Remarks

• Systematics: Xerophilaspis prosopidis is distinguished from all other North American species by the curiously shaped body of the adult female, with the produced and sclerotized cephalic margin; the reduced pygidium with its 2 pairs of rounded lobes and its lack of perivulvar pores (Ferris, 1937).
• Structure: Female scale minute, shiny black, slightly convex, from circular to very broad pyriform. Exuviae remarkably large for the size of the scale. Male scale oval, larger than that of female, white, with yellowish exuviae towards one end. Males scales are not ridged. Adult female extremely small, transparent after boiling in soda. Lobes small, two pairs, median rounded, nearly as far apart as the diameter of one. 2nd lobes also rounded, but broader and lower than median, nearly as far from them as the diameter of one (Cockerell, 1895z).
• General Remarks: Best description and illustration by Ferris (1919a).
