Volume V features the first 304 of the total 632 colour plates of the series, each consisting of 8 photographs and generally illustrating 4 species in dorsal and lateral aspects, respectively. It covers all the primitive families (Orthoceri) from Anthribidae to Apionidae, as well as the Heteromorphi and the subfamilies Amycterinae and Entiminae (Adelognatha) of the Gonatoceri. Two taxonomic indices, one by genus to species and the other by species to genus, conclude the volume.
