orange in color. Its pale color and elongate exuvium will readily 

 separate it from all other scales on orchard trees. The insect passes 

 the winter with the mature females and the male scales. The males 

 hatch in early spring. The eggs are laid early in May, and the larvae 

 hatch in about ten days. The males again commence to issue by 

 the middle of June, and the females begin egg-laying by the end of 

 June. The second generation is full grown by the middle of August, 

 and these in time soon begin to lay eggs for the brood that will winter 

 as mature females and undeveloped males.

The male scale (fig. 11, c, d) is elongate, about three times as long 

 as broad, slightly wider behind than in front, with a median keel, and 

 snow white in color. The male scales appear to be most numerous on 

 the lower parts of the bijinches and near the base of the trunk and 

 often so matted as to make the trunk or lower branches absolutely 

 snow white. The peach scale is becoming common in many of the 

 Southern States and as far north as Pennsylvania. It infests plum, 

 cherry, and peach, and less commonly other plants.
