The Coccidae of South Africa. 
91 
$ of type species broadly elliptical, flat beneath, convex above ; 
antennae and legs present. Anterior and posterior segments in form of 
rectangular plates, anterior one with median rounded projection. Mouth- 
parts well developed but small. Anal ring large, with six hairs. Caudal 
lobes not produced, but represented by caudal setae. 
This genus most nearly approaches Cryptoripersia CklL, but from the 
formation of the cysts, and the characters of the adult ? , it is certainly 
quite distinct. 
4. Natalensia fulleri sp. n. 
(Plate XVI., Fig. 2. Plate XVII., Figs. 11-llfZ.) 
Adult 2 entirely enclosed in a double-walled cyst. 
Cysts (Fig. 2) : Outer cyst may attain 9 mm. long by 5 mm. broad, 
dark-coloured owing to adherent soil ; brittle when dry. As only dry 
material has been observed by the writer the following description of 
colour, etc., may have to be modified later when fresh specimens are 
obtained. 
Texture — after boiling in KOH for 30 minutes — tough, felt-like, nearly 
1 mm. in thickness, dirty brown in colour. Fragments pressed on slide 
below coverglass in alcohol give one the impression of the texture being 
waxy, not definitely fibrous. 
Inner cyst pale buff-coloured. This has the appearance of being more 
loosely constructed. The outer shape and size are those of the interior of 
the outer cyst, from which it separates readily. Larvae were found inter- 
mingled with the inner layers of this cyst-like ovisac. 
Larva in boiling KOH, from dry material, dark brown, elongate, 
0*6 mm. long and 0*25 mm. broad ; legs long ; antennae normal, of 6 
segments, of which 6 is much longer than any of the others. Two is 
next, being about one-half the length of 6. Others subequal and shorter. 
Caudal extremity as illustrated (Fig. 116). 
3" : Not observed. 
Adult $ (from dry material), after boiling in KOH dark brown in 
colour, broadly eUiptical, 4 mm. long and 4*5 mm. broad, convex above 
and flat beneath. Segmentation very distinct. The anterior and posterior 
segments are rectangular and plate-like. In front the anterior segment is 
produced into a rounded cone, giving the insect the appearance of possess- 
ing a short rounded snout. The antennae project from below the sides of 
the snout as shown in the sketch (Fig. 11), which was kindly made with 
camera lucida by Mr. Claude Fuller. 
Antennae of 6 segments, measurements in ^ : — (1) 34 ; (2) 34 ; (3) 27 ; 
(4) 30 ; (5) 34 ; (6) 68.
