 base and extreme tip. Antennae blackish, faintly marked with 

 narrow paler annulations. Head yellowish gray. Thorax gray, 

 patagia whitish, sparsely speckled with fuscous. Fore wings fus- 

 cous, a little dusted with yellowish white, especially in the basal 

 third. At base of dorsum a yellowish white patch, not extending 

 onto the costal half of base, is specked Avith a few fuscous scales; a

 tip. CiHa gray. Hind wings and cilia pale fuscous. Legs fuscous, 

 tips of segments and a bar across basal third of hind tibiae yellowish 

 white. Abdomen grayish above, yellowish white beneath. Ex-

Type ( 9 ), Glacier Park Station, July 29, in dry meadows. ■ 

 This species may be distinguished from all other species with 

 white at the base of the wing by the dull yellowish white of the 

 markings and the position of the basal pale patch, which is confined 

 to the dorsal half of the wing. Venation as figured in Meyrick's 

 "Handbook."

 pendicular transverse spot nearly reaching the fold, in a line with 

 this spot a small roundish spot below the fold, a spot at tornus and 

 farther out, a curved costal streak, sometimes nearly enclosing the 

 apex. Hind wings and cilia brownish gray. Underside of body 

 silvery. Legs dark brown, femora, apex and spurs of tibiae, and 

 tips of tarsi of the hind legs silvery. Expanse, 7 mm.
