On the Anatomy of Grylloblatta Campodeiformis Walker. 1. Exoskeleton and Musculature of the Head.

Abstract

This is the first of a series of papers on the anatomy of the primitive Orthopteran Grylloblatta campodeiformis Walk., which it is hoped may be ready for publication from time to time within the next few years. The present contribution deals with Grylloblatta only, comparisons with other Orthopteroid insects being reserved for the next paper of the series.
