gether in small clusters, which only appears to 
common beholders like a roughness in the 
branches ; when, however, this is examined with 
the aid of a microscope, or even with the naked 
eye, the little hermit will be found concealed in 
the midst of it, quite inactive. It so remains 
through the winter. 
It evidently appears that torpidness is caused 
by cold, for I remember once, in severe weather, 
taking one of these animals into my hand, which 
was at first motionless, but in a few minutes, from 
the warmth, it became quite active. In the 
spring, when the sun becomes powerfully reviving, 
these little sluggards ai'e moved to quit their cells 
of solitary confinement, and soon appear on the 
leaves and bloom buds. They here commence 
their depredations. It does not appear that much 
injury is done by them fi’om the time they enter 
into existence to the time they become torpid, 
excepting that those leaves are a little ragged in 
the middle part, from whence they derive their 
support; but this cannot be so said of them on 
their revisiting the vernal buds at the spring, for 
they prove very injurious, by entering and feeding 
upon the interior part of the bloom and leaves, 
and thereby deprive the proprietor of a great por-

manner, and at the same time as the previous ones 
described. It is a very dark or snuff-coloured
