The paper describes sensory organs of mouth parts of various species of beetles of the genus Meligethes STEPHENS. Melighetes aeneus (F.) is a descriptive base. Four different types of sensory organs were found on the surface of mouth parts (sensilla trichoidea, s. campaniformia, s. chaetica and s. basiconica), with trichoid sensilla (s. trichoidea) functioning as chemoreceptors.
