellowish tones extending to the median region and merging
with the discal band in some individuals; discal band yellow, oblique, from the
costal margin to the region of the tornus, passing through the subterminal
region of the discal cell, sometimes obscured beyond CuA2; oblique postdiscal
band yellow, from the costal margin towards the outer margin, generally as far
as CuA1, sometimes absent, sometimes fused with the discal band near the costal
margin and at CuA1; a brown spot at the closure of the discal cell, visible when
the postdiscal band is present; outer margin with white submarginal dots,
sometimes obscured; underside with a pattern like the upperside, but with orange
tones more evident in the basal part of the wing and the reddish spot in the
costal region masked by the similar ground tone. Hind wing with the outer margin
brown, basal region generally orange; discal band dark brown, from M1 to the
inner margin, of variable width, which may make the wing completely dark brown
in melanic individuals; submarginal band brown, its proximal element in the form
of chamfered orange spots, better outlined in melanic individuals, its distal
element in the form of white dots along the outer margin; underside with a
pattern like the upperside, but with the costal margin orange.
Abdomen: dorsally brown, with two lateral bands, orange and evident on A1-A5,
yellow and reduced on A6 to A8; ventrally yellow. Tufts of orange scales on the
terminal part of the abdomen.
Genitalia: seventh sternite with pockets lateral to the ostium, symmetrical,
sclerotized; ostium sclerotized, fused to the seventh sternite, extended
posteriorly, with two dorsal projections, flattened dorso-ventrally, separated
and with convex apex; antrum sclerotized, displaced to the right; ductus bursae
sclerotized, short; corpus bursae not extending beyond the seventh sternite,
signa present. Lamella antevaginalis absent; lamella postvaginalis absent.
