Norwegian stoneflies II 241 seems to be more commonly distributed and present in a wider range of habitats than elsewhere. In Sweden not taken in the southernmost parts (Brinck 1949). Capnia bifrons has its northernmost distribution in Fennoscandia in Norway (Fig. 51). It has been taken in widely separated localities. The species is common and numerous in small streams largely in the western parts of the Oslofjord and Tynset areas. The species is numerous in some streams in Telemark, common in small streams in 0vre Heimdal, where it occurs in the Low-Alpine vegetation belt at heights of about 1200 m. It has also been taken in the Sub-Alpine belt in other parts of East Norway. The northernmost find is to the south of Mosjoen, Nordland. In the south the species is very numerous in some small coastal streams such as on the island of Nottemy, Vestfold. The species is most abundant in streams where the bottom is unstable and composed of small stones and gravel. In Sweden, it has not been taken north of lake Viinern (Brinck 1949). The species has not been recorded from Finland. Capnia pygmaea (Fig. 52) is also found in both southern and northern Norway, but has a distribution which is different fromCapnia atra and Capnia bifrons. It is the only Capniid species in the inner fjord areas of southwestern Norway, and goes further west than Capnia atra. In the east, the species is most common in the Glama valley from Roros in the north to Elverum in the south. Around Tynset, the species occurs in small and large streams and in rivers such as the Glama. In the southern section it is restricted to the River Gliima, where it is very numerous. In northern Norway it has been taken in both large and small streams. Capnia pygmaea seems to prefer stream sections where the bottom is unstable and fine sand occurs between the stones, that is, in places where some silting occurs. In southern Norway the species has not been taken above the coniferous tree line, but in northern Norway it occurs in the Sub-Alpine belt. It has been found as far south as S
