l66 BUG. 



Cimex personatus, 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- 

 cidity of its body and limbs, and its frequenting

 bug, and is of a much larger size, and of a more 

 disagreeable aspect. The complete insect flies 

 only by night, and appears towards the decline of 

 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 antennas of the 

 length of the body is the Cimex Populi: its colour 

 is a clouded variegation of black, brown, and

Of those with spiny legs, one of the most re- 

 markable is the Cimex phyllopus. It is of a blackish 

 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
