portion of the cell, and, extending thence towards the pos- 
terlor angle, is cut by the second and third median nervures. 
Beneath browner, the margin of the brick-red band of the an- 
terior wings black, the apical portion of the same wings and 
the whole surface of the posterior wings thinly covered with 
yellowish scales. Head and antenne black.

This fine species is quite unlike any other known member 
of the genus. It must be placed with P. Zagreus, Dby., and 
its ales. Instead, however, of assuming the garb of Lycorea, 
it takes that of the underside of Huterpe Callinice, Feld. 
25. Papilio xanthopleura. 
g. Exp. 5°80. Anterior wings elongated, acute, the outer 
margin only slightly concave; outer margin of the posterior 
wings deeply indented, the third branch of the median nervure 
bearing the longest projection; inner margin very hairy: 
black, each space between the nervules terminating at the 
outer margin of the anterior wings with an elongated, indis- 
tinct greenish line; the end of the cell of the posterior wings 
followed by four radiating patches, separated only by the ner- 
vules, bluish green; an oval spot of the same colour between 
the branches of the subcostal nervure and a similar triangular 
spot near the anal angle; a row of seven similarly coloured 
spots surrounds the wing near the margin, the indentations of 
which are narrowly edged with white; the spot nearest the 
anterior angle nearly white. Underside brown, the apex of the 
anterior wings paler; indistinct yellow markings about the 
end of the cell, and others, rather greener, near the posterior 
angle, those nearest the margin being divided by the median 
fold: posterior wings with a row of seven submarginal brick- 
red spots edged with black ; above the spot, at the anal angle, 
is a subtriangular yellow mark. Antenne black; a yellow 
spot behind the eye, another on either side of the origin of 
the maxillary palpi, others of the same colour on either side 
of the prothorax, the base of the wings, and the middle of the 
front part of the thorax ; abdomen black, dark brown beneath, 
with a large yellow patch on either side. 
Hab. Eastern Peru, Lower Huallaga (Bartlett).

Allied to P. Corebus, Feld. (Voy. Nov. t. 13. f. a, 6), but 
abundantly distinct. The remarkable yellow patch on either 
side of the abdomen distinguish this fine species from every
