292 AMERICAN MICRO-LEPIDOPTERA. 



Syu. amorphxella Chambers, Bull. Geol. Surv. Terr., iii. 132, 137, 1877. — amorphie 

 Frey and Boll, Stett. ent. Zeit., xxxix, 275, 1878. 



Face and ])alpi whitish gray. Antentise gray, annulate with dark brown. 

 Tuft brownish. 



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

 golden behind. Ground color of the remainder of the wing golden brown. The 

 first costal streak at the basal third is somewhat oblique and dark piargined on 

 both sides. A little nearer the base is the more perpendicularly placed first dor- 

 sal streak. About the middle of the wing is a curved or obtusely augulated 

 white fascia, dark margined internally and toward the costa externally. Beyond 

 this are two nearly perpendicular white costal streaks, dark margined internally, 

 of which the former is opposite a white dorsal streak, just before the tornus. In 

 the fold, between the fascia and this dorsal streak, is a black streak. A black 

 apical spot sometimes elongate. Cilia grayish, with a blackish marginal line. 

 Expanse 6-6.5 mm. 



Hindwings and cilia brownish gray. Abdon)en dark brownish gray. Legs 

 gray, hind tarsi whitish toward their bases. 



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



The whitish rather flat mine of this species occurs on the under 

 side of leaves of Amorpha frutlcosa L. 



Uhlerella may be distinguished from rohiniella by the presence 

 of the first white dorsal streak, the complete median fascia, and the 

 less oblique position of the streaks. It differs from morrisella by 

 the absence of a white basal streak.

Face and palpi silvery ; anteniiie and tuft dark brown, the latter mi.xed with 

 gray. Thorax dark brown. 



Forewings golden above the fold, dark gray dusted with black below the fold, 

 this dark shade extended to the costa at the base, becoming more golden toward 

 the tornus. Four rather large silvery costal streaks, the fu-st two oblique. 

 Opposite to the first of these, which is placed before the middle, and is dark mar- 

 gined on both sides, the position of a first dorsal streak is indicated by a some- 

 what lighter shade. The second at about the middle, also dark margined on 

 both sides, nearly unites at an angle with an opi)osite white dorsal streak, daik 

 margined internally. A white costal streak at three-quarters, margined inter- 

 nally with a curved black Hue, nearly unites witli an opposite internally mar-
