THE COCCIDAE OF SOUTH AFRICA. 2.3 



220. Lichtensia asparagi, sp. n. 



Female ovisac about 45 mm. long, elongate, narrow and very convex, sordid 

 white in colour, thin but dense, with the anterior extremity open, exposing the 

 front portion of the dry female. 



Male puparium moderately large, elongate, very convex, with perpendicular 

 sides, thin, semi-opaque, dorsum flatly rounded, entirely without median plate. 

 There is a faint indication of sublateral lines, otherwise the surfaceis uniformly sbippled. 



Adult $, mounted, broad oval, about 4 mm. long, with the two extremities 

 about equally rounded ; anterior extremity not produced. 



The integument appears remarkably free from conspicuous glands or hairs. 

 Maigin with a single scattered row of short sharp curved spines. Stigmatic spines 

 stout, somewhat curved, with rounded ends. 



Antennae 8- jointed, in one antenna examined 9- jointed, with the following range 

 in ,a : (1) 35-48, (2) 57-60, (3) r38-78, (4) 51-71, (5) 40-61, (6) 30-37, (7) 25-34, 

 (8) 30-38. 



Leg I : coxa 88, femur + trochanter 228, tibia 190, tarsus 102, claw 24/<. 



Anal plate about 185/i long, with longitudinal folds. 



Habitat : On Asparagus capensis, L. (Liliace^e), Eastern Cape Province. 



Collectioyi No. : 131. 



Genus Filippia, Targ. 

 Female flat, oval, legs and antennae normal. Side of body and dorsum witli 

 numerous tubular glands. Female, at maturity,, entirely enclosed in a flat felted 

 sac which, after oviposition, serves as an ovisac. 



221. Filippia chilianthi, sp. n. 



Adult 5 entirely covered with a dense, closely felted layer of white secretion, 

 about 6 mm. long and 3 mm. broad, ± regularly oval, with the dorsum moderately 

 convex. This secretionary layer is secreted slowly from all the upper parts of the 

 body, the glands concerned being scattered. This is not the case in the Pseudo- 

 cocciNAE, in which the ovisac is formed by secretionary glands in the posterior and 

 marginal portion of the body only. Little or no secretion appears on the ventral 

 surface, so that the leaf or twig forms the floor of the sac ; the marginal secretion 

 becomes attached and entirely encloses the $. As oviposition proceeds the body 

 shrinks away from the posterior end of the sac which becomes almost filled with ova. 

 At death the dry shrivelled body of the $ occupies a small portion at the anterior end. 



Prior to secreting the ovisac the $ is from 4 to 5 mm. long, and rather more 

 than half as wide. The sides are almost parallel for more than half the length of 

 the body, the posterior end appearing broadly rounded, and the anterior end more 

 pointed. In colour it appears greyish brown with a lighter median, flatly rounded, 

 keel. When seen under a hand-lens, however, it is noticed that the ground-colour 

 of the body is yellowish, and semi-transparent, speckled with black. The anal cleft 

 is short, with the sides closely adjacent. The anal plates are small and brown. The 

 lower surface is slightly concave, greasy-yellowish in colour, the black speckling of 

 the dorsum only showing faintly through at the extreme margins. The stigmatic 

 bands are represented by two short faint white lines on each side.
