Elytra rather densely punctured in longitudinal bands which are separated by 

 narrower smooth lines. 



Elytra without well-defined third stria 2. incomptus. 



Elytra with a well defined though shorter third inner stria at sides. 



Lateral striae coarser, third stria more median in position, size smaller (Penn- 

 sylvania to Texas) 3. I risl rial us. 



Lateral striae fine, third 'stria more posterior, size larger (California). 



4. nlkei. 

 Elytra more sparsely punctate, the punctures frequently forming more or less 

 regular rows, but not arranged in longitudinal bands, except obscurely 

 in levisternus. 

 Submarginal strife entire, and nearly equally deep from base to apex. 

 Elytra with an inner third stria. 



Third stria median in position 5. levisternus. 



Third stria basal 6. grnnus. 



Elytra with two lateral strife only 1. intermedins. 



Submarginal strife abbreviated, or at most very faintly impressed at base. 

 Base of metasternal lobe evidently narrowed by tarsal grooves; metasternum 



distinctly punctate 7. fallax. 



Base of metasternal lobe scarcely at all narrowed by tarsal grooves ; meta- 

 sternum nearly impunctate 8. facilis. 



1. E. intermedins Lee— Broadly oval, shining black, the mouth and legs 

 more or less rufous or rufescent. Pubescence sparse, gray, erect or suberect. 

 Antennae 8-jointed (see figure). Eyes moderate, separated on the front by less 

 than twice their vertical diameter. Head sparsely punctulate; prothorax finely 

 but more closely punctate; elytra more strongly punctate in irregular rows and 

 with two entire or subentire marginal strife. Metasternum sparsely rather finely 

 punctate, median sulcus obsolete posteriorly, terminating anteriorly in an elon- 

 gate fovea. Ventral segments finely, moderately closely punctate, the sutures 

 deep from side to side and scarcely or feebly arcuate at middle. Length 1.7-2.2 

 mm. 



Specimens are known to me from Massachusetts (Tyngsboro) j 

 New York; Virginia (Pennington Gap and Roslyn) ; West Vir- 

 ginia (Fort Pendleton); Ohio (Cincinnati); Michigan (Grand 

 Ledge and Detroit); Arkansas; North Carolina (Highlands); 

 Florida. 



2. E. incomptns Lee. — Oval, moderately elongate, brown or piceous, head, 

 pronotum (rarely), under surface and legs rufous, antenna? and tarsi pale; pubes- 

 cence recumbent or subrecumbent, yellowish gray. Eyes separated on the front 

 by more ( £>) or less ( % ) than their vertical diameter, the distance in the % 

 equaling very nearly the ocular width as seen from the front. Antennas 10- 

 jointed, the eighth and ninth joints ( % ) strongly transverse, rather deeply emar- 

 ginate apically, the tenth somewhat arcuate ; club much smaller in the female. 

 Head, pronotum and under surface finely, nearly evenly, and not closely punc- 

 tate. Elytra finely closely punctate in longitudinal bauds, which are separated
