^«6.— Cheltenham, Victoria (on Acacia pycnantha; C. French, 

 Junr.). 



The only specimens of this species that I have seen were upon 

 the large stout leaves of this Acacia. The eggs were scattered 

 about singly, and there did not appear to be many specimens upon 

 each leaf. 



PsYLLA LiDGETTi, Maskell. 



Trans. R. Soc. S. Aust. 1898, p. 5, pi. i., figs. 1-4. 



This species was named from specimens sent to Mr. Maskell by 

 Mr. Lydgett who found them on Acacia im.plexa at Myrniong, 

 Victoria, a wattle which does not grow about Sydney. 



This is a brown-coloured psylla with irregular patches of 

 reddish-yellow, the antennae and feet yellow ; eyes red. The 

 wings are clouded in a different manner from any of the species 

 of this genus that I have examined, and it is probably a local 

 species like many of the others. 



Mr. Lydgett has promised to send me some specimens of this 

 Psylla, but up to date I have not received them.
