BUG. 
Cimex per sonatas i of a black colour, a lengthened 
shape, and an unpleasant aspect: its larva how- 
ever is still much more so, appearing generally as 
if enveloped in a rough coating of grey dust, or 
fragments of down, &c. owing to the natural vis-

summer. 
Of the oblong-bodied Cimices the Cimex Hy~

beautiful insect: it is not uncommon on the plant 
Henbane, and is of a bright red and black colour, 
with brown wings. 
Among those with setaceous antennre of the 
length of the body is the Cimex Populi: its colour

colour, with a pale band across the upper part of 
the wings; and the tibiae or second joints of the 
hind-legs are expanded into a kind of leaf-like ap- 
pearance, and marked with white spots: it is a
