INDEX TO PART II. 
Nore.—This index includes also reference to species figured in Part I (text figures), and all page references are to that part. In order to make 
the figured species easily accessible to one not familiar with the numerous changes in the generic references the entries are arranged alphabetically 
by genera, subgenera, species, and varieties. Roman numerals refer to plates, arabic numerals to the figures on the plates. The index to Part I 
includes the plate and figure reference of each of the type specimens figured in the monograph.
