THE COCCIDAE OF SOUTH AFRICA — II. 133 



chitin on the central surface, the apex of which points towards the hind margin. 

 Circumgenital glands obsolete. Dorsal pores small, numerous, scattered over the 

 whole of the pygidium. Anal orifice placed a little posterior to the lingula-shaped 

 body. Fringe of pygidium [fig. 102] with two pairs of large lobes, the third pair 

 obsolete. Squamae broad and digitate ; these organs are not, however, very clearly 

 defined. 



"Length, 1*50 mm. 



" Easily distinguished by the singular tongue-shaped mass of chitin on the pygidium. 

 It is nearly related to Selenaspidus magnus, Lindgr., but this species has the integu- 

 ment much more highly chitinised, is slightly larger, has a very wide vaginal orifice 

 and the tongue-shaped body is entirely absent. 



" Habitat : Sudafrika bei Riet Tinkas (sudlich von Salem am Swakop), Sept. 1903, 

 L. Schultze. Auf Euphorbia aff. virosa, Willd." 



This species is not represented in the Division collection. 



88. Aspidiotus (Selenaspidus) pumilus, sp. n. (Plate vii, fig. 107). 



Scale of adult $ about 1"6 mm. in diamf^r, almost circular, margins flat, depressed, 

 centre roundly and flatly conical, dull, g j brown, with yellow exuviae. 



Puparium of <J smaller, narrower and elongate, of same colour and texture as the 

 $ scale. 



$ viviparous. 



Adult $ (mounted) small, largest specimen seen measuring 1*2 mm. long and 1"1 mm. 

 broad across the angles of the cephalothorax. The body is entirely chitinous and is 

 chitin brown in colour. The cephalothorax is flatly rounded, more than twice as 

 wide as long, and the V-shaped sides of the articulation extend inwards for about 

 one-tenth the width of the body. The segmentation of the body is distinct on the 

 middle part, but does not extend to the margins. The antennal tubercles are large, 

 disc-like, with one long hair. Before the chitinisation of the body is quite complete 

 there are two well-defined series of hyaline patches, one in a curve in the region 

 of the vulva (in optical section) comprising six long oval spaces, and another in the 

 region of the mouth-parts. Parastigmatic glands 0. The vulva is wide, 180 jn, 

 and is situated anterior to the anal opening. The pygidium as illustrated (fig. 107). 



Circumgenital glands 0. Formula : P 15 L x , 2P 2 , L 2 , 3P 3 , L 3 , 2-3P 5 . 



Habitat : On New Zealand flax (Phormium tenax, Linn.), Stanger, Natal ; 

 collected by C. Fuller, 11th December 1903. 



Collection No. : 224. 



89. Aspidiotus (Selenaspidus) griqua, sp. n. (Plate vii, fig. 105). 



Scale of adult $ about 1*5 mm. long, almost circular, but appearing elongate 

 in the direction of the length of the twigs because it is so much arched, buff to 

 brownish, matt, + smooth, shell-like, with exuviae covered. The first exuviae 

 ar,e central and are usually covered with a small circular area of secretion which is 

 paler, or almost white. In rubbed specimens the first exuviae are brown. The 

 second exuviae are covered with a layer of secretion similar to that of the scale, but ' 

 their outer margin is often indicated by a line of paler colour.
