Hamb. Wiss. Anst. xxvi, p. 10, 1908. 



Scale of adult $ about 2 mm. in diameter, circular, flat, semi-transparent, pale 

 brown or yellowish brown or dirty smoky brown when old, sometimes with margins 

 very pale, often shiny, with central exuviae golden yellow. 



Puparia of $ smaller, more elongate, brownish, with lighter exuviae. 



$ second stage non-articulate. 



Adult $ viviparous, with the cephalothorax distinctly separated from the abdomen. 

 Body-wall yellow-brown, densely chitinised ; front margin flatly rounded, very 

 finely crenulated, but without tubercles ; posterior lateral angles of cephalothorax 

 each with one spiny process, which is usually longer than its breadth at the base. 

 The integument is finely stippled, and there is a sub-marginal series of small hairs 

 at wide intervals. The antennae are small, with one long curved seta and a stump 

 which may represent a second seta which has broken away. Parastigmatic glands 0. 



Circumgenital glands in two groups : 



6—12 6—12 



The pygidium is rapidly narrowed but rounded, the ends of the four normal lobes 

 being almost level. Lobes and plates as illustrated (fig. 104). 



Habitat : On Carissa grandiflora, Durban ; collected by A. Kelly, 7th June 1908. 

 On variegated ornamental plant (Euryea ?), Pietermaritzburg ; collected by C. Fuller. 



Collection Nos. : 223 and 225. 



92. Aspidiotus (Selenaspidus) pertusus, sp. n. (Plate vii, fig. 103). 



Scale of adult $ may reach 2'6 mm. in diameter, circular, flat, dull rusty brown in 

 colour, with margins slightly paler. Exuviae yellowish or reddish brown. Second 

 exuviae usually somewhat sunken. In old specimens exposed to the sun the scale 

 often becomes + bleached. 



Puparium of $ smaller, more elongate and paler in colour, yellowish brown. 



Body of adult $ narrower than in articulatus, longer than broad (1.5 X 1mm.) with 

 deep articulation. Posterior lateral margin of abdominal region with distinct process. 

 The integument is very highly chitinised, appearing dark brown in mature specimens, 

 but with distinct, transparent, hyaline perforations. These are in three series : 

 (a) a loop of about 10 spaces below the position of the mouth-parts, across the cephalo- 

 thorax ; (b) an interrupted series across the abdominal segments ; (c) the pygidial 

 series, which comprises a band across the base, four posterior to these lying longi- 

 tudinally in two pairs, and a few elongate, narrow ones between these and the margin 

 of the pygidium. Antennal tubercles small, each with two moderately long, curved 

 setae. Dorsal glands and tubular glands numerous. 



Circumgenital glands in 2 groups : 



7—10 7—10 

 usually 8. Occasionally 1-2 glands are separated and might indicate that 4 groups 

 may be present. Pygidial characters as illustrated (fig. 103).
