fourth longer than wide, having rows of coarse, deep, very distant 

 punctures ; intervals unevenly and rather coarsely punctured. Length

California (Kern Co. 1). 



The punctures of the eiytral intervals are not as large as those 

 of the rows, but are so unevenly distributed as to almost com- 

 pletely destroy the appearance of serial arrangement in the 

 latter, which appearance is increased by the great distance of 

 the serial punctures. 



SCIOPITHES Horn. 



The species of this genus are numerous in California; those 

 here described may be mutually separated as follows: — 



Antennal scape passing distinctly beyond the anterior margin of the- 

 prothorax. 

 Sixth joint of funicle distinctly shorter than the seventh. 

 Outer joints of funicle slender ; seventh joint in the female much 

 longer than either the fourth, fifth, or sixth, equal to the third, 

 and in the male very nearly as long. 

 Eiytral scales smaller, very minutely and feebly striate ; setae 

 generally finer and piceous ; surface markings strong and dis- 

 tinct ... signlRcans. 



Eiytral scales coarse, especially near the suture, very coarsely 

 and deeply striate ; setas more robust and squamose, pale ; 



surface markings very indistinct and suffused briiiiiali§. 



Outer joints of funicle more robust ; seventh but slightly longer 

 than the fifth or sixth, scarcely longer, but more robust than the 



fourth arcuatus^ 



Sixth and seventh joints of funicle both elongate, equal. 



angiistulu§» 

 Antennal scape just attaining the anterior margin of the prothorax. 



§etosus. 



These characters appear to be but slightly affected by sex. The 

 shallow fovea mentioned by Dr. Horn is visible in significans, 

 hrumalis, and arcuatus as a very broad, excessively feeble im- 

 pression on each side of the upper portion of the pronotum and 

 just behind the middle, but is entirely obsolete in angustulus 

 and setosus. S. obscurus Horn may possibly be included in the 

 above table, but the description of this species will apply more 

 or less satisfactorily to several; I, however, believe it to be unre- 

 presented in the material before me, as the posterior band of the
