Abstract
The gross anatomy of the central nervous system and retrocerebral complex of adult Liocoris unctuosus is described and figured. There are three ventral ganglia; the suboesophageal and first thoracic ganglia are separate, while the second and third thoracic are fused with the abdominal ganglia into a common center. Innervation of the reproductive organs in the male is described. The retrocerebral complex consists of the hypocerebral ganglion, paired corpora paracardiaca, and a single corpus allatum, and their associated nerves.
