280 HYMENOPTEUA 



at a distance by surrounding itself with bubbles of foam 

 into which the ants could not penetrate. 



A medium sized Plant bug (Hemiptera) was once seen 

 on a leaf of a bush over which Dorylus was swarming, 

 and I was much interested to note that although ants 

 would frequently seize hold of a limb or antenna of the 

 bug they always let go again, and no harm was done to 

 the bug. It is possible that its powerful odour may 

 have been disagreeable to the ants. 



One night a large army of Ensanafu raided my grass 

 hut on Bugalla Isle ; fortunately I was sleeping in a 

 tent close by, and though a column ran through the 

 tent they were only on the way to the hut, and I was 

 not turned out. But a nestful of fledgling swallows in 

 one corner of the hut was cut up and carried away piece-

One day at Jinja I heard pitiful squeakings coming 

 from some long grass, and found a baby striped rat being 

 attacked and in danger of a horrible fate ; needless to 

 say he was freed, but very likely fell a victim subsequently. 



During the campaign in German East Africa I was 

 twice turned out of the little tent in which I was sleeping 

 on the ground by an invasion of Ensanafu, and had to 

 bolt, and then, after picking off those ants which had 

 already attached themselves to various parts of my 

 person, make a dash for boots, and by frequent painful 

 visits gradually withdraw the bedding and shake down 

 elsewhere outside, while the ants proceeded along the 

 line to some one else's tent, to my secret gratification, 

 for no one likes to be the only one who is turned out in 

 the night ! 



On Damba Isle in July 1911, I saw a very interesting 

 thing while watching the unfortunate denizens of the 

 shady forest being turned out by Dorylus. Cockroaches 

 were scurrying about in all directions, and hovering 

 over them, and occasionally darting down upon them,
