No record of any published paper relating to them can be found, and it is believed, we suppose, that because Indiana lies next to Illinois, where Dr. Cyrus H. Thomas did much of his work, that most if not all of the species of the family found in this State are included in the two lists of the Orthoptera of Illinois prepared by him.
