PERICOPIS. By Dr. M. Hering. 437 
hindwing composed of 2 or 3 red spots, only extending to the 2nd median. Venezuela. <$ type from Maracaibo 
in the Berlin Museum. 
W. joiceyi Dgn. Forewing black, marking as in the prece ding, hindwing with larger spots (red or joiceyi. 
white?), extending to the 1st cubitus. Colombia. 
E. drucei Schs. (61 f). Ground-colour of the wings'as in rubrimaculata, the red costal spot of the forewing drucei. 
distantly remote from the band which is broader than in the two preceding species (maximum 5 mm). Hindwing 
with a red costal spot and some adjoining whit6 spots. Venezuela to Costa Rica. 
E. dejanira Drc. (61 g). Ground-colour of both wings bluish-black, the white bands in the forewing dejanira 
and hindwing very broad, the red costal spot remote from the band, a similar one on the hindwing beneath. 
Colombia. 
b) Discal band of the forewing yellow. 
E. arcaei Drc. (61 g) entirely resembles E. albimacula Drc. (61 f) with the exception of the yellow arcaei. 
band. Honduras, Panama. 
c) Discal band of the forewing red. 
E. temperata Wkr. (== jucuncla Fldr., egaensis Btlr.) (61 g). Black, with a blue lustre, the last temperata. 
5 ventral segments red, edged with white. Base of all the wings with a blue lustre, fringes at the apex white, 
partly also on the hinclwing. Discal band of the forewing pale red, at least at its broadest place. 3^4 mm broad; 
the oblique band of the hindwing likewise red and rather broad. From Guiana and Colombia to South Brazil. 
E. hystaspes Btlr. (61 g) is similar to the preceding, the discal band of the forewing is dark red, liystaspes. 
narrower, never extending into vein 3. Band of the hindwing narrow, broken up into spots, sometimes being 
absent, but in this case there is beneath at least one red spot. Venezuela. 
E. chalybea sp. n. resembles hystaspes (61 g), the discal band of the forewing extends to the tornus, clxalybeu. 
whereas in the two preceding it terminates at the axillaris, about as broad as in temperata. The band of the 
hindwing is long, more remote towards the margin than in the allied species and more parallel to the margin, 
extending into cell 2; not broken up into spots. Cinder surface like the upper. $ type from the Rio Songo 
(Bolivia) in the Berlin Museum. 
E. calida Fldr. (61 g). Forewing without an intense blue lustre at the base, only strewn with greenish- calida. 
blue scales. Discal band of the forewing extending to the posterior margin, dark red; band of the hindwing 
as in temperata, sometimes wanting above. Colombia. 
E. meres Drc. Body in this species and the following quite black, abdomen with a blue lustre. Forewing meres. 
black, with a red line from the costa to the tornus beyond the cell. Hindwing black, with a blue lustre. Colon bia. 
(This species was not before me.) — Expanse of wings: 45 mm. — E. constrictifascia Dgn. -which was mentioned 
in the genus Thyrgis (p. 428), may also belong hereto. 
E. ambigua sp. n. (61 g). Body and wings of the same ground-colour as in meres, but the forewing ambigua. 
is violettish-brown. A flesh-coloured discal band runs rather straight across the last quarter of the discal cell 
to the tornus. Hind wing with a peculiarly dull blue lustre. Honduras, o type in the Berlin Museum. 
E. gundlachia Schs., from Cuba, has remained unknown to me and is doubtfully placed here. gundlachia. 
16. Genus: Perlcopis Hbn. 
In this genus we also comprise the Chetone Bsd., Sermyla Wkr., Dysschema Hbn. (partly), and Thebrone 
Bsd., because these genera are only founded upon coloristic marks and are therefore of subgeneric value at 
most. It is the most polytypical genus of the subordinate family, in the colouring, marking, arid wing-contours 
particularly copying species of Heliconius with which they also fly together. Sometimes the screening hue 
only refers to the $$. In this genus and the following genera the posterior tibiae only exhibit terminal spurs 
denoting a more continuous specialization corresponding with the mimetic habitus. In the forewing the 2nd 
radial branch rises separately, but mostly anastomoses with the forked radial branches 3 to 5. The 5th radial 
rises before the 3rd. The pinnae of the $ antennae are shorter than the diameter of the shaft, whereby the genus 
differs from Phaloe and others. The SB are often different from the mimetically coloured $$; this sexual 
dimorphism is not yet known in all the species, so that later on probably some species will have yet to be 
combined.
