BARINI. 319 



sides parallel, rounded, and feebly constricted near the tip; base nearly 

 straight- .Elytra elongate, very little wider than the prothorax, conjointly 

 rounded at tip, pygidium completely covered. Prosternum moderately 

 long in front of the coxse, which are very slightly separated; mescsternum 

 rather narrow, metasternum long, hind coxte widely separated. First, 

 second and fifth ventral segments long, third and fourtli together a little 

 longer than tlie second; first suture parti}' obliterated at tUt; middle; the 

 others are distinctly curved at the sides. Legs rather slender, tibi* feebly 

 but distinetljf mucronate; tarsi with the third joint very broad, bilobed, 

 last joint rather long, with a single claw. 



1 B. filiforme, n. sp. 



Elongate, nearly filiform, black, clothed with small pale scales. Beak 

 naked, shining, punctured; head thinly pubescent, punctulate. Prothorax 

 rather densely, but not very strongly punctured, with the scales lying 

 transversely, as in many Centriims- Elytra with fine striae, and flat, alu- 

 taceous interspaces. Legs brownish- Length 2.5-3.3 mm.; .1C-.13 inch. 



Virginia, Illinois, Nebraska; three specimens. 



EUCH^TES n. g. 



Body resembling in form a r.)bust Centriivux, but with comparatively 

 larger prothorax, more rounded on the sides; covered with a deiise crust 

 of dirt-colored scales, and with very long stiff erect bristles. Beak nearlj^ 

 as long as the body, much stouter from the base to the insertion of the 

 antennae, then slender and strongly curved for the remaining two-thirds 

 of the length, base constricted beneath, and somewhat protuberant; anten- 

 nal grooves confluent behind; eyes transverse, finely granulated; head im- 

 mersed in prothorax nearly to the eyes. Antenna? with the scape extend- 

 ing to the eyes, gradually thickened externally; funicle 7-jointed slender, 

 longer than the scape; first and second joints longer, equal; seventh 

 broader, rather closely connected with the club, which is elongate-oval, 

 pubescent, and indistinctly annulated. Prothorax rounded on the sides, 

 slightly bisinuatc at base, narrowed and tubularly constricted at tip, with- 

 out postocular lobes. Scutellum larger than usual. Elytra narrowed be- 

 hind, tips separately rounded, pygidium not exposed. Prosternum trun- 

 cate in front, stronglj' impressed transversely, not foveate, nor flattened; 

 front coxoe very widely separated; middle and hind coxse very widely sep- 

 arated; side pieces of mesothorax of the same form as in CentrliiHs; those 

 of the metathorax narrow. First and second ventral segments very large, 

 third and fourth united shorter than either, fifth a little longer than fourth. 

 Legs moderate, thighs sinuate, and somewhat clavate; tibiae nearly as long 

 as the thighs, straight, strongly unguiculate at the outer side of the apex; 

 tarsi rather long, slender, third joint not wider than the second; fourth 

 joint as long as the others united, with rather large, divergent, simple 

 claws. 



This is one of the most remarkable insects in our fauna, from the length 

 and stiffness of the bristles, Avhich are almost spiniform.
