The paper presents new faunistic data regarding the occurrence of coprophagous scarab beetles in the eastern part of Poland. The list includes 31 species: 7 from the subfamily Scarabaeinae and 27 from the subfamily Aphodiinae. Particularly noteworthy are two species, which are new to Masurian Lake District: Onthophagus joannae and Chilothorax paykulli. The part of the country in question is relatively well-studied, albeit unevenly, in terms of coprophagous scarab beetles distribution.
