. Annual report. Entomological Society of Ontario; Insect pests; Insects. Fig. 83.—San Jose' Scale, female enlarged and part of infested branch (life size.) who are quite familiar with the latter. My own manner of distinguishing between these two scales is to first observe if the disc is circularly wrinkled and the elevation in the centre surrounded by a depressed ring ; if the scale is very flat, or if it appears to rise.
