have therefore retained it under the term iodura.

Habitat. Pacific side of Nicaragua; Realjo ?

The Erythronote are nearly allied to the Pyrrhophene. As in that genus, the sexes are alike in their colouring.
The species are much more circumscribed in their habitat, being almost confined to Venezuela and the countries
immediately adjoining.

The oldest-known species, which I have called antiqua, appears to be subject to much variation in its colour
and markings; but, as I stated in my account of that species, I have questioned the propriety of their separation

until we are better acquainted with them.

Habitat. Trinidad, Tobago, and Venezuela.
The birds from Tobago are very much larger than those from Trinidad; and some of the specimens from
Venezuela have the under tail-coverts wholly chestnut ; I should have considered this indicative of another species
