"Antennse closely aDnulated with white and brown, the brown annulations 

 somewhat wider apart toward the apex. 



"Palpi silvery white, with a small spot on the outer side. Head, face silvery 

 white; frontal tuft saffron, mixed with white. Thorax golden saffron, poste- 

 rioily whitish. 



"Forewings golden saffron, shading to golden brown, no basal streak, three 

 costal and three dorsal snow-white spots, the first two pairs internally dark mar- 

 gined ; the first costal spot is situated at about one-third the length of the wing, its 

 internal dark margin ])assing around its apex; the corresponding dorsal spot com- 

 mences nearer the base of the wing and sometimes reaches obliquely to, or near, 

 the point of the costal spot; the second costal spot at half the wing length is 

 somewhat oblique, square ended, and as in the case of the first is placed some- 

 what beyond its smaller corresponding dorsal spot, which is pointed and has 

 some dark fuscous scales running outwardly from its apex and merging in the 

 darkened lower margin of the costal spot above it ; the third costal spot at one- 

 fourth from the apex is somewhat triangular and lies also farther from the base 

 than the corresponding smaller spot on the dorsal margin ; before the anal angle 

 between these spots, lies a cloud of fuscous scaling serving to throw up and make 

 more conspicuous these white markings on the golden brown ground color of the 

 wing; inclosing the apex of the wing is a narrow, outwardly concave white 

 streak, not reaching through the cilia on the apical but only on the costal mar- 

 gin ; beyond it are a few darkened scales and sometimes one on two whitish ones 

 with them; cilia pale, golden saffron, tending to golden; gray about the anal 

 angle. The only conspicuous markings on the under side are two pale spots in 

 the costal fringes, corresponding with the last two markings on the upper side. 



" Hindwings grayish, with golden gray cilia. Abdomen gray, anal tuft slightly 

 paler. Hind tarsi grayish white, with one or two darker bands above. Expanse 

 10-11 mm." 



The above is Lord Walsingham's description. 



Western United States and British Columbia (Rev. George W. 

 Taylor). The mine, on the upper side of Gaidtheria i<hallon, is a 

 large, somewhat irregular blotch, occupying about halt" the leaf. 

 When mature, the leaf i,s slightly folded and the epidermis lies in 

 two fine ridges across one end of the mine.
