An equally wide-ranging species with E. proteus, in company with which it is found 

 from Northern Mexico to the Argentine Republic, though in the West-Indian islands 

 it is represented by F. Santiago, a slightly different species. Its vertical range in the 

 tropics extends from the sea-level to about 5000 feet. 



The male genitalia resemble those of F. proteus, but there is a spine overhanging the 

 dorsal fissure. (See Tab. LXXV. fig. 7.)

Mr. Butler described this species from specimens from Costa Rica 1 , and we have now 

 traced it southwards into the State of Panama, and northwards through Guatemala 

 to Northern Mexico ; its range in altitude extending from the sea-level to a height of 

 4000 feet. Its relationship is clearly with F. catillus, from which it differs chiefly in 

 the shape of the white mark on the secondaries beneath, an obvious feature replaced 

 in the allied species by an indistinct dusky patch extending to the costa of the wing. 



The male genitalia have a comparatively short tegumen cleft vertically at the end,
