cell, and eleven examples found in another, by Mr. C. O. 
Farquharson, B.Sc., at Moor Plantation, near Ibadan, S. 
Nigeria. The history of the discovery was given in the 
following extract from a letter written, Sept. 23, 1913, by 
Mr. C. O. Farquharson to Mr. Lamborn. The beetles had 
been kindly named by Mr. K. G. Blair, F.E.S. 
“The two small clay cells which I brought you the other 
night were found (Sept. 19, 1913) on an old stump by the side 
of one of the streams in the plantation. On collecting the 
first one, the base was somewhat damaged and I was surprised 
to find the interior nicely filled with a collection of small 
beetles. The second cell I collected unbroken, and as I found 
the opening loosely blocked I thought perhaps it might contain 
a Hymenopteron of some sort. As you know it also contained 
small beetles, similar to the other.” 
[Prof. Poulton, in exhibiting the specimens, suggested that 
the beetles had been stored by an Aculeate; but a later 
letter from Mr. Lamborn, dated Dec. 3, 1913, stated that the 
beetles ‘‘ had obviously congregated of their own accord, for 
both the clay cells were open and the beetles in one were so 
lively that Mr. Farquharson had to plug the hole to keep 
them in during the walk home.”’] 
Mr. W. A. LAMBORN’S OBSERVATIONS ON THE DRIVER ANTS 
(DoryLus) oF SouTHERN NicEr1aA.—Prof. PouLton read the 
following notes received from Mr. Lamborn and exhibited the 
material referred to. The ants had been kindly determined 
by Mr. G. Meade-Waldo and the Diptera by Mr. E. E. Austen. 
1. Dorylus helvolus, L. (Typhlopone punctata, Sm.).—A series 
of workers of various sizes. “* These reddish ants appeared to 
be engaged, some in bolting earthworms from their burrows, 
‘others in killing the smaller ones, cutting them into sections, 
and carrying them off.” Aug. 10,1913: Agege, about 12 miles 
N. of Lagos. 
2. Dorylus nigricans, Ilig—Two long series of workers of 
various sizes, one accompanied by the note: “ These ants 
were marching in column at Agege after rain on August 20,” 
the other captured, Oct. 12, at Moor Plantation, near Ibadan. 
The following notes refer to this species of Dorylws, and record 
observations made at Moor Plantation in 1913.
