THE COCCIDAE OF SOUTH AFRICA — II. 129 



Pygidium as illustrated (fig. 96). Circumgenital glands 0. Formula : 2P P L p 

 2P 2 , L 2 , 3P 3 , L 3 , 2-3P 4 . 



Habitat : This scale has been recorded on a large variety of plants, but an examina- 

 tion of the material reveals the fact that most of the records refer to A. lataniae and 

 not A. rapax. It is known on Euonymus, Acacia melanoxylon, and a native tree from 

 Johannesburg.

83. Aspidiotus (Hemiberlesea) lataniae (Sign.) Green (Plate vi } fig. 93). 

 Aspidiotus lataniae, Sign., Ann. Soc. Ent. Fr. (4) ix, p. 124, 1869 ; Green, Ent. 



Mo. Mag 1 . (2) x, p. 181, 1899. 



Scale of adult 9 arched, circular to one-sided to elongate, with exuviae near one 



side. Whitish or greyish brown, about 2 mm. diameter, exuviae blackish. This 



scale is very much like that of A. rapax, but is usually flatter and the exuviae strike 



one as darker in looking over a lot of material. Pygidium as illustrated (fig. 93). 



Circumgenital glands in 4 groups : 



3—6 3-6 

 5—10 5—10 

 Lobes and plates as in Aspidiotus rapax, from which it is readily separated by the 

 presence of circumgenital glands. 



Habitat : On a large variety of plants throughout the Union, including vines, rose, 

 box, palm, camellia, etc.

84. Aspidiotus (Hemiberlesea) mitchelli, Marlatt. 



Aspidiotus (Hemiberlesea) mitchelli, Marlatt, Bull. U.S. Dept. Agr., T.S. 16, 

 part 2, p. 22, 1908. 



Professor Marlatt's description is as follows : — 



" Scale of female : Length 1"5 mm ; subcircular to broad oval, strongly convex, 

 and of the general camelliae (rapax) type ; secretionary matter rather dense, color 

 dull yellowish, due chiefly to the extraneous matter taken up from the surface ; 

 exuviae yellowish-brown, near the anterior and usually covered. Ventral scale a 

 distinct white flocculent patch, thinnest at the centre. 



" Scale of male : Similar in general appearance to that of the female, but of the 

 normal elongate shape. 



" Adult female : Normal top-shaped, 0"75 mm. in diameter ; in balsam hyaline ; 

 anal plate a little more yellowed than body, broad, not produced ; three pairs of 

 lobes ; median lobes truncate, not converging, with two lateral shoulders, separated 

 by a lobe's width, relatively much smaller than the lobes of camelliae (rapax) ; second 

 lobe minute, spear-shaped, often with outer lateral shoulder ; third lobe narrow, 

 spiniform ; thickenings of first and second incisions present, subequal, and together 

 with lobes a little more yellow than the pygidium, but not strongly chitinised ; plates 

 numerous, long, filiform, central ones simply branched ; spines short, inconspicuous ; 

 basal dorsal thickenings not strongly developed or chitinized ; anal opening much 

 larger than median lobes, broad oval, about one lobe's length from tip ; paragenital
