the white median area of tlie hindwings 8 mm broad (4 mm in erofia). Under .surface very faded, the other- 

 wise yellowish maculae of tlic forewings almost of a purely white colour. All tiie longitudinal bands light- 

 yellow instead of reddish-brown as in the Andine alHes. Base of the hindwings witli purely white extensive 

 stripes. Venezuela, from the peninsula of Patar, collected in August. Type in the Tring-Museum. — delinita (icVniild. 

 subsp. 710V. (10() f). The ochreous longitudinal band of the forewings more compact, i. e. more uniformly broad 

 and distally less dentate than in deleta and eretia. Median band of the hindwings, esiDeciallj- considering the 

 size, relatively narrow, distally bordered with ochre-yellow frequently in the anterior part, sometimes also in 

 its full length. Wings of the ,^^ beneath dark reddish-brown with reduced white submarginal bands. Type 

 from Colombia (Cauca Valley). Quite a similar form is found in Central America from Guatemala to Panama. 

 Specimens from the latter habitat have, according to Godmak, 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 yrruuujua. 

 white hue of the forewings also here sometimes attains a certain extent, but it may almost disappear in ($^ 

 from the same habitat, permagna beats all the well known ero<ia-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 $ 

 lying before me from the latter district, as well as (j^J' from Marcapata (Peru). — erotia Hew. (106 e) rroiia. 

 was described by its author according to a relatively small $ from Bolivia and occurs pretty conformably in 

 many parts of Peru and Ecuador. Ground colour fif the under surface more reddish-bro\\ n instead of loam- 

 yellow as in the Colombian races. The median band of the hindwings variable, sometimes bulged out, and 

 the narrowest in a (^ from Ecuador. — o(^ with white embedment in the submedian pait of the forewings, 

 albina form, nov., are especially coiumon in the Amazonas-part of Peru where they occur beside gigantic per- albina. 

 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 j^eculiar, relatively small form reminding us on the fii<jr/ii. 

 upper surface of A. davisi (106 c) and metana (106 d) by small subajjical spots and an especially pale median 

 zone of the forewings, beneath, however, showing all the marks of erotia by purely white strijjes on light 

 reddish-brown ground. They are possibly considerably differentiated, deviating specimens of a dry period, since 

 beside the type from Obidos another (J from Bahia is lying before me. — uta form. nov. forms an intermediary »/«. 

 between ^4. boeotia and A. sicJiaeus. (^: upper surface very similar to A. sichaeus, but with much lighter longi- 

 tudinal bands of the forewiiigs, 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 veiy nuich strangulated below the 

 broadened costal spot, tajDering also in the anal direction wdiere it exhibits a bluish-violet hue. Under suiface: 

 all the .spots of the median band of the forewings are jjlaced 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 q collected 

 by A. Bang-Ha.\s, and 2 (^,^ from Honduras in the Coll. Fruhstorfer. 



A. delphicoia has been described in the famous book of travels: ..Two Years among the Indians" 

 by Dr. Th. KoCH-GRiJNBEEG, Berlin 1910, p. 308, the clasping-organs being figured p. 359 beside those of .-l. 

 erotia. delphicoia 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 Fldr. and 

 A. euboea Fldr. being above almost analogous, are also occurring sinudtaneously. The under surface of .4. 

 delphicoia may easily be mixed up with that of ^4. euboea, while the total colouring of A. erotia and A. aethalia 

 is very much alike. In substance, delphicoia deviates beneath from A. erotia by the darker, preponderantly 

 coffee- or violet-brown total colouring and by compact w hitish 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 extreiuely 

 slender, unarmed exterior part, while that of .4. erotia bears 4 sharp points. Clunicula narrow, high, that of 

 erotia obtuse and low. — nava .s'ltb.sp. nov. (loOf) was discovered in Eastern Bolivia in the Province of Sara. nava. 

 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 praclnra. 

 figured according to a ,^ from the Rio Demerara (British Guiana). The yellowish-brown part of the forewings 

 more extensive and darker 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. U'idely distributed, 

 in my collection from Surinam (Cayeinie), Mato Grosso and from the Lower Amazon. — delphicoia Fnih-M. dflphirola. 

 based upon considerably smaller specimens being beneath very much darkened, from the Upper Rio-Uaujies, 

 the Upper Amazon and Peru. — Ophelias subsp. nov. denotes a magnificent form with especially luxuriant, ojili('Ua.<i. 

 yellowish-brown jDreapical 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 miva, but more variegated, with shaiper deli- 

 mited, whitish-violet stripes. Espiritu Santo and further inland as fai- as Paraguay.
