Fore wings dark fuscous with pronounced purple and blue 

 reflections, shading to bronzy green below the fold. At three-fifths 

 is a broad very shining silvery fascia with faint golden lustre. 

 Cilia gray, extreme tips pearly white. Hind wings and cilia gray. 

 Legs dark fuscous, except the middle pair, which are silvery. 

 Abdomen purplish fuscous above, paler beneath in the female. 

 Expanse: 3.5 mm. 



Eleven specimens bred from mines on Opulaster (Opulaster 

 opiilifolius (L.) Kuntze) at Cincinnati. The mine is a narrow 



linear brown tract with a dark line 

 of frass running through it. The 

 cocoon is reddish brown, its an- 

 terior end broader and flattened. 

 On July 13th the larvae were nearly 

 full-fed, and all pupated within a 

 few days. The imagoes appeared 

 July 29th to August 4th. ' 



This species resembles N. roscr- 

 foliella Clemens, but differs from it 

 in the smaller size, the narrower 

 more lustrous fore wings and the 

 much broader fascia. 

 Types in my collection. 



Nepticula terminella n. sp. 



Palpi dull, pale ocherous gray. Tuft on the face dull brownish. 

 on the vertex and head black. Antenna? gray, 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 

 shades into a deep brilliant golden color, becoming more bronzy as 

 it nears the fascia. The fascia is situated just beyond the middle 

 of the wing, is almost straight and has a brilliant silvery lustre. 

 Apical third of the wing blue purple, blue predominating. Just 

 below the apex a double row of silvery scales margins the termen, 

 becoming a single row toward the dorsum and sometimes connected 

 with the fascia. Cilia gray. Hind wings and cilia gray, with a 

 purple tinge.
