Five new species are described in the present paper. All of these represent extensions of the known range for the genus. All have nine-segmented antennae, two having a three-segmented club, one a four-segmented club, and wo 3 five-segmented club. The latter three, all of which occur in Sonora, are of particular interest, since they are the first species with more than three segments in the antennal club known to occur outside of Baja California.
