Prof. ('. K. I'x'ssey puhlished a preliminary list of tlie 

 Ovthoptcra of Iowa in 1S77.' Mr. .1. Duncan Putnam pub-

P^ntomoloaically we occupy interesting- territory, since in 

 our fauna we ha\-e a miniiiiui;- not of eastern with western

 here. Moreover, we have fr<'(pient evidence of the i)artial 

 innovation of souihern f(»rms — species which, a[)parently, 

 reachiuii us as straii<rlers are able some seasons to fi.\ theni-
