The Coccidae of South Africa. 
105 
mounted in Canada balsam, 0-51 mm. long, 0-21 mm. broad. Antenna with 
6 segments, of which 6 is longest, being as long as 3 + 4 + 5. Segment 1 
comparatively long ; 2, 3, 4, 5 subequal. Anal ring with 6 hairs. Caudal 
lobes each with one long setae, which is about twice as long as those of 
the anal ring, and two slender spines. 
Adult $ : The dorsum of the 2 is covered by a rather dense powdery 
secretion, usually white, occasionally yellowish. No lateral filaments 
observed, but in some cases two short caudal ones were present. The 
colour of the insect, as seen at the segments, or in old adults, is shining 
black. In boiling KOH the black colour is retained until the body is 
nearly cleared, when it has a decided green tint, and is exceedingly 
difficult to clear. In this it reminds one of Ps. filavientosus Ckll. The 
hquid is stained but very slightly, having a slight violet tint. 
$ Mounted, varies in size, but is most often about 3 to 3*5 mm. long 
and 1-8 to 2 mm. broad. The derm is clear and bears scattered solitary 
pores and a few scattered hairs in the anterior portions, and some spine- 
like bristles on the posterior segments. The antennae are 7-jointed, the 
segments measuring as follows : — (1) 32-38 ; (2) 30-34 ; (3) 30-34 ; 
(4) 18-23 ; (5) 17 ; (6) 20-27 ; (7) 64-72.
