of an inch in thickness, containing over 1000 pale pink larval 

 tubes, each of which is a distinct individual tube separated from 

 any other at the tip. 



^a6.^Wingham, Manning River (Mr. William Allan). 



The specimen from which this is described was received with 

 the note that it was not uncommon in that district. It consisted 

 of single large Eucalyptus leaf carrying five female galls, sur- 

 mounted with gall masses nearly as large as the one descril^ed, 

 with several smaller ones, all of which sprang from the edge of 

 the midrib of the leaf. 



I have another variety of this gall obtained l^y the Rev. T. W. 

 Alkin near Campbelltown, which is much more uniform in shape 

 than the former; in this specimen there are six bright pink coloured 

 galls springing from either side of the midrib of a very slender 

 Eucalyptus leaf; the female gall is not more than half the length, 

 the male gall mass much more funnel-shaped, containing on an 

 average about 100 male tubes in each mass. 



The gall described as the male of B. Thorntoni is another 

 variety close to the Campbelltown one, of which I have had four 

 specimens from around Wallsend.
