Ceroplastes communis, Hempel. 
Adult female scale oval in outline, dorsum convex; wax 
not shiny, pinkish white, usually covered with a black fungus, 
divided into seven distinct plates; hard and very thin, so 
that in the older specimens the derm is frequently exposed. 
When removed from the bark it leaves an oval patch of 
white wax behind. Length 6°25 millim. ; width 5°50 millim. ; 
height 4°75 millim. Denuded of wax the insect is oval ; 
dorsum convex, dorsal nucleus present, elevated, the other 
nuclei not distinguishable. Derm light yellow, shiny, not 
smooth, slightly chitinous, and with few pits. No humpsare 
present. Boiled in a solution of KOH it colours the liquid 
light yellow. The derm becomes softer and semitransparent. 
Antenne variable, usually of seven joints; frequently, 
however, an extra false joint is present. Length 460 millim. 
to 495 millim. All the joints except joint 3 bear hairs. 
Approximate formula: 4 (3.1 2) 7 (56). Length of joints: 
(1) 70-75, (2) 66-70, (3) 70-79, (4) 129-1383, (5) 35-40, 
(6) 35-40, (7) 40-46. Legs ordinary; length of joints of 
first pair of legs: coxa 155, femur and trochanter 245, tibia 
168, tarsus 114, claw 31, digitules of claw 48. Tarsal digi- 
tules slender, with expanded ends extending to the tips of the 
digitules of claw; the latter are wide and have round ex- 
panded tips. Rostrum well-developed, placed behind the 
insertion of the first pair of legs. Rostral loop short. 
Caudal horn very short and wide, inconspicuous. Anal ring 
with six long hairs. Stigmatal areas characterized by a 
horseshoe-shaped depression on the ventral surface, with 
about twenty conical spines and forty to fifty round spin- 
nerets. The margin of the body is thickly set with a double 
row of short sharp conical spines and a few longer hairs. 
The dorsal derm is homogeneous without any apparent 
glands. 
Eggs small, elliptical, smooth, shiny, almost white when 
laid, but becoming light yellow.
