act. Front not concave; scales with brassy lustre. 718. SCANDEXS. 



717 ( ). MECOPELTUS IULIGINOSUS Dietz, 1896, 467. 



Oval. Pitchy-black; above thinly clothed with grayish scales, faintly 

 mottled with whitish ones and pale pubescence; beneath more densely cloth- 

 ed with grayish scales; sides of thorax densely clothed with dirty yellowish 

 scales; antenna? and legs raddish-brown. Beak longer than head, gradually 

 widening from base to tip, densely punctate, each puncture bearing a fine 

 scale. Thorax one-half wider than long, sides rounded in front of middle; 

 apical cusps and lateral tubercles large and acute, dorsal channel entire, 

 expanding near apex into a triangular impression; disc densely and finely 

 punctate. Elytra oval, one-third wider at base than thorax, sides broadly 

 rounded; strife with close-set punctures: intervals feebly convex, the outer 

 ones each with a row of minute, acute granules bearing short recurved 

 seta?. Length 2.7 3 mm. 



Recorded from Newark, N. J. Ranges from New England and 

 Canada to Oregon, south to Texas. "Resembles Pelc-nomus sul- 

 cicollis, but larger, more sombre and has the ante-coxal ridges.*

 Mccopeltus, are only short, acute, elevations in this species, and easily overlooked.
