This is the common species in the interior of the country. It is very abundant at Bga 
on the Upper Amazons, where D. Brippus did not occur.

The six described species of this genus differ from each other by such slight characters 
(small differences in colours, and in the arrangement of the pattern on the Winn's 
O^J utm o 
the only points which distinguish them), that they might fairly be considered as varieties 
of one only. I have not yet seen specimens, however, which connect all the forms 
together, and these are mostly the products of different geograp] i ical areas ; it will be 
more convenient therefore to treat them independently, than to combine them under the 
head of one polymorphic species. A good collection of specimens from all parts of the 
area of distribution of the genus would here be very instructive. We should then be able 
to ascertain the metropolis and probable area of origination of each of the various forms. 
I have seen only L. Halia in collections from S.E. Brazil. L. atergatis is peculiar to 
Columbia and the Upper Amazon region ; but a striking variety of it prevails over the 
type in this last-mentioned district, and another, L. Pales (Pelder), occurs on the Rio 
Negro. L. Cleobcea (which is scarcely more different from L. atergatis than the just- 
mentioned L. atergatis, var., is from its type) is reputed to occur in the West India Islands. 
At Para three forms, including L. Halia, are found together ; and here some intermediate 
varieties occur, making it probable that the segregation of the quasi-species is not in 
that district complete. 
1. Lycorea Ceres, Cramer. 
Papilio Ceres, Cramer, Pap. Exot. t. 90. f. A. 
This species occurs in the Amazon region at Para, and on the banks of the Tapajos. 
It is also an inhabitant of Surinam. Cramer's figure is made from an example rather 
aberrant in the markings of the hind wings ; otherwise it agrees very well with the 
specimens I have before me. I have a variety from Para which connects this form with 
L. Halia. 
2. Lycorea Pasinttntia, Cramer. 
Papilo Pasinuntia, Cram. Pap. Exot. t. 316, A, B, C. 
This form occurs throughout the whole of the Amazon region, from 48° to 70° W. 
long. The extreme western examples, found at St. Paulo on the Upper Amazons, 
show a change of colour in the yellow irregular belt of the fore wing, which has acquired 
the same orange-tawny shade as the rest of the wing. The same substitution of colour
