Ceroplastes rarus, Hempel. 
Adult female scale oval; dorsum very convex, conical, 
coming to a point; wax thin, dry, brittle, creamy white, 
divided into seven distinct plates—two lateral on each side, 
one dorsal, one on the anterior end, and one on the posterior 
end. Nuclei large, conspicuous, dark brown, oval; posterior 
plate with two nuclei. The plates are divided from each 
other by areas of brown wax. The wax in the plates is 
arranged in concentric layers, those on the dorsum round, 
those on the sides square. Numerous fine lines also radiate 
from the nuclei. Length 5°75 millim.; width 4°50 millim. ; 
height 4 millim. Denuded of wax derm hard, shiny, smooth,

each side of the caudal horn. Caudal horn small, short, dark 
brown, placed horizontally. Length5 millim.; width4millim.; 
height 3°50 millim. Boiled in a solution of KOH it colours 
the liquid light yellow. The dorsal derm remains chitinized 
and opaque. 
Antenne of seven joints, all but joint 3 bearing hairs. 
Length °350-391 millim. Length of joints: (1) 53-66, 
(2) 44, (3) 48-57, (4) 97-106, (5) 83-35, (6) 31-35, (7) 44-48. 
Approximate furmula: 4 13 7 2 (5 6) or 4 (1 8) (7 2) (56). 
Legs ordinary. Length of joints of the first pair of legs: 
coxa 133, femur and trochanter i191, tibia 123, tarsus 97, 
claw 22, digitules of claw 36. ‘Tarsal digitules very long 
and slender, with the ends widely expanded. Digitules of 
claw of equal size, large, wide, with widely expanded round 
ends. Rostrum placed nearer the second pair of legs than 
the first. Rostral loop short, not extending to the second pair 
of legs.

Ceroplastes cultus, Hempel. 
Adult female scale irregularly oval, truncated posteriorly ; 
dorsum convex, smooth, shiny, creamy white, divided into 
seven plates by bright brown lines. The wax is thin and 
hard, and slightly depressed about each nucleus. Dorsal 
nucleus oblong, large, the lateral and terminal nuclei small, 
subeircular ; all the nuclei are bright brown, with a small 
patch of white wax in the centre. ‘The caudal plate has two 
nuclei. The dorsal plate is the largest and subcircular in 
outline. Fine lines radiate from all the nuclei and a few 
concentric rings are also present. Around the lateral margin 
the wax is thicker and nearly white. Length 5 millim. ;
