THE COCCIDAE OF SOUTH AFRICA. 29^ 



" $. Denuded of wax 5|-7 mm. long, 4 broad, 2J-3 high, very dark, with a dorsal 

 hump but no lateral humps ; anal horn a mere mammiform prominence. Boiled 

 ill caustic soda the denuded females give a purple colour, which on dilution with 

 water appears pink, and soon forms a flocculent pink precipitate. On adding 

 nitric acid a flocculent white precipitate appears, but the pink precipitate is not 

 altered. Skin after boiling remains yellowish brown, chitinous, with scattered 

 minute gland -dots. Stigmatic areas with numerous crowded gland-spots, and 

 many short and rather thick simple spines, but no capitate spines. Legs dark 

 brown, the parts measuring thus in /^ : Coxa, 120 ; femur mth trochanter, 180 ; 

 tibia, 128 ; tarsus with claw^, 96 to 114. Tarsal digitules 60//, slender, with a small 

 knob. Claw digitules \\'ith very large round knobs, extending about Id^u beyond 

 tip of claw. Antennae apparently only 6-segmented, but the segmentation towards, 

 the end very obscure. The segments measure in ju : (1) 45 ; (2) 60-69 ; (3) 66-78 ; 

 (4) 51 ; (5) 69 ; (6) 72. Segment 5 has a deep notch which makes it look as if 

 divided into two. 



" Young larvae under female about 430// long and 230 broad, tinged with a warm 

 reddish colour. Male scales small, elongate, and glassy." 



In the description of C. africanum var. cristatus Green states that specimens from 

 Natal differ from africanum (i.e., mimosae) only in the presence of a small dorsal crest 

 corresponding to the position of the central scar. They were, however, larger, 

 being 12 mm. in diameter. This would seem to indicate, moreover, that the antennae 

 may be 6, 7, or 8-jointed. 



Habitat : On Acacia, Natal.

Ceroplastes egbarum suhsi^. Julleri, T. & W. Ckll., TheEntom. xxxv, p. 113, 1902. 



Adult $, with waxy covering about 14 mm. long, 12*5 mm. wide and 7 mm. high. 

 Waxy covering regularly domed with a slight depression in centre. Margins widely 

 crenulate, with usually two conical deflected waxy masses which clasp the stem. 

 Stigmatic cleft waxy appendages conspicuous, snow-white, long and slender. 

 There are two of these on each side, usually 3 to 4*5 mm. long, about 1 mm. thick 

 at attachment to waxy covering, but gradually tapering to their extremities. They 

 usually he closely pressed to the stem of the host plant. The colour of the waxy 

 covering is whitish to coral, pink, with distinct bro^Ti patches on the intermediate 

 area and hghter zones around the dome. 



Female, denuded of wax, 7 mm. long, 5*5 mm. broad and 4 mm. high. Colour 

 coral pink, more yellowish than the darker coloured wax. The extreme frontal 

 margin, the stigmatic clefts and the caudal projection are dark castaneous and 

 shiny. In older specimens, after oviposition, the integument becomes brown. 



The venter is flat or concave with the median zone sunken and segmented. The 

 4 white stigmatic bands extend inwards to this sunken area. The lateral margins 

 are shghtly excavate, the upper edge of the excavation being formed by seven 

 depressed conical projections from the intermediate area. The anterior of these 

 extends forward until nearly level with the front edge of the rounded anterior lobe.
