This is one of a series of papers on the insect life of the Big Bend Region of Trans-Pecos, Texas, in which the author plans to present a fairly complete picture of the insect and animal life of that little known region. The area is composed of Presidio and Jeff Davis Counties, the former mainly Lower Sonoran in its faunal affinities, the latter principally Upper Sonoran and partly Transitional. Each county has its own mountain system; Presidio County the Chinati Mountains and Jeff Davis County the Davis Range. The Chinatis are desert mountains; the Davis are forested with oaks and pines.
