3. The predaceous habits of D. nigricans.—An extract from 
Mr. Lamborn’s letter, dated Nov. 1, speaks of “ disaster from 
a totally unconsidered source which swept away in a night 
15 or 20 pupae of the P. cardwi family, about 10 pupae from 
wild cardui larvae and 7 or 8 of the Satyrid pupae. I 
awoke one morning to find these all gone without leaving any 
traces. Ultimately I found two major and one minor driver 
ants in a test-tube of water left in one of the boxes; so the 
ants had raided my dining-room during the night and evacuated 
the position by morning while I was comfortably asleep, as 
usual, in my camp-bed out on the verandah. I don’t think 
I mentioned that they came in one day last week at 7 a.m. 
and cleared the house of all other insects, including Pheidole 
and the small red ant Monomorium pharaonis, L., and they 
even caught two unfortunate bats in the eaves, one of which 
was killed, but I managed to free and let loose the second. 
On this occasion I repulsed the drivers with very heavy losses, 
but this does not seem to have been a lesson to them. Much 
to the disgust of my boy I always put most of my boxes on 
the table for the night so that, as the ants did not get up the 
rounded polished legs, my loss is not so bad as it might have 
been, and the dardanus family did not suffer.”’ 
4. Camponotus sericeus attacking Dorylus nigricans on the 
march.—The following note referred to the specimens exhibited 
to the meeting, viz. two workers of Camponotus sericeus, F., 
one of them with a worker minor of Dorylus mgricans, Illig., 
fixed to its leg. 
‘“ Tsend two ants, one with a ‘ driver,’ soldier minor, gripping 
its 2nd right tibia. The history of the specimens is as follows :— 
On June 12, 1913, at 2 p.m., after heavy rain, a column of 
drivers was observed on the march along a channel between 
two earthworks which they had thrown up across the path. 
On the top of the earthwork were the two ants, evidently bent 
on mischief of some kind. They leaned over, narrowly 
examining the column of drivers and every now and again 
seized a minor which was released after a short scuffle. When 
a major came with open jaws to reinforce the minors, these 
ants did not retire but anteflexed the abdomen so that its 
point was presented between the fore-legs. The major then
