portion of the cell, and, extending thence towards the pos- 

 terior angle, is cut by the second and third median nervures. 

 Beneath browner, the margin of the brick-red band of the an- 

 terior Avings black, the apical portion of the same wings and 

 the whole surface of the posterior wings thinly covered with 

 yellowish scales. Head and antennge black.

This fine species is quite unlike any other known member 

 of the genus. It must be placed with P. Zagreus^ Dby., and 

 its allies. Instead, however, of assuming the garb of Lycorea, 

 it takes that of the underside of Euterpe CalUnicej Feld. 



25. Papilio xanthopleura. 



6 . 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. Antennas 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.

Allied to P. Corcebus, Feld. (Voy. Nov. t. 13. f. «, b), but 

 abundantly distinct. The remarkable yellow patch on either 

 side of the abdomen distinguish this fine species from every
