Hah. — Condobolin, N.S.W. (on Acacia pendnla ; specimens 

 ol)tained by shaking; W. AV. Froggatt). 



This is one of the free ps3dlids which run about on the branchlets 

 singly and never cluster togethei* in communities. Though I 

 have never bred them from the larvje, I ha\e noticed a stout 

 green pupal and larval ps3'llid thickly coated with white filaments 

 on the tip of the abdomen, which hides among the leaf-stalks; 

 this is probably the immature form of the insect.
