 ADDITIONS. 



1. Enallagma aspersion Hagen. A single female was taken June 27, 1901, in 

 the woods on Chapman Hill, near Winona Lake. The female of this species of 

 Enallagma is so distinctively colored that I do not hesitate to record the species 

 for the State on such scanty material. I think this species will be found to be 

 extremely local in di-tribution.

 River, and St. Joseph River, Robison Park, Ft. Wayne, July 19 and August 11,

 landings in Robi-on Park; observed feeding on adult imagoes of the following

 americana and Argia putrida. An active, inquisitive species, relentless in love
