etween the sexes during the respiration ex~eriments. One might have expected a higher respiratory rate developed in species living in cold habitats close to glaciers (especially N. nivalis) than in species active mainly on warm and sunny days (Z. exulans). However, no good correlation seems to exist between the respiratory rate and the type of habitat preferred by different species. Experiments on the temperature preference of beetles. amonE " them N. nivalis and N. gyllenhali, living on the border of glaciers and snowfields, seemed to reveal a eurytherm preference (Krogerus 1960, 0stbye 1963). As the optima of their preferred temperature ranges were around 5' to 20°C, they could be classified as 'cold-loving eurytherm' species. Scholander et al. (1953) found that terrestrial insects from arctic and tropical areas revealed little or no difference in oxygen consumption at the same temperatures. Only in the range of 10-20°C, the arctic species showed a somewhat higher respiration. Among aquatic organisms, however, arctic species showed a clear metabolic adaption to lower temperatures. ACKNOWLEDGEMENTS We wish to express our sincere gratitude to the late Mrs. Jadwiga Hagen for conscientiously performing most of the laboratory work, Mr. Dag Svalastog and Mr. Johan Schmidt for their laboratory work, Cand. real. Arne Hagen and Cand. real Hans-Jergen Skar for valuable advice, master mechanic Odvar Iversen for the construction of respirometers, and Mrs. Margaret Espeland for improving the English.

A new species of Collembola (Isotomidae) from Western Norway. <strong>Norsk</strong> ent. Tidsskr. 21, 127-130. The new species was collected under rotten bark on dead trees in an oceanic BetulalPinus wood near Bergen. It is related to A. septentrionalis Palissa, 1966, but is recogni~ed by 1 + 1 ventral setae of Th. 11, claws with a distinct inner tooth, smaller PAO, and different dorsal chaetotaxy and cuticula structure. Some rernarks on the ecology and distribution of A. septentrionalis and A. laricis Nic. are made. A. Fjellberg, Zoological Mz~seum, Uniuersity of Bergen, N-5014 Bergen-Uniu., Norway.
