“ The badge of the society is a shield-shaped piece, enclosing in a sharp point at the top. In the centre of the badge is a field, upon which are displayed five crosses; above this space are the letters “ΦΔΦ,” while a star is in each corner. A badge composed of the monogram is also in use. The fraternity colors are wine color and pearl blue. ”
