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 larve 
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 branches 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.
