TJie Coccidae of South Africa.

3. Ehizoecus africanus sp. n. 
(Plate XYII., Figs. 10-lOe). 
The material on which this species is founded consists of 15 $ insects 
which were collected on the roots of flowering plants in Mr. Ayres' 
nursery at Capetown in February, 1906. The specimens were kept in 
alcohol in the Cape Collection. 
As I have never seen the insect alive, and no notes were made at the 
time of collection, it is impossible to give details of secretion, etc. 
The spirit specimens were of a purplish-brown colour, but turned 
purple in boiling KOH. In size they range from 2 mm. to 3"8 mm. ; are 
elongate and narrow, with parallel sides; the two extremities are rounded, 
of about equal width.

^^^^^ — 
R. at'ri canus . 
In mounted specimens the most striking characters are the extreme 
length of the body posterior to the legs ; the prominent anal lobes 
(Fig. 10) with the two or more long setae and several shorter hairs ; 
the elongate mentum ; the geniculated antennae, which are short and 
stout (Fig. 10^^) ; the absence of eyes ; and the 3-grouped glands 
(Kg. 106). 
The antennae are 5-segmented, joint 5 being long, and bearing 4 stout, 
falciform spines in addition to the normal hairs (Fig. lOd). Joint 3 is 
much longer than 2, usually twice the length. 
The measurements of the antennal segments give the following range : 
— (1) 62-68; (2) 15-22; (3) 35-12; (4) 25-32; (5) 98-106.
