The original description is as follows : 



"Expanse 21 to 26 mm. 



"Palpi, front and vertex mottled light brown and white ; antennae whitish 

 with very fine brown annulations. , 



"Anterior part of thorax buff, this color spreading out into the base of 

 costa of primaries, somewhat darker and narrower in females than males. 

 Thorax dorsally brown, becoming lighter basally. Abdomen light brownish 

 butr on anterior part with a red-brown squarish spot close to base, becoming 

 quite dark, almost seal brown, mottled with ligher on the anal segments. 



"Fore-wings : Ground color white, the costal edge, discal area from base 

 to cleft, and inner margin broadly brown-streaked, the spaces between being 

 more or less suffused with light brown scales. A dark brown costal streak just 

 above the base of the cleft, connected broadly with the outer end of the discal 

 streak, preceded and followed by white; another brown costa! streak at the 

 base of the first lobe occupying about one-half the space then narrowly white 

 to apex. Extreme tip dark, two short dark longitudinal streaks, rather faint, 

 near the base of the lobe. A white spot resting on the base of the cleft con- 

 nected obliquely by a fine white line to the outer costal white spot. Second 

 lobe brown at tip, a faint brown line down the center, a small rectangular 

 white spot on vein lb at about one-third from the base. Fringe smoky, a whitish 

 spot at anal angle, darker within the cleft, a very dark spot a little inward from 

 tip of first lobe. 



"Hind wings dull smoky brown with a faint reddish tinge and darker 

 fringes. 



"Legs white more or less mottled with light brown, a small brush of 

 appressed brown scales at end of fore tibia. The middle tibia shows the same 

 development and in addition has a small cluster of long scales at the center. 

 Hind tibia as the middle, but a little more prominent. Spurs light at base, 

 smoky at tip. 



"In many specimens the scale clusters on tibiae become more or less obso- 

 lete, being represented by a slight swelling of the member at middle and end "
