New state record and range extension for Mycterus youngi Pollock (Coleoptera: Mycteridae) – but is it really rare?

Mycterus youngi was described from Wisconsin and “L.S” (presumed to indicate along Lake Superior). All but one of the specimens in the type series were collected between 1947 and 1949. Herein, three females of M. youngi are reported from Michigan, between 1910 and 1940. A discussion of possible implications of the few, and largely old collection dates is provided

A strongly coupled anyon material

We use alternative quantisation of the D3-D5 system to explore properties of a strongly coupled anyon material at finite density and temperature. We study the transport properties of the material and find both diffusion and massive holographic zero sound modes. By studying the anyon number conductivity we also find evidence for the anyonic analogue of the metal-insulator transition.Comment: 19 pages, 6 figure

The Occurrence of \u3ci\u3eDitylus Caeruleus\u3c/i\u3e in Michigan (Coleoptera: Oedemeridae), With Observations on Its Range

The oedemerid beetle, Ditylus caeruleus, is recorded for the first time from Mar- quette County, Michigan. Bionomical data associated with the specimens represent the first such information for this species. Eight additional new Michigan county records for the species are also reported, including the first specimens from the Lower Peninsula. The distributional range of caeruleus is highly correlated with the Great Lakes, the 81. Lawrence River, and coastal Maine. Implications of this distribution pattern relating to possible development of larvae in driftwood and the potential significance of rafting as a dispersal mechanism are also discussed

Cantharidin and Insects: An Historical Review

The defensive role played by cantharidin in meloid and oedemerid beetles has been well documented. However. several groups of insects are known to orient positively toward the chemical or to the beetles which produce it: Miridae (Hemiptera); Pyrochroidae, Anthicidae (Coleoptera): Ceratopogonidae, Anthomyiidae (Diptera); and Braconidae Hymenopteran. Literature citations are summarized for each of these taxa using current nomencla.tun: and indicating the nature of the association

Description of the Larva of \u3ci\u3eDioedus Punctatus\u3c/i\u3e LeConte (Coleoptera: Tenebrionidae)

Larvae of Dioedus punctatus LeConte have been collected from logs, probably Ulmus americana, in the red-rotten stage of decay and determined from reared adults. They are described and illustrated
