CERCOPEUS Schonh. 



Cercopeus Schonherr, Gen. Cure, vii, 1, p. 154. 



Rostrum slightly longer and narrower than the head, feebly arcuate, an- 

 gulate, truncate at tip. Scrobes superior, very short, deep. Antennae sub- 

 terminal, scape feebly arcuate attaining the thorax, funicle 7-jointed, joints 

 1-2 longer, the first stouter, joints 3-7 short moniliform, club moderate, 

 oval. Eyes small rounded, surrounded by a very distinct groove. Thorax 

 transversely oval, broadly arcuate on the sides, apex and base truncate. 

 Elytra oval, very slightly attenuate behind, humeri broadly rounded. 

 Tibiae mucronate, the anterior more strongly. Claws free. 



The deciduous pieces of the mandibles are cylindrical, flattened and very 

 obtuse at tip. The scar left after the separation is extremely feeble.

 Boh. Sch. Gen. Cure., ii, p. 517. 



Form oval, color brownish, densely covered with ochreous scales, elytra 

 with large discal space ; somewhat cordiform in shape, darker in color. 

 Head and rostrum moderately densely punctured.' Thorax transversely 

 oval, somewhat broader .than long, apex and base truncate, sides rather 

 strongly arcuate, disc moderately convex, densely punctured, becoming at 

 times strigose at the middle, surface sparsely scaly. Elytra oval slightly 

 attenuate behind, humeri broadly rounded, striate, striae punctured, inter- 

 vals flat, densely scaly and uniseriately setigerous. Body beneath very 

 sparsely scaly. Legs sparsely scaly and slightly hairy. Length .12-. 20 

 inch ; 3-5 mm. 



Variable in the color of the scales covering the surface from luteous to 

 brown but always showing the darker, discal spot on the elytra. 



Occurs from Pennsylvania to Georgia. 



CH^ETECHUS n. g. 



Rostrum not longer than the head and as stout, parallel, quadrangular, 

 tip truncate and with small smooth triangular space. Scrobes lateral mode- 

 rately deep, sides divergent passing above and beneath the eyes. Eyes 

 small, round and with distinct orbital groove. Antennae stout, insertion 

 sub-median, scape moderately robust, feebly arcuate, attaining the margin 

 of thorax, funicle 7-jointed, the first two longer and the first much stouter, 

 joints 3-7 moniliform, club oval. Thorax feebly transversely oval. Elytra 

 oblong oval, sides at middle parallel. Scutellum indistinct. Second seg- 

 ment of abdomen longer than either of the two following, separated from 

 the first by a feebly arcuate suture. Intercoxal process of first segment very 

 broad and short. Tibiae strongly mucronate at tip. Claws free. 



This genus is very distinct from all the other Trachyphlazi by the charac- 

 ters above given although not without considerable affinity with both Tra- 

 chyphlaius and Cathormiocerm. The eyes are small, round, coarsely granu- 

 lated, surrounded on all sides with a very distinct orbital groove. The 

 scrobes are deep, pass directly backwards to the eye, the upper bounding
