The Coccidae of South Africa. 
87 
Adult $ : Purplish-black in colour, about 4 mm. long, distinctly semi- 
pyriform, being flattened ventrally and broadly rounded behind while the 
anterior end is narrowed. There is no secretionary covering, but the 
walls of the sac are closely adherent to the body of the insect. On 
placing into boiling KOH a dense cochineal tint is liberated and the 
insect appears sooty-black. The liquid is stained very deeply with a dark 
dusky purple (Eidgway). When cleared, stained, and mounted the insect 
is about 4*5 mm. long and 4 mm. broad. 
The antennae are 3-segmented, joint 2 being longest (44 /x long on the 
inner margin). Joint 3 is irregularly conical, 34 ^ long, and has 8 to 10 
hairs at its apex (Fig. 8). 
The mouth-parts are normal ; legs absent ; and anal ring with 
6 bristles. The circum-anal region is closely pitted w^ith gland-pores 
of two sizes. The larger ones are about 7 in diameter ; the small 
ones only about 2 /x. The latter are supplied with short, parallel-sided, 
subcuticular tubes. There are a number of scattered hairs around the 
anal groove, some of which may attain 130 ^ in length. The setae of the 
anal ring are about 120 /x long. The dermis of the remainder of the body 
is clear except for scattered, small pores, some of which have bristle-like 
hairs. The spiracle-tubes broaden suddenly inwardly, and present a 
reticulated appearance. 
Habitat : On grass, Pietermaritzburg, Natal.

2. Antonina transvaalensis, sp. n. 
(Plate XVI., Figs. 1-la. Plate XVII., Figs. 9-9c.) 
Adult 2 2 in closely felted sacs attached to the bases of stems of 
grasses. 
Ovisacs oval, spherical, or flattened according to the position on the 
food-plant. When attached to the outer surfaces of grasses the ovisacs 
are often clustered and rounded (Fig. 1), when between leaf-sheaths cir- 
cular, and disc-like (Fig. la). The ovisac is usually complete, white, 
densely felted, and brittle. 
In size the ovisacs measure about 2-8 mm. in diameter. There is a 
distinct circular opening in the end of each, through which the white 
waxy caudal filaments of the $ project. Usually there are two such 
filaments almost as long as the enclosed $ , but in a few cases (as in 
Fig. la) there are a number which appear to have been broken olf or 
shed, and others produced. The ? shown in Fig. la was kept in a tube.
