Corn is given as one of the plants infested as it is so recorded 
by Prof. Forbes^ and specimens were received here from Mr. 
Jabez Bower^°, of Norwa}^ Iowa. We have not found them on 
corn in this locality.

NOTES ON SYNONOMY. 
In the 13th report of the entomologist of Illinois, Forbes 
gives Schizoneura venusta as probably identical with Schizoneura

^ The winged forms have not been obtained from these plants, but the apterous 
forms on Panicum virgatum and Timothy seem to agree with the corni, and those on 
annual plants with panicola.
