112 SOCIAL HABITATIONS. 
the tiny branchlets with which they are studded, or of 
ramifying like the bough of a tree, as is often the case 
with them. 
The number of galls in a single Bedeguar is mostly 
very great. A specimen of average size, taken at random 
from the drawer in which the galls are kept, was, when 
fully clothed, as large as a golden pippin. When the 
hairy clothing was removed, its size notably diminished, 
and it was then seen to be composed of a large number 
of woody tubercles, varying much in size and shape. 
Their average dimensions, however, are about equal to 
those of an ordinary pea. The tubercles in question are 
fused together more or less strongly, some falling off at 
a slight touch, while others cannot be separated without 
the use of the knife. There are about thirty-five of these 
wooden knobs. 
On selecting one of the knobs, and examining it, a 
few very small circular holes are seen, showing that the 
insects have made their escape from the cells. Indeed, 
one or two of the insects were found entangled amid the 
dry and crisp hairs that surrounded the gall, and thus 
formed a second barrier, which they could not penetrate. 
When, however, a sharp knife is carefully used, the 
woody tubercle can be laid open in several directions, 
and then proves to be a congeries of cells fused together 
into one mass, and varying from four to twenty in 
number, according to the size of the insect. Per- 
haps, on an average, ten cells may be reckoned in each 
knob. 
In many of the cells the perfect insect may be found, 
the death of the rose-branch, and the consequent depri- 
vation of sap, having so hardened the walls of the cells 
that the inmates have been unable to make their way 
out. In other cells may be seen certain odd little objects,
