 liyaliue, venation pale. Forewings rather long; discal cell as long as pedicel ;

 bearing yellow bristles; pronotum yellow, with short yellow hair, and longer 

 black bristles; thorax black; abdomen brown; legs all very pale yellowish, 

 spines black. Wings heavily mottled with brown, except on costal area, the 

 bases of ai)ical cells ])aler, a large thyridio-discal spot, one in apex of subapicals, 

 most of the hyaline spots confluent, in general marked like G. mcestus. The supe- 

 rior appendages of the female are two long slender ajjproximate plates, the lower 

 appendages more slender and projecting beyond upper. Expanse 28 mm. 



Pullman, Washington State (Piper). A male from Wellington,
