 Cilia almost entirely pure white. Hind wings and cilia pale silvery 

 gray. 



Legs pale grayish ocherous, tarsal joints dark tipped. Abdo- 

 men purplish fuscous above, paler and iridescent beneath in the 

 female.

Ten specimens bred at Cincinnati, O., from blotch mines on 



Hicoria minima (Marsh.) 

 Britton. The mine is at 

 first an extremely narrow 

 linear tract, later suddenly 

 expanding into a broader 

 tract, 1 mm. or more in 

 width, which in turn be-

width from 3 to 6 mm. 

 The mine is almost transparent even in the early linear portion, 

 which thus distinguishes it from that of N. juglandifoliella Clemens, 

 on hickory. This is the large blotch mine to which Chambers 

 refers (Psyche, III, 66, 1880). The larva is of a dull grayish colour 

 Cocoon reddish brown. 



There are two generations a year, the mines of the first ap- 

 pearing during the early part of July and producing imagoes during 

 the first week of August. The mines of the second generation may- 

 be "collected at the beginning of September. Up to this time I have 

 found the mines only on the single species of hickory noted above, 

 and never on Carya alba, as Chambers says. 

 Types in my collection.
