Structure: Colour illustration of female and male scale cover by Green (1896e). Female scale semicircular, 1.25-1.75 in diameter; flattish or slightly convex; colour light reddish-brown, minutely mottled with paler specks; first exuvia approximately central; either exposed or bearing the horn-shaped processes of the young scale; the latter is the normal condition, but the exuvia being slightly prominent and the processes very brittle, these appendages are frequently rubbed away; the exuvia itself is divided up into three (a median and two laterals) series of distinct plates; second exuvia very large and broad, anterior margin straight, posterior extremity pointed, its dorsal surface concealed by a horny secretion extending slightly beyond its margin; the scale is closed beneath by the ventral part of the second exuvia; if this ventral scale be carefully dissected off, the adult female will be seen lying within the hollow of the second exuvia; size of second exuvia about 1 by 1.25 mm. Male scale oblong, 1 by 0.75 mm; externally very similar in appearance to that of female, but rather smaller and darker in colour; the single exuvia placed transversely across the scale, near the middle, and usually bearing the larval horn-shaped processes; colour reddish brown; a broad groove below for the reception of the pupa (Green, 1896e).
