black border, dentated in the middle, which continues much diminished in 
breadth to the hind angle, and is ornamented near the apex with a clear- 
white rounded spot, sometimes accompanied by a second smaller one. 
Hind wings with the outer margin rounded and slightly festooned, the 
point at the end of the 3rd median branch being more prominent than the 
rest, especially in the female: above rich tawny, with a submarginal row 
of short blackish streaks, and two small black spots near the anal angle. 
Beneath: the wings are a little paler than above, and are crossed by a 
rufous bar reaching from the costa to the anal angle, besides a submar- 
ginal line (strongly flexuous) on the fore wings, and on the hind wings a 
second inner line of a rufous hue; all the wings have near their apices 
two bluish ocelli with large white pupils, the hind pair having, besides, 
two smaller ones near their anal angle. Body above tawny brown; an- 
tenn black, ringed with white. The female does not differ in colours 
from the male. 
Varies in the dusky and rufous lines, both of the under surface of the 
wings and the upper surface of the hind pair, being accompanied by lines 
or streaks of a plumbageous hue. 
This pretty species was met with on the Upper Amazons, from 
Ega to St. Paulo, in sunny places in the forest, settling on pathways. 
It is allied to NV. Canthara (Dbldy.) of Venezuela: the latter is said 
by Doubleday, in his very brief and insufficient description (Dbldy. & 
Hewits. Gen. p. 226), to have the flexuous lines of the under surface 
bordered by plumbageous lines ; but it is possible the species varies 
in this respect, as does our JN. sylvestris. According to specimens 
from Bogota which I have seen, NV. Canthara differs from N. sylvestris 
in wanting the clear-white spot near the apex of the anterior wings. 
Genus Petia, Dbldy. D. & H. Gen. p. 229. 
This small genus is distinguished from Nica chiefly by the first 
and second fore-wing subcostal branches being amalgamated for the 
greater part of their course.

Found in the same situations as Nica sylvestris. It has, however, 
a wider range, being distributed throughout the whole of the Amazons 
region and Guiana. 
Genus Catiicorz, Dbldy. D. & H. Gen. p. 237. 
The present genus is connected, through Perisama and Cybdelis 
(genera not found in the Amazons region), with Hunica, and through 
Catagramma with the Callithee. It is very closely allied to Cata- 
gramma ; but differs in its eyes being hairy, instead of naked, and in 
its neuration; both first and second subcostal branches of the fore
