EXPEfilMENTS ON A QUEEN ANT. 197 



ox)aque porcelain, one of violet, and one of red glass, 

 all of the same size. The result is shown below. 



_ j pupae were taken 

 ( under red glass 



Total 90 88 



Obviously, therefore, the ants showed no marked 

 preference for the porcelain. On one, but only on one 

 occasion (Obs. 9), most of the pupae were carried under 

 the violet glass, but generally it was quite neglected. 



I now tri«d a similar experiment with porcelain and 

 yellow glass.
