The sfutellum is consj)icuously clothed with white })ubescence, the 

 median line more or less denuded. The punctuation also is variable, 

 and those sj)ecimens described by LeConte as ()rer/oiieiisij<, and Casey 

 as obfit.^ii.-<, in which the pubescence of the scutellum is amply divided 

 by the median glabrous line, and that of the elytra more evidently 

 arranged in small jiatches nuiy indicate a race that is being differ- 

 entiated in the Pacific States ; at present the differences seem evan- 

 escent.
