376 APPENDIX C. — INSECTS. 



upon each side of the middle, a second line of three exterior to 

 these, (two placed opposite the interstices of the posterior three, 

 and the third at the posterior margin,) a third row of three or 

 four exterior to the latter, followed by a single puncture in the 

 lateral angle : there are also several marginal punctures poste- 

 riorly. 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. Wings fuliginous irised. Tergum, under parts 

 and feet with piliferous punctures. Length, six lines. A single 

 specimen collected by Mr. Kern, of which the antennae are broken. 



Necrophorus obscurus, Kirby. 

 Fauna Bor. Amer. p. 97. — Valley of Great Salt Lake. 



Eleodes cognata, Hald. 



Colour, size, and markings as in E. extricata, but the punctur- 

 ing is much finer, and that of the pronotum more sparse. The 

 elytra have distant, minute elevated points, (some of them con- 

 nected with the punctures,) which are more evident posteriorly. 

 Valley of the Great Salt Lake. 



Eleodes obscura. Say. 

 Two specimens in Captain Stansbury's collection. 



Nyctobates (Iphthinus) intermedia, Hald. 



Allied to iV. harhata,K.TLOch. (Tenebrio) Neue Beytraege, p. 166, 

 fig. (striato-punctaUis, 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 JV. harbata. 



This species agrees in size and colour with JV. barhata, and in 

 distinctness of the lines of punctures upon the elytra it stands* 

 between that species and JN'. pennsylvanica^ Western Texas. 



ZOPHERUS VARIOLOSUS, Sturm. 



Described from Mexican specimens ; is found at Fort Gates. -
