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-

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

the cyead ( Cycas revoluta), oleander, hibiscus, etc. In California it 
has been found to attack the orange. It is also common on various 
greenhouse plants.
