The following index contains both superspecific and trivial names. Super-
generic names are given in capital letters; valid names are shown in roman,
synonyms in italic type.

Two entries are given to denote transfer of a form from one genus to
another genus, the generic name from which transfer occurred appears in
italics:

acuminata (Marl.), Phyllocolpa
acuminata (Marl.), Pontania

The same procedure is used for the entry of transfers from "Unrecognized
Forms", "Uncertain Disposition", "Nomina Dubia" or "Nomina Nuda” to a
genus or subgenus.

To denote transfer of a form from one subgenus to another in the same
genus one entry is given with two page numbers where necessary. The same
procedure is used to denote transfer of a form from a genus or subgenus
to "Unrecognized Forms", "Uncertain Disposition", "Nomina Dubia" or
"Nomina Nuda".
