Post-reproductive female. King (1913a) described the post-reproductive female as Light brown. 6 mm long, 6 mm broad and 5 mm high; surface shiny. Under normal conditions practically globular, of two distinct forms, one with a deep broad longitudinal constriction, with sides bulging, and four transverse bands of a light cream color. The constriction is not pallid, but of the same color as that of the scale, light brown. The entire surface is peppered with minute black specks ... there are also several large black dots. . . . The other form is of the same color and markings, but distinctly gibbous.
