Abstract

Analyses of the cockroach cuticle in different developmental stages and conditions give information on the changes taking place during hardening and on the differences between the pre-exuvial and post-exuvial parts of the cuticle. They give strong support to the conclusions reached from histochemical examination, and confirm the view that hardening of the cuticle involves a reduction in solubility of cuticular constituents as the result of phenolic tanning.
