Face and palpi whitish gray. Antenna' gray, annulate with dark brown. 

 Tuft dark brown mixed with a few whitish scales. 



Thorax and inner margin of the forewings beneath the fold dark brown, some- 

 times more golden bej-ond the fascia. Eemainder of the wing golden brown, 

 markings bright shining silvery. In the fold is a silvery basal streak, uniting 

 with the upper side of a nearly perpendicular white dorsal streak at one-tliird. 

 A little beyond this on the costal margin is a somewhat oblique streak dark mar- 

 gined on both sides. About the middle of the wing, is a slightly convex or 

 obtusely angled fascia dark margined internally and, on its costal half, exter- 

 nally. Beyond this are two perpendicular costal streaks dark margined inter- 

 nally and the former also externally. Opposite to the first of these costal streaks 

 is a dorsal streak whose apex sometimes meets that of the costal. In the fold 

 between this streak and the fascia is a velvety black streak. Opposite the last 

 costal streak, there is sometimes a small silvery dorsal streak. Apical spot 

 black, varying in size, sometimes occupying the entire apex of the wing. Cilia 

 gray, becoming darker toward the tornus; marginal line blackish. Expanse 

 6-7 mm. 



Hindwings and cilia gray. Abdomen brownish gray above, somewhat me- 

 tallic. Legs and tarsi gray, banded with white.

This species may be bred from whitish mines on the under ^^ide of 

 Falcata cornosa (L.) Kuntze (= Amphicarpa monoica L.). 



The white basal streak, confluent witli the first dorsal streak 

 separates this species from both rohiniella and uJilerella.
