THE COCCIDAE OF SOUTH AFRICA. 5 



The antennae are 7 or 8-jointed, most often 7. The following range is obtained 

 from a series of eight measurements : — 7-jointed : (1) 24-34, (2) 54-61, (3) 54-61, 



(4) 68-75, (5) 24-31, (6) 14-24, (7) U-Alju ; 8-jointed : (1) 34, (2) 51, (3) 65, (4) 51, 



(5) 30, (6) 20, (7) 21, (8) 41//. 



Leg I : coxa 68, femm* + trochanter 170, tibia 126, tarsus 75, claw 20//. 

 Tarsal digitules very slender, hardly perceptibly clubbed. Trochanter with an 

 apical spine about 85/« long. 



Scattered over the integument; particularly around the antennae and anal plates, 

 are numerous hairs, the longest of which may reach 80// in length. 



The marginal spines are comparatively long (SOju), slender, sUghtly curved, not 

 truncate. They average approximately 54^a apart. The stigmatic cleft has two 

 short spurs and a median longer one (40//). The anal plates are comparatively 

 short (142/<) and broad (170/i across the outer angles). The anal ring has six long 

 hairs. The derm is apparently clear, without glands. 



Habitat : On Ehretia hottentottica, Burch. ; collected by the writer at Brooklyn, 

 Pretoria, October 1914. 



Collection No. : 117. 



194. Lecanium pumilum, sp. n. 



Adult $ small, about 2 mm. long, and 1*5 mm. broad, moderately convex, dark 

 reddish brown in colour, distinctly red when younger. 



Antennae 7- or 8-jointed, more often 8. The following represents the range 

 obtained from measuring the antennae of five insects : — 7-jointed : (1) 20-24, 

 (2) 34-37, (3) 51-54, (4) 27, (5) 24, (6) 17-20, (7) 41-54// ; 8-jointed : (1) 24-27, 

 (2) 27-44, (3) 48-51, (4) 17-24, (5) 24-34, (6) 17-20, (7) 17-20, (8) 37-44,m. 



Leg I : coxa 51, femur -f trochanter 153, tibia 95, tarsus 61, claw 17//. 



The anal plate is about 150/t long. The anal ring is produced on a deHcate fluted 

 tube ; it bears 8 long bristles and several shorter ones. The margin has the usual 

 series of simple spines about 41/< long. Stigmatic cleft with 3 straight, moderately 

 stout spines ; laterals about 24// long, median about 71//. Immediately within the 

 margin are numerous scattered small simple gland pores, many with short sharp 

 spines. 



Habitat : On the stem of a native shrub, covered by a carton shelter constructed 

 by ants ; collected by C. P. v.d.Merwe at Robertson, C.P., May 1915. 



Collection No. : 125.
