much as on previous occasions, and finally left high and 

 dry. But the rush was already lessening somewhat by 

 the time they were inserted, and a little later, when the 

 column had subsided to its normal dimensions or rather 

 less, it took very little notice of three more cofiee-bugs 

 and soon abandoned them completely, though a small 

 Elaterid was at once seized and hurried along to the 

 opposite drive. 



Meantime, the other party had established better 

 " through " communications once more, and though com- 

 paratively few in numbers seized and carried oiT into the 

 bank eight coffee-bugs, three weevils and a Harpactor 

 erythrocnemis (also taken in coffee), though still ignoring 

 to the same extent as previously the Amauris larva and 

 the fly. They attacked a small Mylahris amplectens, but 

 eventually abandoned it. 



Later, having captured a fine ^ A. areca, I returned the 

 Amauris larva and the fly to Column 2, where a large 

 number of ants were passing. Both were treated as 

 before. Two Epilachnas were attacked, but eventually 

 abandoned and gradually allowed to escape ; the original 

 Mylahris amplectens was still present, drawing an occasional 

 slight attack, but was mostly left alone ; a dead Dorylus 

 was ignored for a while, but then picked up by one ant 

 and carried along; the Acraea larva was attacked, but 

 allowed to escape. Afterwards, as it was moving along 

 parallel with the column, I was amused to watch it meet 

 a large number of ants. As each stopped and felt it with 

 its antennae the larva would stop dead. When the ant 

 moved on, as it invariably did at once, the larva would 

 move on too. There was no further attempt at an attack. 

 A small piece of banana pulp that I put down was attacked, 

 several ants making off to the drive with portions of it, 

 and an ordinary cattle tick {Rhipicephalus sp.) was seized 

 and carried to a drive, but not until it had inconvenienced 

 its carriers very greatly (three in all carried it, but only 

 one at a time) by getting under them and clinging to their 

 legs. A coffee-bug was seized and carried along. Then 

 A. areca, with wings shorn | of the way up and exuding 

 juice, was placed amongst them. Even in this condition 

 it was too active for them, so I killed and returned it, 

 when it speedily became a seething mass of ants. I put 

 down just afterwards an Amauris alhimaculata with its 

 wings attached and a cofEee-bug. The latter appeared
