The fat Histerid beetle was most amusing, getting out of breath every few feet, and abruptly stopping to rest, turning around in its tracks, standing almost on its head, and allowing the swarm of ants to run up over it and jump off. Then on it would go again, keeping up the terrific speed of two and a half inches a second for another yard.

We timed the laden Ecitons and found that they averaged two to two and three-quarter inches a second. So a given individual would complete the round in about two hours and a half. Many guests were plodding along with the ants, mostly staphylinids of which we secured five species, a brown histerid beetle, a tiny chalcid, and several Phorid flies, one of which was winged.
