A single specimen of Theocolax formiciformis Westwood, 1832 is reported together with new data on Cerocephala cornigera Westwood, 1832 and Cerocephala rufa (Walker, 1833) in Norway. Notes on the mating behaviour of C. cornigera and the purpose of the ornamental growths of the males are discussed. Species in this group parasitize on wood-boring Coleoptera and are hyperparasitoids on other species of Hymenoptera parasitoids. The biology and distribution of each species are briefly discussed.
