164 UUG. 



have never observed in any other creature: in 

 these too, if clear, as they may sometimes be 

 found, the wonderful motions of all the internal 

 parts will afford an agreeable entertainment to 

 the curious, and may be examined as long and as 

 often as they please; for I have kept a Bug alive 

 in a slider between two pieces of isinglass at least 

 six weeks together, notwithstanding it was con- 

 fined so close as to be uncapable of stirring; and 

 although during that time it often seemed dead 

 and motionless when I placed it before the micro- 

 scope, a little warmth would set the bowels in 

 motion, and renew the current of the blood as 

 briskly as ever." 



A variety of this Insect is sometimes seen, 

 which is generally known by the name of the 

 American Bug ; it is of a longer shape than the 

 common species. 



So very numerous is the genus Cimex, that it is 

 found necessary to divide it into several sections, 

 according to the general shape or habit of the In- 

 sects. Among those in which the scutellum or 

 triangular part between the setting on of the 

 wings is of equal length with the body the 

 Cimex lineatus may serve as an example, which is 

 of a black colour, varied with yellow, having five 

 yellow lines down the thorax, and three on the 

 scutellum, and the abdomen yellow with black 

 spots. It is a native of Barbary and some of the 

 Southern parts of Europe. 



Of those in which the upper wings are of a 

 much more strong or coriaceous nature than the
