We seem to have lost your original letter concerning this bug. It also had us stumped for quite some time. It is a Burrower Bug, Family Cydnidae. According to Borror and Delong: “They are usually found burrowing beneath stones or boards, in sand, or in the mold about the roots of grass tufts; sometimes they are found in ant nests.”
