The postmedial line is scalloped, focally excurved around the reniform spot and straight at a strong slant toward the base below the level of the cell. The dark median line is prominent in most specimens. The subterminal line is pale, similar to the filling of the other lines, moderately irregular in course and preceded by a gray shade that is as dark as the median line. The fringe is of the ground color. The orbicular and reniform spots are fain
