496 PERISAMA. By J. Résnr. 
C. asta Salv. (102 Aab) from Mexico which we have become acquainted with only from the figure, 
greatly differs from the affined species on the upper surface by the absence of a red band. 
C. hydarnis Godt. from Southern Brazil, being very rare, resembles hesperis, but it has a straighter 
distal margin of the forewings, the deeper band of the forewings is narrower, does not reach to the costal margin 
and ends far from the inner angle; the basal part of the forewings has the same beautiful blue reflection 
as the hindwings; before the apex of the wings stands a small white spot. Under surface not unlike that of 
pygas, but blue spots missing, the anterior ,,eight“‘ is formed very regularly, the posterior ,,eight‘‘ some- 
what less, and the submarginal chain-band of the hindwings is centrally indistinct. 
C. hesperis Guer. (102 A b) from Colombia, Peru and Bolivia presents itself as a charming little animal 
in its broad, dark red band of the forewings and the intensive light blue reflection on the greatest part 
fo the hindwings and the basal area of the forewings, which is also noticeable in one or several small dots in 
the apex of the forewings. — parima Hew. from Ecuador has narrower and lighter red band of the fore- 
wings and a more expanded blue reflection of the hindwings. 
C. mellyi Gwen. from Peru (lying before us from the Chanchamayo). The author takes it to be a 
species of its own and compares it with hydaspes and hesperis. We think that it differs from hesperis only 
by the submarginal bands being more yellow on the under surface. 
C. patelina Hew. (102 Ac) from Guatemala has the same magnificent upper surface, but different 
under surface being of black ground-colouring; it is represented by the last figure of the row 102 Ac which 
by a mistake is signed ,,aretas U“. 
C. pitheas Latr. (102 A b) from Panama and Venezuela has light red bands of the upper surface and 
peculiar pale-red, sometimes yellowish ground-colouring of the under surface of the hindwings. The scarcely 
differs from the g. 
C. cyclops Stgr. from the Tapajoz (Amazon) has a very long red band of the hindwings reaching 
almost to the distal margin. — columbiana Stgr. from Colombia differs by a short oval red band of the hind- 
wings and broader black markings of the under surface. — centralis Stgr. from Chiriqui has a longer and 
broader red stripe of the hindwings; the anal eye-spot mostly has 2 white spots. 
C. aretas Hew. (102 Ac, 4. and 5. figure) from Venezuela has light-red basal half of the forewings 
and on the hindwings a larger red central area than pitheas; in the apex of the forewings is a short reddish- 
yellow band. The under surface has the same markings as pitheas, the ground-colouring, however, is more 
yellow. On table 102 A the upper surface has by mistake been denoted by maimuna, the under surface by 
patelina U; the last figure of the row denoted by aretas U represents patelina. 
C. sorana Godt. (102 Ac) from Brazil, Paraguay and Bolivia differs considerably from all the species 
by the markings of the under surface of the hindwings. The 9 has the red band of the hindwings only 
indicated and a strong blue reflection of the hindwings and a shorter almost white apical band of the forewings; 
the red bands of the forewings also have a bluish shine. — latona Btlr. from? (presumably Venezuela) has 
a larger red basal area of the forewings and much smaller red area of the hindwings, but in the middle of 
the hindwings a blue gloss. 
C. oculata Gwen. has a large crimson basal spot of the forewings, which is divided by the black 
veins; forewing without reflection, but hindwing with light greenish reflection. Under surface the most similar 
to sorana, but considerably different; the red median band of the forewings is absent, the subapical band 
rather broad and blue; ground-colouring of the hindwings black, far away from the distal margin a sharply 
dentated blue band (thick line), the two eyespot-markings distally not closed, each with only one blue spot. 
Habitat unknown. 
44. Genus: Perisama Dbl. 
The species belonging to this genus are of almost the same size (medium size). They are confined to 
the mountains of tropical America and easily to be recognized by their exterior: velvety-black upper sur- 
face with glossy blue or green bands on the upper surface of the forewings and mostly the same or greyish- 
green band at the distal margin of the hindwings; the under surface is very characteristic: on a whitish, grey 
or yellow ground 2 black, either almost straight or curved or dentate lines between which there are often 
black dots. The first stages are not yet known. We unite the species formerly included in Myscelia and separated 
by E. Scrarz as Orophila, with Perisama, because they do not show any symptoms that would justify their 
separation, 
P. bonplandii Guér. (102 A d) from Colombia is the largest species of this genus. The 9 is hardly different 
from the 3. — Specimens with very light and nearly unmarked under surface of the hindwings have been 
described as albipennis Bélr. (102 Ad). — d@orbignyi Guér. are specimens in which on the under surface of
