The setae of the anal lobes are approxicQately 142 long ; those of the 
anal ring are 68 fi in length. 
Habitat : On grass (sp. indet.), Eosebank, CP., November 25, 1914. 
Material studied consists of 14 adult $ ? and young. I have great 
pleasure in associating the name of C. W. Mally, Entomologist of the 
Cape Province, with this species.

23. PSEUDOCOCCUS MIKABILIS Sp. n. 
(Plate XVIII., Fig. 18. Plate XIX., Fig. 23.) 
A large quantity of mealy-bug material was collected on a spiny-leaved 
plant at Ceres, CP., by Chas. P. Lounsbury, in October, 1898. This was 
stored in tins and envelopes, dry, and as no further collection of this 
species has been made, the following description is made entirely from 
dry material. 
The ovisacs are creamy-white or slightly buff-coloured, and are aggre- 
gated on the leaf-cluster bases in conspicuous masses. Externally the 
sacs appear dense and smooth, but when disturbed they are seen to be 
made up of very fine cottony material. 
The adult is apparently viviparous, from the fact that well-developed 
larvae are present in the mounted specimens (dry material). 
When boiled in KOH the dried female turns a bright brown colour, 
and when fully distended is not more than 1*5 mm. long. Stained and 
mounted the adult ? is seen to have 8-jointed antennae ; but it is a very 
remarkable insect in the following particulars. The legs are short ; the 
dermis is very thickly covered with gland-pores, those of the dorsum being 
about twice as large as those of the venter ; many of the ventral pores are 
furnished with bristle-like hairs ; and the circum-anal region is quite 
unusual. The anal lobes are short and somewhat pointed, and bear the 
usual setae, several shorter hairs and two stout spines ; the anal ring is 
unlike that of any other mealy-bug known to me, as it is decidedly pointed 
posteriorly, with the posterior edges somewhat straightened and more 
heavily chitinized. The six bristles are situated on these thickened edges ; 
the anterior rounded arch is free (Fig. IQo). 
The measurements are as follows : — 
Antennal segments (Fig. 18) :— (1) 17-20; (2) 18-22; (3) 8-15; (4) 
9-15 ; (5) 9-15 ; (6) 18-22 ; (7) 18-20 ; (8) 27-35.
