wings of H. charithonia. The clasper shows a near relation 

 to erato, but there is a peculiar formation below the twisted 

 projection, giving it the appearance of having been pinched 

 (PL XVII). 



Charithoniformes. 

 H. charithonia, Linn. 



A common and well-known species having a very wide 

 range over S. America and even into southern N. America. 

 The clasper is very small for the size of the insect, and 

 though not very characteristic may probably be regarded 

 as distinct (PI. XVII). There is one subspecies, peruviana, 

 Feld., in which the claspers are similar. 



H. nattereri, Feld. 



Of this rare Brazilian (Bahia) species I have had no 

 example to examine. 



H. fruhstorferi, Riff. 



Resembles the above and is thought to be its female. 

 I have not seen an example. 



Clysonimoformks. 



H. clysonimus, Latr. 



The typical and two subspecies are described from 

 Central America, Colombia, and Venezuela. The principal 

 characteristic feature of the clasper, shown on PI. XVII, 

 is the compressed appearance of the end of the dilated 

 portion. 



H. hortense, Gruer. 



From Ecuador, Colombia, Guatemala, and Honduras. 

 The clasper (PI. XVII) has a curious little hook-like 

 projection. 



H. telesiphe, Doubl. 



From Peru and Bolivia. A form with yellow instead 

 of white band on hind-wing (sotericus, Salv.) occurs in 

 Ecuador. The clasper on PL XVI] is simple and not very 

 characteristic. Though somewhat resembling sapho forms, 

 the uncus (not shown) is of a stouter form and slightly 

 toothed. 



We have now considered the apparent relationships of
