THE COCCIDAE OF SOUTH AFRICA. 13 



Newstead states thafc Lecanium (Saissetia) sylvestrii, Leon., has some similarity 

 to persimile, but the former has 7- jointed antennae and three transverse ridges across 

 the dorsum. 



Habitat : On Combretum, Muckleneuk, Pretoria ; collected in October 1914. 



Collection Nos. : 115 and 124. 



207. Saissetia subpatelliforme, Newst. (Plate i., fig. 237). 



Lecamiim (Saissetia) subpatelliforme, Newst., Bull. Enfc. Res. vii, p. 366, 1917. 



Adult § large, reaching 7 mm. long, 5 mm. broad at the base and 3*5 mm. high, 

 very convex but ± conical, with the margin at the base slightly produced as a 

 rounded ridge. The colour is dark castaneous to almost black, sHghtly shining, 

 and without white flecks. There is no dorsal H, nor prominent ridges of any form 

 (fig. 237). 



Younger forms are Ughter in colour, flat, disc-Hke, with the margins slightly 

 raised and rounded and the median area wrinkled. The anal cleft is apparently 

 obsolete and the anal lobes inconspicuous. 



Antennae 8-jointed ; range in ju : (1) 37-47, (2) 35-51, (3) 75-78, (4) 54-58, (5) 

 41-54, (6) 24-27, (7) 17-20, (8) 51-58. 



Professor Newstead's description, omitting figure references, is as follows : 



" Female, adult. Varying from broadly to narrowly ovate, centre generally 

 highly gibbose ; surface rather roughened or shghtly rugose, often with widely 

 separated patches of secretion, especially at the sides ; dorsum (gibbosity) often 

 shining. Derm cells of the median and sub-median areas small, ovate and widely 

 separated, those near the margin much larger. Marginal spines of two kinds : 

 (1) long and rather stout, dilated and divided on both sides ; (2) similar, but only about 

 half the length of the long ones. Stigmatic clefts practically obsolete ; spines three, 

 the laterals small, stout and pointed ; central one missing in all the preparations. 

 Eyes well defined. Antennae of seven or eight segments (both forms present in 

 one $). Legs well developed ; tarsus almost equal in length to the tibia ; lower 

 digitules stout, upper pair normal. Anal lobes with the base and outer edge of 

 equal length, approximately. Anal ring of eight hairs. Anal cleft varying in length 

 from a little less than a third to one- third the length of the body. Length, 

 3-8-5-2 mm." 



Habitat : On stems of Cedrela toona, Salisbury, Southern Rhodesia ; collected 

 by Rupert Jack, June 1917. Also on stems of Syringa, Salisbury ; collected by 

 Rupert Jack, February, 1909 (119a). 



Collection Nos. : 119 and 119a. 



208. Saissetia oculata, sp. n. 



Adult $ elongate, 8 to 9 mm. long by 4 mm. wide, moderately flat, duU, buff to 

 brown in colour, with the eye-spots and anal plates darker, almost black ; margin 

 more chitin-brown, with a conspicuous fringe. Dorsum with rows (3) of hairs 

 similar to fringe. Eyes distinct, almost circular, about 165// in diameter, with 

 darker central prominence. Integument with faint oval ceUs, widely scattered. 

 In the specimens examined these are most conspicuous around the anal lobes,
