 the relative positions as before. The nest contained about 50 

 larvae and pupae.

Thus in every case the larvae and pupae were brought under the 

 yellow or the green. 



Aug. 20. — Over a nest of Formica fttsca containing about 20 

 pupae I placed violet glass, purple glass, a weak solution of fueh- 

 sine (carmine), the same of chloride of copper (green), and of bi- 

 chromate of potash (yellow, not darker than saffron).

Here, again, in every case the pupae were brought under the

I then tried a nest of Lasiusflavus with the purple glass, violet 

 glass, the very weak bichromate of potash, and chloride of copper 

 as before.
