Genus CEROPLASTES, Gray. 
Ceroplastes campinensis, sp. n. 
Adult female scale light yellow in colour, irregular, oval in 
outline. Dorsum irregular, usually with three rounded humps, 
one anterior and two posterior. Dorsal nucleus alone present, 
depressed, slightly darker in colour than the surrounding wax. 
The individuals vary considerably, the very young specimens 
showing the three humps distinctly; while in the older 
specimens the dorsum becomes more convex and the humps 
are less conspicuous. ‘There are also specimens that are very 
irregular and have the dorsum ornamented by a larger number 
of humps. Not divided into distinct plates. Length about 
4 millim.; width 3 millim.; height 2°50 millim. Very old 
specimens are frequently larger. The widest part is posterior 
of the middle. On each side, at the stigmatal areas, there 
are two filaments of white wax that grow out at right angles 
to the body, often attaining a length of 1°25 millim. 
Boiled in a solution ot KOH, it colours the liquid carmine. 
Freed from wax, the adult female is convex, derm light brown ; 
caudal horn very short, dark brown in colour. There are no 
distinct tubercles present, but the dorsum is slightly lobed, 
being wider posteriorly than anteriorly. Around the ventral 
margin there is a narrow flange, which is slightly indented 
at the stigmatal areas. Derm chitinous, semi-transparent. 
Length 3°25 millim. ; width 2°50 millim. ; height 2°25 millim.

Length -241—252 millim. Length of joints in w: (1) 42, 
(2) 85-42, (3) 84-98, (4) 17-21, (5) 21-24, (6) 28-35.
