It is further reported from Ohio, Iowa, Kansas, and Missouri toKentucky, Arkansas, and Oklahoma. Consistently with the relatively large size of this species, larva;and pupa? of May-flies were found by us to predominate in its food,including one of the largest larvas of this family (Hexagenia) in ourstreams. Larvae of dragon-flies, a small percentage of Chironomuslarvae, and water-bugs (Corixa), were the other elements of its food. Females greatly distended with eggs were taken by us June5, 1901.
