The Coccidae of South Africa. 
147 
The greatest diameter averages approximately 2*5 mm. Completed 
ovisacs, when full of ova or emerging larvae, usually exhibit a slight 
yellowish tinge from the colour of the eggs or larvae within. 
Ova : Pale creamy-yellow, 290 fx long and 145 ^ broad. 
Larva : Eecently hatched is the same colour as the egg, but measures 
415 in length. The antennae are 6-segmented with 6 about as long 
as 3 + 4 + 5 which are subequal. Eyes prominent, rounded. Anal lobes 
well produced, each bearing the usual seta. 
^ puparium : The ^ puparium is usually found in the bases of the 
leaves which contain the ovisacs, and is often partially or wholly hidden 
by the latter. It is a delicate, elongate, flattened, white sac, about 2 mm. 
long, closed and rounded in front but open behind. The four white caudal 
filaments and the tips of the wings are visible before the ^ emerges. 
Males were emerging when the material was received on December 19, 
1914. 
^ : The living male is reddish in colour, but the colour is obscured by 
a fine white powdery covering, The wings are white and appear " mealy," 
but exhibit the usual beautiful iridescence. There are four dense white 
caudal filaments, the median pair being slightly the longer, about the 
length of head and body without antennae. The other pair arises from 
the margins of the next abdominal segment and projects somewhat out- 
wards as well as backwards, so that the two pairs of filaments are quite 
distinctly separated. When freshly mounted in Canada balsam the body, 
legs, and antennae are amber-yellow in colour ; the eyes are prominent, 
black. 
Length of head + body : 1 mm. 
Length of wing : 1-1 mm. 
Length of antenna : 0*9 mm. 
The antennae are 10-segmented, the segments measuring (as freshly 
mounted in Canada balsam) :— (1) 40 ; (2) 54 ; (3) 153 ; (4) 125 ; (5) 108 ; 
(6) 102 ; (7) 95 ; (8) 81 ; (9) 75 ; (10) 78. 
The segments bear + irregular whorls of hairs, the majority of which 
are about 60 ^ long. 
The posterior abdominal segments are distinctly separated at the 
margins, the lateral margin being produced in broad rounded projections, 
from which the four caudal setae arise. These latter are approximately 
200 ^ long. 
? : The adult ? is pale canary-yellow in colour, about 2 mm. to 
2*5 mm. long. The lateral filaments are very short, but distinct, and 
gradually increase in length posteriorly. The caudal ones, two in number, 
are also short, about twice as long as the next pair, stout at the base and 
tapering towards the tip. 
The waxy secretion on the dorsum is white and powdery, except that
