OF THE AMAZON VALLEY. 
r.m 
The area of distribution of S. Vesta embraces the lesser areas of II. Melpomene and 
H. Thelxiope. As intermediate forms connect it with II. Melpomene, there can be no 
doubt that it is descended from the same stock as that species ; but having dberged 
more widely, it is not readily seen to be a modification of it, like II. Thelxiope. It may 
be the oldest-created of this cluster of imperfectly segregated species.

Migonitis Burneyi, Hiibn. Zutr'age, f. 401, 402. 
This fine, large, robust species belongs to the same group as II. Melpomene, &c. It 
seems to be confined, like R. Thelxiope, to the forest plains of the Amazons ; it is not, 
however, a common insect, but is restricted to certain localities. Its strong, bold flight 
distinguishes it from all other species of Ueliconius, when on the wing. Many individual s 
of both sexes have the hind winffs black, except a patch of red at the base.

This resembles much S. Burneyi in size and general appearance; it seems, however, 
to be a perfectly distinct species, recognizable by the glossy light-brown lute with paler 
streaks between the nervures, of the under surface of the wings. The hind wing beneath 
has a red streak near the abdominal edge, and there is a yellow spot on the costa at th, 
base. It is a rare species : I took it at Para : it is found also at Cayenne, where S. B**W 
appears not to occur. My specimens differ from the one figured by Cramer, m the derign 
of the upper surface of the hind wing, the red colour of the basal half bemg continued >n 
a series of eight short, wedge-shaped streaks into the broad, black marginal half of the 
wing. 
18. Heliconitjs Acede, Hiibner. 
Migonitis Aatde, Hiibn. Zutrage, f. 12? 
Heliconia 
The antenna, in this species are much shorter than in the JleUconu j «e , and 
more thickly clavate. It appears to be confined to the Amazon -S">n and Gu, n. In 
Guiana (Demerara and Cayenne) a species is found* which closely resemUes .t m shape 
and colours, but differs in having slender antenna,, like the typical SeUcon , , .
