REVISION OF THE TENEBHIONIbVE OF AMERICA, 



EPHALUS, Lee. 

 Ephalus, Lee.', Class, Col, N. A., p. 227. 



Broadly oval, convex, resembling- Coslus. Epistoma deeply emarginate, sides of front 

 slightly sinuous, forming an angle in front of the eyes, which are feebly emarginate. Last 

 joint of maxillary palpi feebly triangular, longer than broad. Antenna; very short clavate, 

 first two joints broader, second and third equal in length, four to eleven very short, trans- 

 verse and perfoliate, the last joint being slightly narrower and longer than the preceding. 

 Thorax applied against the base of elytra, Scutellum small, transverse. Epipleurse broad, 

 concave, incomplete behind. Tntercoxal process of abdomen short, obtuse in front Hind 

 margins of third and fourth ventral segments distinctly sub-coriaceous, feebly arcuate. An- 

 terior tibia' flat, triangular, outer apical angle not prolonged. Spurs small. Hind tarsi 

 with the last joint slightly longer than the first, and both longer than the second and 

 third together. Body apterous. 



The form of the anterior tibia 1 and intercoxal process of abdomen, and more especially 

 the structure of the antenna', indicate this genus as the type of a, sub-tribe distinct from 

 that represented by the preceding genus, differing also from the Stizopodes of La.corda.ire 

 or any of the " Branches" defined by Mulsant. 



E. latiiiKinus, Lee., (Heliopates) Journ. Acad. Series 2, 1, p. 02. 



Term similar to Ccelua or Euaattua convexua. Black, opaque. Margin of body fringed 

 with yellowish hairs Surface rather densely muricately punctured, each puncture bearing 

 a small yellowish hair. Elytra very faintly sub-striate. 



Length .30-.36, width .20-.24 inch. 



Rather rare in the New England States. 



CNEMEPLATIA, Costa. 



To this genus I refer a very rare insect collected by myself in Owens' Valley, Califor- 

 nia. Specimens of the rare European species of Cnemeplatia are before me, and I am un- 

 able to detect any differences not within the bounds of generic limitation. The epistoma 

 is rather more deeply emarginate and tin; edge slightly more reflexed. The front in Cne- 

 meplatia has a slight impression on either side, not evident in this insect. The epipleu'ree 

 are entire in both, and the intercoxal process triangular and acute. The palpi are rather 

 short, the last joint of .maxillary oval. The antennas are similarly constructed, although 

 the last three joints are in the California species somewhat broader. Both species art; 

 winged. The anterior tibiae are triangular and the spurs large. 



C. sericea, elongate Oval, sub-parallel, moderately convex. Head sub-quadrangular, broader than long, emar- 

 ginate in front and with slightly reflexed margin, eyes prominent, feebly emarginate in front, surface feebly convex, 

 densely and finely punctured, and densely clothed with a yellowish, grey, recuinbent silken pubescence. Thorax tra- 

 pezoidal, slightly narrower behind and broader than long, moderately convex, densely and finely punctured and densely
