wings and in other minor points. Since describing it, I have carefully 
compared my Amazonian specimens with the figure given by Cramer 
as representing the Papilio Iphicla of Linnzus, and find them to 
agree very closely, except that Cramer’s figure does not give sufficient 
depth to the green tinge of the pale belt of the wings. Cramer mis- 
took his insect for the Linnean Jphicla, which is represented in 
Clerck’s ‘ Icones,’ and is quite a distinct species. 
127. Heterochroa Paraéna, un. sp. 
Q. Expanse 2” 9’, Similar, above, to H. Serpa, Boisd. (Species Gén. 
pl. 8. f.4. Shape of the wings the same, and white belt of the same hue ; 
the latter, however, extends only to the second branch of the median 
nervure, and the inner side of the orange spot covers most of the space 
between the second and third median branches, which in H. Serpa is 
occupied by the termination of the white belt. The cell of the fore wing 
has a red belt, and a streak of the same colour at the base. The hind 
wing has three blackish stripes along the brown outer limb, the inner 
one, or that which borders the white belt, being of great width—four times 
as wide as the middle stripe. Beneath, the characteristic marks of the 
cell are the same as in HZ. Serpa and H. Celerio, except that there is no red 
belt across the end of the cell. The black streak which lies beyond the 
cell is very broad, and encloses two white spots. The outer border of the 
fore wing has indistinct dingy-white spots, and a thin, dusky submarginal 
line, but there are no longitudinal dusky streaks between the nervures. 
Hind wing of the same general pattern as in H. Serpa and H. Celerio; the 
rufous belts are of a darker rufous hue, and their black edgings are broad, 
especially the inner edging of the outer belt, which is of great width. 
The outer limb of the wing is greyish white, and the nervures not tinged 
with black. 
This species occurred at Para only.

Papilio Iphicla, Linn. Syst. Nat. ii. 784, n. 181. 
, Clerck, Icones, t. 41. f. 3. 
A common insect on the banks of the Upper Amazons and the 
Tapajos, settling in moist places on the banks of streams ; also seen 
flying about the summits of trees in sunny parts of the forest. 
129. Heterochoa Basilea, Cramer. 
Papilio Basilea, Cram. 188 D. 
This species is very closely allied to H. Iphicla of Linnzus. It 
differs, on the under side, in the grey markings at the end of the 
fore-wing cell consisting of a single row of three wedge-shaped
