At first they look like thick-ringed pores, owing to the transparency of the 
derm at that point, where it is quite free from gland pores and hairs.

(Plate XVI., Fig. 7. Plate XIX., Fig. 31.) 
Ovisac : The ovisacs are found singly in crevices in the rough bark of 
the old limbs of thorn-trees (Acacia caffra). They are closely felted, 
smooth, and in the majority of cases have the shape and approximate 
size of an adult insect (Fig. 7), being about 3 mm. long and so smoothly 
felted on the exterior as to look like a piece of white kid. In a few 
instances there is a slight indication of a fine silky ovisac protruding 
below this kid-like sac, but such cases are exceptional. At first the adult 
entirely fills the sac, but, as eggs are laid, the body shrinks until the sac 
appears to be filled with ova, amongst which the shrunken body of the $ 
is found. 
Ova : Elongate, oval, pale brown in colour, 0-3 mm. long ; shell with 
numerous longitudinal wrinkles. 
Larva : Pale translucent brown, 0*3 mm. long and 0-15 mm. broad, 
appearing truncate anteriorly. Antenna as long as the width of the 
body, of 6 segments, measuring : (1) 20 ; (2) 23 ; (3) 22 ; (4) 20 ; (5) 20 ; 
(6) 47 ^. 
The caudal lobes are extremely conspicuous, with almost parallel 
sides, and are rounded apically. Eyes large, prominent, with transparent 
** lens." 
Adult $ : 2*5 mm. long, translucent brown in colour ; legs and 
antennae of the same colour. No waxy secretion and no filaments 
except two extremely short caudal ones which appear as two white 
specks. The insect moves very slowly. In boiling NaOH the brown 
colour deepens slightly, but no purplish colour is produced. 
Cleared and mounted the insect is characterized by its long legs and 
antennae and the prominent caudal lobes. The eyes are conspicuous, 
owing to the unusual manner in which they retain the stain. The dermis 
is quite free from the usual hairs except betw^een the antennae, but has 
scattered, single gland-pores, from the centres of which small, acute 
spines project. The usual stout spines of the anal lobes are replaced 
by much more slender ones. In addition to the gland-pores with the 
short spines are a number of slightly larger openings which have distinct 
subcutaneous tubes. In the circum-anal region a number of the spines 
are longer than those of the remainder of the body, but they are always 
acute and spine-like, never linear and hair-like (Fig. 31).
