 the collector who took the larva in Java. (These Proceedings, 

 1917, xlii., pp.51-54, and Pl.iv., figs.31-33). 



Mr. Fletcher exhibited five portions of typical, water-storing 

 Mallee-roots, and one of two bottles of root-water from South 

 Australia, received from Mr. H. S. Crummer, through the kind 

 co-operation of Mr. T. Gill, of Adelaide, and Mr. G. Murray, of 

 Fowler's Bay, S.A. 



Dr. R. Greig-Smith oflt'ered some observations, based on a pre- 

 liminary examination of one of the two samples of water obtained 

 from Mallee-roots.
