Genus Ceroplastodes, Okll. 

 Female scale convex, but not cone-shaped ; not divided into two halves, nor into 

 distinct plates, but rough or beset with protuberances. $ with antennae 7- or 

 8-jointed. 



244. Ceroplastodes bituberculatus, sp.n. (Plate iv, fig. 251). 



Test of adult 5 about 4 '5 mm. long and 3 mm. broad and high, white, with two 

 prominent humps, one at each end of the median ridge ; margin with a distinct 

 white fringe. The test indicates the anal cleft and has a small prominence over the 

 anal lobes. 



, Male scale dull white, with the median area denser, about I'S mm. long, divided 

 into plates in the normal manner. 



Adulfc 5 with the waxy covering removed, dark brown, of similar shape to the test. 

 Integument, when mounted, clear, hyaUne, without glands or hairs. Margin with 

 a single, close-set row of tubular spines somewhat of the Inglisia type but more linear 

 and truncate. Stigma fcic clefts obsolete but indicated in the marginal series of spines 

 by fche addition of three stigmatic spines ; laterals slender, a little longer than the 

 marginal spines ; median stout; two and a quarter times as long as laterals (116 jii). 



Lsgs and antennae long, well developed. Antennae 8-jointed ; range in ju : 

 (1) 27-34, (2) 20-34, (3) 63-68, (4) 31-34, (5) 37-48, (6) 17-20, (7) 17-20, (8) 34-41 

 (from 5 antennae). 



Leg I : coxa 78 ; femur -f trochanter 176 ; tibia 120 ; tarsus 90 ; claw 24/(. 

 Tarsal digitules very long, slender, clubbed ; claw-digitules comparatively slender. 



Anal plates about 145// long, apex with 4 very stout blunt spurs. 



Habitat : On stems of native shrub, Somerset West, C.P. ; collected by T. F. 

 Dreyer, November 1906. Also at Stellenbosch (Fuller).

Genus Idiosaissetia, no v. 



Adult $ secreting a thin brittle covering of waxy material not divided into plates 

 or two halves, and without air cells. Legs and antennae present but rudimentary. 

 Anal cleft not median but to one side. 



Type, /. peringueyi, sp. n. 



245. Idiosaissetia peringueyi, sp. n. 



Adult $ about 2'6 mm. long and 1*3 mm. broad, elongate, very convex, with 

 almost perpendicular sides and sloping abruptly in front and behind. 



Female raised on a hollow waxy sheath which extends over the sides of the body, 

 leaving the dorsum naked. The material is now ten years old and appears as though 

 the waxy covering had once extended over the dorsum, but had become detached 

 from it. If this were covered the insect would look like an Inglisia, except that 

 the waxy covering is thin, pale buf?-coloured and solid, i.e., without air-tubes. 



Female, denuded of wax, densely chitinised, brown, shiny. 



When cleared and mounted the integument of the dorsum is moderately dense, 

 with numerous ± circular clear spaces as in Saissetia bitt. of greatly varying size. 

 The venter is thin and clear. The antennae are rudimentary, usually with about
