346 On the Nymphalinse of the Amazon Valley. 
third of the fore wing and the whole abdominal limb of the hind wing 
being deep black in both sexes. 
This is a local form of the same stock as M. Deidamia, entirely 
replacing the latter form in the western parts of the Amazons valley, 
beginning at Villa Nova, near the mouth of the Madeira. In my 
own collection and that of the British Museum. 
180. Morpho Uraneis, n. sp. 
3. Expanse 5”. Fore wing with the costa strongly arched, apex 
pointed, outer margin slightly and regularly incurved, hind angle distinct 
but obtuse: hind wing regularly rounded outwards, and not produced at 
the anal angle, abdominal edge straight. Above, of a pale satiny or 
silvery blue, with the apex of the fore wing black, the black part deeply 
trisinuate on its inner edge; two whitish spots on the costa beyond the 
cell of the fore wing: hind wing with two very narrow black spots at 
the termination of the abdominal nervure and the first median branch. 
Beneath, pale tawny buff, with several transverse whitish belts, two of 
which, broader and more distinct than the rest, cross the cells of both 
wings. Fore wing with three, and hind wing with two ocelli, having 
white pupils and orange-tawny irides, edged on each side with black. 
Anal angle of the hind wing with two black spots in the same situation 
as those of the upper side, but surmounted by two short blackish lines. 
This extremely beautiful and peculiar species of Morpho was not 
an uncommon insect in the forest of Ega, at the commencement of 
the rainy season, from December to April; but its extremely lofty 
flight prevented me from obtaining more than two examples, one of 
which is now in the British Museum collection, and one in my own. 
It resembles somewhat M. Eugenia (E. Deyrolle, Ann. Soc. Ent. Fr. 
1860, p. 209) of Cayenne, but differs in the rounded form of the 
hind wing and in other particulars. 
181. Morpho Rhetenor, Cramer. 
Papilio Rhetenor, Cramer, 15 4, B, 3. 
Andromachus, Cramer, 56 A,B, 2. 
Found throughout the Amazons region, from Pard to Ega. Its 
flight is very lofty, so that it is extremely difficult to capture. It 
delights in the broad alleys of the forest, sailing along them from 
end to end at a height of from 20 to 50 feet from the ground.
