This lighter area varies in color from a dirty white to yellowish-brown or yellow, and if very carefully examined with a good hand lens will usually be seen to consist of two portions : First an outer belt occupying a little more than half the space and an inner area usually a little more elevated than the outer, and with a tiny knob or nipple in the centre. Sometimes, but by no means always, a little depressed ring or groove can be seen around this nipple. Occasionally a black fungus growth con- ceals this central area, or a thin waxy film may entirely or partly cover it, but if these are gently rubbed off the normal color will be found beneath. (6) Adult male. (See Fig. 30 a) :—Shape irregularly oval or elliptical, about twice as long as broad; length, about half the total diameter of the adult female; width, as implied, about half the length. Adult male scales are therefore very much smaller than the adult females, not being more than 1-5 the size. The general color varies from a light gray or grayish-brown to black. N'ear one end is a circular area, in the centre of which is to be seen a little knob or nipple which often, but not.
