On the Heteromerous Coleoptera collected by Mr. W. Bonny in the Aruwimi Valley. By G. C. CHAMPION, F.Z.S. [Received November 13, 1890.] (Plate LVI.) The following is a list, with descriptions of new species, of the Heteromerous Coleoptera collected by Mr. Bonny at the Yambuya Camp. It forms a continuation of the paper contributed by Mr. Bates (ante, pp. 479-492), and has been undertaken at his request. Seventeen species only, representing the families Tene-brionidae, Lagriidae, and Meloidae, are contained in the collection ; of this number seven are described as new, and one new genus is added. Mr. Bates's remarks (op. cit. p. 480) as to the similarity of the fauna with that of the Cameroons and Old Calabar apply equally well to the Heteromera. Family TENEBRIONID_E. TARAXIDES, Waterh.
