Ophrygonius singapurae, u. sp. Text-fig. 3B. Described from a single specimen from Singapore in the collection of the Konigliches Zoologisches Museum in Berlin. Description.—Length 31 mm. This interesting species is closely allied to the preceding, with whose characters it combines some of those of Ophrygonius inacqua- lis on the one hand, and of Aceraius wallacei on the other. The lamellae of the antennae are all very long and slender as in A. wxllacei. The lowest terminal tooth of the is probably well-developed on both sides in fresh specimens, as is usual in this genus; but that of the right side is very obtuse (probably through friction) in the specimen before me; the anterior lower tooth of both mandibles is very broad, and flattened dorso-ventrally, resembling that of the left mandible of most species of Aceraius, though the horizonal margin is scarcely grooved. The mentum resembles that of Ophrygonius inaequalis. The head bears distinct, finely keeled, frontal ridges (not grooves) as in 0. inaequalis; the left outer tubercle is intermediate in form between that of 0. cantori and 0. birmanicus ; the parietal ridges are somewhat short; the supra-occipital ridge is united to the supraorbital.
