492 CALLITHEA. By J. Roser. 
C. srnkai Honr. (99) from the Upper Amazon is very similar to degandw, but has a broader green 
margin and a wonderful sapphire-blue gloss of the upper surface. On the under surface of the forewings the 
black markings are greatly reduced. _ 
C. salvini Stgr. from Iquitos is also similar to degandw (99f), but the upper surface is of nearly the 
same beautiful blue gloss as in srnkai (99 e) and has just the same metal-green distal margins as the latter, 
but the apex of the forewings itself is also of this colour. Beneath the basal part of all the wings is orange-red, 
the under surface is otherwise similarly marked as in degandti, the inner margin of the forewings, however, 
is broad and deep black. 
C. whitelyi Salv. (99 e) from Peru is above very similar to depwiseti (99d), but it lacks the shaggy 
hair in the discocellular of the hindwings, the whole hindwing except the ae green margin, therefore, 
showing blue gloss. On the under surface of the forewings are 5 submarginal ‘lea spots decreasing in size 
from behind to the front; the red colouring at the base of the wings is lighter than in depuisetz, also some- 
what broadened, especially on the forewings, and the inner black line is divided into large black spots. 
C. lugens Dre. from Peru (Cuzco) is described thus: ¢ head, antennae, neck, shoulder-covers, thorax 
and abdomen black. Forewing very similar to that of C. optima (99 d), but much more lustrous blue, the black 
apical margin much broader; hindwing much more lustrous blue, than in optima, the blue colouring procee- 
ding exactly from the base as in whitelyi (99 e); the greenish distal margin is much broader, too. Under sur- 
face resembles that of C. optima (99d), but without the black lines and with very much less red at the base 
of the hindwings, but with much more red than in lepriewri (99d); a large round red spot at the cell-end; 
the forewings have a submarginal row of 5 rather large black spots. — Although the author compares this 
species with 2 species belonging to 2 different groups of species, yet the remark that the blue of the hind- 
wings begins at the base of the wings as in whitelyi, shows evidently that lugens belongs into the group A 
and the nearer affinity of whitelyt. 
B. gd on the upper surface of the hindwings in the discocellular with 
shaggy hair. 
With C. leprieuri Feisth. (99 d) from Surinam and the Lower Amazon, commences that series of species 
in which the g shows long black shaggy hair of the discocellular on the upper surface of the hindwings; 
for these species C. FELDER has established the genus Cyane which is distinguished especially by shorter 
antennae and longer, stronger palps. C. lepriewri shows a dull blue gloss on the upper surface, being intensified 
on the basal part of the forewings, in the 9, however, only indicated. 
C. depuiseti Fldr. (99 d) from Peru resembles lepriewri, but has a more intense blue gloss of the upper 
surface, which extends also to the hindwings. The greyish-green marginal band of the upper surface is much 
broader and lighter than in lepriewri, the under surface is quite similar as in the latter, the forewings, however, 
showing less black markings. — Rather different is the Bolivian form which we call eudia form. nov. It has 
much broader, also lighter greyish-green margins and a more intense blue gloss of the upper surface. On 
the under surface of the hindwings the golden gloss is confined to the median band in which the black 
spots are placed, these spots are somewhat larger, the distal (submarginal) black line being broader and also 
the red basal spots somewhat more extensive. 
C. philotima Rd. ,,3. Nearly allied to C. depuiseti Fldr., optima Btlr. and whitely: Salb. Differing 
from the former two by a much broader, pale metallic-blue margin of all the wings. The black marginal line 
is much finer than in depuwiseti, also the apical part of the forewings is less extensively black. The fringes 
are snow-white along the margin of all the wings. The jet-black long scent-hair in the disc of the g-hind- 
wings as in depuiseti. — The under surface forms by the disposition of the red basal spots an intermedium 
between depuiseti and optima. The forewings exhibit a short blood-red basal streak of the costal margin and 
only 1 black subapical dot in cellule 5. At the base of the hindwings there are 3 blood-red long spots, one towards 
the costal margin and one towards the inner margin, and one long tooth-like spot in the upper half of the 
discocellular, the sharp point of which is situated about in half the lenght of the discocellular. Also at the 
black transverse vein of the discocellular there are a few red scales. The black macular markings quite 
similar to that of depucset?, which entirely lacks the long red spot in the discocellular, whereas optima shows 
the whole basal area of the hindwings (except a bluish-black spot in cellule 8) of a miniate colour. C. 
whitelyt has only at the base of the discocellular of the hindwings red spots’ the first transverse line of it is 
broken up into short longitudinal spots. 1 ¢ from the Chanchamayo.* 
C. optima Bélr. (99d) from Peru and Ecuador is somewhat smaller and has more pointed domarings 
than depwisett, but much more intensive blue gloss and narrower greyish-green margins of the upper surface. 
Nearly the basal half of the under surface of the hindwings is miniate, the rest of the markings, however, 
very similar to those of lepriewrt. — eminens form. nov. (99 e) from Southern Peru (Upper Madre de Dios, 
500—1200 m) is remarkably different from optima, but nevertheless probably a local form of this species. It 
has been discovered by Mr. A. H. Fasst. The greyish-green margin is on all the wings considerably broader, 
about three times as broad as in optima, therefore the area of the blue gloss is considerably diminished, 
the black spot in the centre of the forewings, which in optima is very conspicuous in most any direction
