having attained its full complement of limbs, and ac- 
quired its moll perfect form, the cockroach difplays a 
mouth armed with jaws, and furniflied with palpi. Its 
antennae are generally as long as the body, and the abdo- 
men as broad as the thorax. The tarfi of the tore feet 
have five joints ; thofe of the hinder only four; while the 
horns which terminate the abdomen are furrowed, or 
Wrinkled tranfverfely *. There are ten fpecies of this 
genus, named, for the moll part, after the different coun- 
tries which they inhabit.
