cell of the fore wing. The fore wing has also two whitish spots 
near the middle of the outer border, in place of the obscure whitish 
streak of the Mexican specimens: beneath, the red belt is broader 
and much less lunulated than in the typical form. As only a single 
example was found, I am unable to say whether these differences are 
constant, and so refrain from treating it as a distinct form with 
separate name.

Para; rare, in moist hollows in the virgin forest, flying mostly 
near the tops of trees. Pard examples of the male agree precisely 
in breadth of white belt, &c., with the Guiana type, as figured by 
Cramer. I have specimens also from the Isthmus of Panama which 
scarcely differ from the Surinam type, and a female example from 
South Brazil agreeing precisely with the same sex of the Para form.

do 2. Expanse 2” 8’. Closely allied to P. Tiphus. Wings similar in 
shape; but fore wing rather more pointed, with outer margin more incurved. 
Black, a common, broad, pale greenish-white discoidal belt reaching on 
the fore wing to the base of the first median branch, and on the hind 
wing covering more than half the cell. To this succeeds, on the fore 
wing, a broad oval spot, of the same hue, and a subapical whiter spot, 
conspicuous in both sexes. The black outer borders have, in the female 
and in some examples of the male, a row of obscure whitish spots. 
Beneath: the form and extent of the red lines same as in P. Tiphus; but 
the row of semicircular white spots on the outer borders are not clearly 
defined and semicircular as in that species. 
Upper Amazons, Ega, and St. Paulo; common. These differences 
are constant in all the specimens I obtained of P. Amphiro, which 
therefore constitutes a well-defined local variety or race of the 
P. Tiphus stock. It is curious that such a form should exist in the 
middle of the geographical area of the true Ziphus, which, as before 
remarked, extends from Panama to South Brazil.

A common insect in the forest over the whole Amazons region. 
It conforms to the Surinam type more closely on the Upper Amazons
