The resemblance of this species to H. convergens, and especially the simi- larity of their larvae, is such that it has probably been derived from that older type at no very distant date. The pronotal pattern is like that of H. convergens, but shows relatively less variation (fig. 9). Var. A. The humeral spot absent.
