approaches again more the Colombian vicarious type. The white band of the hindwings still more broadened 
than in metana, and on the forewings the beginning of a white hue in the submedian region being especially 
distinct in a 3 of my collection from Mato-Grosso. — pollina subsp. nov. was recently discovered by 
Le Movtr in Cayenne. The very light zone of the forewings deeper indented at the cell-apex and the white 
median band of the hindwings considerably narrower than in aethalia from Colombia. Under surface similar 
to that of frusina, but more intensely reddish-brown. 
A. euboea might above be easily mistaken with A. aethalia, the only thorough difference being 
noticed in the yellowish-brown zone of the forewings greatly narrowed towards-the submedian. The white 
stripe of the hindwings is also tapering and we nearly always notice an inclination to forming a violet or blue 
proximal boundary-line whereby a certain analogy is created to the Indian Pantoporia; a genus replaced by 
the Adelpha in South America. The ground-colour of the under surface is a beautiful brown with bright violet 
stripes as we meet again in A. phliassa (107 a). Anatomically euboea is sharply separated from all the allies 
by the extremely long, very sharp and much higher appendage to the valve. The valve is, besides, laterally 
and ventrally swollen, the uncus formed like the beak of an eagle, slender with distinct point. — fabricia subsp. 
nov. (106 d) is a form distinguishable from the name-type, euboea Fldr., by smaller size and throughout darker 
total colouring. fabricia has, besides, a distally sharper delimited ochreous band not showing in the anal direc- 
tion the white hue peculiar of ewhoea. On the under surface the bands of fabricia are decidedly narrower. Colom- 
bia, without exact habitat. According to Kayes, a similar form occurs in Trinidad. — hilareia subsp. nov. has 
a reduced more irregular yellowish-brown zone of the forewings and more intensely and beautifully coffee- 
brown stripes on the under surface of both the wings. Peru, Tarapoto, and from the Upper Amazon. — mamaea 
subsp. nov. is found in Mato-Grosso. The reduction of the yellowish and white bands of the upper surface is still 
increased as well as the darkening and reduction of all the markings on the under surface. 
A. erymanthis resembles A. ewboea and fabricia (106d), but the white stripes of the hindwings are 
still more reduced and terminating in the anal direction into a sharp point in the Central American type. A 
very rare species of which only two forms are known to me: erymanthis Godm. and Salv. being on the forewings 
most similar to A. boeotia (106 c), the white band of the hindwings being, however, much narrower. Under 
surface most approximate to that of A. aethalia (106d). Nicaragua, Costa Rica. — adstricta subsp. nov. The 
light yellowish-brown zone of the forewings broader, proximally running straighter than in erymanthis. The 
white area of the hindwings reduced to a short, extremely narrow, small band terminating at the third median 
and, thereby, resembling A. ernestina (106 b). Colombia. Type in the Museum of Geneva. 
A. jordani is an entirely isolated species. Its size very much approximates the small A. boeotia 
Fidr. with which also the position of the reddish-yellow zone agrees the most. The peculiarly bulging stripes 
of the hindwings, however, distinguishes it from all the allies. Another characteristic mark is especially a black 
spot in the anal angle of the under surface of the forewings not seen in any of the allies. Two geographically - 
separated branches: jordani subsp. nov. (106d) with remarkably broad bands on the under surface. Peru. — 
ernestina subsp. nov. (106 b). As to the habitus, smaller than jordani, the ochreous median band of the fore- 
wings very much darkened, the white median area of the hindwings shorter and narrower, but bordered in the 
analangle by a much broader and more distinct dark-blue zone. Under surface: white marking reduced, more 
faded, forewings with a more extensive yellowish postdiscal region. The brown longitudinal band of the hind- 
wing so characteristic of jordani nearly again as broad as in the Peruvian branch. Bolivia, Mapiri. Type in the 
collection FRUHSTORFER. A 3 somewhat deviating from it, from Bolivia. San-Ernesto at an altitude of 1000 m, 
below the 68th degree of western and 15th degree of southern latitude. Collected in September 1900, in the 
Tring-Museum *). 
A. erotia is considered to be one of the commonest species of the Continent. It is not able to offer 
great resistance to climatic influences, so that it is divided into a number of territorial forms, and besides, it seems 
to be subject to metagenesis, for there exist enormous specimens with large white spots beneath (permagna) 
beside relatively small ones being only little checkered beneath. There seems to exist also a form of condition 
independent of time and locality with beginning or advanced white embedment at the end of the yellowish- 
brown median band in the submedian region of the forewings. The most characteristic under surface is con- 
spicuous by the great number of isolated silvery white spots and the purely white subbasal bands of the hind- 
wings. According to the season and the habitat of the butterflies, the white submarginal maculae are covered 
by reddish-brown ones (Colombia), or they increase even in size (Surinam, Cayenne) or they are faded (Vene- 
zuela). The tegumen is most plainly shaped with the usual, rather sharp point of the uncus, valve with a 
roundish clunicula (with a dentiform dorsal appendage), exteriorly obtuse, nearly entirely unarmed. — deleta 
subsp. nov. (106 e). The yellowish longitudinal band is in the anal direction, near the submedian, brightened 
up with white, also otherwise lighter than the following races. The three subapical maculae uncommonly strong; 

*) Clasping organs sharply differing from those of A. erotia, but without any special marks. Clunicula higher than 
in A. erotia.
