not the finely sculptured transverse striæ of that species, and the lateral tubercles are not pointed. The elytra are depressed, coarsely and sparsely punctured, with a raised flexuous dorsal costa; their colour is brassy green, especially visible on the base and sides, the middle of the back being tawny with an oblique dusky belt, sometimes absent. The antennæ are much longer than the body, but of the same form and proportions as in H. crista, the cilia only being longer; they are dull reddish, varied with dusky.
