156 NOTES ON AUSTRALIAN CYNIPID^ 



Several trees on the South Head Eoad near Vaucluse are 

 attacked year after year, and I have taken galls from them for 

 the last three years ; they are ripe about the end of October. 

 This Cynips does not seem to be much attacked by parasites, and 

 is easily bred from the gall. Another tree infested with this gall 

 grew in the late Sir William Macleay's garden, but the galls were 

 always very small, and it was only on breeding the Cynips out 

 that I proved them to be the same species. This is not a common 

 gall, and I only know of it in these two localities. 



Locality : Elizabeth Bay and Rose Bay.
