Having been engaged in an examination of the British species of Hemerohidce and allied families, preparatory to a Monograph of the species which T intend to work out in the same manner as that followed in the Trichoptera, I have been for some time aware of the existence in this country of three species omitted in Dr. Hagen's synopsis of the British species, published in the Entomologist's Annual for 1858 ; and I have thought it advisable to lay before those readers of this Magazine who attend to this subject, a short account of these three species, all of which we owe to the indefatigable researches of Mr. J. C. Dale. 1. — Sisyra Dalii, McLachlan. Semerohim nitididus, (Dale) "Walker, Brit. Mus. Cat. Neurop., pt. 2, p. 296, 61 ; nee. Fab. ; nee. Stephens.
