MOTHER. In the genus of insects^ 
which I shall describe to-day, many spe- 
cies are familar to you : 1 have often 
heard you complain of their annoying 
buzz, and of the freedom with which 
they light upon your face. 
Lucy, I think, mamma, it must be 
of the common flies you mean to speak ? 
Mother, It is. In the genus ?nusca, 
or fly, there are above five hundred spe- 
cies ; but out of this great number I 
shall only select a few. The genus is 
distinguished by a soft, flexible proboscis, 
or trunk, with lateral lips at the end ; 
some have two short, simple antennae.
