In the Canadian Entomologist for December, 1894 (Vol. XXVI., page 329), I presented the species of Psychoda then known to me from Long Island, N. Y. In the following year, in the November number (Vol. XXVII., page 324, I added some notes and described one more species. Since then nothing has been published on our Eastern species. Prof. Kincaid, however, has been active in studying the Western species.
