THE COCCIDAE OP SOUTH AFRICA — II. 119 



length on the middle face is about equal to the width of the lobe. When not worn 

 down, Lj are notched on both outer and inner sides and the median extremity is 

 rounded. The outer margins of these lobes curve slightly outward, and from each 

 lobe a dense band of chitin extends into the pygidium for about the length of the 

 lobes. L 2 are about as long as 1^ but narrower, and usually notched on the outer 

 side ; L 3 smaller, often + conical. The plates are longer than the lobes (fig. 84) 

 and are finely divided at their extremities, the longest branches being nearest the 

 lobes. Circumgenital glands present, in four groups : —

70. Aspidiotus furcillae, sp. n. (Plate vi, fig. 85). 



Female scale small, about 1 mm. diameter, + circular, roundly arched, sordid 

 white in fresh material, but when older appearing dark brown to blackish brown 

 with rich red brown exuviae. The true colour of the scale is rarely seen, as nearly 

 all specimens are partly or wholly covered with the outer layers of bark of the 

 host-plant. The exuviae are central or nearly so. 



The adult $ is apparently viviparous, as mounted specimens contain many larvae. 

 Its body is broad pear-shaped, widest a little before the middle. The body wall is 

 thin. Antennal tubercle with one long hair and two short spurs. Extending into 

 the pygidium are two interrupted bands of chitin, the anterior portion being a little 

 outward from the posterior bands (fig. 85). L x large, strongly chitinous, with the 

 dense portion extending into the pygidium for a distance of a little more than the 

 length of the lobes. The median space is narrow, parallel-sided, apparently without 

 plates or spines. The median lobes are stongly indented on the outer margin and 

 faintly notched on the inner side ; outer margin of lobes rounded, with the outer 

 edge longer than the inner. L 2 and L 3 + rudimentary, with a broad base from which 

 arises a long stout spine, and the lobe proper, which is delicate and pointed. L 4 

 similar but generally shorter and more rudimentary. P long, broad, almost parallel- 

 sided, with the apex drawn out into two, 'or occasionally three, very long prongs. 

 The plates are apparently easily broken away, as many specimens have few left 

 when mounted. Parastigmatic glands 0. Circumgenital glands in four groups : —
