THE COCCIDAE OF SOUTH AFRICA. 7 



The marginal spines are comparatively short (37//), truncate, with the extremity 

 slightly forked. They are set at an average distance of about bOju apart. The 

 stigmatic clefts are deeply indented but not recessed ; each with about 8 spines, 

 of which the laterals are comparatively long and stout (60//) ; the middle spine 

 is only a little longer, but stouter. The tarsal digitules are very long and slender ; 

 those of the claw are short and very broad.

198. Lecanium proteae, sp. n. 



Adult 5 about 6 mm. long and 4"5 mm. broad (longest specimen seen reaches^ 

 8 mm. by 6 mm. broad) ; colour, when aUve, asphodel green (Ridgway) with 

 very narrow margin of pale dull green yellow. The dorsum is dull coriaceous, giving 

 the insect the colour and appearance of the leaf, the green body corresponding with 

 the blade and the yellowish margin with the midrib or edge of the leaf. 



The anal plates are small, yellowish in colour, except in old specimens, in which 

 they are tinged with brown. 



In form the insect is uniformly oval, except when situated near the midrib or 

 edge of a leaf, when the form is irregular. Above, the body is moderately convex. 

 Below, the insect is uniform green in colour. In boiling KOH it turns to orange 

 yellow then reddish brown. After treatment the derm is colourless. 



Anal plates about 205// long, outer angles rounded, apices attenuated, with two 

 apical spines, one subapical and one on the disc at about one-third the length from 

 the apex. Anal ring w^th 6 long hairs. On the dorsum, immediately behind the 

 anal opening, are two scattered groups of "rosette" glands, and there is a further 

 transverse series on the segments immediately anterior to the two groups. The 

 integument is otherwise clear, but has scattered hairs of varying lengths. 



Stigmatic clefts shallow, with short, varying, clubbed processes. 



Antennae usually T-jointed with the fourth showing a pseudarticulation ; some- 

 times 8-jointed; 7-jointed form : (1) 27, (2) 37-41, (3) 51-58, (4) 44-48, (5) 20-24, 



(6) 20-24, (7) 41-54/< ; 8-jointed form : (1) 27, (2) 41, (3) 61, (4) 34, (5) 31, (6) 20, 



(7) 20, (8) 51//. 



Leg II : coxa 54 by 65, femur + trochanter 127 by 37, tibia 95, tarsus 17, claw 20/,/. 



Marginal spines very short (17//) at very wide intervals, averaging at least 80// 

 apart, simple, truncate. 



Male scale of the usual type, 2-0 mm. long and r2 mm. broad. Head and body, 

 without genital sheath, 1*6 mm. long. Head and prothorax rufous to nearly black, 

 gUstening ; body reddish, tip of abdomen and spine lighter, yellowish ; legs dark, 

 sUghtly darker than antsnnae. Caudal filaments, two, w^hite, about as long as the 

 head and body without antennae. Wings whitish, 1*6 mm. long, mealy, with a 

 subcostal reddish Hne running three-fourths of length of wing from the base. 

 Antennae 1 mm. long, of ten joints. 



Larva, newly emerged, 0*5 mm. long and 0-25 mm. broad, orange yellow, very active. 



Habitat : On leaves of Protea, Pretoria ; common.
