AFRICAN SCALE INSECTS (COCCIDZ). 89 
are in all probability those of P. blanchardi, Targ-Tozz. These are pale buff or 
ochreous in colour, short and stumpy in form, and the pellicles are smoky green 
or bottle-green in colour. They do not, in any measure, agree with the male 
puparia of any known species of Chionasp/s with which I am familar. 
Chionaspis cassiae, sp. n. 
Female puparium.—White, very highly convex and distinctly mytiliform ; 
generally with distinct transverse layers of the dusky, yellowish brown, epithelial 
cells and long hairs from the food-plant incorporated with the secretion, Larval 
pellicles pale orange-yellow ; second pellicles paler, and generally completely 
covered by secretion. Length, 2—2°50 mm. 
Female, adult.—Apparently ovoviviparous, as several fully developed larvae 
were found in the body of the parent. Shape, normal. Rudimentary antennae 
with two rather long slender spines placed closely together so that they often 
appear as a single stout spine. Parastigmatic spines 5-7 in number, forming a 
small compound group near the orifice of the stigmata. Dorsal pores extending 
as far as the thoracic region; these organs are arranged, as usual, in scattered 
and somewhat indefinite bands broadening towards the margins of each segment, 
with the exception of the last in which they are placed much more closely 
together, forming definite narrow bands, widely separated in the median line. 
Pygidium with a similar band of pores, and five groups of circumgenital glands, 
the formula of which is as follows :— .

arranged in five bilateral pairs ; the first pair covering the lateral margins of the 
median lobes, being much the smallest. 
Puparium of male-—Pure opaque white; with widely separated transverse 
ridges or carmae, each ridge being curved towards the distal extremity of the 
puparium, Pellicles bright yellow. Length, 1-1°50 mm.
