Abstract
Very few papers have been published on the life history of pseudoscorpions. The literature has been summarized by Kätner (1927), J. C. Chamberlin (1931), Beier (1932) and Roewer (1936-1940). The following contributions are based upon observation of two species of pseudoscorpions which were kept in captivity. I should like to give sincere thanks to Dr. J. C. Chamberlin for reading the paper and giving valuable suggestions, to Dr. C. C. Hoff for determining the chernetid pseudoscorpions, to Mrs. Rosalie Rogers Talbert for assistance in maintaining and feeding the pseudoscorpions; and to my wife who has aided in the work.
