articulus 3us lanceolatus, subdecumbens, 2o valde brevior et gra-

Female, Body hardly stout. Proboscis distinct. Palpi long, 

 porrect, smooth, squamous, hardly curved, about as long as the tho-

 more slender than the second, with which it forms an extremely ob-

 rather beyond the hind wings. Legs smooth, slender. Fore wings 

 narrow, iridescent, somewhat rounded at the tips. Hind wings
