Ulomoides dermestoides （Chevrolat）（Coleop- tera： Tenebrionidae） is one of the most notorious pests in northeastern China. We examined microtrichia on the thorax, elytra and abdomen of U. dermestoides using scanning electron microscopy and recorded their confor- mations （size, shape and insertion method） and distribu- tions （length, width and location）. Possible functions of the microtrichia were （1） stridulation： microtrichia on the inner surface of the elytra interacted with microtrichia on the dorsoventral axis of the thorax or on the costal vein of the hind wing; （2） to increase friction： at the major surface on the middle of the abdominal tergum, hind-wings, inner surface of the medial edge of the elytra and the posterior end of the elytra; （3） protection： the microtrichia covering the posterior face of the abdomen conserved water in the body and protected the body from damage; and （4） sensing organ： the special shape of the microtrichia on the nerva- tion near the vannal fold of the hind wing, the anterio- metapleuron on the metathorax, and the posterior field of the abdomen could perceive the environment. In conclusion, the size and shape of the microtrichia are tightly related to their functions, which may have evolved with the beetles＇ lifestyle.

The first synopsis of Mesozoic weevils （Curculionoidea： coleoptera） is pre- sented. Changes of family, genera and species abundance during the Mesozoic revealed three distributional patterns. The Jurassic （Karatau） fauna was dominated by the Nemony- chidae. During the Early Cretaceous （beginning at the Jurassic/Cretaceous border）, the Ithyceridae was the prevalent group with a significant role played by the Nemonychidae. In the Late Cretaceous （Cenomanian and Turonian）, the major groups were the Curculion- idae and Brentidae. Obviously, the change of weevil fauna during this period was due to the expansion of the angiosperms, which provided multiple niches in their vegetative and reproductive organs for weevil development.

The present paper is devoted to an overview on fossil coleoptera studied from Inner Mongolia, Daohugou （Middle Jurassic, Jiulongshan Formation） and Liaoning （Upper Jurassic-Lower Cretaceous, Yixian Formation） deposited in Chinese collections. As a result, species of the tribe Sperchopsini and Hydrophilini from Hydrophilidae, families and subfamilies Silphidae, Syndesinae from Lucanidae, Pleocomidae, Trogidae, Trogissitidae, Pyrochroidae, Diaperinae from Tenebrionidae, and Cerambycidae were first registered in the Mesozoic and some families were defined as new. It was shown that many superfamilies represented in the Recent Fauna were formed within the Middle Jurassic and Lower Cretaceous. The materials examined confirm the hypothesis that Cucujiformian beetles are a younger group than other infraordera of Polyphaga （Staphyliniformia and Elateriformia） and, therefore, they appeared in the fossil record only in the late Mesozoic. It was shown and confirmed that most superfamilies appeared in the fossil records before Cucujoidea. The synonymy of Notocupes Ponomarenko, 1964; Sinocupes Lin, 1976, syn. nov.; Amblomma Tan, Ren et Liu 2005, syn. nov.; Euryomma Tan, Ren et Shih, 2006, syn. nov., non Stein, 1899 and Ovatocupes Tan et Ren, 2006, syn. nov.; synonymy of Tetraphalerus Waterhouse, 1901 and Odontomma Tan, Ren et Ge 2006, syn. nov.; and synonymy of Priacmopsis Ponomarenko, 1966 and Latocupes Tan et Ren, 2006, syn. nov. are proposed. Sinorhombocoleus papposus Tan et Ren, 2009 is transferred from the family Rhombocoleidae to Schizophoridae. Cervicatinius complanus Tan, Ren et Shih, 2007 and Forticatinius elegans Tan, Ren et Shih, 2007 are transferred from the family Catiniidae （suborder Archostemata） to superfamily Cleroidea （suborder Polyphaga： first among the family Peltidae and second as a closely related group to the latter family）. The family Parandrexidae is transferred from the superfamily Cucujoidea to Cleroidea. The ecological circumstances of the past ecosyst

Adults of the aquatic coptoclavid beetles （coleoptera： Adephaga： Dytiscoidea）, described from four Middle Jurassic fossil localities in Inner Mongolia and Liaoning in northeastern China, are attributed to Daohugounectes primitives Wang, Ponomarenko and Zhang, 2009, which was previously proposed after study of larvae. The generic name Timarchopsis Brauer, Redtenbacber and Ganglbauer, 1889 is proposed as a substitute for the preoccupied and junior homonym Necronectes Ponomarenko, 1977, non Milne-Edwards, 1881. Furthermore, the subfamily name Necronectinae Ponomarenko, 1977 is substituted by the available name Timarchopsinae. Daohugounectes is placed into Timarchopsinae because its adults have long, slightly apically widened tibiae and small femoral plates. The adults of this genus differ from those of other Timarchopsinae in the following features： antennae short and widened in the middle part; basal segments of protarsi not cut apically; metaventrite with a triangular plate. The larvae look like somewhat primitive forms in the subfamily Timarchopsinae. In contrast to these primitive larvae, the adults with some advanced characters can be regarded as among the most advanced forms in the subfamily Timarchopsinae, and probably represent a transition between the Timarchopsinae and Charanoscaphinae. Such mosaic evolution within Daohugounectes indicates that the evolutionary process of aquatic beetles is far more complex than previously thought.

Fossil water scavenger beetles （coleoptera： Hydrophilidae） of the latest Oligocene Rott Formation are revised, based on the examination of the type specimens, as well as numerous additional material from Statz （Los Angeles） and Kastenholz （Bonn） collections. Seven hydrophilid species are recognized, five of which are reliably attributed to the following genera： Berosus morticinus （von Heyden and von Heyden, 1866）, Paracymus excitatus （von Heyden and yon Heyden, 1866）, Paracymus sp., Hydrobiomorpha fraterna （von Heyden, 1859）, and Hydrophilus rottensis （Statz, 1939）. Coccinella？protogaeae Germar 1837 is attributed to the subtribe Hydrophilina, and Cymbiodyta？ austera Statz 1939 to the subfamily Hydrophilinae. Hydrous ebeninus Statz 1939 and Paracymus excitatus （form 3） are excluded from the Hydrophlloidea. Berosus capitatus Statz 1939 is synonymized with Berosus morticinus, and Hydrous neptunus von Heyden and von Heyden 1866 with Hydrobiomorphafraterna. Lectotypes of Philydrus morticinus von Heyden and von Heyden 1866 and Hydrous ebeninus Statz 1939 are designated. The significance of the hydrophllid fossils for paleoecological reconstructions of the former Rott Lake is briefly discussed.

Two new species of the genus Eumyllocerus Sharp, 1896, of the subfamily Entiminae Schoenherr, 1823, are described from China. Eumyllocerus longisetus sp. n. may be distinguished from other species of the genus by its long bristle-like, erect setae on the intervals, each of which is longer than the width of the second interval, the setae arrangedin double rows, and its shell-like, shiny, dense, metallic green scales. Eumyllocerus rotundicorpus sp. n. may be distinguished from any other Eumyllocerus species by its oval and inflated elytral shape, short stout metepisternum, small humeri, elytral setae shorter than 0.5 times the width of the second interval, the setae arranged in double rows, and its golden copper and pearl gray scales. The taxonomy of the genus is discussed. The two new species are described and habitus photographs and figures of diagnostic characters are provided. The type specimens of the new species are deposited in the Institute of Zoology, Chinese Academy of Sciences, Beijing, China (holotype and paratypes) and the Korean Entomological Institute, Korea University, Seoul, Korea (paratypes).
