STRANGE DWELLINGS . 
another gall afterwards. As a natural consequence, she has ! 
died from exhaustion before she could emerge into the air; 
and when I cut the double gall, in order to see how the inmates 
had fared, I found the dead insect lying near the middle of the 
second gall, so that she was even farther from the outer air than j 
when she started on her course. 
The Cynips Kollari is larger than the generality of the j 
family, equalling a small house-fly in dimensions. Its colour || 
is pale brown. A figure of the insect may be seen in the 
illustration. 
Nearly in the centre of the illustration is seen a figure of 
the well-known gall that is so common on the rose, whether j 
wild or cultivated, and which is popularly known by the name ! 
of Bedeguar. This gall is caused by a very tiny and very 
brilliantly-coloured insect, named Cynips roscz , which selects 
the tender twigs of roses, and deposits its eggs upon them. 
I have now before me quite a collection of these galls, some 
of which are so variable in shape that they scarcely seem to 
have been made by the same species of insect. When the 
Cynips rosae deposits her eggs upon the rose, the effects are I 
rather remarkable. Each egg becomes surrounded with its 
own cell or gall, and the whole of them become fused into one 
mass. The exterior of these galls is not smooth, like that of 1 
the specimens which have been described, but is covered with 
long, many-branched hairs, which stand out so thickly that they 
entirely conceal the form ot the gall itself. 
The number of galls in a single Bedeguar is mostly very 
great. A specimen of average size, taken at random from the i 
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
