Pulvinaria. 265 
Young larva (jig. 2) very pale green. Eggs pale greenish, embedded in the 
cottony matter of the ovisac. 
On leaves, young branches, and fruits of numerous plants, amongst which 
may be mentioned coffee, tea, cinchona, Cztvus, Eugenia, Garcinia, Duranta, 
Tecoma, guava, myrtle, Alpinia, Antidesma, Ficus, Cardamomum. Frequently 
massed in such numbers as to hide the green parts of the plant. Abundant 
throughout the island at all times of the year. Recorded also from New 
Zealand, Hawaiian Islands, Formosa, China, California, and India. 
P. cupanie, Ckll., and P. “#cws, Hempel, are but doubtfully distinct from 
psidit. 
The species is kept in check, in Ceylon, by a minute Cecidomyiid fly, which 
breeds in the ovisacs and destroys the eggs.
