CALLITHEA. By J. Rr.BER. 4!tl 



cairiously buttoned antennae, tlie palps are densely covered with scales and hair, their last joint is small and 

 pointed, the eyes are naked, the hindwings have a double-furciforni precostal. 



The larva of Cnll. sirpphira was observed by Otto jMichael near Santarem on the Lower Amazon, 

 but unfortunatel_y he did not give any further details; he merely states that the male larvae are of a lieautiful 

 blue colouring, while the female larvae are more greenish or orange coloured; they have sharp sjjjnes 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. 



Paul Hahnel reports about the intellectual powers of the Callitheac 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 uji in order to 

 hide itself on the under surface of a leaf hanging down above it — it probably imagined to be cj[uite safe there; 

 the observer was really astonished at this clear thinking power of the animal so hardly pressed upon by its 

 persistent pui-suer. 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 $ 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 c) from Colombia and from the LTp])er Amazon differs from the following hncU>ioiii. 

 markii (99 f) by a larger yellowish-red basal area of the upper surface of the fore'\\ings; 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 ochrc-ycllow. 



C. markii Hew. (= wallacei Stgr.) (99 f) from the Upjier Amazon has, -with the exception of the nuirki'i. 

 inner margin, totally blue, glossy hindwings and a broad blue-shining distal band of the forewings. The 2 has 

 a rather broad verdigris band on the ujjper surface of the forewings.

 gloss and is of orange-red colour on the basal part of the hindwings. On the under surface, which is nuich more 

 marked in black, the basal third of the hindwings is orange-yellow, too. 



C. buckleyi Hew. (99 e) from Ecuador differs from staudingeri suh.s-p. nov. (= buckleyi Slgr.) from hucklctii.

 gins of the upjjer 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. (99 f not degandei) from the Upper Amazon has a bluish-black upper sur-face with ilcgdmlii. 

 very broad verdigris margins. According to Hewitsons figure the whole middle part of the u])per surface of 

 the wings is of a deep blue gloss, which is seen in the $ only exceptionally. 



C. bartletti Godm. and <SV//;'. from the Lower LTcayali and Rio Napo is described as follows: ,^ above dee]) hurtlilli. 

 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; re.st of all the wings gi-een; 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), jilaced parallel to the distal mai-gin. The 

 apex of the hindwings is more rounded in the $ than in the (;J; base of the wings greenish-black instead of 

 jnn-ple (blue); the green margin of all the wings broader. — We cannot jjcrceive from this descrijition whether 

 bartletti is a form of degandii or adamsi. Presmnably the latter is also a form of degandii. 



C. adamsi Lathy (99 e) from Peru (Perene, 4000 feet) is above much darker than degandii and has adatn.si. 

 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 .sub.s-p. nov. from Peru (Cuzco) is above hardly differing jrUjga. 

 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 nnich more developecL
