CALLITHEA. By J. Résrr. 491 
curiously buttoned antennae, the palps are densely covered with scales and hair, their last joint is small and 
pointed, the eyes are naked, the hindwings have a double-furciform precostal. 
The larva of Call. sapphira was observed by Orto MicuarL near Santarem on the Lower Amazon, 
yut unfortunately he did not give any further details; he merely states that the male larvae are of a beautiful 
blue colouring; while the female larvae are more greenish or orange coloured; they have sharp spines con- 
taining a caustic or venomous substance and live in single specimens on a bean-like creeper. The time of flight 
lasts but a short time; they mostly stay in the woods, but also fly single into the boroughs where they have 
been found after the night’s rest on the walls of houses. 
PsauL HAHNEL reports about the intellectual powers of the Callitheae that a markii (hewitsoni) after 
having been several times chased up, at last took refuge on a small trunk where it, however, hardly rested 
and in the very same moment changed its mind and immediately went some inches higher up in order to 
hide itself on the under surface of a leaf hanging down above it — it probably imagined to be quite safe there; 
the observer was really astonished at this clear thinking power of the animal so hardly pressed upon by its 
persistent pursuer. The Callitheae (like many butterflies with an intensive blue) have, according to the same 
observer, a scent. very similar to that of vanilla.

a conspicuous sexual difference. The wonderful saphire blue of the ¢ is not equalled by any other Callithea- 
species and the 9 is on account of a broad ochre-yellow band of the forewings a most remarkable appearance. — 
The larva has been described above. 
C. hewitsoni Stgr. (99) from Colombia and from the Upper Amazon differs from the following hewitsoni. 
markii (99f) by a larger yellowish-red basal area of the upper surface of the forewings; the colouring of this ~ ~/ 
part of the wings changes off rather considerably, since all shades from yellowish-red to ochre-yellow are 
found in it. This area has also on the under surface of the forewings the same extension, its colouring, howe- 
ver, does not change off so very much and is generally ochre-yellow. 
C. markii Hew. (= wallacei Stgr.) (99f) from the Upper Amazon has, with the exception of the markii. 
inner margin, totally blue, glossy hindwings and.a broad blue-shining distal band of the forewings. The 9 has 
a rather broad verdigris band on the upper surface of the forewings.

gloss and is of orange-red colour on the basal part of the hindwings. On the under surface, which is much more 
marked in black, the basal third of the hindwings is orange-yellow, too.

gins of the upper surface, and beneath by less black colouring on the forewings and reduced black markings 
also on the hindwings, especially conspicuous on the band bordering on the ochre-yellow basal part. 
C. degandii Hew. (99f not degandei) from the Upper Amazon has a bluish-black upper surface with degandii. 
very broad verdigris margins. According to Hrwirsons figure the whole middle part of the upper surface of 
the wings is of a deep blue gloss, which is seen in the 9 only exceptionally. 
C. bartletti Godm. and Salv. from the Lower Ucayali and Rio Napo is described as follows: ¢ above deep bartletti. 
purple (blue), central area of the forewings mostly black. Apex of forewings (broad) and distal margin of the 
fore- and hindwings metallic green. Beneath: basal third of the forewings and basal half of the hindwings ochre- 
yellow; rest of all the wings green; at the cell-end and at the first median vein of the forewings blackish; 
1 black spot between the 1. and 2. median vein and 3 others run parallel to the distal margin; the hind- 
wings have 4 bands of black spots on the discal half (? distal half), placed parallel to the distal margin. The 
apex of the hindwings is more rounded in the 2 than in the 3; base of the wings greenish-black instead of 
purple (blue); the green margin of all the wings broader. — We cannot perceive from this description whether 
bartletti is a form of degandii or adamsi. Presumably the latter is also a form of degandit. 
C. adamsi Lathy (99e) from Peru (Peréné, 4000 feet) is above much darker than degandii and has adamsi. 
narrower verdigris margins, the blue gloss is dark violet, the centre of the wings without gloss. On the under 
surface the orange-yellow basal part is darker, very much reduced and, on the forewings, confined to a basal 
spot, the black markings are different, too. — frigga subsp. nov. from Peru (Cuzco) is above hardly differing frigga. 
from adamsi, but shows beneath the yellow basal area on the hindwings extended as in degandii, on the fore- 
wings, however, more extended, the black markings are also much more developed.
