THE COCCIDAE OF SOUTH AFRICA. — III. 207 



There is a marginal series of long (57/.<) hairs at wide intervals, and a number of similar 

 hairs scattered over both surfaces of the body. Parastigmatic glands present, 6-8 

 at the anterior spiracles. The pygidium (fig. 123) is broadly pointed and the pygidial 

 area rather more highly chitinised than the remainder of the body. There are four 

 pairs of lobes ; L 1; L 2 and L :J strongly notched on their outer margins, L 4 rudimentary. 

 The embossed area is large, coarsely reticulate. There are apparently no plates, 

 and the paraphyses are chiefly represented by three pairs of thickened patches, which 

 represent the clubs of the elongate thickenings that become conspicuous when the 

 process of chitinisation has proceeded further. Spines long, as illustrated (fig. 123).

Habitat: On trunk of large native tree (sp. indet., but probably baobab), Busi 

 {near Beira) ; collected by C. Fuller. 



Collection No. : 319. 



105. Pseudaonidia clavigera, Ckll. (Plate xii, fig. 125). 



Pseudaonidia clavigera, Ckll., The Entom., xxxiv, p. 226, 1901 ; Maria tt, Proc. 

 Ent. Soc. Wash., ix, p. 139, 1908. 



Scale of adult $ broad oval to circular, about 2 '5 mm. in longest diameter, 

 completely covered by the outer layers of the host-plant stem, but with the brownish 

 or resinous coloured exuviae faintly exposed. Seen from below when the scale is 

 raised, it is flatly convex, biownish in colour. 



Adult $, when mounted, large, about 2 mm. long, broadly rounded in front and 

 pointed behind. The cephalothorax extends backwards one- third of the entire length 

 and is deeply divided from the abdomen. The mouth-parts are comparatively 

 very narrow, only occupying one-tenth of the width of the body. The abdominal 

 segments are well defined, the two anterior ones united into a broad band, the third 

 free segment narrow with the margins rounded. The whole body-wall is dense, 

 and the reticulated area is well defined and distinct. The pygidium is pointed, and 

 is made conspicuous by the two pairs of parallel thickenings with clubbed heads 

 which extend from the margin into the pygidial area. Pygidium as illustrated 

 (fig. 125). Circumgenital glands 0. 



Habitat : On camellia, Durban ; collected on several occasions by C. Fuller and 

 A. Kelly. 



Collection No. : 220. 



106. Pseudaonidia laciniae, sp. n. (Plate xii, fig. 128). 



Scale of adult $ circular, about 1"5 mm. diameter, hemispherical, completely 

 covered by the bark of the host-plant, through which the black exuviae show faintly. 

 When raised and seen from below the scale is capsular, like a Chrysomphalus, with 

 a ventral layer of dense black material like the dorsal scale. The inner wall of the 

 scale is shiny black. 



The adult $, when alive, is dark plum-coloured, with the pygidium brown. When 

 mounted it is transparent, with the mouth-parts and reticulated area of the pygidium 

 yellow. Mounted specimens generally contain large numbers of well-developed 

 embryos. The body is about 1"5 mm. long, rounded in front and pointed behind.
