199. Lecanium wistariae, sp. n. 



Adult $, mounted specimens about 3*4 mm. long by 2 mm. broad, elongate, 

 tapering to each end. The following description, taken from the Cape Journal, 

 was made from fresh material : — 



" Young appearing August 15th ; females apparently viviparous, since, while 

 bodies are fiUed with eggs, only living young are seen under the scales. 



" Female long oval, highly convex. Ground-colour yellow obscured by 

 reticulations of black ; the black enclosing minute, almost round patches and 

 bounding larger patches of irregular shape and size ; in a few specimens there is 

 an obscure median stripe of yellow, but this is never well defined and generally 

 altogether lacking. A tinge of red or rose is apparent about the whole margin of 

 some specimens and this in a few extends as a flush over the whole dorsum." 



Antennae 8-segmented ; range: (1) 30-34, (2) 36-42, (3) 54-62, (4) 34-44, 

 <5) 48-52, (6) 26-30, (7) 20-24, (8) 34-38//. 



Leg I : coxa 54 by 70, femur + trochanter 170 by 40, tibia 130, tarsus 68, claw 20//. 

 The tarsal digit ules are slender and clubbed. 



Margin with a series of slender spines, 44/< long, not truncate. Stigmatic cleft 

 spines similar but stouter. Anal plate 125// long. 



Habitat : On wistaria, Uitenhage, collected August 1901 ; Cape No. 1286. 

 Thickly clustered on thin twigs of plant ; also said to be on rose and AustraUan 

 myrtle. 



Collection No. : 113. 



200. Lecanium durbanense, sp. n. 



Adult $ about 5 mm. long and 4 mm. wide, broad egg-shaped, with the extremities 

 broadly rounded. The anterior end narrows perceptibly just in front of the middle. 

 Body flat, mahogany-brown, with the margins and a faint median ridge somewhat 

 darker, glossy. 



When mounted, the most striking character under the low power is the chitinisation 

 of the dorsum. In a specimen measuring 5 mm. in length a conspicuous chitinised 

 Une proceeded from the anal lobes along the middle of the dorsum to the level of the 

 mouth-parts. A faint chitinised band was also noticeable around the margin. 



The antennae are 7-or 8-jointed, with the following range in ^u : — 8-jointed series : 

 (1) 27-34, (2) 34^1, (3) 37-51, (4) 34-48, (5) 41-44, (6) 27, (7) 27-31, (8) 44-51 ; 7- 

 jointed series: (1) 27-34, (2) 37, (3) 37-51, (4) 37-41, (5) 41-44, (6) 37-51, 

 (7) 48-51. 



Leg I : coxa 88, femur -f trochanter 187, tibia 119, tarsus 82, claw 20^u. 



Anal plates about 156/^ long, comparatively slender. The marginal zone appears 

 more chitinous than the median area with the exception of the ridge previously 

 mentioned. The chitin of the zone appears stippled ; that of the median ridge has 

 numerous small oval transparent spots. The marginal spines are very wide apart 

 (110//), and comprise a single row of short conical spines. The stigmatic clefts are 

 recessed in the form of narrow deep cups ; each contains two short (27//) blunt spurs 

 at the base. «;>
