Antennae basally somewhat dilated and slightly compressed, about half as long again as the head. Head conical, as long as pronotum. Face very strongly oblique, obsoletely punctured and with irregular subobliterate longitudinal rugosities. Frontal ridge between antennae raised, below ocellum very low, with the sulcus distinct throughout, widened at the fastigium ; margins very obtuse. Eyes strongly elongate. Fastigium of vertex (fig. 4) about as long as an eye, and about half as long again as the basal width ; its sides, seen from above, distinctly concave ; surface convex, with a faint trace of the median carinula in the hind part, the carinula being better developed on the occiput.
