Stephens, Manual of British Beetles, p. 61, speak-ing of Haliplus, says, antennae ten-jointed. Apparently all these writers had regarded the two basaljoints as one, the first division being considered the bulbof insertion, similar to that found in the Carabidae. Tlieinsects comprising the genus Haliplus have no bulb to thefirst joint (fig. 1, a and c), which is inserted into the headand moves freely in its socket (fig. 1, b), and joint 2, in turn,articulates on joint 1. For the purpose of comparison a 310 drawing is given of an antenna of a carab, Lehimorphabenefica, Newm. (fig. 1, d), showing the bulbous basal part.
