Proboscis fully developed ; palpi obliquely upturned, slenderly scaled, the 

 2nd joint hardly reaching middle of frons, the 8rd short ; Irons with large 

 rather pointed conical prominence with corneous plate below it produced to a 

 point in front; eyes large, round; antennae of male almost simple; thorax

 from just above lower angle of cell; 6, 7 from upper angle; 8 anastomosing 

 with the cell to middle.
