ADELPHA. By H. FRuHSTORFER. 519 
the white median area of the hindwings 8 mm broad (4 mm in erotia). Under surface very faded, the other- 
wise yellowish maculae of the forewings almost of a purely white colour. All the longitudinal bands light- 
yellow instead of reddish-brown as in the Andine allies. Base of the hindwings with purely white extensive 
stripes. Venezuela, from the peninsula of Patar, collected in August. Type in the Tring- -Museum. — delinita 
subsp. nov. (106 f). The ochreous longitudinal band of the forewings more compact, i. e. more uniformly broad 
and distally less dentate than in deleta and erotia. Median band of the hindwings, especially considering the 
size, relatively narrow, distally bordered with ochre-yellow frequently in the anterior part, sometimes also in 
its full length. Wings of the $4 beneath dark reddish-brown with reduced white submarginal bands. Type 
from Colombia (Cauca Valley m foute a similar form is found in Central America from Guatemala to Panama. 
Specimens from the latter habitat have, according to Gopman, remarkably much white in the submedian zone 
of the forewings. — permagna subsp. (or form.) nov. (106 e) was found on the Rio Dagua in Colombia. The 
white hue of the forewings also here sometimes attains a certain extent, but it may almost disappear in jg 
from the same habitat. permagna beats all the well known erotia-races by its considerable size and the 
more extensive Submarginal white spotting of both the wings. permagna seems to be distributed from Colombia 
throughout the whole district of the Upper Amazon as far as French Guiana, for there is a magnificent 92 
lying before me from the latter district, as well as gg from Marcapata (Peru). — erotia Hew. (106 e) 
was described by its author according to a relatively small 9 from Bolivia and occurs pretty conformably in 
many parts of Peru and Ecuador. Ground colour of the under surface more reddish-brown instead of loam- 
yellow as in the Colombian races. The median band of the hindwings variable, sometimes bulged out, and 
the narrowest in a g from Ecuador. — $¢g with white embedment in the submedian part of the forewings, 
albina form. nov., are especially common in the Amazonas-part of Peru where they occur beside gigantic per- 
magna. In Ecuador and Peru erotia was yet collected in altitudes of 4000 and 4500 feet, it inhabits, however, 
preponderantly the hot valleys. — fugela form. nov. is a peculiar, relatively small form reminding us on the 
upper surface of A. davisi (106 ¢) and metana (106d) by small subapical spots and an especially pale median 
zone of the forewings, beneath, however, showing all the marks of erotia by purely white stripes on light 
reddish-brown ground. They are possibly considerably differentiated, deviating specimens of a dry period, since 
beside the type from Obidos another $ from Bahia is lying before me. — uta form. nov. forms an intermediary 
between A. boeotia and A. sichaeus. 3: upper surface very similar to A. sichaeus, but with much lighter longi- 
tudinal bands of the forewings, with a light-yellow hue especially in the anal direction and being especially 
distally more strongly indented. The subapical maculae are more isolated. The white median band of the 
hindwings, by its shape, reminds us more of A. valentina Fruhst., being very much strangulated below the 
broadened costal spot, tapering also in the anal direction where it exhibits a bluish-violet hue. Under surface: 
all the spots of the median band of the forewings are placed in one vertical row and are not moved proxi- 
mally at the cell-apex. The violet submarginal spots combined to completer bands, the other violet spots 
light, the basal bands white instead of grey. White median area of the hindwings more irregular, the reddish- 
brown submarginal band is absent and replaced by a series of indistinct white effaced spots. Ground colour 
much lighter reddish-brown. Forewing more roundish, hindwing narrower, more undulate. Bolivia, 1 g collected 
by A. Banc-Haas, and 2 3¢ from Honduras in the Coll. FRuHSTORFER. 
A. delphicola has been described in the famous book of travels: ,,Two Years among the Indians‘ 
by Dr. TH. Kocu-Grinperc, Berlin 1910, p. 308, the clasping-organs being figured p. 359 beside those of A. 
erotia. delphicola is above hardly to be separated from A. erotia, the under surface, however, is in many parts 
so very different that it may be considered as a parallel species of erotia, just like A. aethalia Fidr. and 
A. euboea Fidr. being above almost analogous, are also occurring simultaneously. The under surface of A. 
delphicola may easily be mixed up with that of A. euboea, while the total colouring of A. erotia and A. aethalia 
is very much alike. In substance, delphicola deviates beneath from A. erotia by the darker, preponderantly 
coffee- or violet-brown total colouring and by compact whitish bands in the submarginal part of the hindwings 
instead of the isolated white spots of erotia. The subbasal stripes, especially of the hindwings, are not purely 
white, but beautiful greyish-violet. Tegumen with a broader appendage of the uncus. Valve with extremely 
slender, unarmed exterior part, while that of A. erotia bears 4 sharp points. Clunicula narrow, high, that of 
erotia obtuse and low. — nava subsp. nov. (106 f) was discovered in Eastern Bolivia in the Province of Sara. 
The greyish-violet faded under surface makes entirely the impression as if the specimens collected from the 
end of February to the beginning of April belonged to a dry period. — praetura subsp. nov. (106f) was 
figured according to a j from the Rio Demerara (Butish Guiana). The yellowish-brown part of the forewings 
more extensive and ker than in nava, the white median band and the subanal spots of the hindwings more 
reduced. The longitudinal stripes of the hindwings remarkably broad, partly purely white. Widely distributed, 
in my collection from Surinam (Cayenne), Mato Grosso and from the Lower Amazon. — delphicola Fruhst. 
based upon considerably smaller specimens being beneath very much darkened, from the Upper Rio-Uaupes, 
the Upper Amazon and Peru. — ophellas subsp. nov. denotes a magnificent form with especially luxuriant 
yellowish-brown preapical spots, acutely angled median band of the forewings, which is widely overflown in 
white in the anal direction. The under surface similar to that of nava, but more variegated, with sharper deli- 
mited, whitish-violet stripes. Espiritu Santo and further inland as far as Paraguay.
