A result of the survey of sawfly fauna of the garden of the Institute for Nature Study, Tokyo, made in 1999-2000 is presented. Twenty-seven species of sawflies and woodwasps obtained are listed with collection data, distributional range and knovvn host-plants for each species. They are one species of Xiphydriidae, one species of Argidae, and 25 species of Tenthredinidae. Three species of the Tenthredinidae have been determined only to genera. In addition to these, two tenthredinid species were found but their generic position has not been clarified, and 65 specimens of the tenthredinid genus Pachyprotasis were collected but not determined to species. Thirty-two species of sawflies and woodwasps previously recorded from the Institute for Nature Study but not found during the present survey are listed separately. Of the 41 species of sawflies and woodwasps found in the survey made nearly 50 years ago, 31 species were not re-discovered in the present survey. This apparently large difference in species composition between the results of the two surveys in this same area may possibly reflect the large change in natural environments within and around the garden of the Institute for Nature Study in the last 50 years.
