There are two long stout spines on tarsus II, and one on tarsus III, 
the other being replaced by a spine-like hair. Tarsal digitules are 
apparently absent. 
The anal lobes are furnished with several (2 to 5) long setae and a 
few shorter hairs. The longest setae measure approximately 170 ^ ; the 
shorter ones 95 /x. Those of the anal ring are usually about 105 ^ in 
length. 
The dermis is characterized by {a) two pairs of "eye-shaped cica- 
trices " (Fig. 10a) ; {h) small pores, some of which have longer or shorter 
hairs (Fig. 106) ; (c) large disc-like gland pores, which are chiefly confined 
to the dorsum (Fig. 10c), and {d) grouped glands, with 3 elongate pores 
pressed together, and presenting a propeller-like appearance (Fig. lOh). 
These 3-grouped glands appear to be widely scattered over the body-surface, 
but are probably in two transverse series across each segment, about 10 
such gland-groups in each row. 
This insect reminds one very much of R. terrestris (Newst.), but 
obviously differs in size. The chief microscopic differences are that the 
grouped glands are far more numerous in africanus than in terrestris ; 
the antennae of the latter, as figured by Newstead (Monograph II, 
Plate Ixix., Figs. 5, 5a) show the 3rd joint shorter, or equal in length with 
2, while in africanus joint 3 is always much longer than 2. The stout 
spines which are so striking on the tibia and tarsus of africanus (Fig. lOe) 
are apparently absent in terrestris. 
Teibe PSEUDOCOCCINL 
Gen. NATALENSIA g. n. Type : fulleri sp. n. 
Larva elongate, of the usual Pseudococcus type. Antennae six- 
segmented, terminal joint longest. Anal ring with six hairs. Caudal 
lobes moderately produced ; each with one long seta and several shorter 
hairs and spines. Adult 2 enclosed in a double-walled cyst of felt-like 
substance, the two layers of similar texture, readily separated. Cysts of 
type species subterranean, attached to roots of grass (Fig. 2).
