The short esophagus leads obliquely dorsad into the crop which is located in the head immediately posterior from the brain and extending posteriorly to the beginning of the first thoracic segment. The crop is irregularly rectangular in form with a chitinous framework well-armed with teeth and stiff setae. (Fig. 1). It is divided into two parts, the cardiac and the pyloric. The cardiac division is smaller than the pyloric, being slightly shorter and a little more than one-half as wide.
