Hewitson's types of this species were from Ega on the Upper Amazons, and were 

 probably collected by Bates 1 . We now know that its range extends over a very wide 

 area of the Neotropical region, from North-western Mexico to South Brazil. Individual 

 variation chiefly affects the white band on the secondaries beneath, as regards the 

 definition of its outer margin ; sometimes this is fairly well defined, at others it blends 

 with the light colouring of the outer portion of the wings. The tint of the apical 

 portion of the primaries and also of the secondaries varies a good deal from olive to 

 purple ; this is probably due very much to the age of the specimen and the action of 

 light. 



The range in altitude of E. asander in our country extends from the sea-level to 

 about 5000 feet. 



The male genitalia differ from those of E. exadeus chiefly in the form of the harpes ; 

 these are rounded at the end and have a dorsal cleft, on each side of which is a 

 cluster of strong serrations, a spine directed upwards lies just inside the end, and a 

 strongly serrated lobe occupies the end of the disc. (See Tab. LXXVII. fig. 4.) 



PEOTEIDES.

In general appearance P. idas, the type of Proteides, resembles Epargyreus exadeus, 

 and the neuration of the wings is very similar. On the underside the character of the 

 markings of the secondaries of P. idas differs from that of E. exadeus ; the primaries 

 have no costal fold in the male, the antennas have a more distinctly swollen club, the 

 attenuated end beyond it being more slender by contrast. The male genitalia differ in 

 many respects, as a reference to the figures will show. 



P. idas has a very wide range in Central and South America, and is the only member 

 of the <?enus found there ; but two or three modified allied forms occur in the West- 

 Indian Islands.
