This species was named the greedy scale by Prof. Corn- 

 stock on account of its infesting a large number of different 

 plants. In his work on scale insects (See Ag Rep. i88o) he 

 gives the following hosts: almond, quince, fig, willow, 

 eucalyptus, acacia and locust. In addition to these Co- 

 quillett'-^ gives the following: apple, pear, Myosporium, 

 birch, English laurel, maple. South African silver tree, 

 Rhainmis, Cal., walnut, holly, fuchsia, Cottonwood, camellia, 

 orange and lemon. In North America this species is found 

 principally in the lower austral and northern tropical zones. 

 It is not uncommon in the southern states and in California 

 and in the northern states is occasionally found on greenhouse 

 plants. It has been taken upon Osmanthns at Ames, Iowa.
