Excerpt: During July and August, 1954 the late Robert R. Dreisbach of Midland, Michigan, devoted several weeks to the collection of insects in Texas and Mexico. Dreisbach was an extremely active and indefatigable person. His collecting efforts were not limited to the accumulation of materials of immediate interest to him, and he assembled large numbers of many species of insects. He maintained a general collection and, from time to time, sent portions of it to various specialists for determination. Numerous new species have been described from this material. In identifying the Orthoptera, I noted several discrepancies in the date-locality data accompanying the specimens. Fortunately. I was able to work out and clarify a number of these inaccuracies with Dreisbach before his death in 1964.
