wing ; the bases of the costal borders of both wings are also silky ochreous 
white. The wings haye numerous black spots and crooked lines similar 
to those of P. Demodice, but much more angular; the hind wing has two 
large ocelli and a space between them, and the disk speckled with brown 
on a pale ground. 
Of this species I have two examples, exactly similar—one taken 
at Para, and one at St. Paulo, on the Upper Amazons*.

Papilio Pheridamas, Cram. 158 A, B. 
This elegant species belongs to the section the males of which have 
a stellate fascicle of pale hairs on the abdominal border of the hind 
wings. It is generally distributed throughout the Amazons region, 
but not common anywhere. 
145. Prepona Meander, Cramer. 
Papilio Meander, Cramer, 12 A, B. 
The insect figured by Cramer, in the place here quoted, seems to 
me to belong to a different species from the P. Amphimachus of 
Fabricius, with which it has been considered by many authors as 
identical. In P. Meander the outer halves of the wings beneath are 
dark brown, with a minute white subcostal spot on the hind wings. 
The Fabrician phrases, “ale... subtus... postice obscure cineree ; 
posticis puncto majori albicante et septem parvis brunneis pupilla 
alba,’ does not suit the Cramerian species, but applies exactly to the 
one to which I confine the name Amphimachus. P. Meander differs 
* Prepona Pylene, Hewitson (Exot. Butt. Prep. f. 3. 5), is another species of 
the Demodice group, and the following makes a fifth form of the same subsection 
of the genus :— 
Prepona Gnorima. 
¢@. Same size and form as P. Demodice, the fore-wing apex being greatly pro- 
duced, as in that species, and the outer margin strongly incurved. Blue belt only 
one-half the width of that of P. Demodice ; costal spots absent, but inner side of 
the belt of fore wing glossed with rich dark blue extending to the costa. The 
ground-colour of the wings is much lighter than in P. Demodice; consequently 
the hind-wing ocelli shine through to the upper surface. Beneath, similar to 
P. Demodice, the basal halves of the wings being whitish, and the outer halves 
brown; there is, however, no tawny patch on the fore wing, and the angulated 
black line which crosses the fore wing beyond the cell is not continuous, and the 
separate black lines of which it is composed have each on their external sides a 
whitish spot. The irregularly curved black line towards the outer margin of the 
same wing is connected with the exterior row of oval rings, so as to form with 
them a single line with loop-like projections.
