(12) Aspldiotus cameUi<p Sign. 



Found at Augusta, Tliomasville, and Okapiico, Ga., on peach, grape, 

 heliotrope. Arbor- vitse, and Chilopsis linearis. 



(13) iJktspis araygdali Tryon. 



This species occurs at Irby, Ashburn, Thomasville, and Bainbridge, 

 Ga., on peaches and plums, and on lilac at Ashburn. It ranks next 

 to the San Jose scale in economic importance when once it becomes 

 established in an orchard. On October 6, 1898, the writer found this 

 scale infesting an orchard of 25,000 peach trees at Irby, Ga. ; 10,000 

 of these trees were fairly encrusted and in a d3dng condition. Being 

 beyond the hope of recovery, they were dug up. The insects had 

 spread to an adjoining orchard of 12,000 trees, where they were doing- 

 immense damage. The case at Ashburn involved about 1,000 trees, 

 all of which were destroyed by this pest. 



In 1898 the writer observed that the first brood began to issue the 

 12th of March, and by the 1st of April the young were about all 

 hatched. As a remedy we use kerosene in mechanical mixture with 

 water at the rate of 20 per cent applied in the fall after the foliage is 

 shed from the trees, or 10 per cent applied in the spring immediately 

 after the first brood has issued.
