Abstract BzTRANowSI(r, R. Some contributions to the knowledge of the beetle faurra at the lower parl of River Daliilven. 1. - Ent. Tidskr. 96:97-115, 1975. The beetle fauna of the area surrounding the lowest reaches of River Daldlven was first investigated by Thure Palm, who published tho results of his studies in Entomologisk Tidskrift in 1942 and 1955. Since then many coleopterists have been working in this area, highly interesting because of the remainders of primeval forest to be found lhere. In the present paper the author gives atr account of the most remarkable finds that hc and other entomologists, partl-"- through application of nerv collecting methods, made in the arc{r after Palm's papers were publishcd. A Sreat number of species new to the area are reportetl, thirty-six species are for the first time recorded for the province of Upland, one species (Liotlcs Iitura Steph.\ being new to the Swedish faunn. Notes on the biology and ecology of several species are given, especially of those living irr dead trees.
