This is a common species in the neighbourhood of Sydney in 

 midsummer, and is known as the " Floury Miller" on account of 

 the quantity of silvery pubescence covering the body, which makes 

 it look as if it had been dusted with flour. It arrives somewhat 

 later than the other large cicadas, emerging in December and 

 is most plentiful about the new year; it has a wide range just round 

 Sydney, both in our gardens and bush lands.
