middle; interocnlar surface impiuictate and highly polished, witli an elon- 

 gated median puncture at the base, and two small, circular, spongy-pubes- 

 cent foveae at more than one-third the length from the base, and but slightly 

 more widely separated than either from the corresponding eye; intermediate 

 surface rather strongly convex ; from each fovea proceeds a narrow impressed 

 channel, the two being at first i:>arallel and then convergent, coalescing 

 anteriorly by a very wide channel behind the frontal ridge ; supra-antennal 

 tuberculations very strong, angulate externally, joined by a transverse and 

 very strong ridge ; antennae one-third longer than the head, moderately 

 slender, club somewhat robust, ninth joint no longer than the eighth, twice 

 as wide as long, tenth one-half longer and wider than the ninth, eleventh 

 very slightly wider than the tenth, scarcely wider than long, nearly globular, 

 abruptly acuminate at tip. Prothorax widest at one-third its length from 

 the apex, where it is slightly naiTower than the head, and as broad as long, 

 contiguous sides parallel for a short distance, thence convergent and broadly 

 reentrant behind ; apex one-half as long as the greatest width, and two- 

 thirds as long as the base, both feebly arcuate ; disk rather strongly convex, 

 polished, minutely and sparsely punctulate ; having a deep, elongated, 

 medial puncture slightly before the middle, also a large, deeply imjiressed, 

 medial fovea at a little more than one-fourth the length from the base, and 

 two lateral, circular, spongy-pubescent foveae behind the middle, connected 

 with the medial one by an extremely narrow and feeble groove, which is 

 scarcely visible. Elytra at base very slightly wider than the pronotum, and 

 about as wide as the head ; sides nearly parallel and rather strongly arcuate ; 

 disk distinctly longer than wide, and somewhat shorter than the head and 

 prothorax together, extremely minutely and sparsely punctulate, rather 

 feebly convex ; sutural striae strong, feebly arcuate, very close, lateral short, 

 broadly impressed ; humeri rather jirominent. Abdomen at base slightly 

 wider than the elytra ; sides feebly divergent posteriorly and straight ; first 

 two with two rather long and well-marked divergent carinae proceeding from 

 the extremities of transverse si^ongy-pubescent patches ; border strong, 

 nearly flat ; surface polished, feebly convex, scarcely punctulate. Legs well 

 developed ; middle femora slightly swollen. Length 1.2 mm.

Described from the unique type in Dr. LeConte's collection. 



6. E. congener n. sp. — Form rather slender. Pubescence somewhat 

 short, coarse, and dense, semi-erect, pale, and rather conspicuous ; color of 

 body rather dark reddish-testaceous throughout, legs slightly paler and more 

 flavate. Head rather large, slightly broader than long ; eyes large, promi- 

 nent ; genae not prominent, slightly longer than the eye, very convergent ; 

 base broadly sinuate, with a slight medial puncture ; interocnlar surface 

 slightly punctulate toward the eyes ; having, at slightly more than one- 

 third the length from the base, two minute, round, spongy-pubescent foveae 

 which are mutually scarcely more distant than either from the adjacent eye, 

 connected by an anteriorly arcuate parabolic channel, which also extends 

 divergently behind them toward the genae ; intermediate surface strongly 

 and narrowly convex, impunctate, and polished ; supra-antennal tubercula-
