Abstract
1. The nervous system of femaleSaccharicoccus sacchari Cockerell is described in detail.
2. The nervous system of this mealybug is of a typical coccid type comprising a brain or supra-oesophageal ganglion and a thoracicoabdominal ganglion.
3. The brain lies anterodorsad to the oesophagus, while the thoracico-abdominal ganglion beneath the oesophagus.
4. The two ganglia are connected by a pair of circumoesophageal connectives which pass around the oesophagus.
5. The brain gives rise to three pairs of nerves which innervate the antennae, the ocelli and the mouth region.
6. The thoracicoabdominal ganglion gives rise six pairs of nerves, five of which innervate mainly the thoracic region and the last or sixth pair the abdominal region.
7. No ganglia or nerve representing a sympathetic nervous system were found.
