These scales were taken in masses of about 100, and the scales con- 
taining eggs were counted. The mass consisted chiefly of broken, 
parasitized, empty scales ; some young brood recently settled. 
No accurate count could be made of any but scales with eggs. 
Some scales of P. pergandii were present. A large number of 
males had attained their perfect form. These trees were sprayed 
with solution 1-40 ; weather cold. Examined October 24; labels 
were illegible; some eggs and larva? living were found on all.
