The small collection of CERATOPOGONINAE described in this note was made by me last December (1923) during a short voyage on the Nile from Cario to Assuan and back. The steamer on which the voyage was made anchored at night, and being brightly lit, attracted large numbers of midges which congregated on the woodwork in the neighbourhood of lamps and were thus easily secured. The collection, which was brought home to England before being examined, was not rich in CERATOPOGONINAE, but an account of such species as were contained in it may be of some interest, because little appears to be known about the occurrence of these midges in Egypt.
page 61 note * In all cases this measurement is taken from the anterior margin of the thorax to the tip of the abdomen of specimens mounted in pure carbolic acid.
page 66 note * Notwithstanding certain differences in the generic definitions, it appears that our Thysanognathus (Prionognathus) must be regarded as a synonym of Malloch's Neoceratopogon; for Mr. W. A. Hoffman, who has examined N. bellus, the type species of Malloch's genus, and has compared it with the description of our type species, has very kindly informed us that the two appear to be congeneric.
