tinct ; lateral lobes narrow, very narrowly rounded at apex, the sides nearly 

 straight thence to the eyes, the latter moderate, scarcely visibly prominent ; 

 surface rather finely, extremely densely punctate and scabrous, not trans- 

 versely 1 11 1 11 id anteriorly, the sides not reflexed ; antenna? moderate, the third 

 joint elongate. Prolhorax nearly twice as wide as the head, very nearly twice 

 as wide as long, the apex slightly narrower than the base, extremely feebly, 

 evenly emarginate in circular arc, the angles obtuse, not rounded but not in 

 the least prominent ; base transverse, the two median sinuations almost obso- 

 lete ; basal angles very broadly obtuse and narrowly rounded; sides rather 

 strongly and evenly arcuate ; disk slightly behind the middle distinctly wider 

 than at base, rather finely and feebly punctate, the punctures scabrous, 

 extremely densely crowded laterally, slightly separated toward the middle, 

 without trace of median line ; along the basal margin there is a rather thick 

 bead. Elytra about one-fourth wider than the prothorax and nearly four 

 times as long, at base equal in width to the base of the latter, the humeri not 

 exposed; apex broadly, obtusely rounded; sides subparallel and feebly arcu- 

 ate ; disk very convex, with ill-defined rows of small but deep punctures ; 

 intervals finely, confusedly punctate ; punctures much smaller and feebler 

 toward the suture, not distinctly asperate laterally. Abdomen very finely 

 rather sparsely punctate ; metasternura between coxa and groove just visibly 

 longer than the first ventral segment. Leys slender, moderate in length. 

 Length 5.4 mm. ; width 2.7 mm. 



California (Owen's Yalley). Cab. Horn and LeConte. 

 A rather small species, remarkable for its somewhat robust, com- 

 pact, very convex form and broadly obtuse thoracic angles. 



Ell. crassilltllll n. sp. — Oblong-oval, very convex, subalutaceous ; 

 castaneous to piceous-black ; legs and antenna? dark rufous. Head rather 

 large, moderately transverse; sides nearly straight and strongly convergent 

 from base to apex, the eyes moderately prominent ; median lobe of apex trun- 

 cate, very slightly produced, moderate in width, the lateral lobes moderate in 

 width and not reflexed at the sides ; surface even, rather finely, very densely 

 punctate and scabrous ; antenna? rather short but slender, the third joint 

 elongate. Prothorax scarcely two-thirds wider than the head, rather less than 

 twice as wide as long, the apex much narrower than the base, evenly and very 

 distinctly emarginate, the angles right, not at all rounded and distinctly 

 prominent anteriorly; base transverse, with two feeble median sinuations; 

 basal angles obtuse but not in the least rounded ; sides rather strongly arcu- 

 ate ; disk much wider behind the middle than at base, finely but distinctly 

 punctate, the punctures scabrous, very densely crowded laterally, slightly 

 separated toward the middle ; transverse basal bead distinct. Elytra but very 

 slightly wider than the prothorax and slightly more than three times as long, 

 at base equal in width to the base of the latter ; apex broadly rounded ; sides 

 very feebly arcuate, parallel ; disk very densely punctate, the punctures 

 rather distinctly asperate, arranged in approximate, moderately defined series
