NOTES ON THE ORTHOPTEROUS FAUNA OP IOWA. 
BY E. D. BALL. 
As a family the Orthoptera have long been regarded as 
among the most iDjurious insects of the state. Every addition, 
therefore, to a list of species adds one more to the number of 
possible depredators of a given locality. On the other hand, 
every fact in regard to distribution, life-history or food habits 
of a species, added to the general knowledge, aids in formulat- 
ing successful methods of treatment for the particular species.
