As the fifth volume in F.N. Pierce's series on the Genitalia of the British Lepidoptera, "Pyrales, Deltoids and Plumes" was published in 1938. Though they are regarded as invaluable for identifying difficult species, the originals are not easily available, and the reprinted versions were considered inferior in quality.
The publishers have worked with the Lancashire and Cheshire Entomological Society to produce this volume in electronic form. The quality of reproduction of illustrations and text is excellent.
