1. This paper is a result of the survey which has been done in two torrents on Mt. Eboshi, Nagano Prefecture, in the years 1952-53, on the aquatic insect fauna and its productive potentials.<BR>2. The productivity of the River Kakuma is greater than that of the River Kanabara when compared with each other at the same altitude.<BR>3. The difference between two rivers under consideration seems to be caused by the qualitative structure of the rocks which constitute the substrata.<BR>4. The productive potentials measured by dry weights of animals per unit area of the river bottom are graded as 6 : 2 : 2 : 1.5, concerning Trichoptera, Diptera, Tricladida, Ephemeroptera and Plecoptera.
