knowledge. This and the preceding species inhabit open sunny 

 places in the forest or on its borders ; they are bold and rapid fliers. 

 The males resort to moist places on the banks of streams, the females 

 frequent flowers. They resemble, in some features of structure and 

 coloration, the Ornithopterse of South-eastern Asia ; and are con- 

 nected by affinity, through P. Pliilenor of North America, with the 

 Machaon group of Papiliones.

A widely distributed species ; foimd thi'oughout the Amazon region 

 in cultivated places, frequenting flowers. In the West India Islands 

 it is somewhat modified, — in Chili much more strongly so, the form 

 from that country ranking as a distinct species, viz. P. Arcliidamas, 

 Boisd.

Upper Amazons, and descending the river as far down as Villa 

 Nova. The male only has been found ; the female probably is con- 

 fined to the shades of the forest, where the species of Heliconia, 

 which it mimics in colours, is also found : the male I have some- 

 times observed flying about the summits of the lower trees, although 

 it is most frequently seen on the margins of streams, in company 

 with P. Belus and allies.

P. Ariaratlies (type) is found at Para ; in ascending the river it 

 becomes modified. On the Rio Negro the var. Evagoras prevails (as it 

 seems to do also in Venezuela) ; it is also found at Ega, on the Upper 

 Amazons. At the latter place Cyamon is the most prevalent form. 

 Gayi is an extreme variety of the S found at Ega, and near Cusco, 

 between Pern and Bolivia. The true Ilus of Fabricius is quite a 

 different species, inhabiting VenezAiela, and probably identical with 

 the one recently published by Dr. Felder as P. Hostiliris (Lep. Nov. 

 Columbiae, no. 5).
