SCALE INSECTS (" COCCID^E ") OF AUSTRALIA. 51 



The female tests are always found upon the foliage ; they are broadly oval, 

 fcometimes slightly narrowed behind, convex, and resting upon the surface 

 of the leaf without forming more than a slight depression ; general colour 

 greenish yellow, with the darker insect beneath, giving the anterior portion a 

 brownish tint. The outer margin is beautifully fringed with an unbroken 

 band (in fresh specimens) of fine white glassy spines. Length, ^V of aii inch. 



From the wide range of this species, and the fact that its host plants are 

 all Australian, I do not think that it is identical with the European species, 

 . A. fimbriatum.
