A study of the magnetic structure of TbMn0.33Ge2 has been made using a neutron diffractometer of better resolution and new results have been obtained. The paramagnetic neutron diffraction data confirmed the CeNiSi2 - type of crystal structure reported earlier for this compound. The magnetic moments are located on terbium. At 1.5 K Tb magnetic moments have two components: a collinear and sine wave modulated one so the magnetic order at this temperature has a complex character. With increasing temperature, the change of the magnetic structure to the new sine wave modulated one is observed near the Neel temperature TN=28 K.
