McGuire, W.W. & M.A. Richard. 1974. An annotated checklist of the butterflies of Bentsen-Rio Grande Valley State park and vicinity. Texas Parks & Wildlife Department, Austin. Mimeograph pp. 1-22.

Introduction (in part)

The species listed here in are primarily a result of the collecting by the authors during the period 1972-1973. Certain important records of the previous several years are also included. Additionally, the checklist incorporates records of a number of other lepidopterists. The primary focus of the checklist, then, is upon recent collecting, rather than being an attempt to list all known records from the Mid-Valley area.
