Scutel flat, oblong, triangular, with piliferous punctures. Elytra longer than the prothorax, widest posteriorly, and rather wider than long; black with piliferous punctures, lateral margin yellowish brown, hair yellowish upon the disk, and fulvous upon the lateral margin.

NBCROPHORUS OBSCURUS, Kirby. Fauna Bor. Amer; p. 97.- Valley of Great Salt Lake. ELEODBS COGNATA, Hald. Colour, size, and markings as in IS. extricata, but the puncturing is much finer, and that of the pronotum more sparse.

Two specimens in Captain Stansbury's collection. NTOTOBATBS ( IPHTHINUS) INTERMEDIA, Hald. Allied to N. barbata, Enoch ( Tenebrio) NeueBeytraege, p. 166, fig. ( 8triato- punctatU8j Dejean, Catalogue, p. 225) and similarly barbate with fulvous hair. Punctures of the head larger and more crowded ( especially upon the vertex.) Pronotum with the sides more rounded and the surface more coarsely punctured. Surface of the elytra minutely but more distinctly punctured, and the nine lines of punctures less distinct than in N. barbata. This species agrees in size and colour with N. barbata, and in distinctness of the lines of punctures upon the elytra it stands between that species and N. pennsylvanica. Western Texas.
