the third; a fine, vertical, white stripe across the apex, usually interrupted in 

 middle. Fringes white, the costal and dorsal each with two black lines, which con- 

 verge to the apex. Apex black, but not caudate; first dorsal line interrupted just 

 below the apex. 



Larva in a digitate mine on locust. 



Pennsylvania to Missouri; New York: Ithaca (mines not rare). 



3. P. lespedezaefoliella Clemens. Similar; first costal fascia absent; dorsal fasciae 

 reduced to spots (mirabilis Frey and Boll). 



Larva on Lespedeza and perhaps Desmodium, marking several small, digitate 

 mines; the frass thrown outside through a hole on the under side. Cocoon white, 

 outside the mine, often on the ground. 



Pennsylvania. 



4. P. pennsylvaniella Engel. Rich golden brown; head white; vertex light brown, 

 white above eyes; palpus white, with most of second segment and a spot on third 

 brown; apex of second segment white; maxillary palpi dark, with terminal joint 

 white. Scape of antenna brown above, white below, without fine stripes. Fore 

 wing with three strong silvery fascia? on costa, outwardly oblique; the first fascia 

 hardly if at all shorter than the other two; and a short, triangular, white spot 

 before the apex. Dorsal margin with a strong, nearly longitudinal dash from 

 near base to fold a quarter way out; two oblique fascia? before and beyond middle, 

 and a white bar in fringe opposite the last costal spot. All fascia? edged with 

 black. A black and blue ccellate spot just below and before apex. Fringe with 

 a strong black hook in the apex, with a white area below it, preceded by a black 

 line across the extreme apex of the membrane; dorsal fringe below the white patch 

 gray, not barred. 9 mm. 



May, August, October. Larva on Aster cordifolia; the mine large and inflated 

 when mature. 



Connecticut to western Pennsylvania. 



5. P. plantaginisella Chambers. Golden brown, lighter than P, pennsylvaniella, 

 the markings more heavily black-edged. Head bronze-brown, with a little white 

 above the mouth and along the eyes; palpi bronze on outer side, mostly white 

 within; thorax as in the proceeding species. Fore wing with the three costal 

 fascia? almost half as wide as the space between them; a subapical silver dot, with 

 a white bar in the fringe opposite it; inner margin with basal dash in fold, a short 

 silver bar at middle, and a longer one three-fourths way to apex, with its tip 

 almost touching the third costal one. A strong silver subterminal spot, opposite 

 the tip of the third costal, continued by a white bar in fringe. Apical ocellus 

 with a large silver center. Fringe black, strongly caudate, with a white triangle 

 below the apex. 7 mm. (erigeronella Chambers, geiella Chambers). 



September to November. Larva in a yellowish mine, which is at first slender 

 and frass-filled, but later becomes a large inflated blotch; on Erigeron and Plan- 

 tago. Pupa on the ground. 



Kentucky; Missouri.

 absent, Mj absent, M 2 and M 3 short stalked; Cu single -branched; 2d A simple. 

 Hind wings about one-half as wide, linear-lanceolate; M a and M 2 stalked; the 

 base of M sometimes distinct; M 3 absent; Cu single -branched; discal vein absent 

 between Cu and M : . Posterior tibia? with loosely appressed hairs.
