PLATE X. 
Nest of V. rufa, turned upside down so as to display the 
entrance. The edges of the frills with which the surface 
is covered are plainly shown. The nest is spherical and 
of the same size as the drawing. p. 214. 
PLATE XI (facing the Title). 
Oval nest of V. britannica, from a pear-tree. The thickness 
of the case, the free irregular way in which the sheets of 
paper overlap and are connected to each other, and the 
loose ragged edges are characteristic of the architecture 
of this species. The entrance hole is represented, as 
usual, rather to one side. The little horn or porch often 
found surrounding the entrance was absent in this speci- 
men. About three-fourths of the natural diameter.
