EPHALTJS, Lee. 

 Bphalus, Lee, Class. Col. N. A., p. 327. 



Broadly oval, convex, resembling Ccelus. Epistoma deeply emarginate, sides of fronf 

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

 joint of maxillary palpi feebly triangidar, longer than broad. Antenna? ver) shorl clavate, 

 first two joints broader, second and third equal in length, four to eL ven verj 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. Epipleura? broad, 

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

 margins ol third and fourth ventral segments distinctly sub-coriaceous, feebly annate. An- 

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

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

 third together. Bod) apterous. 



The form of the anterior tibiae 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 Lacordaire 

 or any of the " Branches" defined by Mulsant. 



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



Form similar to Ccelus or Eusattus eonvexus. 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 Xew 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 ol generic limitation. The epistoma 

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

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

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

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

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

 winged. The (interior tibia? are triangular and the spurs large. 



('. se ricca, elongate oval, sub-parallel, moderately convex. Head Bub-quadrangnlar, broader than long, emar- 

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

 denselj and Bnely punctured, aud densely clothed with a yellowish, grey, recumbent silken pubescence. Thorax tra- 

 pezoidal, sliylitly narrower behind and broader than long, moderate!] couvex, densely and finely punctured and densely
