The antennae of the male are moderately broad and flat, with fifty- 

 two rays on each side ; the four or five terminal joints very short, and 

 not producing any rays ; the rays are for the most part of nearly equal 

 length, so that the broad part of the antennae has its sides nearly 

 parallel. 



The antennae of the female are compressed, and with scarcely any 

 rudiment of pectinations. 



The palpi are distinct, but very short. 



The outer margin of the fore-wings of the female is entire.

The male antennae are moderately broad, with 126 rays on each 

 side, afiixed obliquely, the joints being very short, the ten terminal 

 joints very short, with only one ray on each side, gradually diminish- 

 ing in size. 



The female antennae are slightly serrated, each joint emitting two 

 oblique serrations on each side, the basal pair being the largest, the 

 size of the serrations gradually diminishing to the tip. 



The palpi are short and broad, but do not extend beyond the hairs 

 of the face. 



I have seen a variety from the Zoolu country much varied with 

 yellow, especially on the thorax, at the base of the wings, and along 

 the apical portion beyond the subapical striga.
