BRITISH WASP. 
Thorax with two yellow spots behind ; feet yellow, with 
the base of the thighs, and a spot on the four anterior 
tibia, black. 
This wasp, which is rare in England, is extremely com- 
mon in Scotland. In the spring the females build a small 
nest suspended from the eaves of houses, or attached to 
low bushes. The autumnal nests are found suspended 
from trees, especially from pines, varying from the size of 
a pear to that of a foot or more in diameter. In construct- 
ing these habitations, the materials are deposited on the 
outside ; and I suspect that these insects enlarge the nest 
by removing the internal layer with which they ae 
construct their cells. 
The nests are infested with a smal coleopterous insect 
named Lebia linearis. 
The annexed plate represents the spring nest—Fig. 1.
