498 PERISAMA. By J. Roper. 
lines between which there are 3 to 5 very small (sometimes missing) black dots. — Specimens with a brown 
under surface were described as hahneli Stgr. 
P. oppelii Latr. (102 Ae, f) from Colombia has a sulphur-yellow under surface with 2 black lines on 
the hindwings. In viridinota Bt/r. from Peru the blue band of the upper surface of the hindwings has disappeared 
except some few little scales. The 9 has somewhat rounder shape of the wings. 
P. eminens Oberth. has above a broad yellow band of the hindwings instead of the blue one, but does 
not differ from oppelii beneath. It is presumably not a species of its own, but only a remarkable aberration. 
P. comnena Hew. (102 Af) from Peru has an ochre-yellow-under surface of the hindwings and a large 
red basal spot of the forewings, thus resembling humboldtii, but between the black lines of the under surface of 
the hindwings there are no dots. 
P. xanthica Hew. (102 Af) from Peru has black upper surface of the hindwings and deePs yellow under 
surface with 2 nearly parallel black stripes. 
P. nyctimene Hew. (102 Af) from Ecuador has the forewings marked similarly as in humboldtiw, but 
on the distal margin of the hindwings only 4 sphenoidal blue spots, the under surface of the forewings being 
black with brown basal stripe and brown apex of the wings and 2 white spots at the costal margin; the 
under surface of the hindwings is yellowish-brown with a dentate submarginal line and a black, little curved 
median line between which there are 5 black dots and several submarginal white streaks. — In tristrigosa Btlr. 
from Peru the black dots on the under surface of the hindwings are absent. 
P. cloelia Hew. (= ochreipennis Btlr.) (102 Af) from Peru is most conspicuous by a large blue spot 
at the proximal margin of the forewings, which are besides provided with a blue basal stripe and a subapical 
spot; the hindwings have a faint blue band of the distal margin. The under surface has almost the same mar- 
kings as in oppelii (102 A e), but deeper yellow. 
P. tryphena Hew. (102 Af) from Colombia has a large yellowish-green spot on the forewings, which 
is adjoining to a basal stripe of the same colour, a yellowish-green spot at the costal margin and a small 
bluish apical spot. The hindwings have a bluish-grey marginal band and a yellowish-green median spot. The 
under surface resembles that of oppelii, but is paler yellow, and between the 2 black lines there are also several 
small black dots. 
P. vitringa Hew. (102 Ag) from the Upper Amazon has a similar but still paler under surface than 
tryphena, the black upper surface has a yellowish-green band nearly of the same width and leads from the 
costal margin to the inner angle, as well as 2 blue rays at the base of the forewings anda distal-marginal band 
consisting of 4 greenish-blue small spots. 
P. camelita Hew. from Bolivia shows a greenish-blue median band reaching from the costal margin 
to the inner angle, broad blue basal stripe and rather large blue apical spot of the forewings; the hindwings 
exhibit a very broad bluish-green marginal band decreasing in width from the costal margin to the inner angle, 
and some few blue scales in the centre. The under surface is quite similar to that of humboldtii. 
P. lebasii Guér. (102 A g) from Colombia is striking for the blue rays on the hindwings, which are in 
negrina form. nov. from the Upper Rio Negro only alluded to. In this form the greyish-green band of the hind- 
wings is also broader, the lustrous blue band of the forewings, however, narrower. 
P. lanice Hew. (102 Ag) from Ecuador and Peru is above very similar to a little bonplandti, but the 
green band of the forewings is narrower and dentate on both sides. The under surface is quite different, as 
is Shown in the figure. 
P. moronina Sigr. 7. 7. from Peru (Chanchamayo) is somewhat larger than lanice, above hardly differing 
from it, the under surface of the hindwings, however, is darkened to such an extent that, except the light colou- 
ring placed’ distally to the outer dentate line, only an elongated triangular spot distal to the inner black line at the 
costal margin and some very little spots in the centre remain light; the inner, proximally red-edged line is much 
less curved than in lanice and black discal dots are absent. The under surface of the forces has more red 
colouring on the basal part and a complete middle row of blue spots. 
P. guerini Fldr. (102 Ag) from Colombia has almost white under surface of the hindwings; the red 
stripe at the costal margin of the hindwings may also be absent or only indicated; at the basal part of the under 
surface of the forewings there may be a red spot instead of a blue one. 
P. vaninka Hew. (102 A g, h) from Colombia and Peru differs from the similar species by a red stripe 
at the costal margin of the upper surface of the hindwings and by pure blue bands. The Q is hardly different.
