Adult female ovate ; without prominent anal lobes. Body pale purplish 

 grey; limbs and antennae pale etraniineous; venter thinly, dorsum rather 

 thickly and evenly covered with white mealy secretion ; terminal three or four 

 segments of abdomen .with short, stout, waxy tassels. Antenna 8-jointed; 

 8th much the longest, often approximately twice as long as the 2nd — which 

 is the next longest ; other joints subequal,, but varyiug slightly in their relative 

 lengths (see fig. 3, c, d, e) ; in some examples there is an ill-detined clearer band

example (c), all the joints are relatively shorter and broader. I.inibs well 

 developed, moderately stout (fig. 3, b) ; the tarsus rather more than iialf the 

 length of the tibia. Anal ring (fig. 3, a) with 6 stout setae, each of which is 

 approximately three-quarters the length of the caudal setae. Ceriferous tracts 

 inconspicuous, except on the terminal three (or occasionally four) segments, 

 where they are marked by a pair of small but stout spines in a diffuse cluster 

 of small circular pores (see fig. 3, a). Derm with numerous minute circular 

 pores and short setae ; the latter being larger and more crowded on the frontal 

 area. Some larger circular pores around the genital orifice.
