Yellow-breasted Shrike Robin (Eopsaltria australis). 

 White-throated Tree-creeper (Climacteris picumna [leucophcea]). 

 Starling (Sturnus vulgaris). 



It is due very largely to the Sparrow about Sydney that several species; 

 of Cicadas arc almost extinct.

A list has not been made of the very large number of birds feeding on beetles 

 or their larvae, with the two following exceptions, viz., wireworms and lady- 

 birds. Such a list would comprise nearly all our insectivorous birds. 

 Many beetles cause considerable economic loss, as, for instance, in the cases 

 of timber-borers and pumpkin beetles.
