 punctulate, the labrum with a rather narrow truncate median projec- 

 tion ; pronotum not rapidly declivous laterally, the anterior angles 

 distinct from above, the sides broadly rounded, more converging 

 basally, the lateral margins attaining the basal bead, the surface 

 strongly rugose throughout ; elytra short, three-fifths longer than 

 wide, oval, the humeri rather evident, though broadly rounded and 

 subequally so in both sexes, the surface coarsely, closely and irregu-

A — Rather less convex, slightly larger and less ventricose, the elytra 

 notably more, elongate, deep black, almost as shining; head with 

 the rugae less coarse and much deeper throughout, the labrum 

 broadly and evenly arcuate medially ; prothorax relatively a little 

 larger in the male and more nearly equal in relative size in the two 

 sexes, the sides still more rapidly converging behind the middle in 

 the male, the rugae even deeper and similarly equal and dense 

 throughout ; elytra more elongate, the sculpture rather less coarse, 

 less irregular and rather denser ; male and female more nearly 

 equal in size. Length, ^ , ? , 14.5-16.0 mm.; width, 5.3-6.0 mm.

6 — Elytra widest before .the middle, gradually narrowing and with less 

 arcuate sides thence to the apex, black, shining, the head sparsely 

 rugose, smooth anteriorly ; prothorax slightly wider than long, 

 obtrapezoidal, the sides arcuate and gradually converging to the base, 

 the surface feebly shining, intricately wrinkled, but not so strongly as 

 in Califormcus, the median line nearly obsolete, the anterior trans- 

 verse impression very faint ; elytra shining, with large punctures, each 

 distinct and with feeble fovese. Length, $ , 17.0 mm. Vicinity of 



Monterey LeContei, G. H. Horn 



Elytra regularly oval or, in the female, slightly shouldered, widest at about 



the middle 7 



7 — Pronotum almost plane medially, somewhat as in sequoiarum. Differs 

 from LeContei in having the head anteriorly finely rugulose and the 

 median stria of the pronotum almost obsolete ; antennae long and 

 stout; hypomera broadly visible frOm above. Length, 16. 0-18. 5 mm. 

 Probably from vicinity of Monterey .; possibly a composite, the male
