size, with expanded ends; digitules of claw, one large the 
other smaller, both with widely expanded ends. Rostrum 
well developed, usually placed about midway between the 
first and second pair of legs. Rostral loop extending beyond 
the second pair of legs. Hach stigmatal area is charac- 
terized by twenty to twenty-five conical spines and as many 
spinnerets. Around the lateral margin of the body there is a 
simple row of short hairs set close together. Derm with a 
number of small glands.

bushes. 
Ceroplastes formosus, Hempel. 
Female scale rectangular; dorsum convex; wax bright 
lemon-yellow in colour, uneven, divided into seven distinct 
plates, situated two on each side, one on dorsum, one on the 
anterior end, and one on the posterior end. Dorsal nucleus 
large, white, usually covered with a black fungus; lateral 
nuclei not visible. The wax is lighter in the centre of 
lateral plates than on the edges, is hard and tough, and deeply 
depressed about the dorsal nucleus. Length 4 millim.; width 
3 millim.; height 2°75 millim. Boiled in a solution of KOH 
the derm becomes transparent and soft. Caudal horn 500 
millim. long, dark brown in colour. 
Antenne variable, of six joints, all of which bear hairs. 
Length *202—224 millim. Length of joints: (1) 31-35, 
(2) 26, (8) 70-79, (4) 18-22, (5) 22, (6) 35-40. Approxi- 
mate formula: 361 2 (4 5) or 3 (6 1) 2 (45). Legsshort. 
Length of joints of first pair of legs: coxa 75, trochanter and 
femur 93, tibia 75, tarsus 66, claw 18, digitules of claw 31. 
Tarsal digitules 44. Digitules of claw of unequal size, one 
large and wide, with expanded end, the other smaller and 
narrower. ‘Tarsal digitules very iong and slender, with 
expanded ends. Coxa with two short spines on the proximal 
end; the tarsus frequently has an incision on the margin, 
giving it the appearance of being jointed. Rostrum between 
the first pair of legs; rostral loop extends to the third pair 
oflegs. Anal ring apparently with six hairs. Hach stigmatal 
area is characterized by about twenty conical spines and a 
few round spinnerets. The conical spines are situated on the 
entire margin of the body, except in the cephalic and caudal 
regions. ‘I'he derm bears numerous small spinnerets.

of Hugenia sp.
