hairs as in P. iphidamas, &c, but the fold is less complex (Tab. LXV. fig. 8). The 

 foliate appendage of the fore tibia is placed a little nearer the proximal than the 

 distal end of that joint; the harpe of the male ends in a single point which falls near 

 the extremity of the valve, and the whole harpe lies along the upper rather than the 

 lower edge of the valve, and there is no projection anywhere along its lower edge (see 

 Tab. LXV. fig. 8 a). The secondaries have no opalescent gloss. 



This group is chiefly found in Brazil, where six or seven species occur. The two 

 following species are peculiar to our country, and there is a very remarkable one 

 found in the island of Cuba.

Professor Westwood described this species from a specimen from Mexico l , and it is 

 now known to be widely spread in that country, chiefly, but not exclusively, on the Pacific 

 side of the Cordillera. Here it extends from the neighbourhood of Mazatlan south- 

 wards. In Guatemala, too, it is usually found on the side of the mountains sloping 

 towards the Pacific, and, though chiefly a denizen of the lowlands, was met with as 

 high as 5000 feet on the slopes of the Volcan de Santa Maria. On the eastern side 

 of the Cordillera it is much less common, but we met with it ourselves in the valley 

 of the Motagua and in other valleys of Central Guatemala. 



Papilio montezuma has no near ally in our region, unless it be P. alopius from the 

 Sierra Madre of Durango. 



In South America P. perrhebus of Brazil and the Argentine Republic is probably 

 nearest to it, as Professor Westwood has already pointed out \
