This species was taken by us in 1901 on a species of Hibiscus, 

 used as hedges. Mr. Geo. A. Bishop states that it is not only injuri- 

 ous to hibiscus, but infests oranges and other citrus fruits, and the 

 galba. It is liable to attack a great variety of trees, and is very 

 widely diffused.

This scale is very injurious to the olive and orange, etc. Accord-

 Hibiscus. It is liable to attack many other plants, as pear, apple, 

 apricot, plum, pomegranate, palms, coffee, rose, jasmine, etc.

 the cycad (Cycas revohfta), oleander, hibiscus, etc. In California it 

 has been found to attack the orange. It is also common on various 

 greenhouse plants.
