The Cherry Scale, Aspidiotus Forhesi (Johnson). Figs. 19 and 20. 



The Cherry Scale, although found in several localities in Ontario, has 

 not yet, with one or two exceptions, been reported as doing much damage. 



The adult female scale is circular, nearly smooth, slightly convex, 

 about 1.3-1.5 mm. in diameter, and has the exuviae usually centrally situ- 

 ated. The general color varies from a yellowish brown to a greyish yellow. 

 The exuvial part is usually orange.
