132 CHAS. K. BRAIN. 



The chitin in the adult $ of this variety is much more dense, dark in colour and 

 often appears perforate. The third lobe is norma] as in lounsburyi and the other 

 characters are similar. 



In old specimens which have dried out the scales become uniformly greyish white, 

 and the covering of the second exuviae with the first exuviae attached is generally 

 flaked off so that the scales appear greyish white with brown centres.

Professor Newstead's description is as follows : — 



" Puparium of female. Circular, smooth and rather thin ; pellicles central, yellow 

 to yellowish-brown ; secretionary portion straw-coloured to ochreous white. 



" Diameter, T50-2 mm. 



" Female, adult. Strongly chitinised ; thoracic articulation very distinct, con- 

 striction at sides deep ; abdominal segments clearly defined by broad deep grooves 

 terminating before reaching the margin ; there are also several similar grooves on the 

 thoracic region, but they are very short and irregular, taking the form rather of gland- 

 tracts than true articulations. Pygidium (fig. 101) with three pairs of lobes ; the 

 second pair similar to the median pair, the third the smallest ; all are distinctly 

 striate, longitudinally. Squamae broad and rather coarsely divided. Spines very 

 short. Tubular spinnerets long and slender, some of them reaching almost to the 

 base of the pygidium. 



" Resembles Aspidiotus articulatus, Morgan, but may be readily distinguished by 

 the absence of the long serrated squamae at the margin of the pygidium.

Sudafr., p. 18, 1912. 



Professor Newstead's description is as follows : — 



" Puparium of female. Circular, thick, and opaque ; exuviae central or sub- 

 central ; larval pellicle golden brown to dark golden yellow, covered with a white 

 secretion, generally ; second pellicle red-brown, covered with secretion similar to 

 that of the larva ; secretionary portion in two equal zones of pale ochreous and white, 

 the latter marginal. Diameter, 1*75 to 2 mm. 



" Female adult. With a well-marked thoracic articulation, constriction at sides 

 great. Integument not highly chitinised. Antennae represented by an extremely 

 minute tubercle furnished with a long spinose hair at the base. Stigmata without 

 parastigmatic glands. Pygidium with a clearly defined lingula-shaped body of
