This list is based mainly upon parasites reared from field collected material while the author was working at the Bedford Entomological Laboratory of the Purdue University Agricultural Experiment Station during the summer of 1931. Special attention was given to Lepidopterous stem-borers and leaf rollers likely to be found near peach orchards. Several other records, obtained from specimens in the collection of the author, have been included. All records without indication of the year are for the 1931 season.
