Thus, the effect of food on the rate of ovisposition and also on the length of 
life is plainly indicated, but from the fact that but two individuals were 
used, nothing conclusive can be drawn. 
It would also seem to indicate that but one principal brood occurs through 
the season, or that the females continue to lay at periods during the main breed- 
ing season, as in the case of Anasa tristis. It may be noted that these females 
when captured had already deposited some of their eggs. 
2. Length of life in confinement with and without food. 
It is often mentioned that these insects can survive for months wdthout 
known food. This has been established by confining single specimens in closed 
vials or boxes, and leaving them undisturbed. W’riters disagree on this subject, 
and extended breeding experiments are necessary before it can be definitely 
settled. 
But few observations were made bearing on this, but it may be well to put 
them on record in this connection. A fully fed female, confined after capture, in 
a closed pill-box, lived twenty-four (24) days without food, during June and
