specimens, the greatest variation being in the lustre; the species 

 may be known at once by the very broadly and distinctly, although 

 moderately, impressed strias. 



E. o"btusus Lee. — N. Spec. Col., 1866, p. 107. — Oblong-oval, convex, 

 moderately dull and alutaceous, smooth, black, the legs and antennae dark 

 rufous. Head moderately transverse, rather convex, finely, deeply punctate, 

 the punctures well separated but becoming very densely crowded on the epis- 

 toma, the latter very broadly arcuate or subangulate at apex ; eyes very small, 

 not at all prominent ; antenna? short and robust. Prothorax about two-thirds 

 wider than long, the apex about four-fifths as wide as the base, quite distinctly 

 emarginate in circular arc, the angles narrowly but distinctly rounded ; base 

 truncate, just visibly and broadly oblique laterally, the basal angles very 

 obtuse, not rounded, not in the least prominent ; sides evenly and rather 

 strongly arcuate ; disk a little wider just behind the middle than at base, 

 finely but deeply and distinctly punctate, the punctures generally separated 

 by from two to three times their width, but becoming somewhat abruptly 

 dense, a little larger but not confluent, in lateral fourth ; sides very minutely 

 and feebly beaded. Elytra perceptibly less than three times as long as the 

 prothorax and, in the female, subequal in width, but in the male distinctly 

 wider in the middle ; sides parallel, feebly arcuate, the apex rather strongly 

 but broadly parabolic ; disk with widely distant, slightly uneven, unimpressed 

 rows of small approximate punctures, the series confused near the apex, the 

 intervals very finely, somewhat sparsely, unevenly and confusedly punctate. 

 Abdomen very minutely, sparsely punctate, the punctures coarse but sparse 

 and feeble laterally. Legs moderate, the posterior tarsi rather distinctly 

 shorter than the tibiae. Length 5.8-6.8 mm. ; width 2.4-2.8 mm. 



California (Napa and Sonoma Cos.). 



One of the larger of the species having short robust antennas, and 

 readily distinguishable by the very distinctly arcuate sides of the 

 prothorax, convergent toward base, and the broadly obtuse but not 

 rounded basal angles. It is rather local and not abundant. 



The metasternum is scarcely three- fourths as long as the first 

 ventral segment; the basal groove is widely interrupted in the 

 middle, disappearing in a row of punctures at lateral fourth. 



E. ater Lee— Ann. Lye. N. Y., V, p. 139 (Eurymetopon).— Oblong-oval, 

 strongly, cylindrically convex, polished, black, the legs and antennae dark 

 rufous. Head moderate, nearly two-thirds as wide as the prothorax, rather 

 transverse, broadly, distinctly arcuate at apex, rather finely but deeply and 

 very densely punctate, the punctures usually sparser toward the occiput ; eyes 

 small, the fold short and fine but distinct ; antennae short, very robust. Pro- 

 thorax short and transverse, nearly twice as wide as long, the apex fully four- 

 fifths as wide as the base, evenly and rather distinctly emarginate in circular 

 arc, the angles right and narrowly rounded ; base truncate, the angles obtuse,
