 Chionaspis stanotophri, Cooley, Spec. Bull. Mass. Exp. Stn., p. 35, 1899. 

 Professor Cooley's description, omitting plate references, is as follows : — 



" Scale of Female. — Length 2 - 2-2'6 mm. Moderately elongated, distinctly 

 convex, firm in texture, clear white in color. Exuviae "8 mm. long ; lemon-yellow 

 or orange-yellow in color. 



" Female. — Three pairs of lobes are present. Median pair rounded, divergent, 

 striate, entire ; separated at their bases by a distance nearly equal to the width of 

 one of the lobes. Lobules of the second pair rounded, entire, striate. Third pair 

 varying in degree of development ; composed of two broad, short, striate, entire 

 lobules. The lobes are very slightly, if at all, darker than the remainder of the 

 pygidium. In general appearance the median lobes resemble those of pinifoUae 

 but they are further apart. The gland-spines are arranged as follows: 1-2, 1-2, 

 1-2, 3. There are four distinct spines at the base of each of the median lobes, two 

 above and two below. Second row of dorsal gland-orifices represented by the 

 anterior group consisting of 1-4 orifices. Third row with 4 orifices in the anterior 

 and 5-6 in the posterior group. Fourth row with 4 orifices in the anterior and 5-6 

 in the posterior group. Median group of circumgenital gland-orifices, 7-12 ; anterior 

 laterals, 18-24 ; posterior laterals, 15-17. 



"Scale of male. — Length, 1-1 - 2 mm.; distinctly tricarinate. Exuvia lemon- 

 yellow or brownish, occupying scarcely one-third the length of the scale." 



Habitat : On buffalo grass {Stanotophrum glabrum), Cape Town. On Eulalia 

 gracilis, Maritzburg ; collected by A. Kelly, April 1915. On Ehodesian lemon grass, 

 Richmond, Natal ; C. Fuller, 1899. On grass (sp. indet), Zoo, Pretoria, and on grass 

 (sp. indet) Ceres, OP. 



Collection Nos. : 144-144d. 



137. Chionaspis capparisi, sp. n. (Plate xvi, fig. 154). 

 Scales clustered on the twigs and stems of the host-plant. 



The female scale is about 2 - 2 mm. long, comparatively wide for its length, 

 moderately convex, widest about the middle, clean specimens appearing slightly 

 glossy but felted. Exuviae brown. In some cases the second exuviae appear to 

 be covered with a very slight film of whitish secretion, but as a rule they are naked. 

 Male puparium white, non-carinated, exuviae yellowish or yellowish brown. 

 Adult $ viviparous, mounted specimens containing numerous well-developed 

 larvae. Adult $ mounted, about 1*5 mm. long, comparatively wide, widest a little 

 behind the middle, narrowest at anterior end ; margin regular ; abdominal segments 

 not produced and but faintly indicated at the margin ; body faintly chitinised. Lobes 

 small and inconspicuous, as figured (fig. 154). P long, simple, dagger-shaped. 

 Circumgenital glands in 5 groups : —
