Magnetic properties of tetragonal compounds DyB2C2 and HoB2C2 are investigated by magnetization, specific heat and neutron diffraction experiments. An antiferroquadrupolar (AFQ) ordering occurs below TQ = 24.7 K with a successive magnetic transition at TN = 15.3 K in DyB2C2. In contrast to DyB2C2, an AFQ transition in HoB2C2 occurs at 4.5 K below an antiferromagnetic transition temperature at 5.9 K.
