One of the chief aims in drawing up descriptionptions is uniformity and what finally proved the most satisfactory method was to write out a straight-forward descriptionption, using contractions and starting each item on a fresh line, beginning at the head. Both supplementary to, and instead of this, various charts were tried and the one shown on Chart V was used for the present series. Such charts are not entirely satisfactory as the amount of detail needed to be recorded for any particular character varies from species to species, and different charts are needed for the various groups of Trypetidae.
