Genus III. — ’Terrnes. 
The difcriminating charafters of thefe infers are drawn 
from the mouth, which is armed with two jaws ; from 
the fetaceous antenn®, and the fix feet, which are formed 
for walking f. 
There are only three fpecies of thefe fmall in feels ; to 
one of which linnetus has given the name of Pulfatoria, 
from its being fuppofed to imitate the tiding of a watch, 
by finking its head again!! the wainfcot in the dead of 
night. This noife, fo alarming to fome fuperftitious 
minds, has been called the death watch, and is probably 
occafioned by the plinus one of the coleopterous infeds. 
The terines pulfatorius varies in its colour according 
to its refidence : When met with in houfes, it is com- 
monly of a whitilk colour ; if found in the fields, as is 
fometimes the cafe, it tends more to a orown comur, and 
is fomewhat hairy J.
