mealy. Colour in alcohol dull crimson ; venter terracotta red. Derm of venter 
thickly studded with short stout spines, scattered between them are numerous small 
circular spinnerets, and at greater intervals large, clear, circular glands ; besides 
these there are also a number of large subcutaneous bell-shaped organs (? glandular) 
having a finely reticulated lip ; the relatively small area protected by the secretionary 
operculum almost covered with circular spinnerets, and arising from between them 
many slender hairs. Thoracic spiracles large. Antennae of 10 segments, of which 
the terminal one is much the longest. 
Length 12-17 mm. ; width 8-12 mm. ; height 6-8 mm." 
Habitat : On M'sasa-tree {Brachystegia ranclii), Macequece, Portuguese 
East Africa, in association with A. maximus. Sent to Mr. Lounsbury,

Larva : About 0-8 mm. long, dark reddish-brown, active, dorsum and 
margins with numerous long delicate erect waxy or silky-looking filaments, 
which no doubt aid in distribution. 
? Young : 10 mm. long, very flat and wrinkled (Fig. 50). Antennae 
10- jointed similar to those of the adult ? . 
? Adult : " Female adult. Castaneous when dry, pale yellowish-brown to dark brown 
in alcohol. Ovate, slightly narrowed in front, convex above ; more or less flat ventrally ; 
dorsum with 3 rows of deep and rather widely separated pits arranged in zones and taking 
the contour of the margin ; within the zones on the thoracic area are several other similar 
pits, and the cephalic area has two more or less distinct and slightly divergent carinae. 
Margin with a series of large white tooth-like waxen appendages measuring on an average 
3 mm. in length : 29 of these appendages were present in one individual, and this number 
may be taken as approximately correct ; but they are rarely retained in old adults. 
Ventral (genital) orifice covered by an operculum or ' secretionary flap' (Newstead), as in 
A$pidoproctus pertinax Newst. Legs extremely short. Antennae broken away in the 
examples submitted. Dorsal epidermis thickly studded with circular spinnerets and 
large irregular ovate, clear, glandular spaces resembling the glands in certain species 
of Lecanium ; there are also numerous minute spines attached to disc-like bases ; the 
gland-tracts corresponding to the pits i^ the non-macerated examples, are much more 
chitinized than the surrounding integument and are furnished with a number of circular 
spinnerets. Ventral epidermis clothed with rather long stout spines, interspersed with 
small circular spinnerets and large circular pores ; besides these there are a number of 
minute compound glands surrounded by dark chitine, these are much more numerous in
