The antennae of the sawyer beetles Monochamus notatus and M. scutellatus were examined with the light and scanning electron microscopes to determine the types, number, distribution and innervation of the sense organs. Nine types of sensilla are described. Both short, thin‐walled pegs (sensilla basiconica) and reversely curved thick‐walled hairs (sensilla trichodea) are chemoreceptors. There are three types of long, thick‐walled hairs (sensilla chaetica) which may be mechanoreceptors. One of these is modified in males to form unique snail‐shaped pegs. A few dome‐shaped organs, probably campaniform sensilla, were found. In addition to sense organs, many glands occur in association with the sensilla, and the antennae are well supplied with dermal glands connected by canals to small pores on the surface.
