Arrangement of the Species. — "With the exception of Hecahe, which has a range of 

 distribution throughout our limits, we have arranged the various described species 

 in geographically local-groups, with the view of thus more clearly indicating the 

 representative, or co-ordinate, species occurriug in each of the various areas where 

 the genus is found. 



Species locally restricted. — As a result of careful and critical comparison of 

 nnraerous specimens of the various named species, we find that they are of restricted 

 habitat, and topomorphic representative species, each species also producing the 

 seasonal forms with modified pattern of the markings on the upperside, this pattern, 

 in the different forms of those of the species as occur in its area of habitat, are 

 found to be perceptibly different, on careful examination and comparison with the 

 co-ordinate forms of other areas — each successive or seasonal form producing the 

 distinctive feature or local difference observable. These differences in the shape of
