COLEOPTERA OF SOUTHERN CALIFORNIA. 269' 



then strongly rounded and witli a very short apical constriction; surface 

 strongly and rather coarsely punctate, the punctures as a rule separated 

 by less than their own diameters; they are somewhat finer and less close 

 at the middle of the disk anteriorly, and at the extreme sides are more or 

 less coalescent, forming longitudinal rugae; disk without median smooth 

 line or with but faint traces of it. Elytra a little less than twice as long 

 as the prothorax, slightly wider, the sides feebly convergent posteriorly 

 and broadly elliptically rounded at apex; strias rather fine, moderately 

 deep, obsoletely punctate; intervals flat, about two and one-half times as 

 wide as the strife; the second and third fully three times as wide as the 

 strife; second, third, and ninth with more or less confused punctuation,, 

 the other intervals with a single series which is, however, somewhat con- 

 fused or inegular at base; the punctures as a rule not more than one-third 

 as wide as the intervals, and distant from each other by about their own 

 diameter. Beneath rather coarsely and closely punctate; prosternum 

 nearly flat, the front coxfe separated by rather more than half the coxal 

 width. 



Length, 3.4-4 mm. 



Described from a good series taken by Mr. F. S. 

 Daggett in Bear Valley (San Bernardino Mountains), 

 at an elevation of about 6,400 feet. 



B. monticola would fall next to B. aprica according to- 

 Casey's table, but it is very distinctly different in its 

 finely punctate elytral intervals, among other charac- 

 ters. The prothorax is scarcely more strongly declivous 

 in front, as is described of the section in which the 

 elytra are less than twice as long as the prothorax, and 

 to which B. ononticola is therefore referred. The setse 

 of the upper surface are very short and inconspicuous. 



91. Sphenophorus tardus, sp. no v. 



Moderately robust, black, feebly shining. Beak one-half the length of 

 the prothorax, distinctly arcuate, moderately compressed; pviuctuation 

 sparse and minute except at base, the usual puncture between the eyes, 

 before the puncture a short, fine, impressed line. Prothorax longer than 

 wide, sides evenly arcuate, a little convergent anteriorlj', apex constricted;, 

 surface without grooves or elevations, densely, moderately coarsely punc- 

 tate, with a narrow, median, smooth space, or line, which reaches neither 

 base nor apex. Elytra not at all, or scarcely wider, and but little longer,.
