Notes on Ant Behavior 211 
these ants. The leaves were treated in such a way as to com- 
pletely hide and protect the aphids.

I had read of slave raids but had never witnessed one, so 
I was delighted to see the process going on in my backyard. 
On Saturday, July 29, 1932, a member of the family saw a 
large number of ants very busy in the drive-way and as their 
activity continued through to the next day my attention was 
called to them. They probably worked all night for at 7 a. m 
I found them still active. The red ants, the slave makers, 
Fornuca sanguinea sub-sp. subintegra Emery, were moving in 
two more or less haphazard single files, one in each direction. 
Those going north were empty handed but each ant going south 
carried a black ant; some of the black ants were alive and 
struggling fiercely and others were dead. They were moving 
over a cement walk for some distance and then over grass, sticks 
and pebbles, finally gr aie in a crack in the earth under 
the walk some forty feet away. 
This raid was carried on, on a large scale for about one and 
one-half hours that morning, and then the participants dwindled 
in number so that by a. m. no more were seen. any of 
th 
examined both Liga e for identification, gee be the slaves 
were infected, as have been other species of ants taken in my 
yard, with the parent fungus, Laboulbenia Pettey 
Formica pallide-fulva var. nitidiventris 
(Emery) [M. R. ee 
About six weeks after an empty soap-box was placed on 
the bare ground in an open shed, ( Ceatemie 15, 1931), a thriv- 
ing colony of ants of this species was found nesting in the 
ground under the box. The ants were very active on top of 
the nest during the night. I often amused myself by watching 
them carry into the nest bits of raw beef and granules of sugar 
which I placed on the ground. But of most interest were the 
beetle, orthoptera and lepidoptera guests that were found at the 
opening of the nest when I lifted the box. On September 15, 
ten caddice-like worms protruded from the rounded neck of 
their houses (two of them however were completely sealed and 
were probably in pupal stage). The cases were made of mud 
by the larvae of the little é hrysomeled beetle, identified by Dr 
Wm. M. Wheeler as Coscinoptera dominicana, ese ten were 
taken and the next day at 8 a. m. two more, and finally at 
7:30 p. m. three additional ones were taken at the opening.
