10. The Spinipedes, which have their 



thighs armed with fpines.

long and narrow body. 



Gecffroy obferves, that the antennas of the 

 Cirnices are compofed either of four or five arti- 

 culations (from which circumftances he has di- 

 vided them into two families) and that they are 

 longer than the head. 



The tarfi have five articulations. 



The larva? of the Cirnices run about, and, like 

 the compleac infect, fuck in their food through 

 their beak : many of them live upon the juices 

 of plants, others upon the blood of animals ; 

 feveral are found in the waters, and others fre- 

 quent houfes, among which is the common 

 Bed-Bug, an infect but too well known. They 

 differ from other infects in their foftnefs, and 

 rnoft of them emit a very foetid fmell. 



The common Bed Bug belongs to the family 

 of Apterous Cirnices. Scopoli, however, pre- 

 tends that it is likewife found with wings.
