Abstract
This is an experiment in a graphical layout for the preparation of field keys, combined with the use of "spot" characters for rapid identification. It is intended to get over the chief snag of dichotomous and punched-card keys, for both of which the compiler and user need to know a great deal about each specimen; information which for seasonal reasons may be lacking. The present work is designed both as a memory stimulator for those who already know some of the species and as an aid to identification for those new to them.
