On a new species of the Longicorn genus Zonopterus, Hope

This species, of which I have three female specimens before me, is most nearly allied to and strongly resembles the type of the genus: Zonopterus flavitarsis Hope 1). It is of the same size and general form, but the sides of the prothorax, which are distinctly bisinuate in flavitarsis, are more regularly rounded in the new species. The latter has moreover a narrower scutellum which is hollowed along the middle and has raised sides, whereas the sculpture by which it is covered is much less dense, even almost absent at the base. The femora, which are coarsely punctured in flavitarsis, have a much finer punctuation in the new species. But besides by these structural characteristics the two species may be at once separated by the different distribution of the colours on the antennae: in flavitarsis the four basal joints and a spot at the base of the fifth, in the new species, however, the six basal joints are black. Moreover the first yellow band of the elytra is decidedly narrower in the new species than in flavitarsis.
