I took one example only of this handsome species, in the heart of 
the forest at Ega, hovering about a low tree in a sunny opening. 
85. Olina Emilia, Cramer. 
Papilio Emilia, Cram. 223 8, F. 
Common in thinned parts of the forest throughout the Amazons 
region. The examples taken near Pard agree pretty closely with the 
Surinam type as figured by Cramer; but on the Upper Amazons it 
varies considerably, the subapical white spots becoming a continuous 
belt, and the white stripe of the hind wings, in some examples, dis- 
appearing; the size also is inclined to be larger. This form has 
been described (as a geographical variety) by Dr. Felder under the 
name of O. Cecilia. It is not, however, a well-defined local form or 
race, as examples conformable to the type are found mingled with it 
in the same parts of the forest. The species can be said only to show 
a tendency to the segregation of a race in the region of the Upper 
Amazons. Dr. Felder’s specimens came from the Upper Rio Negro. 
Genus Cysrrnevra (Boisd.), 
Westw. in Doubld. & Hewits. Gen. Diurn. Lep. p. 406. 
The mode of flight of the species constituting this genus is similar 
to that of the Olin, near to which Cystinewra is placed, in the 
family Eurytelide, by Westwood. 
86. Cystineura Tocantina, n. sp. 
@. Expanse 1” 10’... Very similar in shape and markings, and almost 
identical in colours, with C. Hypermnestra, Hiibner. Differs above in want- 
ing the dark-brown, festooned marginal line of hind wing, and beneath in 
the pale marginal lunules of the hind wing not being bordered on either 
side with a dark line. The central dark belt of the hind wing is rather 
broader, and the succeeding white belt much less macular, than in C. Hy- 
permnestra. The outer border of the same wing, as well as the white 
macular belt, have no trace of dark edging. 
Taken on the borders of woods, at Cametd, on the banks of the 
river Tocantins. 
Genus Pyrruoeyra (Hubner), 
Westwood, in Doubld. & Hewits. Gen. Diurn. Lep. p. 252, 
This distinct and at present well-defined genus seems to be more 
nearly allied to Cystinewra and Olina than any other of the admitted 
groups of Nymphalidz. The bases of the fore-wing costal and me- 
dian nervures are swollen, although not to the extent beheld in the 
genera which formerly constituted the family Eurytelide. The palpi
