Aleurodes bergi, Sign., has since been found and reared upon sugar¬ 
cane in Behar, and other species occur on castor, mango and tobacco. 
A full account of the first has been published by Zehntner (Arch. Java 
Suiker-industrie, 14, p. 939 [1896], with coloured figures). Figures of 
the undescribed species occurring on castor in India will be found on 
Plate LXXXL 
CocciDiE.— Mealy bugs and Scale insects. 
Male winged , with one pair of wings. Female wingless. Usually small 
insects, living motionless on plants and concealed or protected by a 
covering. Tarsus one-jointed with a single claw. 
Scale insects, while rarely attaining very small dimensions, form part 
of the great number of insects that are sufficiently small to escape general 
attention. Many are not more than one-twentieth of an inch in diameter. 
Others are distinctly larger, of the size of a pea, while a few of the largest 
Indian forms have a length of one-half and even two-thirds of an inch. 
None can rank among the large insects, whilst the giants of the family 
(Monophlebus , Walkeriana, Lecanium imbricans , etc.) are conspicuous 
only when abundant.
