In this paper we first describe two new species of Fridericia from Urbana, Illinois. The major part of these descriptions was contained in a thesis offered by the junior author in 1911 in partial fulfillment of the requirements for the master's degree from the University of Illinois. We next extend the description of Fridericia agilis Smith and add a number of rather important characters not previously given. Finally, we describe a new species of Marionina from Urbana, Illinois, which is the first member of this genus reported from the United States.
