Abstract. — A catalog of the eriococcid scale insects of the world is nearly complete and will soon be placed on the World Wide Web. Before this is done, new nomenclatural changes need to be validated in print. Therefore, this publication includes 191 new com-binations, four replacement names, and one new generic synonym. Key Words: Felt scales, Coccoidea, Eriococcidae, catalog, new combinations, replace-ment names We currently are completing a systematic database and manuscript on the Eriococci-dae of the World. It is part of a larger pro-ject called ScaleNet to develop a systematic database of the Coccoidea of the World. ScaleNet is funded by the United States-Israel, Binational Agricultural Research and Development Fund (project No. IS -2423-94) and is being undertaken jointly with Yair B en-Do v, Department of Entomology, Agricultural Research Organization, The Volcani Center, Bet Dagan, Israel. The da-tabase resides in BASIS a user friendly cat-aloging system that resides in FoxPro and was developed by Gary Gibson, Eastern Cereals and Oil Seed Research Centre, Ag-riculture Canada. The database application is Microsoft FoxPro. The purpose of this paper is to publish all new nomenclatural information that has resulted from our cataloging activities. Be-cause we intend to make the database avail-able through the World Wide Web, it is im-portant that all new information be validat-ed through publication before it is made available via the Internet. Within the Eriococcidae, the most con-troversial and variable generic concepts center around the status of Acanthococcus Signoret, Anophococcus Balachowsky, Er-iococcus Targioni Tozzetti, Greenisca Borchsenius, Gregoporia Danzig, Kaweck-ia Koteja and Zak-Ogaza, and Rhizococcus Signoret. Hoy (1963) in his catalog of the Eriococcidae of the World treated Acantho-coccus and Rhizococcus as junior synonyms of Eriococcus, but considered Greenisca to be distinct with Anophococcus as a junior synonym. Williams (1985) adhered to Hoy's system but also synonymized Green-isca and Kaweckia. Other researchers have continued to rec-ognize the various genera as separate valid entities, e.g. Kosztarab and Kozar (1988). The characters used to distinguish these genera usually involve the distribution of the enlarged setae and the presence and dis-tribution of various kinds of dorsal sessile pores. For example, Rhizococcus is char-acterized by having enlarged setae that are restricted to the body margin, in contrast to Acathococcus which has the dorsal enlarged setae scattered over the dorsum. If a careful analysis is made of the species that possess
