The general plan of the arrangement of the muscles of the abdomen has been well established (Snodgrass 1935a). The system of nerves reaching these muscles should, it would seem logical, also exhibit a basic plan, if criteria of homology of nerves can be established. This study was undertaken to determine if such criteria exist in the limited field of the pregenital abdominal segments of some typical orthopterous insects. In the course of the work some details were discovered on the innervation of the ventral diaphragm which are included as a second section of this paper.
