On a new Genus of Heteromerous Coleoptera. 147 tralian coast may be mentioned Micippoides longimanus, mihi, Schizophrys aspera, White, Cyclomaia margaritata, Stimpson, Hyastenus oryx, A. Milne-Edwards, Micippa parvirostris, Miers, M. spafulifrons, A. Milne-Edwards, M. superciliosa and M. inermis, mihi, and Paramicippa spinosa, Stimpson. Among the Periceridae the only genus represented is Tia-rinia, of which there occur three species, all confined to the tropics. The family Parthenopidas, on the other hand, is very abun-dant in genera and species, by far the greater number of which are confined (so far, at least, as at present known) to tropical seas. Of the genus Lambrus (including Parthenope), there are no fewer than nine species ; these are : — L. longi-manus, Milne-Edwards ; L. turriger, L. hoplonotus, L. harpax, and L. calappoides, Adams and White ; L. nodosus, Lucas ; L. affinis, A. Milne-Edwards ; L. spinifer and L. Sandrockii, mihi. There are two species of Cryptopodia (C. fornicata, Fabr., and C. spatulifrons, Miers), one of Zebrida (Z. longi-spina, mihi), two of Gonatonotus (G. pentagonus, Adams and White, and G. crassimanus, mihi), and one of Harrovia (H. tuberculata, mihi). Sydney, Dec. 3, 1879. XIII. — Description of a neio Genus and Species of Hetero-merous Coleoptera. By Charles O. Waterhouse. On two or three occasions I have had brought to me for de-termination a small heteromerous beetle which appears to be always associated with grain of some kind, especially rice. The species appears to be not uncommon ; but I have been unable to find any description of it. Specimens of the species have been in the British-Museum collection for many years, but without any name ; and 1 have been unwilling to describe it, from the fact of its being widely distributed and therefore likely to have been in the hands of continental authors. Having again made an unsuccessful attempt to determine it, and being informed by Mr. F. Bates that he has it in his col-lection noted as a new genus, I now venture to name it as follows : — Ulomidae. Latiieticus, n. gen. General form of Tribolium. Mentum transverse, the an-terior angles rounded, the front margin gently emarginate in the middle, the ligula not much projecting, transverse, emar-
