HELICONIDjE. 



This o-enus ranges from the southern parts of Mexico to the South of Brazil. The species are not numerous, and 

 appear to be rather local. Many of them arc subject to variation in the colour of the posterior wings, and these 

 variations, in some species, seem to depend on locality. 



MECHANITIS. 



Section I. Costal nervure, in the males reaching nearly to the 

 apex of the wing, separating front the subcostal at the, point at 

 which the precostal is thrown off: in the females, united to the 

 subcostal as fur as the middle of its course, then diverging, 

 terminating about the middle of the costa.

Section II. Costal and subcostal nervures separate in both 

 sexes from the point where the precostal is thrown off; the 

 former in the males extending nearly to the outer angle, in the 

 females terminating about the middle of the costa.
