Remarks

• Systematics: Slide-mounted adult female with: enlarged setae elongate, thin, sides concave, apices acute, setae all approximately same size, abundant over surface; hind coxae with translucent pores (Kuwana, 1917b).
• Structure: Adult female is enclosed in the grayish white, cottony sac. Female body is elliptical, dark purplish red. Eggs are elliptical and flesh colored (Kuwana, 1917b).
• Biology: It is assumed that the species overwinters as an egg which hatches once a year. First instars attack plants in late July, then reach the sac formation stage in the middle of October, laying eggs in the same season (Kuwana, 1917b).
• Economic Importance: The damage caused by the scale can be heavy, resulting in death (Kuwana, 1917b).
• General Remarks: Most detailed description and illustration by Kuwana (1917b).
