98 Mr. W. C. Hewitson's Descriptions 



margin to the first median nervule ; nearer to the base than the 

 outer margin. 



Posterior wing with a rather large rounded patch of dark crim- 

 son, which, occupying the lower half of the cell, and extending 

 beyond it, is cut into five unequal portions by the nervures ; the 

 outer margin with very distinct white lunules. 



Under side lighter than above, of a uniform black, except 

 the marginal lunules, and a band of white, slightly tinted with red, 

 which does not occupy the same position as the crimson patch 

 above, but is placed half-way between the end of the cell, and 

 the outer margin, and extends, from the abdominal fold where it is 

 widest, more than half-way across the wing, cut into four unequal 

 portions by the nervures j the outer portion clouded and indis- 

 tinct. Expan. -3 t 3 q inch. 



This species is most nearly allied to P. Vertumnus. The green 

 patch is much more beautiful, and the red one without its irride- 

 scence ; and though in a different position above, occupies nearly 

 the same below. 



It is in my own collection, and was captured by Mr. Bates on 

 the Amazon. 



Papilio Columbus. (PI. X. fig. 1.) 



Upper side cream colour, the outer margin of the wings and 

 a large space at the apex of the anterior one black, the posterior 

 wing dentated, with a narrow linear tail of moderate length. 



Anterior wing with the costa at the base bordered with black, 

 and forming part of a triangular belt of black, which crosses the 

 middle of the cell at the costa and at right angles with it ; just 

 beyond the end of the cell upon the black is a short line of 

 white. 



On the posterior wing the black margin is marked with several 

 irregular white spots, and from its inner margin rise three upright 

 lines of black, which are crossed at their points by another line 

 of black, one end of which runs to the middle of the upper margin 

 of the wing, the other is joined to a black spot, which occupies 

 the anal angle, and encircles a lunular spot of scarlet. 



Under side does not differ from above, except that the mar- 

 gin of the anterior wing, and the adjoining part of that of the 

 posterior wing, are lighter ; that the black lines on the posterior 

 wing are more distinct, and that some of the nervures are also 

 black. Expan. 3 T 3 ^ inch. 



In my own collection from the river Amazon. 



This species is nearly allied to P. Dolicaon.
