The antenne of the male are 39-jomted, with fifty-eight rays on 
each side (four from each of the twenty-nine or thirty basal joints), 
the rays lying nearly flat. 
The antennz 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 antennee becoming gradually more slender 
to the tips. The palpi are short, but distinct and deflexed.
