Corpus metallicum, immaculatura. Antennae sat late pectinatae.

Empyreuma, Hubn. Verz. Schmett. 120. 



Differs from the preceding group by the longer, and spotted, 

 and less hairy body, by the less deeply pectinated antennae, and by 

 less ample, and wholly opaque and unspotted wings. 



Body metallic. Antennae setaceous, much more than half the 

 length of the body, thickly and rather deeply pectinated to the tips. 

 Wings long, moderately broad, wholly opaque and squamose, not spot- 

 ted. Hind wings not angular. Abdomen nearly linear, not petio- 

 lated. Legs stout, not plumose. Tibiae with short spurs. This 

 group approaches nearest to Zygoma in its form, and in the colour 

 of its wings.
