362 ROBERT NEWSTEAD. 



on the 6th and 7th ; terminal hairs short and stout. Legs strong, normal ; tarsus 

 of 1st pair nearly as long as the tibia ; two hairs on the trochanter. Stigmatic 

 clefts faintly indicated ; spines in a compact dense group consisting of from ten 

 to twelve, all of them much stouter and longer than the marginal spines, the imier- 

 most ones largest of all and flattened. Marginal spines simple, short and pointed, 

 very widely separated, excepting at the distal margin, where five to six are placed 

 much more closely together ; within the margin is a series of smaller spines, somewhat 

 irregularly disposed ; the chitinous disks upon which these hairs are seated are as 

 large as the marginal ones ; similar minute spines are thinly scattered over the 

 whole of the dorsum. Derm cells (fig. 13, b) very minute, with a central pore, and 

 in old, well stained examples these give the integument a speckled appearance ; 

 they are most numerous in the region of the anal lobes ; in younger examples these 

 appear as minute pores. Anal lobes (fig. 13, c) thick, obtuse and broadly romided 

 distally ; dorsal surface with several widely separated hairs. Anal cleft very short. 

 Anal ring with ten hairs ; retractile tube with not less than eight hairs ; ten or 

 more may be present. 



Length, 3-5-5-1 mm. ; height, 2-1-3-2 mm. (dried examples). 



Female, second stage. Much more elongate than the adult. Integument, when 

 dry, deeply wrinkled ; colour dusky buff, generally with conspicuous black spots. 

 Antemiae of seven segments. First pair of legs scarcely longer than the antennae ; 

 tarsi with a clearly defined constriction dorsally. Marginal spines as in adult. 

 Stigmatic cleft (fig. 13, d) small ; spines very like those in the adult, but seem to 

 be fewer in number and not so closely packed together. Anal lobes not differing 

 markedly from those of the adult. 



Larva. Stigmatic spine long, stout and curved, marginal hairs simple and nearly 

 as long as the corresponding spines in the adult female. Hair of the anal lobes 

 about equal in length to the legs.

Lecanium (Saissetia) persimile, sp. nov. 



Female, adult. Not differing appreciably in its external form, colour, and density 

 of chitin from Lecanium (Saissetia) oleae (Bernard), but in two examples the dorsum 

 was covered with a fine dusky-white, mealy secretion. The median longitudinal 

 and two transverse ridges, forming roughly the letter H, well marked in two specimens, 

 but absent in another. Anal cleft completely fused. Anal lobes attenuated, outer 

 angle broadly romided, inner edge much the longest ; apex bluntly pointed, with 

 one or two short spines. No stigmatic clefts ; spines three, the central one slightly 

 more than twice the length of the laterals. Antennae well developed, of eight 

 segments. Legs rather slender ; lower digitules very robust, incrassate proximally, 

 dilated distally. Derm thickly studded with small, but weU-defined, oval and 

 translucent cells ; these are much more crowded together at the marginal and also 

 larger.

 The one salient character by which this Coccid can be distinguished from Lecanium 

 {Saissetia) oleae, (Bern.) is the non-reticulated appearance of the derm. In all
