These are indeed Cordyla. The smaller one appears to be a male of C. crassicornis (M2 reaching wing margin, M-petiole about four times as long as r-m), the larger one is a female of another species (M2 not reaching wing margin, M-petiole about 2.5 times as long as r-m) but I do not know which one. It looks as if the antennal flagellum has only nine segments but I have no idea which species that might be., then. Perhaps C. fissa? Jostein?
