The paper presents faunistic data concerning new localities of 20 Carabidae species, which have been rarely reported so far from the Masurian Lake District. One of these species, Calathus mollis (MARSHAM, 1802) has been reported from this region for the first time. Carabids were collected in an agricultural landscape at two types of field complexes: small fields cultivated in a rather traditional way as well as intensively managed large area fields. The presented data complete and update the knowledge on distribution of Carabidae in the Masurian Lake District.
