Dr. Henson (1999) notes that this species is "highly variable in coloration across its range but in this area it is straw colored with two dark stripes on its back and a dark triangle on the head". In a "Field Guide to the Spiders and Scorpions of Texas", J. Jackman (c 1999) indicates that the sting causes local pain and swelling. A word of caution here - different people respond differently to venom injected into their systems and one should always watch out for allergic / severe reactions that require immediate medical attention. With any bite or sting secondary infection is always possible.
