Neck Texas Parks and H'itdlife Department, 4200 Smith School Road, Austin, Texas 78744 Abstract: An annotated species list of the longhorned wood-boring beetles (Coleoptera: Cerambycidae) is presented for southern Texas. The area surveyed roughly corresponds to the Texas portions of the Matamoran and Nuecian districts of the Tamaulipan Biotic Province, including all of the lower Rio Grande valley. Data given for the 178 species include original author citation, range, adult activity period, confirmed larval hosts, and anecdotal collecting and locality information. We propose no taxonomic changes, and nomenclature corresponds to the most recent literature. The species list is ordered according to the monographic revision of the family Cerambycidae (Linsley 1962a, A, 1963a, 1964; Linsley and Chemsak 1976, 1985), excepting that portion of the subfamily Lamiinae not yet treated by those authors, which is ordered according to the checklist of the Cerambycidae (Chemsak and Linsley 1982). Brief accounts of the biological, ecological, and historical aspects of the fauna are discussed. Prior literature on southern Texas Cerambycidae is summarized and collated. Species reared from selected native plants are listed by host, with an updated account of species known to infest Citrus in southern Texas. The origins and phyletic relationships of the fauna are briefly discussed, with a summary of some of the taxonomic limitations complicating faunal analyses of Neotropical Cerambycidae. Literature cited includes all original species descriptions. Introduction Adult Cerambycidae are characteristically elongate, subcylindrical beetles with long anten-nae, fully developed hind wings (numerous species, however, are flightless), and five-segmented tarsi with the fourth segment greatly reduced in size. Variation within the family is extreme; North American genera range in av-erage length from 3 mm (Cyriimis) to over 70 mm (Dewbrachiis) and vary in appearance from obscure, drab ground-dwelling forms to brightly colored, contrastingly patterned insect jewels, ca-pable of swift flight. They are equally diverse
