Anal plates ± semicircular, about 160// long and 85/^ broad. The derm is thin 

 and transparent, with numerous small, scattered, simple glands, from some of which 

 short, tubular projections arise. Stigmatic clefts with large numbers of very 

 small, roundly conical, thimble-shaped spines. 



The distinct, long, opaque white lines, the reddish colour, soft wax, etc., suggest 

 quadrilineatus of Newstead, but this latter species has 6-jointed antennae and is 

 obviously quite distinct by other characters of the test. 



Habitat : On stems of Combretum sp., De Wildt, Pretoria District ; collected by 

 Claude Fuller, July 1918. 



Collection No. : 317.

" Female test. White, creamy white or dirty white ; exceedingly soft and con- 

 taining an excess of moisture. Form irregular, with large but ill-defined gibbose 

 protuberances ; sides usually with two narrow opaque Hues of secretion from 

 the stigmatic clefts. No trace of lateral plates. Length, 4-8 mm. 



" Female, adult. More or less hemispherical, with the sides often shghtly com- 

 pressed ; caudal process long ; integument castaneous and highly chitinised, 

 smooth and shining, and without fovea or lateral tubercles. Antennae of six 

 segments, the 3rd being as long as the 4th, 5th, and 6th together ; the last three 

 segments with stifi and bluntly pointed, spinose hairs. Legs small ; hind femora 

 very short and often distinctly incrassate ; hind tarsi equal in length to the tibiae, 

 or sometimes slightly longer. Claw very short ; lower digitules very long and stout ; 

 upper digitules normal. Stigmatic clefts well defined, but relatively small ; stig- 

 matic spines very small and pointed, bases not constricted ; basal attachment 

 (disc) very large. Caudal process (after maceration) transparent and somewhat 

 flexible ; sides with an irregular double row of short spinose hairs, and in addition 

 to these there are two pairs of longer hairs (one pair of which is twice the length 

 of the others) shghtly ventral to the row of short ones and towards the distal 

 extremity. Anal lobes short and highly chitinised. Dorsal pores very small, 

 rather widely separated. Ventral integument opposite the caudal process, with 

 rather extensive groups of circular pores, many of which, in well cleared specimens, 

 are hnked together with lines of dark chitin. Length 4-7 mm." (Newstead.) 



Habitat : On custard apple and avocado, Nelspruit, Transvaal ; collected by

Professor Cockerell's description is as follows : — 



" Waxy female scales often crowded on the twigs, two or more coalescing ; 

 about 11 mm. long, 10 broad, and 6 high, the wax extremely thick, not at all divided 

 into plates, snow-white, here and there with a suffused pinkish stain.
