THE COCCIDAE OF SOUTH AFRICA. — III. 205 



Habitat : This species seems to be common throughout the Union on wild olive, 

 keurboom (Virgilia capensis, Lam.), kaffirboom (En/thrina caffra, Thunb.) and several 

 other native trees. It apparently takes readily to cultivated plants and has been 

 received on apple, hawthorn, kei- apple, lilac, native plant (Celaslrus sp.), olive, pear, 

 poplar, plane, privet, pepper (Schimis molle, Linn.), Robinia sp., rose, peach, plum 

 and walnut.

Chrysomphalus phenax, Ckll., The Entom. xxxiv, p. 225, 1901. 



Scale of adult $ small, about 1 "5 mm. in greatest diameter, convex, capsular, black, 

 but covered with a secretionary layer of yellowish brown material which shows 

 concentric markings. Exuviae nearly always nearer to one side and covered with 

 a whitish or greyish layer. In very young scales there is a faint concentric ring and 

 dot effect. Ventral scale dense, black. 



Adult $ broadly oval, about 1"1 mm. long and - 9 mm. broad, widest just about 

 level of mouth-parts and suddenly shouldered and narrow T ed to the broad flattened 

 pygidial area. Body hyaline, except the mouth-parts and pygidium, which are 

 yellow. Antennal tubercles small, with one long, curved spine and several small 

 processes, conspicuous because of the " corrugated " chitin surrounding them. 

 Parastigmatic glands 0. Pygidium broad (fig. 120), with four pairs of well- developed, 

 crenulate lobes and three lobular projections of the margin beyond them. Plates 

 rudimentary or absent. Paraphyses stout, and very conspicuous (fig. 120). 

 Circumgenital glands 0. 



Remarks : Professor Cockerell's original description is as follows : — 



" $ scale dark grey, resembling an oyster, with the sublateral exuviae shining 

 black. $ no circumgenital glands ; anal orifice small, about 9/t long, oval, about 

 63,m from bases of median lobes ; lobes four, crenulate, shaped as in C. minwsae, 

 but the median lobes are broader, angular instead of sloping on the outer side ; 

 margin beyond the lobes denticulate and finely crenulate ; club-shaped thickenings 

 at inner bases of median lobes, about twice length of lobes ; a pair of thickenings 

 between first and second lobes, as in mimosae ; three thickenings between second 

 and third lobes, the middle one longest ; two at interval between third and fourth 

 lobes, the middle one being absent ; one or two beyond the fourth."

 Natal ; collected by C. Fuller. Nelspruit, Tvl. ; collected by C. P. Lounsbury.

Genus Pseudaonidia, Ckll. 



The scales are similar to those of Aspidiotus, and some of the $ insects have the 



cephalothorax distinctly separated from the abdomen as in the subgenus Selenaspidus. 



On the dorsal side of the abdomen, however, there is an embossed area reminding 



one of that of Ischnaspis. The body colour is usually wine-red when the insect is
