The galls are common upon the foliage of the bloodwood {Eucalyptus 

 corymbosa) in the coastal districts of this State. 



The galls are round, varying from half to three-quarters of an inch in 

 diameter ; green reddish or dull yellow, growing upon the leaves, either 



singly, or in groups of two or three, and 

 often quite aborting the infested leaves. 

 The chamber containing the female coccid 

 is at the base of the fleshy galls, with 

 the small basal orifice opening out on the 

 underside of the leaf. Adult female about 

 one-sixth of an inch in diameter, con- 

 rig. ioi.-A):eeiis praemoius, fichTa.dei. sisting of a shapeless irregularly rounded 



pale yellow mass, with no signs of legs 

 or antennae ; the anal appendage stout, cylindrical, dark brown, surrounded 

 at the base with a dark ring ; at the apex there are three slender finger-like 

 projections, holding a mass of gummy secretion, which protects the opening.

This is the flattened blister gall upon the foliage of the bloodwood Eucalyptus 

 corymbosa, found in similar localities as A. praemollis in the coastal districts 

 of New South Wales, but I have never found both these species upon the 

 same tree. 



The adult female gall is an irregular rounded blister about half an inch in 

 diameter, and swelling out slightly on either side of the surface of the leaf ; 

 the aborted tissue varies from pale yellow to reddish brown, with the apical 

 orifice small, circular, and on the upper surface of the leaf. 



The adult coccid is similar in form and structure to that of the preceding 

 species, but slightly larger and more flattened ; the anal appendage more 

 slender than in A. praemollis ; apparently solid, truncate at the tip, and 

 while fitting into the apical orifice, not quite level with the surface of the 

 surrounding tissue. 



, Schrader notices this gall in his paper, but apparently considered it to be. 

 a variety or abnormal form of his A. prcemolUs.
