Description The thorax is slightly longer than in the similar species Downesia atrata, with the sides straight, obsoletely sinuate, nearly parallel and only slightly converging from the base to within a short distance of the apex, where they suddenly converge to the apex itself. The apical margin is slightly produced. The upper surface is finely and subremotely punctured. The elytra are sculptured as in Downesia atrata.Descriptions of New Genera and Species of Hispidae; with notes on some previously described species
