occurs in several other species of Heliconidse, found in that locality— a curious result of pe 
culiar local conditions. Cramer figures a slight variety as the c? of the species (fig. A) 
3. Lycorea Halia, Hiibner. 
Eueides Halia, Hiibner, Exot. Schmett. 
Found in company with L. Ceres and L. Pasmimtia at Para. As I have before 
remarked, this is the form of Lycorea which prevails in S.E. Brazil. A variety, found 
also at Para, connects it with L. Ceres, the chief Guianian form, and suggests the 
conclusion that both the extreme local races or species were one and the same at not a 
very distant period of time.

L. atergatis, Doubled, and Hewits. Gen. Diurn. Lep. pi. 16. f. 1. 
The figure here quoted was made from a Venezuelan specimen. I did not find the 
species on the Lower Amazons ; but it was the most abundant form of the genus at Ega, 
on the upper river. Many of the individuals there occurring, however, form a strongly 
marked variety, in which the ground-colour is dark brown, suffused more or less with 
blackish. Further to the west of Ega, this variety is the prevailing form. 
Genus Ituna, Doubleday. 
Doubled, and Hewits. Gen. Diurn. Lep. p. 113. 
The species of this genus, like those of Lycorea, seem to be all geographical forms of 
one only. But in this instance the segregation of races is complete, whilst in Lycorea 
we have seen it to be in many of the forms only in process. Three Itun<e are known : 
one, I. Lamyra, Latr., occurs in New Granada ; the second, I. Ilione, Cram., inhabits 
Guiana and, I believe, Brazil, along the Atlantic coast ; the third, L Fhenarete, Dbld., is 
peculiar to Bolivia and the Upper Amazons. All three are tolerably distinct in colours 
and markings.

Genus Methona, Doubleday.

This genus, which is so closely allied to the following ( Thyridia) that the species of 
both have always been confounded, is distinguished from it by structural characters, viz. 
the neuration of the hind wings and the form of the male fore legs, which are of great 
systematic importance in another part of this family, but here can scarcely be considered 
even of generic value. The internal (abdominal) nervure of the hind wing is long, and
