This second volume of colour plates features the remaining 328 plates of the series, or 2624 individual photographs to bring the total number of coloured illustrations of the series to 5036. It includes further illustrations of the families Anthribidae, Caridae, Rhynchitidae, Attelabidae, Brentidae and Apionidae of Orthoceri and of the Erirhinidae of Heteromorphi, but the bulk of the plates deals with the remaining subfamilies of the Gonatoceri. Two similar indices as in Volume V, but combined for both colour plate volumes, conclude Volume VI.
