wings, proceeding from the base in the cell, mostly terminates at the upper margin of the wings. It is not divided 



as on the forewings. Near to the margin is a row of purple spots running i)arallel to the angle. A second and 



third marginal row goes through the wing. Between the last row and the broad spot, a band'runs into the centre 



through the \\ing. Inclusive of this row and exclusive of the white marginal line. 4 rows of puiple-colou- 



red spots stand between angle and s])ot. The under surface of the wings as in streckeri Skinner, similar to the .•<lrcckn-i.

M. sophronia Godt. (98 f), a very rare species from Brazil, has blue colouring on the hindwings and on supiinni'm 

 the basal part of the forewings, on the latter wings also wliite spots. The $ has a duller, more steel-blue colou- 

 ring, and larger white spots on the forewings. The reflection of this species is very strange. It is in the (^, when 

 the animal is held towards the origin of light, violet-blue, while it is cyan-blue when seen standing between 

 the origin of the light and the butterfly; in the ^ it is green. The species is known to A. Seitz only from 

 Southern Brazil where it flies rather high u}) in the Orgel Mountains and seems to be very rare. He did not 

 come across them near Rio itself, but according to v, Bonninghau.sen it occurs in single specimens to the north 

 of it. According to Staudixger, the species also occurs in the mountains of Venezuela. 



M. antholia Godt. (98 f ) from the Antilles is larger than the preceding species and has black wings of a anihoiid. 

 blue iridescence except the distal margin, the forewings have a large white spot beyond the middle cell and 

 oblicpiely below it another something smaller one. so that they form an interrupted white band. In the apex 

 of the forewings there is placed another smaller white double-spot. The hindwings are without any markings, 

 except the $ in which also the blue reflection is missing nearly altogether, and in which the distal margin is 

 whitish at the front part, and at ';; of the width of the wings there is an effaced line of white dots termina- 

 ting into the costal margin. 



M. capenas Hew. (98 f) from the Upper Amazon shows but little sexual dimorphism; the $ has a r(//;('(i((.s-. 

 more grey ground colouring and more pronounced markings. We have a J at hand from Rio Madeira (Hu- 

 ma^la, June to September), which is considerably smaller and has no brown band on the hindwings, and above 

 the blue inner marginal spot of the forewings there is one more such spot, the under surface being also darker. 

 We denominate this (local?) form as madeira form, hoik — octomaculata Btlr. from Peru differs especially b\^ madc'tni. 

 having 4 instead of 3 bluish spots on its forewings.

39. Genus: I'ybdeli^i Bsd. 



Very much approaching the Eunica, but differing from them by the fur-like haired eyes. The cells of the 

 hindwings, being open in M yscelin, are closed in CyhdeUs. The colouring is throughout above black with white 

 spots and blue reflection which is, however, concentrated upon the surroundings of the spots. The head is 

 rather stout, the eyes very pilose, the jjalps long, at the top lowered, antennae of medium length with flat 

 clavola, the thorax robust, the legs stroitg and the abdomen slender; the forewings angled below the apex, 

 the 1. subcostal vein originating at the cell-end, the 2. right after, the 3. beyond the middle of the wings, the 

 cells of both wings closed, the 2. median vein of the forewings very much bent. Precostal of the hindwings 

 simple, very much bent. There are about 4 forms known that are closely connected with each other; all of them 

 occur in the warmer parts of South America and are rather numerous in some jtlaces. 



We reproduce here a ,^ of C. phaesyle, of which Hubxer figures only the $. The species is probal)ly 

 .scarcely more than the southern form of mnasylus. Typical mnasylus DhJ. and Hew. (102 B h) from ^>nezuela iiniasijUi^. 

 have on the forewing an oblique sjiot behind the cell, 2 little punctiform spots and a larger round dot near 

 the anal angle white, and on the hindwing a white opalescence encircled by a fine violet-blue. — In thrasylla liintsylUi. 

 Fldr. (102 B h) which seems to be an alpine form widely sprend in the north of South America, the margin of 

 the blue opalescence on the hindwing is violet and so much broadened that but a little Avhite luicleus remains 

 in the centre, not larger than one of the white spots on the forewings. — boliviana Salv. (102 Bh) has the h:,r>rian(i- 

 white spot entirely covered by blue, and in phaesyle Hbn. (102 B h) itself the opale.scence on the hindwing is phuesj/ir. 

 missing altogether, the hindwing being unicolorously sepia-brown with quite a faintly dark submarginal line; 

 but behind the cell of the forewings there is a white band consistitig of three bands, which is coiniected with 

 the isolated spot before the anal angle by a violet iridescent band. The latter is the most southern form rea- 

 ching in the east as far as to the mountains behind Rio de Janeiro, in the west as fas as P<>ru and Bolivia. 



40. Genus: liib.ytliiiia Fldr. 



This genus owes its name princij)ally to the palps being, like in a Libythea, prolonged like a nose. 

 J am not able to give any description of their habits and early stages. With the preceding genus behind which 

 it was placed there is, in my opinion, no relationship whatever, but rather with the genus Ergolis. The eyes 

 are naked here, in CybdcUs furry; the antennae gradually and slightly thickened, in Cybdelis with a flat
