In the two earlier papers (Jewett, 1958, 1960) dealing with stoneflies from the Northwest Himalaya, I recorded 12 species. Dr. Mani has sent me another lot of material from the same region which includes 9 of the species previously recorded and 3 additional ones, two of which are described and assigned to the genus Amphinemura (Aubert, 1959). The third species appears to be an additional species of Amphinemura. but since it is represented by a single male specimen, I am not describing it at present. Very likely with more extensive collecting ever a longer seasonal period additional species, particularly Nemouridae, will be taken from this fascinating area (Mani, 1962).
