of the Amazon Valley, 185 
the Eetime and Pandore, whose wings are partly open, partly closed, 
when they settle, and the Ageroniw, which extend their wings flat on 
the trunks of trees. These latter are most peculiarly coloured, and 
differ much from all other Nymphaline in their habits, as will be 
familiar to all readers of travels in Brazil. Lastly, the fifth group is 
composed of numerous genera and species closely related to our purple 
Emperor, which also live habitually in the forest, but have a most 
rapid flight, and settle frequently on outstretched branches or foliage. 
They are all bold creatures, not moving from their perches until 
driven off, and, even when scared away, returning to them after a 
few minutes’ absence, dashing meanwhile with arrowy swiftness along 
the forest-alleys. Such are the species of Agrias, the most beautiful 
genus in the whole subfamily ; the Prepone, the Siderones, and the 
Paphie, of all of which there are numerous species in the Amazons 
region, some of them extremely common. 
A few words may be said, in conclusion, regarding the habits of the 
species of the Morpho group. These have no resemblance whatever 
to those of any of the genera of Nymphaline ; but what lessens the 
value, in a classificatory sense, of this distinction is, that the Vorphos 
differ quite as much amongst themselves as they do from the Nym- 
phaline. They are all, it is true, creatures of the great forest; but 
whilst some have a flapping and undulating flight, straight onward 
along the alleys of the forest, and near the ground, others are never 
seen, except steadily gliding with outstretched wings from 20 to 100 
feet above the ground, where they move across sunny spaces between 
the crowns of the taller trees. The low-flyers are M. Achilles, M, 
Deidamia, M. Menelaus, and their subspecies; the high-flyers, 1. 
Uraneis, M. Rhetenor, M. Telemachus, M. Cisseis, and M. Hecuba : 
the three latter of which are very seldom observed to flap their wings 
as they lazily fly along, whilst Uraneis and Ehetenor do so at every 
dozen or so yards of their course. Achilles and its allies, moreover, 
settle frequently on the ground to suck the juices from fallen fruit, in 
the company of Temenis Ariadne, Nica sylvestris, and other Nym- 
phaline, besides Satyridz of the genera Antirrhea, Taygetis, Hetera, 
&e.; but the members of the other section of the Morphos never de- 
scend to the ground. Indeed it is only very early on calm sunny 
mornings and towards midday, just before a thunderstorm, that they 
are tempted or forced to descend from their great elevation.
