  ## Description
  
  The male flies during the day. Its palpi are short, porrect (extending forward), and heavily fringed with hair. The antennae have long branches and long spines at the extremities. The legs are heavily hairy. The abdomen has a dorsal tuft on its second segment. The forewing has vein 9 arising from vein 10 and anastomosing with vein 8 to form an areole. The hindwing has veins 3 and 4 from angle of cell, vein 5 from just above angle, and vein 6 and 7 stalked.
  
  In the female, the palpi and legs are less hairy. The antennae are serrate. The wings are aborted, scale-like and covered with hair. The abdomen is covered with hair and immensely dilated when full of eggs.
