In the paper records for 37 species of Elateridae, 2 species of Throscidae and 2 species of Eucnemidae from Puszcza Borecka are given. Nine of them are for the first time recorded from the north-eastern part of Poland. Puszcza Borecka is the first lowland locality of Liotrichus affinis (PAYK.), which was known in Poland only from mountains. The presence of many rare species, like Denticollis rubens PILL. et MITT. and Xyloecus corticalis (PAYK.), provides an evidence of primary character of forest associations of Puszcza Borecka.
