 impunctured ; stemmaticum, flagellum, excluding the pedicel, 

 eyes, grooved lines on thorax, sometimes the sides of metathorax, 

 and the apical margins of the abdominal segments dark brown ; 

 the middle of abdomen sometimes wholly brown ; scape, pedicel,

 2 nearly twice as long as thick, the third slightly shorter and 

 stouter ; while the club is ovate, 3-jointed, and stouter than the 

 last funicle-joint. In the male the stemmaticum, occiput, a broad 

 median band on thorax, metathorax, and abdomen are brownish 

 black ; the flagellum is long, filiform, pilose, with the funicle-
