 ADDITIONS. 



1. Enallagma aspersiim 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. 



2. D oiywgomphus spoliatus Hagen. Old canal feeder along the St. Joseph 

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

 1901. Abundant; both sexes taken ; several exuviae gathered from piles at boat 

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

 insects: Pieris rapae, white cabbage butterfly, and the two dragonflies, Httaerina 

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



■No. I was published in last year's proceedings (1900), pp. 1V3-178.
