Neuropile is stippled; regions of ganglion cells are unstippled. 90 X. reported that the prothoracic ganglion of Nepa is divided into a dorsal lobe, with loose neuropile, and a ventral, glomerular lobe. No such division was observed, however, in the prothoracic gang- lion of Gelastocoris. The two longitudinal connectives between the prothoracic and posterior ganglia are entirely separate. They are long and broad, and are flattened for most of their length. The posterior ganglion is very large, and its neuropile is divided into three main regions, representing the fused mesothoracic, metathoracic, and abdominal ganglia (Fig. 22). In the anterior and middle parts of the posterior ganglion lie the lobes of the mesothoracic.
