556 PREPONA. By H. FRUHSTORFER. 
resembles P. antimache, but the blue subapical spots of the forewings are almost vertically placed below each 
other and the median band is likewise set more steeply. — The valve is somewhat more slender than in antimache 
tyrias Fruhst. from Rio Grande do Sul. From Cuba where it is rare. 
P. camilla, an extremely localized species of which only few specimens have become known. Its 
relationship to P. antimache is about like that of P. phaedra to P. demophon. camilla may be considered as the 
species being the most conspicuously decorated in blue we know, and in no other species we find such a luxuriant, 
magnificent area of a greenish lustre, as in camilla. The blue zone as well as the preapical blue vary accord- 
ing to the locality of the two territorial forms. — camilla Godm. and Salv., described from Nicaragua and 
Panama, bears two elongate, narrow blue preapical stripes and a magnificent band excelling but slightly the 
extension of that of P. demophon. Under surface preponderantly light ochre-yellow with a brown longitudinal 
band of the forewings, being divided at the posterior radial. — metabus subsp. nov. *) shows three light-blue, 
broad streaks and a more extensive magnificent band of the forewings than camilla. The under surface is con- 
spicuously differentiated by brownish-yellow colouring with extensive yellowish areas of a silvery gloss. Colom- 
bia, originating from a so-called ,, Bogota-consignment“‘, but surely taken near Muzo, from where it lay likewise 
before me, out of on altitude of 7 to 800 m from more modern collections. 
P. meander. One of the most noted species and beneath easily discernible by the sharply delimited 
dark-brown distal half contrasting strongly with the lighter, whitish or grey basal zone of a silvery gloss. There 
is a conspicuous whitish, roundish or crescentic spot at the subcostal of the hindwings. The upper surface 
differs but slightly from that of P. demophon, but light greenish or bronze-glossy bands, as in P. demophon 
and P. antimache, do not occur. The 9 beats the $¢ in size and exhibits more imposing transcellular stripes 
of the upper surface ‘of the forewings, and beneath, the outer wing-half presents itself somewhat more 
faded brown. According to the locality, the size of the specimens varies, reaching the maximum of deve- 
lopment in the Andine region, the minimum in the South Brazilian races. The geographical range coincides 
with that of P. demophon. In the north, Mexico is yet inhabited by the species, in the south, Rio Grande do 
Sul. — phoebus Bsd., the northernmost branch, described from Guatemala, is lying before me from the Vol- 
cano Chiriqui and the Cauca Valley from Colombia. The preapical blue spots of the forewings somewhat more 
extensive and of a brighter lustre, and the under surface of the forewings in their outermost part some- 
what more fallow than in the Surinam-form. — meander Cr. (111 c¢) of which we figure a 9 from Surinam, the 
habitat of the nomenclatural type, occurs in the same form also on the Lower Amazon. A similar race is found 
on the Isle of Trinidad. — megabates subsp. nov. is in the male sex as large as the figured Surinam-9, the 
blue spots distal from the forewing-cell appear somewhat smaller, and the basal zone of the under surface of 
the hindwings is somewhat darkened. Peru, Bolivia. — megacles form. nov. inhabits Central Brazil. Both the 
sexes are beaten in the habitus by the vicarious types mentioned so far, being coincided by a reduction of 
the blue magnificent bands. The basal zone of the under surface of the forewings mostly appears covered 
by dark-grey or violet, the antiterminal margin of the forewings more sharply defined than in meander coin- 
ciding thereby with phoebus and megabates. Type from Espiritu Santo, at hand also from Minas-Geraes. Near 
Rio de Janeiro not very common. — soron subsp. nov. (111 ¢) is based upon specimens from Theresopolis 
in Santa Catharina. The shape of the wings grows more pointed and narrower than in megacles, the blue spots 
-and bands of the upper surface are still more reduced than in the Central Brazilian areal form. On the under 
surface of the forewings, the antiterminal margin is confluent with the dark ground-colour as in meander. Hind- 
wing generally lighter brown with fading distal zone. — amphimachus is here deprived of its rights as species, 
which Barres, Kirsy and STAUDINGER have assigned to it, whereas I took it to be a side-form of P. meander, 
following the example of GopMaNn and Satyry. The form antimachus is generally more common, especially 
in the Andine region, not at all rare in Mexico, very common in Central America, whereas the proper meander 
are of a rare occurrence there. The wing-contour is deviating, more roundish, the blue band is more extensive 
in the northern races, the under surface nearly always ochre-yellow, the median band always pregnant, the 
distal zone sometimes darkened, but even in the most melanotic races never extensively brown and sharply 
defined as in meander. Basal region of the hindwings especially in the 2 always faded yellow instead of whitish. 
amphimachus has always the subcostal white spot of the hindwings in common with meander. amphimachus 
occurs at the same time with P. meander. Vertically it rises up to 2000 m, whereas meander seems to be homed 
more in the lower regions. — cinetus Fruhst. was already in 1904, considered by myself to be a form of 
the dry period of P. meander. It is indeed the northernmost branch. Habitus smaller than the Central American 
sister-race, the subapical blue spots being also reduced. Under surface preponderantly greyish violet, as well 
as the distal half of the hindwings. Mexico. — amphiktion subsp. nov., an excellent geographical form, beating 
in size the Amazon- and Surinam races. The magnificent band of the upper surface of a lighter and more glossy 
blue, the transcellular spots very large. Under surface of the $3 extensively clouded with brown, whereby 
a deceptive likeness with meander is produced; 2, however, immediately distinguishable from amphimachus
