Excerpt from The Olfactory Sense of Insects

Paasch (1873) claims that no nerves coming from the brain lead to the trachea and that the Olfactory organ need not necessarily be connected with the breathing apparatus. He reasons that its location should correspond with that found in higher animals. He found a peculiar plate situated between the eyes and beneath the antenna and extending to the base of the proboscis. This plate possesses a groove whose edges are beset with stiff bristles, and many tracheal branches; it also has nerve connections. This he regards as the Olfactory organ. This plate does not exist in the honey bee.
