These two species, endemic to the largest islands of the West 
Indies, are very similar to one another and evidently closely related. 
They are identical in wing venation and genitalic structure, and 
differ only slightly in size, wing shape and wing pattern. Seitz (1924) 
and Bates (1935) considered them to be subspecies (‘choromorphs’ 
of Bates). However, since there is little variation within each of these 
entities, since the differences between them are very consistent, and 
since they are well-isolated geographically, they are evidently bio¬ 
logically separate species and are so treated here. 
The venational features that distinguish these species are the com¬ 
bination of a single vein crossing from R to Sc, and three veins
