tarsi is very distinctly lobed. 
78. Cyphon impressus, n. sp.—Elongate-oval, not convex, piceous, 
pubescent. Antenne and legs piceo-testaceous. Head, prothorax and 
elytra equally densely punctulate, the last without elevated lines ; about 
one-sixth from the base is a strong curved impression extending to the su- 
ture, and behind the middle a still deeper oblique one, not attaining the 
suture ; between these two pairs of impressions the suture is slightly ele- — 
vated. Antenne with the 3d joint slender, equal in length to the 2d, not 
shorter than the 4th. Length 2.3 mm.; .09 inch.
