PERICOPIS. By Dr. M. Hering. 
1. Abdomen above uni-coloured, without a darker median line, without hardly any sexual dimorphism, forewing 
without diffuse hyaline stripes, with welldefined bands and spots (= Chetone Bsd.). 
catilina. P. catilina Cr. (= nasica F., perspicua Wkr.) (62 a). Wings blackish-brown, markings greenish- 
yellow with white marginal dots. Body above blackish-brown, beneath sand-coloured. Brazil, Colombia, Guiana. 
conjuncta. P. cotljuncta sp. n. (62 a) is quite similar to catilina, forewing at the base behind the cell with a large 
greenish-yellow spot, the posterior edge of the cell and 2nd cubitus very broadly black, whereby the discal 
band is divided into 3 large spots. On the hindwing the transverse vein is not broadly marked black, and therefore 
the light spot clistally to the cell coheres with the yellow ground-colour. Colombia. $ type from the Bio Dagua 
in the Berlin Museum. 
ithomia. P. ithomia Fldr. (62 a) is rather variable, head and thorax black, dotted white or yellow, abdomen 
blackish-brown, at the base more or less ochreous-brown, beneath straw-coloured. Forewing blackish-brown, 
in the basal area without or with ochreous-brown longitudinal stripes at the costa and on the fold. Discal band 
composed of ochreous, yellow or white spots, a likewise yellow or white subapical band, a series of large similar 
marginal spots. Hindwing ochreous, costa basally and distal margin broadly black, with yellow or white marginal 
spots. Panama, Honduras. It copies Heliconius zuleika Hew. (Vol. V, t. 74 c) flying in the same region. 
kenara. P. kenara Btlr. (= $ salvini Fldr., Drc.) (62 a). Forewing similar as in ithomia, the apical spots smaller. 
Hindwing likewise similar to the preceding, but the veins and costa quite black. Forewing beneath at the base 
separata, broadly ochreous-yellow, with a black cellular spot. — The form separata form. nov. (62 b) has the band of 
the hindwing broken up into broad black streaks on the veins. Panama, Colombia, Venezuela. 
angulosa. P. angulosa Wkr. (62 b). Scheme of markings in the forewing as in ithomia, but the base of the forewing 
is broadly ochreous-brown, with a black wedge in the cell. Discal band at least behind the cell ochreous-brown. 
heliconides. Hindwing as in ithomia. Veins finely black. Colombia, Venezuela. — heliconides Bsd. (= irenides Btlr.) (62 b) 
from Central America (Honduras, Panama) has the wedge at the base of the forewing connected with the 
bordering of the ochreous-brown area. 
suprema. P. suprema sp. n. (62 b). Body and forewing as in typical angulosa, the yellow discal band of the 
forewing is much broader, light brimstone-coloured, steeper; it terminates considerably far before the proximal 
angle. Margin of the hindwing much broader black, its proximal edge going across the transverse vein. Costa 
not black. Colombia, Ecuador. type from Rio S. Juan in the Berlin Museum, $ paratype from Zamora in 
the Tring Museum. 
phaeba. P. phaeba Bsd. (= ithrana Btlr.) (62 c). Head and thorax black, dotted white and ochreous, abdomen 
above brown, beneath straw-coloured. Forewing blackish-brown, at the base one or several longitudinal lines 
varying from red to ochreous-brown, with a yellow broad discal band ending obtuse at the 2nd cubitus or pointed 
behind it, 1 to 4 yellow subapical spots and a series of white marginal spots. Hindwing with a broad black 
costal margin and distal margin, in the latter a series of marginal spots varying from ochreous-yellow to red- 
brown, the veins thickly black, otherwise ochreous-yellow to red-brown. Guatemala to Colombia, Ecuador, 
intersecta. Peru, Upper Amazon River. — In the form intersecta form. nov. (62 c) the marginal band of the hindwing is 
broken up into thick black streaks which are situate to the right and left of the ends of the veins; the basal 
parts of the veins are less thickly black. As this form only occurs in the Amazon District and Eastern Peru, 
it is perhaps the southern race of the species, but perhaps also a distinct species. It copies Heliconius aoede 
Hhn. (Vol. V, t. 76 f). 
meta. P. meta Drc. is unknown to me in nature. Quite similar to intersecta (62 c), but the head and 
thorax are black, the hindwing in the ground-colour pale yellow. Colombia. 
phyleis. P. phyleis Drc. (62 c) varies a great deal in the different specimens. Head and thorax similar to 
phaeba, but abdomen beneath chocolate-brown. Forewing blackish-brown, at the base of a variably extensive 
ochreous colour. A broad brimstone-coloured discal band rarely extends somewhat beyond the 2nd cubitus, 
some yellow or white submarginal dots. Hindwing blackish-brown, with reddish-brown or ochreous-brown 
internerval stripes which are often very much reduced. Colombia, Ecuador, Peru, and Bolivia. It copies 
Heliconius melete Fldr. (Vol. V, 77 b). 
mimica. P. mimica Fldr. (62 c) is similar to phyleis, the brown dusting on both wings is much scantier, 
the hindwing being sometimes uni-coloured black, a subapical row of spots is parallel to the discal band, marginal 
spots are wanting. Colombia. 
isse. P. isse Him. (62 d). Body coloured as in most of the species of this subgenus, forewing,blackish-brown, 
rarely at the base with two ochreous-brown longitudinal lines; discal line narrow, uniform, extending to the 
axillaris, a subapical band composed of 3 yellow spots, and white marginal spots. Hindwing ochreous-yellow, 
with black veins and a narrow black margin, before this a broad black band which is distally extended on the 
veins and connected there with the margin; costa likewise black, analis and stripes before and behind it likewise 
black. Brazil. 
decisa. P. decisa Wkr. (62 d) is similar to isse, the discal band is narrower, behind more pointed, subapical 
spots hyaline, shaded somewhat with yellorv. Discal cell of the hindwing and partly its surroundings brimstone- 
coloured. South Brazil. 
studyi. P. studyi sp. n. (62 d) is likewise similar to isse, 3 wood-coloured longitudinal lines at the base of 
the forewing, all the markings hyaline, the discal band broader, behind tapering, terminating a little before
