Mother, You may observe that ciynex, 
the generic name, is placed as a title to

you have just read ; that name distin- 
guishes this species, and was applied to 
it from the circumstance of its living on 
stagnant water; cimex stagnorum signi- 
fying, literally, the bug of ponds or 
marshes. 
Lucy, Thank you, mamma; I under- 
stand this very well. I see that the spe- 
cific names are of the same kind of use 
as our Christian names.
