1931 Two papers in one. 112 [34, 78] p., 47 text figures, paperbound (original printed covers). The first paper is by Edwards, the second, on Ceratopogonidae, by Ingram and Macfie who also made references to taxa from New zealand. Since the area studied was hardly explored before, both papers contain many new species and the second paper a few new genera (Edwards explained why he used very conservative genus-level systematics). A very good clean set.
