 profile, narrow, at base of antennae somewhat broadened, equal in breadth to width of third 

 antennal segment. Antennae long and slender, reaching nearlj^ to level of oral margin; 

 third antennal segment three times as long as wide; arista pubescent, as in befarum, but httle 

 thickened basad. Thorax with but few accessory setulae; acrosticals paired irregularly into
