five or six times and finally entered the true hole. The second 
went in and stayed a short time and then flew away. A new 
hole had been started under this false paper. Of the throngs of 
wasps (about 290 in five minutes) going into the true entrance 
almost all flew directly over the false to the true; occasionally 
one hovered a moment over the false. 
From 9:30 to 9:35 200 wasps entered the true hole, and two 
entered the false, one of these come immediately out and entered 
the true ; the other stayed in some time and then flew away. 
We now removed the false (blue) paper. One wasp came and 
hunted about in the grass where the blue paper had been and 
where a new hole had been started. 
After the yellow paper had been over the nest for three days 
we substituted, on August 18, one of a very slightly darker 
shade of yellow, moving the false hole to the south. Those 
counted below as deceived include three sets of wasps : those 
that hesitated over the true entrance and then went in without 
visiting the false ; those that went into the false entrance and 
those that only hovered over it before going to the true. 
From 2:50-2:55 p. m of 87 wasps 26 were deceived.
