Plate XVI, Fig. 4, shows distribution of pores etc., round anal lobes. 
Type: Specimen mounted measures 2.7 mm. long by 1.8 mm. broad. 
Dermis, with numerous scattered pores and numerous short hairs or 
spines, especially along the median zones of the segments. On the dorsal 
surface, towards the anterior end, the hairs are numerous and longer, 
some reaching 72 yu in length. 
Antenne: The segments measured in yu are: ?, 53, 43, 25, 28,.27, 32 
and 80 uw on one side, and 64, 56, 44, 22, 32, 26, 31 and 80 uw on the other. 
The Setze on the anal lobes are 155 w and 158 yu while those of the anal 
ring average about 136 uy. 
Legs: Measurements in up.

Remarks: This species was only found on Wachendorfia 
paniculata Linn. The material was collected by the writer on 
Newlands Flats, about eight miles from Cape Town, on October 
3, 1910. The mealy-bug was found on thirty per cent of the 
plants of this kind pulled up in an area of about two hundred 
yards square, but was not once found above the surface of the 
ground. It was between the leaf-bases, and extended from 
half to one and a half inches down. The ground was composed 
of white sand. Ants were in constant attendance and had in 
some cases raised the sand slightly around the stem of the 
plant. It was this fact that attracted my attention. It was 
noticeable that some half-mile away, where the plant was fairly 
plentiful again, no mealy-bug could be found. It might be 
suggested that the colonies of ants have something to do with 
the distribution as the plants are generally somewhat scattered. 
Pseudococcus muraltiz n. sp. 
Ovisac: Spherical, 2.3 mm. in diameter, white, fibrous. Large clus- 
ters of ovisacs occur sparingly, and are generally overrun by ants. 
Plate XIV, Fig. 1 shows such a cluster three-fourths natural size. 
Ova: Orange yellow in color, oval, averaging 240 uw long by 180 pu 
wide.
