from denticulata by the smooth, not sinuate, elytral apices and by the presence of more than one piceous abdominal segment;
from californica by the lack of all piceous abdomen and by the shallower punctuation on the under surface, especially on the metasternum;
by the gradual, not abrupt, emergence of the antennal club from the stem, by the lack of all piceous abdomen, and by smaller size.(1)
