 I. c. ; Schaupp, I. c, p. 76, pi. 1, fig. 5. 

 Length 13.5 nim.= .54 inch. 



Habitat— Mountains near x\llegbany City, Sierra Co., Cal. (4000- 

 5000 feet). September. 



Differs from all the other species by its bronze color. The form is 

 elongate, nearly parallel and cylindrical, the elytra broadest near the 

 apex. Mr. Fuchs writes me, " the type was found by James Behrens 

 (fide Behrens), not by Henry Edwards," and the locality and season 

 were as above stated. 



O. laevis Horn, 1366, Proc. Ac. Nat. Sci. p. 394; Schaupp, /. c, p. 77, pi. 1, fig. 

 10. 



Length 14-18 ram. = .56-.72 inch. 



Habitat—Tnohimne Meadows, Tuolumne Co. (9000 feet) ; Fresno 

 Co., Tulare Co. (3000-5000 feet). Type was found in the High Sierra 

 near the head waters of King's and Tule Rivers. June. 



Differs from all the other species in being almost entirely smooth 

 and subopaque ; the elytra are regularly oval, exhibiting a few almost 

 obsolete punctures in the type, but evidently punctate in most of the 

 other specimens I have seen.

 convex, deeply punctate.

 emarginate ; tip of elytra subtruncate ; sutural angle rectangular.
