In. Insects the brain consists of a number of swellings, all Of which are paired; the foremost pair are the lobes from which the antennas spring - these are equivalent to the lobi olfactorii of vertebrates; the next pair are the main cerebral ganglia, from which the Optic lobes can separate as special lobes. The oesophageal commissures are the crura cerebri, and, the infra-oesophageal ganglia correspond to the cerebellum and medulla Oblongata, from which arise the nerves for the mouth parts.
