In literature references to the larvae, I (continued next page) chose a monophyletic group (a group that includes a common ancestor and all its descendents) within Limacodidae to em­ phasize in my dissertation.

The same pro­ cess will also be carried out on genera outside the monophyletic group.

a long and continuing tradition. It may also help non-entomologists understand why insects are worth so much time and effort. Evans closes with some interesting thoughts on the importance of amateurs in entomology: "The most serious dichotomy is that between the professional entomologist and the layman who thinks of insects (if he thinks of them at all) as something unworthy of more than a swat or a squirt. Entomology was born among lay­ men, among amateurs such as Kirby, Spence, Darwin, Wallace, Fabre, Melshei­ mer. It passed to the hands of people only marginally employed in entomology, figures such as Say, Peck, Harris, and Cockerell. Just a few decades ago, it was not unusual for amateurs to attend meetings of many of our entomological (from previous page) societies, but few still do.
