Fig. 10. — San Jose Scale : a, pear showing the scales, natural size; b, 
female scale enlarged; B, section of limb showing scales natural size. (Howard, 
Yearbook, U. S. Dep. of Agr., 1894.) 
Remedies — While the trees are dormant use the same 
remedies as are recommended for the Scurvy Bark-Louse. 
In case it becomes necessary to treat the lice after the leaves 
are out, use kerosene emulsion or whale-oil soap of the or- 
dinary strengths and make hve or six applications at inter- 
vals of about five days. If an orchard, or even isolated- 
trees, become badly infested and the lice do not succumb to 
winter treatment, it will usually be better to cut down the 
trees and burn them completely. 
PUTNAM’S SCALE. {.Aspid iotio; anriiliis Putnam.) 
This scale resembles the preceding so closely that it is 
impossible to give characters that will enable one who does 
not possess a compound microscope to distinguish between 
them with much certainty. The small male scales of this 
species are not black, however, as in case of the San Jose 
scale. When either of these scales are suspected it will be 
well to send specimens to the experiment station for determi- 
nation. 
Remedies for this species are the same as for the Scurvy 
Bark-I.ouse mentioned above.
