This publication is the second supplement to the 1992 catalog and udates information from 1995 to the end of 1999. A bibliography including over 1300 references is included. A complete index to all species names, both valid and invalid, of the world fauna Scolytidae and Platypodidae is included.

This publication supplements Wood & Bright's 1992 catalogue of the world's Scolytidae and Platypodidae (bark beetles), updating the taxonomy of these two families to nearly the end of 1995 and including all known literature references to the end of 1994 (plus references to articles missed in the earlier bibliography). References which provide new information on taxonomy, host plants, or biology of a species are also included. The format of the supplement closely follows that of the 1992 catalogue. Each genus & species is listed with its page number from that catalogue; additional information on figures, distribution, hosts, and references to other subject areas are given. The publication also includes lists of host plants, arranged by scientific name, and the beetles attacking them.

This first supplement to the 1992 catalogue of the Scolytidae and Platypodidae (Coleoptera) of the world (Wood and Bright, Great Basin Naturalist Memoir 13) updates the taxonomy, distribution, biology and literature pertaining to these families at the end of 1994. The format of this supplement follows closely that of the 1992 catalogue. Each genus and species is listed with its page number from the 1992 catalogue; additional information on figures, distribution, hosts and references relating to one or more of eight subject areas, as in the 1992 catalogue, are given. The bibliography included with this supplement lists 1420 references, most published between 1990 and 1994, including additional pre-1990 references missed in the 1992 catalogue or the previously published 1987 bibliography. Several 1995 references referring to taxonomy, host plants or general biology are also included. New synonymies and new combinations are proposed.
