ANNETTE F. BRAUN. 291 



densely dusted with brown scales, forming a large apical spot. Marginal line in 

 the cilia brown. Cilia pale brownish gray. Expanse 7-7.5 mm. 



Hindwings and cilia pale reddish brown. Abdomen and legs dark brown. 

 Hind tarsi whitish, except the first two joints, which are brown tipped with 

 white. 



Massachusetts. 



According to Frey and Boll, the food plant of this species is 

 Robinia Pseudacacia L., the mine being on the upper side of the 



leaf.

Face and palpi whitish gray. Antennae gray, annulate with dark brown. 

 Tuft dark brown mixed with a few whitish scales. 



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

 times more golden beyond the fascia. Remainder 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-third. 

 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. 



Eastern U. S., west to Colorado and Texas. 



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

 Falcata comosa (L.) Kuntze (= Amphiearpa monoica L.). 



The white basal streak, confluent with the first dorsal streak 

 separates this species from both robiniella and uhlerella.
