Observations on certain Gall-making Coccidce of Australia^ 



hy H. L. SCHRADER. 



[Eead 2nd June, 1862.] 



As a preface to my observations upon this family of the 

 Homoptera it will perhaps be as well to give a short review of 

 the modern classification of the Order. 



Westwood, following the views of Latreille, divides the Homo})- 

 tera of MacLeay into three primary Sections. 



1. Trimera. Tarsi 3 — jointed; antennce minute, setigerous ; 

 wings areolate. 



(The Cicada may be taken as the type of tliis Section.) 



2. DiMERA. Tarsi 2 — jointed ; antenna moderate, filiform, 

 5 — 10 — jointed ; wings subareolate. 



(The Aphis, so well known as the destroyer of our most 

 useful and admired vegetable productions, maj^ be considered as 

 the type of this Division.)
