This is the start of an experimental Dichotomous Key for Coleoptera (Beetles) based on the key in the textbook Study of Insects by Borror and DeLong (seventh edition).  There is a webpage for each couplet in the key.  Three options are given:  Return to Previous Couplet, Go to Couplet X, Go to Couplet Y.
