Male. Ochraceous. Head and legs bright red. AntennsB 

 black, stout, very minutely serrated. Abdomen extending for 

 much more than half its length beyond the hind wings. Legs 

 stout, rather short; tibiae without spurs; tarsi blackish. Fore 

 wings long, slightly rounded at the tips, with two bright red
