 Syii. nnif'tsciella Chambers (not Teiigstrom), Cin. Quart. Jn. Sci., ii, 103, 1875. 



Anteunfe gray, banded with dark brown above. Face and palpi wliitish, with 

 a faint ocherous tinge. Tuft reddish orange, paler in the center. 



Thorax and forewings reddish orange. Near the middle of the wing is an 

 obtusely angulated silvery fascia, margined on the costa before with a brown 

 spot, and strongly dark margined behind. This dark margin is produced back- 

 ward along the costa, and as a broad band along the middle of the wing. These 

 two streaks of dusting are connected at the beginning of the cilia, and are also 

 sometimes confluent with the apical dusting, which is dark brown on a paler 

 ground, and extends to the tornus. No costal nor dorsal streaks. A dark brown 

 line runs through the middle of the cilia, which are brownish ocherous, becom- 

 ing gray at the tornus. Expanse 6-7 mm. 



Hindwings and cilia gray, with a slightly reddish tinge. Abdomen gray. 

 Hind tarsi tipped with black. 



The oval blotch mines are found upon the upperside of various 

 species of oak. Ohio and Kentucky.

 Syn. caatanella Walsingham, Ins. Life, iii, 329, 1891. 



Antennae gray, banded above with dark brown. Face and palpi tinged with 

 ocherous. Tuft reddish orange, paler in the middle. 



Thorax and forewings reddish orange. At the basal third is a small white 

 spot, margined behind with black scales. At the middle of the wing is an 

 obtusely angulated, nearly straight fascia, dark margined behind and sometimes 

 on the costa before. At the angle of the fascia the dusting is produced back- 

 ward along the middle of the wing, uniting with that which forms the external 

 margin of a white costal streak at the beginning of the cilia. Opposite this 

 streak the position of a dorsal streak is faintly indicated. A small, white spot 

 just before the dusted apex. Sometimes the dusting behind the fascia and at the 

 apex is almost entirely lacking. A dark line through the middle of the cilia, 

 which are brownish ocherous, shading to gray at the tornus. Expanse 6-7.5 mm. 



Hindwings and cilia gray, the latter with a reddish tinge. Abdomen dark 

 gray. Hind tarsi tipped with black. 



Ohio and Kentucky. 



The mine occurs upon the upperside of leaves of chestnut and 

 various species of oak, and is a somewhat oval blotch. In this 

 species the larva hibernates on a slight bed of silk beneath the 

 folded epidennis.
