shading along its edges into reddish bronze. Beyond this, wing deep purple 

 with bronze reflections; wing crossed at three-fifths its length by a straight, 

 shining, silvery or pale golden fascia. 3.5 mm. 



Ohio ; Kentucky ; Missouri. 



The larvae make contorted, serpentine mines on the upper side of leaves of poison 

 ivy (Rhus toxicodendron). 



There are three generations; mature larvse may be found in June, toward the 

 end of July, and .in September. 



11. Nepticula terminella Braun. Tuft on the face dull brownish, on the vertex 

 and head black; collar and eye-caps shining white, with a very faint yellow tinge. 

 Thorax bronzy. Costal half of the fore wing to the fascia, blue-purple, the blue 

 predominating at the extreme edge; below the costa the wing shading into a deep, 

 brilliant, golden color, becoming more bronzy as it nears the fascia. Fascia 

 situated just beyond the middle of the wing, almost straight, and with a brilliant, 

 silvery luster. Apical third of the wing blue-purple, blue predominating. Just 

 below the apex a double row of silvery scales margining the termen, becoming a 

 single row toward the dorsum, and sometimes connected with the fascia. 5 to 

 5 . 5 mm. 



Ohio ; Kentucky ; Pennsylvania. 



The mine is seen on various species of oak, though most commonly on red oak 

 (Quercus rubra) and pin oak (Q. palustris) , it is a pale greenish, gradually 

 broadening, linear tract, 3.5 mm. wide at the end. The larva is yellow, even when 

 very young. Thus this mine can early be distinguished from the other linear 

 mines on oak. 



There are three generations a year, and in favorable seasons, a fourth. 



12. Nepticula villosella Clemens. Tuft orange -ochraceous; eye-caps pale golden. 

 Thorax and fore wings to the fascia brilliant, metallic bronzy, somewhat purple 

 at the base of costa; fascia at two-thirds golden. Wing beyond the fascia blue- 

 purple, with a large spot at the apex and the apical cilia golden, concolorous with 

 the fascia. 4.5 mm. 



The larva is a miner in leaves of blackberry (Ruous spp.) and occasionally wild 

 raspberry (Rubus occidental-is). The mine is a tortuous, brown, linear tract 

 scarcely broader than the pale brownish larva within. 



There are three generations. 



This is distinguished from all other species by the metallic golden apex. 



13. Nepticula resplendensella Chambers. Palpi whitish, tuft pale reddish saf- 

 fron. Fore wings, including cilia, with a brilliant metallic luster, golden or silvery, 

 except the basal half of the costal margin, and a large spot extending along the 

 base of the costal cilia nearly to the tip and more than half way across the wing, 

 which is deep purple. Tips of tarsi pale yellowish. 6 mm. 



Kentucky. 



14. Nepticula unifasciella Chambers. Head orange -ochraceous; eye-caps silvery 

 white. Upper surface of thorax and basal two-thirds of fore wing brilliant metallic 

 bronzy or golden, except toward the costal margin where the color shades into 

 purple, so that a silvery or golden fascia at the apical third is scarcely defined 

 internally.. Behind the fascia, wings deep purple. Cilia purple, golden at their 

 tips. 4.5 mm. 



Kentucky; Texas; Ohio. 



15. Nepticula purpuratella Braun. Tuft ochraceous or orange; eye-caps silvery 

 white. Thorax deep bronzy or golden. Extreme base of the fore wing concolorous 

 with the thorax, shading outwardly to a paler, lustrous, golden color, and this, 

 at the outer limits of the basal third, followed by a deep, bronzy band with purple 

 and reddish reflections varying in intensity, and occupying approximately the 

 middle of the wing. This followed by a brilliant, silvery fascia. Apical area 

 beyond the fascia deep bronzy, usually suffused with brilliant purple. The purple
