 the latter date those in the green and yellow boxes were all 

 found to be dead and only one was alive in each of the others 

 (black, red, blue, white). On November 7, one fresh larva was 

 put in both the green and yellow boxes ; at the same time twenty- 

 four strips of colored paper, measuring one by fifteen millimeters,

 built were removed and the larvae were given a new start with 

 twenty-four fresh papers. 



The colors of the papers from which these larvae made cases 

 are shown in Table V. No evidence of selection of papers colored 

 to match the background is indicated by the results. 



Even though the larvae did not select papers for their tubes 

 which matched the background, it seemed possible that the
