61. Antigonis Pharsalia, Hewits. 
Cybdelis Pharsalia, Hewits. Exot. Butt. Cybd. f. 14, 16. 
Found only at Ega; the males frequenting the moist sandy and 
muddy shores of the river, and mingling with the crowd of Eunice. 
62. Antigonis Felderi, n.sp. (Pl. X. figs. 25,32.) 
3. Same size and shape as A. Pharsalia. Above of a uniform light 
pinkish blue or mawve colour, fringe white: fore wing with three white 
spots arranged in triangle on the disk. Beneath: fore wing ashy, tip 
paler, with two dots and a submarginal line black, and costa near the base 
streaked with dusky; beyond the middle a broad black belt, with two large 
spots corresponding with the outer two of the upper surface: hind wing 
ashy white, variegated throughout with a multitude of short dusky streaks. 
Q. Same shape asthe ¢. Above, coloured like the females of Hunica ; 
light brown, basal parts sprinkled with grey atoms, and apical half of fore 
wing black, with four large white spots arranged obliquely in quadrangle. 
Beneath: fore wing ashy, tip paler, with two black dots, and a submarginal 
line black, and costa near the base streaked with dusky ; beyond the middle 
a broad black belt, with two large spots corresponding to the outer two of 
the upper surface, preceded outside the black belt by two others corre- 
sponding with the inner two: hind wing ashy white, variegated with a 
multitude of short dusky streaks. 
This elegant species entirely replaces A. Pharsalia at St. Paulo, 
400 miles to the west of Ega. It delights to settle on the moist 
margins of brooks in the forest, and is of very nimble flight.

63. Callithea Sapphira, Hiibn. Samml. Ex. Schm. 
This most richly coloured butterfly appears to be confined in its 
range to the dry woods near Santarem, on the eastern side of the 
mouth of the Tapajos. Further westward I never saw a specimen ; 
and to the south its area appears to be equally limited, as I did not 
find it further than twenty miles from the mouth of the river. It 
may, however, extend over the country to the east, that part of this 
region not having yet been explored. The species appears to have 
two broods in the course of the year, the first in October, and the 
second in February and March ; but the first fails if the season be a 
dry one. In Marchit abounds, at least in some years, the woods posi- 
tively swarming with the superbly adorned creatures, the two sexes 
being in about equal number, and the glowing sapphire and orange 
liveries imparting wonderful liveliness to the sylvan scenes. When 
very abundant, especially in gleamy showery weather, they issue from
