Expanse of wings, 24-30 mm. Head and thorax brassy 

 brown ; palpi brownish cinereous. Fore wings golden fus- 

 cous, with a broad silvery- white stripe, bordered by a fine 

 dark line, extending outward from the base and ending in a 

 point near the subterminal line ; basal stripe narrow, less 

 than half the width of the white stripe at the costa. A very 

 small tooth in the middle on the lower side ; a very small, 

 spindle-shaped white spot above the outer end of the white 

 stripe, sometimes connected with it ; subterminal line brown- 

 ish, edged outwardly by a silvery streak, arising from the 

 outer fourth of the costa, forming an angle near the point of 

 the white stripe, thence running straight across the wing and 

 terminating just within the anal angle ; from the end of the 

 white streak a pale yellowish stripe extends outward to the 

 terminal line, curving upward to the apex, above which is a 

 brown triangular patch separated from the costa by a small 

 white triangle. Subterminal space below ashy brown, with 

 four or five indistinct black dashes. Terminal line golden 

 fuscous. Fringes grayish metallic, white at base above.
