exuviae showing through the thin layer of secretion. The scale is somewhat 

 translucent. 



Adult $ small, about 1 mm. long, considerably longer than broad, evenly rounded 

 in front, hyaline, except the pygidium, which is slightly yellow. The segmentation 

 is indistinct and the margin of the body + regular. The antenna! tubercles are small, 

 with one very long seta, which is five times the diameter of the tubercle in length. 

 There are three pairs of well-developed lobes, the median pair as broad as long, 

 symmetrical, with the sides rounded and narrowing towards the pygidial margin. 

 There is a distinct notch on each side and the apex is evenly rounded. The apical 

 half of all the lobes is striate. L 2 somewhat similar, smaller, with the notch on the 

 outer side more prominent than that on the inner. L 3 about half the size of L 2 , 

 similar in shape. The plates are broad, with a long terminal fringe, except P 4 , 

 which are broad at the base with a long narrow projection, which is + toothed on 

 its outer margin. The first two plates of P 4 are almost four times as long as L 3 .

Remarks : This species is similar to A. britannicus and orientalis, Newst., in some 

 respects, but is easily distinguished by the slight difference in the size of the scale, 

 the shape of the body, and the character of the glands and plates, especially P 4 .

75. Aspidiotus kellyi, sp. n. (Plate vi, fig. 86). 



The scale of the adult $ is about 2 mm. in diameter, + circular or slightly elongate, 

 flat to slightly convex, rather robust, faintly buff or brownish in colour, with almost 

 central exuviae, which are covered ; but in rubbed specimens they appear metallic 

 yellow to bronze in colour. Seen from below the second exuviae are yellow. The 

 ventral scale is extremely delicate and remains attached to the leaf. The tissues 

 below, and around the scales, are of a rich purple tint. 



The cj puparium is flat, about 1 mm. long, somewhat elongate, often with the ends 

 slightly pointed, dull light brown in colour with paler margins. Exuviae covered 

 yellowish. 



Adult $ bright yellow, long, pear-shaped ; when dry, dull deep brown to blackish. 

 When boiled and cleared the insect is small, almost 1 mm. long (containing young), 

 regularly pyriform, with margin regular, i.e., without prominent margins to the 

 abdominal segments. The posterior extremity is rather abruptly narrowed to the 

 pygidium. The mouth-parts are comparatively large and broad ; the antennae, 

 situated near the anterior margin, small, each composed of a + elongate tubercle 

 and one long curved bristle. Parastigmatic and circumgenital glands absent. The 

 pygidium appears truncate from the fact that the median lobes and the six adjacent 

 plates are deeply recessed in a + rectangular depression between the large second 

 lobes. There is a large strong spine at the outer margin of each lobe. Beyond the 

 third lobes the margin is + fringed with broad, short plates, of which there are 

 probably four or five, but the plates in this species are so delicate that out of eight
