The antennae of the male are 39-jointed, with fifty-eight rays on 

 each side (four from each of the twenty-nine or thirty basal joints), 

 the rays lying nearly flat. 



The antennae of the female are about 42-jointed, only slightly 

 serrated, each joint having two serratures on each side, the basal one 

 being most prominent, the antennae becoming gradually more slender 

 to the tips. The palpi are short, but distinct and deflexed.
