and rather distinctly impressed and entire elytral stride giving it a 

 peculiar appearance. Although the eyes are distinctly more promi- 

 nent than the sides before them, they are much less so than in 

 ma7'ginatus. 



In common with all the winged species except longulus, the pre- 

 sent appears to be quite rare and I have seen only the unique type. 



E. margiuatus n. sp. — Oblong, parallel, somewhat depressed, dark 

 rutb-testaceous, the legs and antennje paler and more flavate ; integuments 

 highly polished throughout. Head short and broad, rather coarsely, densely 

 punctate ; sides rapidly convergent from base to apex, the eyes large, very 

 convex and very much more prominent than the sides of the head ; epistoma 

 narrow at apex, rather feebly but distinctly sinuate ; supra-orbital ridges fine 

 but distinct, extending well beyond the eyes, obsolete at the middle of their 

 upper margin ; antennse slender, with a loose elongate club. Prothorax fully 

 four-fifths wider than long, the apex rather distinctly narrower than the base, 

 distinctly emarginate in circular arc, the apical angles rather acute and not 

 at all rounded ; base transverse, very feebly sinuate at each side of the middle, 

 the angles slightly obtuse but not at all rounded ; sides evenly and moderately 

 arcuate ; disk very slightly wider just behind the middle than at base, coarsely, 

 rather densely punctate, the punctures becoming gradually longitudinally 

 confluent toward the sides, the latter very narrowly but distinctly explanate. 

 Elytra about three and one-half times longer than the prothorax and subequal 

 to it in width, very slightly wider behind ; apex ogival ; sides subparallel, 

 very slightly more arcuate behind ; disk with feebly but distinctly impressed 

 striae, which extend unbroken almost to the apex, the strise rather coarsely 

 and very approximately punctured, the intervals flat, each with a moderately 

 even series of distinct but smaller punctures, those of the sutural interval 

 confused. Abdomen finely very sparsely punctate, the surface slightly scabrous 

 and the punctures larger and closer near the sides. Legs long and slender, 

 the posterior tarsi almost as long as the tibipe. Length 6.5 mm. ; width 2.8 mm. 



Lower California. 



A very distinct species, peculiar in its very prominent eyes ; in its 

 impressed elytral striae it somewhat resembles texanus, but differs 

 greatly in the structure of the epistoma. 



E. longulus Lee. — Ann. Lye. N. Y., V, p. 139 (Eurymetojwn). — Elongate- 

 oval, sometimes feebly inflated behind, rather strongly convex, highly polished 

 throughout, blackish to rufo-piceous in color, the elytral setae extremely 

 minute, not attaining the external limit of the punctures. Head scarcely 

 one- fourth wider than long, rather finely but deeply and densely punctate; 

 epistoma transversely truncate or extremely broadly, feebly sinuate ; eyes 

 moderate, the ridges extremely fine and feeble, not extending much beyond 

 the eye ; antennae long and slender, the club slender and loose. Prothorax 

 about two-thirds wider than long, the apex slightly narrower than the base.
