Flah. — Australia (Westwood); Ash Island, near Newcastle,

The female resembles the male, but is somewhat smaller; and 

 the abdomen, while robust, is not inflated. 



This curious insect was originally described from Ash Island, 

 where they were said to be very abundant in several orange 

 orchards, resting in the day and calling with a loud, deep guttural 

 'r,' continued incessantly with vibrations, just before twilight; 

 and appeared about September. The specimens in all the 

 Museum collections seem to have come from the same locality. 

 We have had it from Glen Innes, where it is said to frequent 

 the willow trees; one specimen was taken on a low shrub on the 

 Ballina Road, near Lismore; another very large male is in the 

 Brisbane Museum Collection.
