NORTH AMERICAN* COLEOPTERA. 23 



tenth, rather finely acuminate at the tip. Protliorax just perceptibly wider 

 than the head ; sides nearly parallel and rather strongly arcuate to a point 

 slightly behind the middle, then strongly convergent posteriorly and nearly 

 straight ; anterior angles broadly rounded, posterior very obtuse, though 

 distinct and but slightly rounded ; width two-fifths greater than the length ; 

 apex much longer than the base, equally arcuate ; disk evenly convex, 

 strongly punctate, punctures round, small, impressed, generally separated 

 by more than twice their own widths, interspaces convex and very highly 

 polished ; toward the basal angles there are several large, deep punctures 

 irregularly disposed. Elytra at base as wide as the prothorax ; sides strongly 

 divergent posteriorly, shorter than the width at base, strongly and evenly 

 arcuate ; together broadly, roundly, and strongly emarginate behind ; suture 

 very slightly more than three-fourths as long as the pronotum ; surface feebly 

 punctate, punctures round, generally separated by more than twice their 

 own widths, becoming much more feeble, almost obsolete, posteriorly. First 

 three abdominal segments as wide or wider than the contiguous elytra ; sides 

 parallel and rather strongly arcuate ; border strong ; surface minutely granu- 

 lose or reticulated, feebly shining. Legs moderate ; first joint of posterior 

 tarsi slightly shorter than the fourth, fourth equal in length to the second 

 and third together. Prosternum feebly and coarsely punctate in its anterior 

 third. Metasternum impunctate, not darker than the remainder of the under 

 surface, distinctly carinate anteriorly in the middle. 



Male. — Unknown. 



Female. — Sixth ventral segment broadly angulate at apex. 



Length 1.3 mm. 



Tallahassee, Florida; two specimens. 



This species greatly resembles brevipennis, but differs in many 

 minor characters. In the latter the prothorax is I'elatively much 

 longer, is widest behind the middle, and is very closely punctate ; in 

 similis the prothorax is much shorter and broader, is widest before 

 the middle, and is more deeply and sparsely punctate ; the elytral 

 suture is relatively longer in similis, and the elytral punctures are 

 much more distant, slightly coarser and more feeble than in brevi- 

 2)ennis. 



5. E. iniindllllis n. sp. — Form slender. Pubescence sparse, rather 

 fine and long, semi-erect, piceous. Color dark castaneous, antennae and 

 legs paler. Head moderate, very slightly wider than long ; interocular 

 surface coarsely, strongly, and nearly evenly punctate, punctures round, 

 shallow, very distinctly defined, generally separated by their own widths ; 

 antennal tuberculations very distant, small, and very prominent ; teeth of 

 labrum twice as long as their distances asunder ; antennae moderate in 

 length, joints three to five decreasing nearly uniformly and just perceptibly 

 in length, sixth and seventh shorter, sub-equal in length, the latter much 

 thicker, oval, eighth small, globular, ninth strongly transverse, oval, slightly 

 longer than the eighth, tenth two-fifths wider than the ninth, as broad as 

 long, cylindrical, eleventh as long as the two preceding together, sides nearly
