An old reference (57 pages, 2 plates). I have not used it in-depth, but it appears to have useful information and historical value...especially for anyone working with material from Ohio.

Of course, the catalogue and bibliography for nearctic taxa north of Mexico must be out of date here. For that, one should consult the more recent catalog of Burger(1).

Abstract:

This publication is the first attempt to summarize available knowledge of the tabanid fauna of Texas. It is based on a combination of published records, recent collections, rearing of field-collected larvae and pupae, and examination of the collections of numerous universities, museums and private individuals. To date, 109 species of Tabanidae are known to occur in Texas. Twenty-three species are reported from the state for the first time and an additional 36 species thought to possibly occur in the state are discussed.
