allies have broader wings, and are of a pale silvery blue, 

 becoming almost white in some species, such as i\J. Poly- 

 pliemus. They are about five or six inches across. M. JE^ga 

 is a small species, about three inches across; the male is of 

 a rich metallic blue, vvith two white spots on the costa near 

 the tip of the fore wings ; the hind wings are pointed, and 

 almost tailed at the anal angle ; the female is dull orange, 

 with one white spot near the tip, and the hind margins are 

 brown, spotted with orange. M. Sulkowfikyi is rather 

 larger and of a similar shape, but of a paler, more violet- 

 blue, showing different colours in different lights ; the bands 

 and eyes of the u, s. show through, especially in the female, 

 which is bordered with brown on the fore wings, and has 

 alternate narrow marginal bands of yellow and brown on the 

 hind wings; the tip is brown in the male, and the anal angle 

 is brown, with three small orange spots, in both sexes. The 

 most splendid deep metallic blue of the whole genus is seen 

 in the males of Cypris and Rhetenor. The male of the 

 former has two rows of white spots, the inner forming a band 

 on the hind wings; and the male of the latter has no white. 

 The female of Cypris is dimorphic, being either blue or 

 orange; that of Rhetenor is orange. These species measure 

 about four and a half to six inches across. The species 

 allied to iVIenelaus and Achilles are of a much less changeable 

 colour, and have broader wings than those last mentioned. 

 Menelaus is of a rich purplish blue, and measures five or six 

 inches across ; the margins are brown towards the tips of the 

 fore wings, with a white spot in the male ; in the female the 

 borders are broader and spotted with white. Achilles, and 

 the numerous species or varieties allied to it, vary from four 

 to six inches across, and are brown, with a blue band across 

 the middle of all the wings, varying nuich in breadth and 

 intensity, and sometimes extending nearly to the base; the 

 tips in the male and the hind margins in the female are 

 generally more or less spotted with white. 



The long-winged species of Morphu have an extremely 

 lofty flight, sailing about the tops of the trees or along the 

 alleys of the forest, from twenty to one hundred feet from the 

 ground. Hence, with the exception of the New Granadan 

 species (M. Cypris, Sulkowskyi, &c.), which are taken with 

 long nets among the precipices of the Andes, and which may
