merely very narrowly margined with cinereous at sides, suture and apex. 

 Legs black, cinereo-pubescent, tarsi black. Length .40-. 60 inch; 10- 

 15 mm. 



The form clothed over the entire surface with cinereous does not ap- 

 pear to be separable from that with the greater portion of the elytral sur- 

 face clothed with black, excepting in this one character alone. 



Occurs in the Middle States. 



E. funebris, nov. sp. 



Black, sub-opaque, moderately clothed with rather coarse black pubes- 

 cence. Head finely and densely punctulate, median line finely impressed, 

 surface sparsely pubescent. Thorax narrower than the head, slightly 

 longer than wide, sides at basal two-thirds parallel, at apex arcuate ; 

 surface densely punctulate and sparsely pubescent. Elytra gradually 

 divergent to apex, opaque, finely punctato-scabrous, and sparsely pubes- 

 cent. Body beneath and legs black, moderately shining, punctulate and 

 sparsely pubescent. Spurs of hind tibia? similar to each other, stout, 

 cylindrical, obliquely truncate and concave at tip. Length .76 inch ; 

 19 mm. 



Resembles E. fissilabris but differs by the form of the hind tibial spurs. 



Three specimens from Texas. 



E. fissilabris, Lee. Agassiz, Lake Superior, p. 232 ; Proc. Acad. 1853, 

 p. 339. 



Closely resembling the preceding species in sculpture and color, and 

 differs as follows : Thorax shorter, sides less parallel, spurs of hind tibia? 

 slender acute and of equal length, labrum more deeply emarginate. 

 Length .68 inch ; 17 mm. 



Occurs in the Lake Superior and Hudson's Bay Regions. 



E. corvina, Lee. Journ. Acad. IV, 1858, p. 21. 



Black, densely punctulate, feebly shining, sparsely pubescent with 

 short black hairs, aspect velvety. Head densely punctulate. Thorax 

 slightly wider than long, densely punctulate, sparsely pubescent, sides 

 parallel behind, at apical fourth arcuate. Elytra robust, slightly broader 

 to apex, surface minutely puuetured, very sparsely and finely pubescent. 

 Body beneath more shining than above, moderately punctulate and 

 sparsely pubescent. Length .80-1.10 inch ; 20-28 mm. 



The largest species of the genus in our fauna. The spurs of the hind 

 tibiie are acute at tip, slender, the outer somewhat stouter than the inner. 



Occurs from Colorado to Arizona.

Tbis species is so common and so well known that any description is 

 unnecessary. By its surface sculpture and pubescence it resembles E. 

 funebris and E. fissilabris, but differs from all the black species in having
