This publication contains additions and corrections to "An Annotated List of Generic Names of the Scale Index (Homoptera: Coccidea)" by Harold Morrison and Emily R. Morrison, published October 1966.

This second supplement contains 110 names proposed between January 1, 1964, the cutoff date of the previous lists, and December 31, 1972. In addition, It includes eight generic names from a 1962 article, which was not available to the authors of the previous lists, and two names published in 1973 as replacements for preoccupied 1967 names.

This list of generic names of the Coccoidea, or scale insects, is an outgrowth of a card catalog that has been maintained for many years in the identification unit of the organization currently known as the Entomology Research Division of the U.S. Department of Agriculture. A catalog of names, with associated data, is a prerequisite for taxonomic and other investigations of coccids cared on at the Department of Agriculture, and is equally valuable to other persons undertaking similar studies on this group of insects.
