 eyes hairy; antennae rather short, six-jointed; the scape spindle- 

 shaped and approximately as long as the pedicel and three funicle 

 joints combined; pedicel about twice as long as broad at apex and 

 not quite as long as the entire funicle; first two funicle joints sub- 

 equal and each approximately twice as broad as long; third funicle 

 joint distinctly shorter than the pedicel but hardly one and one-half 

 times as long as broad; club approximately equal to the scape in
