nearly extends to both these places, and there is no variation amongst it to justify any 

 separation. The only question is whether ff. nivella is sufficiently distinct from 

 ff. macaira, but the much darker secondaries beneath and their dark uninterrupted 

 margin seem sufficient to distinguish them. The male genitalia offer no tangible 

 differences.

Heliopetes laviana appears to have a continuous range from Northern Mexico to 

 Argentina, being abundant in the low-lying lands up to an elevation of about 3000 or 

 4000 feet. It has been described from specimens taken at several points of this wide 

 area. L. pastor was based upon examples from Mexico, Colombia, and Southern Brazil 5, 

 P. leca upon a Venezuelan specimen 6 , whilst Hewitson's type of L. laviana came from 

 Nicaragua *. There can be little doubt that all these names apply to the same species, 

 which must bear Hewitson's oldest title. 



The male genitalia of ff. laviana are similar to those of ff. nivella, ff. macaira, and 

 other members of the genus.
