THE LOCUST FAMILY.

The female lays her eggs in two rows in a sac 
which she fastens to her abdomen. She carries this 
about with her until the young are hatched. It is 
said that the mother roach broods her young but 
how this is known I am not prepared to state. 
The roach is very interesting from its great geo¬ 
graphical range; it is found wherever any insect is 
found. It is also interesting because of its ancient 
descent; fossil roaches having been found in rocks 
of the Carboniferous Age.
