Habitat: East India.
General colour dark brown, almost black. Thorax smooth and shining, as if polished, and terminating in a strong thick horn, which inclines forward in a curved position, and is forked at the end. From the head also springs another strong horn, forked at the extremity, which in length corresponds with the first; its outer side being broad and round, but its inner side, or that opposite the other horn, is thin and sharp, having a small swelling in the middle. Elytra smooth and shining, with a narrow margin. Anterior tibiæ with four teeth; two being at the tip, and two a little above them. The other tibiæ are furnished with several sharp spines (five or six), chiefly about the tips; which, as noticed in D. Titanus, assist the animal in its passage. Anus not hairy, as in many other species.
