90 ROBERT NEWSTEAD—OBSERVATIONS ON 
On Cassia floribunda ; Entebbe, Uganda Protectorate, 1. VIII. 1910 (C. C. 
Gowdey). 
The curious form of the male puparium should at once serve to distinguish 
this insect from any other member of the genus Chionaspis, typical forms being 
more or less distinctly tricarinate. In this species, however, there is no trace of 
the usual longitudinal ridges, which is remarkable, seeing that hitherto little 
variety has been found in the form of the male puparia. 
The female belongs to that section of the genus in which the median lobes are 
in close apposition ; it does not possess any very striking morphological characters 
but is apparently distinct. 
Chionaspis substriata, Newstead. 
On Palm; Entebbe, Uganda, 18. VI. 1909 (C. C. Gowdey). 
Chionaspis dentilobis, Newstead. 
Uganda (C. C. Gowdey). Food-plant not stated. 
Fiorinia africana, sp. n. 
Female puparium.—Somewhat ovate but suddenly narrowed posteriorly ; 
widest and very highly convex in the region just behind the larval pellicle. 
Colour varying from pure white to smoky grey ; the secretionary matter is pure 
white, but when the layer over the exuviae of the second stage female (second 
pellicle) is thin, the dark colour of the underlying insect shows through, giving 
the puparium a smoky grey tinge. Over-crowded examples of the puparia 
become distorted and irregular in shape as in other D1ASPINAE under similar 
conditions. Larval pellicle usually ochreous buff, often with a small bottle- 
green spot at the caudal extremity. Second pellicle piceous or dark castaneous 
sometimes with a dull crimson area in the centre, the colour is, however, very 
variable. 
Female, adult.—Pygidium (fig. 5) with an irregular arched group of circum-

genital glands near its articulation with the first (distal) free abdominal segment ; 
margin with (? several) simple quadrate lobes, and a number of short spines. 
Female, second stage (nymph).—Somewhat pyriform in shape, with the 
abdominal segments gradually tapering towards the pygidium ; each segment
