nucleus ; on the margin and anterior end the colour is lighter. 
A number of fine lines radiate from the nuclei. Dorsal 
nucleus much depressed, but the wax grows over it from 
behind, thus forming a hood. ‘The anterior end of the scale 
is acuminate, the posterior end truncate ; both ends are slightly 
notched. The inside of the wax is salmon-pink in colour. 
In the older specimens the radiating lines and concentric 
rings become obsolete and the wax bleaches to a creamy 
white. Removed from the bark it leaves a scale of white wax 
behind, Length 8°25 millim., width 7°50 millim., height 
5°75 millim. 
Denuded of wax the derm is shiny, salmon-colour, not 
very hard, with two prominent humps on each side, one 
hump on the dorsum, and a small one on the anterior end. 
Caudal horn small, broad and flat, black. Dorsum longitu- 
dinally striate, with a row of deep gland-pits on each side. 
‘The abdominal margin is slightly granulated. Boiled in a 
solution of KOH it colours the liquid a light pink. In the 
old specimens the derm is of a chocolate-brown colour and 
the humps are nearly obsolete. Length 4:50 millim. ; width 
2°50 millim.; height 1°75 millim. 
Antenne of six joints, all bearing hairs. Length *200 to 
220 millim. Length of joints: (1) 35-40, (2) 26-31, (3) 66- 
70, (4) 18, (5) 22-26, (6) 31-35. Approximate formula: 
316254 or 3 (16) (25) 4. Legs ordinary. Length of 
joints of first pair of legs: coxa 70, trochanter and femur 120, 
tibia 75, tarsus 48, claw 18, longest digitule of claw 26. 
The tarsal digitules are very long and slender, with ex- 
panded ends ; one of the digitules of claw is large, wide, with 
rounded expanded tip; the other is about half as large. 
Rostrum large, situated between the first pair of legs. 
Rostral loop long, in some specimens extending to the third 
pair of legs. Each stigmatal area is characterized by about 
twenty short bullet-shaped spines and by sixteen to twenty 
large round spinnerets, ‘lhe lateral margin of the body 
bears a few short hairs. Some small glands are scattered 
over the dorsal and ventral derm.
