IV point to an opposite conclusion. The larvae in this 

 set were those used in the transference experiments : in 

 the table I have repeated the results of B (Table III) for 

 comparison. 



In the third set, the larvae were placed during pupation 

 in compartments lined with variously-coloured papers and 

 leaves. The results, so far as they go, seem to show that 

 the pupae have a considerable power of adaptation, but as 

 in this set I omitted to note the previous history of the 

 larvae (they were taken at random from various environ- 

 ments), there is no real evidence of the extent to which 

 the pupal colours are independent of the larval. I hope 

 to repeat this experiment with more success next year.

IV. Note on some experiments mi 0. bidentata. 



In the summer of 1909 I experimented with about 20 

 bidentata larvae given to me by Prof. Poulton. The 

 results are not worth giving in detail, as the forms pro- 

 duced were exactly the same as those already obtained 

 and described by him.*
