314 Goleopterological Notices, VII. 



edge of the apex obliterated toward the middle, narrow; reflexed margins 

 fine; surface moderately convex, the median, subapical and subbasal lines 

 rather deep, also with the sublateral diverging impressions well marked. 

 Elytra oval, strongly convex, pointed at apex, rather full toward base, % 

 longer than wide, 2^5^ times as long and 2}4 times as wide as the prothorax; 

 reflexed margins narrow; striae rather coarsely and deeply impressed, irregular 

 toward the sides, almost evenly spaced toward the suture, the punctures 

 rather fine and widely separated; intervals convex. Length 14.5 mm.; 

 width 7.0 mm. 



Northern California ? 



A remarkably distinct species in the very strongly oblique and 

 feebly sinuate sides of the prothorax posteriori}- and unusually 

 narrow base of the latter, rather abbreviated head, and complete 

 lack of any trace of the nuchal constriction which is such a 

 prominent feature of cristatus, hasalis and duplicatus. The inter- 

 coxal plate of the mesosternum is perfectly flat, with the edges 

 abruptly but narrowly reflexed. It should probably be placed 

 near rugiceps, and is represented by a single very immature 

 female specimen, without locality label but possibly from the re- 

 gion indicated above.

Elongate-oval, rather strongly ventricose, shining, the prono- 

 tum alutaceous ; head alutaceous, the frontal portions jDolished. 

 Head stout, the gense generally with a small angular nick ; a 

 transverse impression behind the eyes vaguely suggested ; anten- 

 nae not quite f as long as the body, slender and with the basal 

 joint somewhat stout, obconic and much shorter than the two fol- 

 lowing combined. Prothorax relatively large, much dilated and 

 rounded anteriorly, strongly sinuate before the base, the sides 

 parallel and straight in less than basal fifth, the base broad, rather 

 wider than the head, the apex broadl}' sinuate ; disk much wider 

 than long, longitudinally quite convex, the impressions rather 

 feeble ; side margins moderatel}^ reflexed. Elj^tra elongate, 

 evenly elliptical, widest at the middle, ^ longer than wide, 3^ 

 times as long as the prothorax and a little more than twice as 

 wide ; margins moderately reflexed ; disk moderately convex, 

 finely striate, the strise not coarsely but distinctly punctured, 

 much confused broadly near the sides ; intervals flat, each with a 

 supplementary series of punctures especially behind the middle. 

 Length 17.0-22.0 mm.; width 8.5-10.0 mm.
