STRANGE DWELLINGS . 
is one very large flake, that acts as a general roof to the 
structure. 
Within the nest are placed a number of cells made of the 
same material as the exterior, and in them maybe found insects 
in every state of development, eggs in one, larvae in another, 
and pupae in a third. No provision seems to be laid up within 
the nest, so that the inhabitants must depend on their daily 
excursions for their food. 
The insects are extremely small, barely one-fifth of an inch 
in length, and are reddish in colour. 
Perhaps one of the most terrible of insects is that which is 
appropriately called the Driver Ant of Western Africa 
{ A nominee arcens ) . 
This insect is a truly remarkable creature. Although it is to 
be found in vast numbers, it has never been found in the winged 
condition, and neither the male nor the female have as yet been 
discovered. The workers are uniform in colour, but exceedingly 
variable in size. Their hue is deep brownish black, and their 
length varies from half an inch to one line, so that the* largest 
workers nearly equal the common earwig, while the smallest are 
no larger than the familiar red ant of our gardens. In the 
British Museum are specimens of the workers, which form a 
regular gradation of size, from the largest to the smallest. 
They are called Driver Ants, because they drive before them 
every living creature. There is not an animal that can withstand 
the Driver Ants. In their march, they carry destruction before 
them, and every beast knows instinctively that it must not cross 
their track. They have been known to destroy even the agile 
monkey, when their swarming hosts had once made a lodgment 
on its body, and when they enter a pigstye, they soon kill the 
imprisoned inhabitants, whose tough hides cannot protect them 
from the teeth of the Driver Ants. Fowls they destroy in 
numbers, killing in a single night all the inhabitants of the hen- 
roost, and having destroyed them, have a curious method of 
devouring them.
