Prof. W. M. Wheeler told about a mass of saw-fly larvae, 
which he had observed in South America, moving slowly through 
the wet grass like a single animal. Mr. C. W. Johnson called 
attention to a similar habit in the dipterous genus Sciara in 
. which the larvae cluster together in a long narrow mass which 
moves along like a worm. See vol. 29, Nos. 4-6.
