11. E. COllflueus Lee. — Bost. Joiirn. YI. p. 105. — Form slender, de- 

 pressed ; sides parallel. Pubescence rather fine and dense, recumbent, very 

 pale ; color of body pale reddish-testaceous, elytra sometimes slijjhtly paler 

 than the head and prothorax, antennae and less scarcely paler. Head very 

 large, Hat above, slightly wider than long; eyes rather small, moderately 

 prominent ; genae prominent, obtusely rounded, slightly longer than the 

 eye ; base transverse, distinctly sinuate in the middle ; interocular surface 

 coarsely strongly* and closely punctate at the sides, impunctate along the 

 middle, having a strong median carina at base, very flat throughout behind, 

 having two minute naked foveae at one-third the length from the base, 

 iiiutually as distant as either from the adjacent eye ; intermediate surface 

 feebly convex, each fovea is continued anteriorly by a moderately deep 

 irregular canaliculation, the two being parallel and scarcely joined ante- 

 riorly ; supra-antennal tuberculations rather prominent, joined by a very 

 broadly arcuate and rather feeble ridge ; antennae barely one-third longer 

 than the head, rather slender, club small, joints three to eight very small, 

 moniliform, equal in width, eighth shortest, ninth one-half wider than long, 

 wider than the eighth, equal in length to the tenth, tenth oue-third wider 

 than the ninth, eleventh very slightly wider than the tenth, nearly as wide 

 as long, sides parallel ; second joint of the maxillary palpi long, feebly 

 clavate. Prothorax widest distinctly before the middle where it is just per- 

 cepti1)ly wider than long and distinctly narrower than the head ; sides very 

 feebly sinuate anteriorly, minutely undulated but nearly straight posteriorly, 

 very strongly convergent; apex scarcely one-half as wide as the greatest 

 pronotal width, three-fourths as long as the base, both very feebly arcuate; 

 disk very feebly and coarsely punctulate, shining, having an elongate medial 

 canaliculate puncture, also a small very deep medial fovea at one-fourth the 

 length from the base, which is sometimes partially confluent with the medial 

 canaliculation, also two lateral d(;eply impressed foveae not connected with 

 the medial one by an impressed channel. Elytra at base as wide as the 

 pronotum ; sides nearly parallel, feebly arcuate ; disk depressed, slightly 

 longer than wide and slightly shorter than the head and pronotum together, 

 polished, scarcely punctulate ; humeri prominent ; sutural striae very strong, 

 arcuate toward the apices, approximate, lateral distinct, becoming obsolete 

 at two-fifths the; length from the base. Abdominal segments nearly as wide 

 as the elytra, very gradually increasing in width posteriorly ; first three of 

 equal length ; first two dorsals with two short rather approximate strongly 

 divergent and feeble carinae ; border strong, flat ; surface feebly convex, 

 shining, scarcely punctate. Legs short and slender. Length 1. '2-1.4 mm.

The description is taken from Dr. LeConte's type, a female. The 

 males are smaller and apart from a slightly more slender antenna, 

 j)resent no appreciable difference, except in regard to the sexual 

 characters proper, which are very marked. The third ventral seg- 

 ment is abruptly and strongly bisinuate in its middle third at apex;
