white. Wax not shiny, slightly roughened by radial furrows 
and depressions, not brittle and not divided into plates, but 
is slightly thickened around the lateral margin. Length 
4°50 millim.; width 3 millim.; height 2°60 millim. Denuded 
of wax the derm is hard, shiny, light brown in colour, with 
minute spots of darker brown. ‘There are two slight humps 
on each side and one on the dorsum. Caudal horn sharp, 
short, scarcely -500 millim. long, dark brown in colour. 
Length 3°50 millim.; width 2°25 millim.; height 2 millim. 
Boiled in a solution of KOH it colours the liquid pink and 
makes it turbid. The derm remains hard and semitrans- 
parent. 
Antenne variable, of seven joints, all except joint 3 bearing 
hairs. Length -273-307 millim. Length of joints: (1) 44, 
(2) 44, (3) 44-48, (4) 66-79, (5) 22-31, (6) 22-26, (7) 31- 
30. Approximate formula: 43(1 2) 7(5 6) or 4 (8.1 2) 7 (56). 
Legs ordinary. Length of joints of first pair of legs : coxa 79, 
trochanter and femur 182, tibia 123, tarsus 79, claw 22, 
digitules of claw 35. ‘Tarsal digitules long and slender, with 
expanded ends. Digitules of claw large, with widely ex- 
panded ends. Rostrum large, situated just behind the first 
pair of legs; rostral loop extending a little beyond the second 
pair of legs. Hach stigmatal area is characterized by about 
thirty blunt conical spines and the same number of large 
round spinnerets. ‘The lateral margin bears a simple row of

Genus TECTOPULVINARIA, Hempel. 
Adult female secreting an ovisac like in Pulvinaria. 
Dorsum entirely covered with a white felt-like secretion. 
Antenne of eight joints.

Tectopulvinaria albata, Hempel. 
Adult female oval; dorsum convex, entirely covered with 
a white felt-like secretion, which is evidently in two parts, 
the first around the margin, the second covering the dorsum ; 
this latter portion has the appearance of being secreted in 
concentric layers. Over the secretion on the dorsum there is 
usually a thin transparent scale, through which the dark 
brown dorsal nucleus can be seen. Frequently the secretion 
is elevated around the edges of the scale, leaving the middle 
of the dorsum depressed. In the older specimens the scale
